Use nfsscan to produce a tabularized summary of each + 300-second segment of the trace. For these examples, + we'll call this DEFAULT_TABLE. + + Depending on what you're looking for, the default + settings of nfsscan might not provide all the info + you're going to want in the next step. The default is + to omit per-client, per-user, per-group, and per-file + stats and only tally total operation counts. [THE + DEFAULTS MAY CHANGE IN A FUTURE RELEASE.] + + 2. Use ns_timeagg to create a summary of activity in the + entire trace named SUMMARY_TABLE from DEFAULT_TABLE. + + Note that almost anything ns_timeagg and ns_split can + do can also be done directly with nfsscan. However, + the implicit goal of ns_timeagg and ns_split is to + AVOID re-running nfsscan. It is much faster to + re-process a table created by nfsscan than it is to + re-create the table -- the input to nfsscan is + typically several million (or billion) lines of trace + data, while the output is usually only a few thousand + table rows. + + 3. Use ns_quickview to plot interesting aspects of the + DEFAULT_TABLE and/or SUMMARY_TABLE. + + 4. [optional] Use ns_split and/or ns_tsplit to isolate + interesting parts of DEFAULT_TABLE (such as per-client + or per-user counts). Repeat steps 2 and 3 with the + results. + + 5. [optional] If steps 2-4 found anything interesting, re-run + nfsscan with new parameters to take a closer look at + the trace. + +Examples and discussion of these steps and related topics is given +below. + +For these examples, TRACE is a trace file gathered by nfsdump (or +another tool that creates traces files in the same format), and TABLE.ns +is a file created by nfsscan from TRACE. The suffix ".ns" is also +used to denote files that contain tables created by nfsscan, +ns_timeagg, ns_split, and ns_tsplit. Example commandlines always +begin with "%". + +1. RUNNING NFSSCAN + +2. CREATING A SUMMARY TABLE + + To compute a table contsisting of a single row with counts for + each operation tallied by the nfsscan run, aggregate over time + with a time length of zero. (Zero is treated as a special + time length that includes the entire input table.) + + % ns_timeagg -t0 TABLE.ns > SUMMARY.ns + + Note that timeagg will always aggregate over every (except + time) attribute, so it does not matter whether or not the + TABLE.ns contains per-client, per-user, per-group, or per-file + data. The sum will always be the same. + + On the other hand, if you want to prevent ns_timeagg from + aggregating over a particular attribute, specify that + attribute in the same manner as with nfsscan. For example, to + create a table with a single row containing the operation + count per user: + + % ns_timeagg -t0 -BU TABLE.ns > SUMMARY.ns + + Of course, ns_timeagg cannot create data out of thin air. If + TABLE.ns does not contain per-user information then -BU will + have no effect. + +3. PLOTTING THE DATA + + To simply plot the total operation count: + + % ns_quickview TABLE.ns + % gv qv.ps + +WHICH CLIENT REQUESTS THE MOST OPERATIONS? + +Method: use nfsscan to tally the per-client operation counts for the + entire trace file (by using -t0), and then sort by the TOTAL + op count fields: + + If TABLE contains per-client information, then this is easy: + + % ns_timeagg -t0 -BC TABLE | grep -v '^#' \ + | awk '{print $7, $3}' | sort -nr + + If TABLE does not contain per-client info, then it's necessary + to re-run nfsscan: + + % nfsscan -t0 -BC TRACE | grep -v '^#' \ + | awk '{print $7, $3}' | sort -nr + + The output from either command is a two-column table. The + first column is the total operation count of each client, and + the second column is the ID of each client. + +WHICH CLIENT DOES THE MOST READING? + + If we've already got TABLE, and it contains per-client info, + then the easiest way is to simply use extract the read count + column (instead of the TOTAL column) from TABLE: + + % ns_timeagg -t0 -BC TABLE | grep -v '^#' \ + | awk '{print $9, $3}' | sort -nr + + Or, we can nfsscan. Because we're not interested in anything + except the read count, we can change the list of operations + that nfsscan tabulates so that it only counts reads. (Of course, + the resulting table is useless for anything except answering + this particular question, and since nfsscan is expensive to run + this is probably wasteful.) + + % nfsscan -t0 -BC -Oread -i TRACE | grep -v '^#' \ + | awk '{print $7, $3}' | sort -nr + +WHICH CLIENT DOES THE MOST FSSTATS? + + fsstat is not ordinarily tabulated by nfsscan. To tell nfsscan + to keep track of it, we can change the list of operations to consist + only of fsstat: + + % nfsscan -t0 -BC -Ofsstat -i TRACE | ... + + As mentioned in the previous example, it is often wasteful to + run nfsscan just to get one number. Another approach is to + add fsstat to the default list of "interesting" operations, by + using "+" at the start of the operation list. This tells nfsscan + to append the given list of operations to the default list: + + % nfsscan -t0 -BC -O+fsstat -i TRACE | ... + + An implication of this is that it's impossible to know what + each column in the table represents unless you know what + operations were considered "interesting" for each run of + nfsscan. To help with this, nfsscan includes the commandline + and column titles at the start of each file it creates. + +WHICH USER DOES THE MOST READING? + + This is exactly like the previous example, except that we use + -BU instead -BC, to do everything per-user instead of + per-client. + +WHAT DIRECTORIES ARE HOTTEST? + + Use the -d option to find the cummulative number of operations + per directory, then sort the results by operation count. In + order to avoid drowning in data you might choose to print + print only the top 100: + + % nfsscan -i TRACE -t0 -d | grep '^D' \ + | awk '{print $7, $5}' | sort -nr | head -100 + diff --git a/TBBT/trace_init/INSTALL b/TBBT/trace_init/INSTALL new file mode 100755 index 0000000..6849497 --- /dev/null +++ b/TBBT/trace_init/INSTALL @@ -0,0 +1,61 @@ +# $Id: INSTALL,v 1.4 2003/07/28 14:27:16 ellard Exp $ + +NFSSCAN INSTALLATION INSTRUCTIONS + +This is version 0.10a of nfsscan, dated 7/25/2003. + +THIS IS A PRELIMINARY RELEASE OF NEW SOFTWARE: + +- THE COMMANDLINE FORMATS MAY EVOLVE RAPIDLY OVER THE NEXT SEVERAL + RELEASES. + +- DEBUGGING MESSAGES AND WARNINGS MAY APPEAR ON STDERR.

The "Count" table goes to basename.cnt, + "Latency" to basename.lat, and "File" to basename.fil. + The default is to write all output to stdout. + +-O op[,op]* Specify the list of "interesting" operations. + The default list is: + + read,write,lookup,getattr,access,create,remove + + If the first op starts with +, then the specified list + of ops is appended to the default list. The special + pseudo-ops readM and writeM represent the number of + bytes read and written, expressed in MB. + +-t interval Time interval for cummulative statistics (such as + operation count). The default is 300 seconds. + If set to 0, then the entire trace is processed. By + default, time is specified in seconds, but if the last + character of the interval is any of s, m, h, or d, + then the interval is interpreted as seconds, minutes, + hours, or days. + +-u u1[,u2]* Include only activity performed by the specified users. + +-U u1[,u2]* Exclude activity performed by the specified users. + +-Z Omit count and latency lines that have a zero total + operation count. + + +OUTPUT FORMATS + +Each line generated by nfsscan begins with a token that indicates the +table to which it belongs. + +COUNT LINES + +These lines all begin with 'C' (or #C, for comments), +and have the following format: + +C time client euid egid fh TOTAL INTERESTING + +time - The time of the start of the measurement interval. + +client - The IP number of the client. If the user has not + requested per-client statistics, this field is 'u'. + +euid - The effective uid of the caller, in decimal. If the user has + not requested per-user statistics, this field is 'u'. + +egid - The effective gid of the caller, in decimal. If the user has + not requested per-group statistics, this field is 'u'. + +fh - The file handle used by the operation. If the user has not + requested per-file statistics, this field is 'u'. + +TOTAL - The total number of operations for the given client, euid, + egid, and fh, for all the operations in . Note that + this is NOT the same as the total of all operations! For + example, if you set to the empty list, the TOTAL will + always be zero. + +INTERESTING - The total number of "interesting" operations. These are + either the default operations (listed below) or the whatever + set of operations the user specifies. + + + - Following INTERESTING, the count for each "interesting" + operation observed during the measurement interval is printed. + The list of operations can be specified or extended on the + commandline. By default, the list of operations is: + + read, write, lookup, getattr, access, create, remove + +LATENCY LINES + +The format for the "latency" lines is like that of the "count" lines, +except the lines all begin with "L" (or "#L") and each count +(including the TOTAL and INTERESTING counts) is followed the average +latency for that operation. If the count for a particular operation +is 0, then the average latency is shown as -1. + +Note that the counts for the latency lines may be (and often are) +different than the counts for count lines. This is because the count +lines show the number of calls that were observed, and the latency +lines require observing both calls and reponses. + +FILE LINES + +These lines show information about files, rather than information +about calls. These lines all begin with "F" (or "#F"). The file +information (size, mode, etc) are currently only printed for files, +not directories. + +The format is: + +F type state fh path dirs mode size atime mtime ctime + +type - Either "F" for file, or "D" for directory. + +state - "A" if the file is still alive at the end of the + trace, or "D" if the file has been deleted. + +fh - The file handle. + +path - as much of the file path as can be reconstructed from the + observed traffic. + +dirs - the number of directories in the path. + +mode - the most recently observed permissions on the file, in hex. + +size - the most recently observed size of the file, in hex. + +atime - last access time of the file + +mtime - last modification time of the file + +ctime - last file status change time + +DIRECTORY LINES + +These lines show operation count information for files and +directories. These lines all begin with "D" (or "#D"). Each line +begins with the following fields: + +time - The time of the start of the measurement interval. + +Dir/File - D for directory, F for file. + +dircnt - The length of the path to that directory, or zero for files. + +path - The path from the mount point to the directory or file. + +fh - The file handle of the directory or file. + +TOTAL - The total number of operations for the given client, euid, + egid, and fh, for all the operations in . Note that + this is NOT the same as the total of all operations! For + example, if you set to the empty list, the TOTAL will + always be zero. + +Following the TOTAL, the count for each "interesting" operation +observed during the measurement interval is printed. The list of +operations can be specified on the commandline. By default, the list +of operations is: + + read, write, lookup, getattr, access, create, remove + +The information for files is redundant because this information is +also reflected in the Count lines (if -BF is used), but it is +sometimes useful to have it in the same format as the directory info. + +The TOTAL and op counts for directories represent the total number of +ops for the files in that directory AND all of its subdirectories. + +NOTE: there are several potential problems with the directory information: + + 1. It is possible (and not uncommon) for some part of a path + to be missing from the traces. The path is + reconstructed as far back to the root as possible, but + this is not always successful. + + If no information about the name of a file is known, + then it is given the name ".". + + 2. If files are renamed during the trace, then the name shown + is the most recent name for the file. + + 3. If files are removed during the trace, they are still + reported in the summary. + + This can lead to an error: if a directory is deleted, + and then another directory is created elsewhere with a + new name but the same inode number, this new directory + can "inherit" all the info about the files in the old + directory, including parentage. In the worst case, + this can cause a loop. The program will detect such + loops, and therefore not get caught forever, but it + doesn't do anything clever about them. diff --git a/TBBT/trace_init/ns_loc2gmt.pl b/TBBT/trace_init/ns_loc2gmt.pl new file mode 100755 index 0000000..815f68f --- /dev/null +++ b/TBBT/trace_init/ns_loc2gmt.pl @@ -0,0 +1,108 @@ +#!/usr/bin/perl +# +# Copyright (c) 2002-2003 +# The President and Fellows of Harvard College. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# 1.

Why is a Poisson Distribution used in SFS, rather than, say a +Zipf distribution? + +A2. The reasoning behind the use of Poisson probabilities in SFS 2.0 +may be lost in the mists of time. Because SFS 2.0 was withdrawn by SPEC +before SFS 3.0 development had proceeded very far, there was considerable +time-pressure to release SFS 3.0 quickly. So we chose to patch the +existing Poisson probability calculations instead of implementing a new +distribution for file accesses. + +There is experimental data showing that a Zipf Distribution is a good +model for file access probabilities. The question of what distribution +to use in SFS 4.0 is open, so various distributions can be considered. + +Q3. Is it true that SFS 3.0 combines multiple Poisson cycles into a +single cycle that is also a Poisson Distribution? + +A3. The combination of the distributions follows the curve of a Poisson +Distribution only if you treat each of the twelve generations of +access-groups as a single outcome. + +Q4. Why did the calculation of "Io_working_set.access_group_cnt" change +between SFS 2.0 and SFS 3.0? + +A4. This calculation determines the number of access-groups in the I/O +working-set. The number of access-groups grows *roughly* in linear +proportion to the number of files, so that no access-group contains more +than 125 files. + +In SFS 2.0, 4 groups are added for every 500 files, but in SFS 3.0 +12 groups are added for every 1500 files, so the number of files per +access-group remains roughly the same. + +The main effect of the change is how the number of groups is rounded. +In SFS 2.0, the number of groups was rounded to a multiple of 4, +with a minimum of 8 groups. In SFS 3.0, the number of groups is +rounded to a multiple of 12 (the value of "generations") so that the +cycle of Poisson probabilities (for all 12 generations of access-groups) +will be completely repeated group_cnt/12 times with no groups left over. + +Q5. Why was the minimum number of access-groups changed from 8 to 12? +Why not, say, 24? + +A5. The choice was somewhat arbitrary. Here is some of the rationale: + +In order to get a complete set of Poisson probabilities, there must be +at least as many access-groups as generations. If we had generations=24 +instead of 12, then some of the group-probabilities would be zero due to +defect #2. (Recall that with 24 groups in SFS 2.0, 13% were inaccessible +due to rounding of the scaled probabilities.) In SFS 2.0, 12 was the +largest number of groups which did not trigger defect #2. Of course, +since we now know how to fix that defect, that wasn't the complete reason. + +Another consideration was that the number of access groups must be rounded +to a multiple of the number of generations. If we had used generations=24 +then the rounding would introduce a more radical change in the number +of groups, especially for large numbers of procs. + +On the other hand, if we had used generations=8 instead of 12, we would +have gotten very little variation in access probabilities, which seemed +against the intent of the benchmark design. + +Q6. Why is lambda being calculated differently in SFS 3.0? + +A6. Lambda is the parameter of the Poisson Distribution which determines +the shape of its probability density function, its mean, and other +characteristics. + +SFS 2.0 set lambda to half the number of groups, which in turn was a +function of the requested ops/sec/proc. That was defect #4, which caused +the shape of the access-distribution to change depending on how many +processes a vendor chose to use -- it would get narrower as the number +of processes was reduced. SFS 3.0 sets lambda based on "generations", +which is a constant. Thus the new distribution has the same shape no +matter how many load-generating processes are used. + +The key to defect #4 was that we *don't* want lambda to vary +with the number of access-groups. We want it to be a constant so that +for a given size fileset the number of files that fit into cache +depends very little on the number of load-generation processes used. + +Q7. Why was lambda set to half the number of groups in SFS 2.0 +instead of something else? + +A7. The SFS 2.0 rationale is not documented, as far as we know. The nice +thing about group_count/2 is that it puts the characteristic "hump" of the +probability density function (the mode) near group_count/2, in the middle +of the array of groups. Probably that was the reason. + +In SFS 3.0, each cycle of probabilities has 12 groups, so lambda=6 +to preserve this feature of the distribution. + +Q8. How is the SFS 3.0 approach differ from always using 12 access-groups +and allowing the number of files per access-group to be more than 125? + +A8. The end-result would have been roughly the same. The reason this +was not done was that SFS sometimes searches within an access-group, for +instance to find the best fit for an operation. The search is a linear +search. We were concerned that if the number of files in a group got +too large, the client could get bogged down searching for the best fit. +The search for the appropriate access-group is a binary search, which +scales better. + +Q9. Why not just limit the benchmark to 25 requested ops/second/process, +so that the number of groups would always be 12 or less? + +A9. Historically SPEC has given server vendors lots of leeway to +have as few processes as they wish, modulo the Uniform Access Rule and +the run-rule requirement for at least 8 processes per network. In the +interest of avoiding a long, drawn-out debate about adding a new run-rule +to arbitrarily limit ops/process, we decided to simply fix the code so +that it would work reasonably well for larger numbers of ops/process. + +Q10. Where did the new variable "cumulative_ratio" come from? + +A10. This variable is used in the loop that calculates Poisson distribution +for I/O working-set accesses. In 2.0, lambda^x and x! were calculated +separately. Both variables got very large and would overflow when 'x' got +into the hundreds. This was defect #3. The Poisson distribution really +only needs the ratio (lambda^x/x!), which is numerically more stable. +So that is what the SFS 3.0 code calculates. + +Since SFS 3.0 never uses values of lambda other than 6.0, the change +has proven to be moot. diff --git a/TBBT/trace_play/agefs b/TBBT/trace_play/agefs new file mode 100755 index 0000000..bdebf34 Binary files /dev/null and b/TBBT/trace_play/agefs differ diff --git a/TBBT/trace_play/agefs.log b/TBBT/trace_play/agefs.log new file mode 100644 index 0000000..d3fcb00 --- /dev/null +++ b/TBBT/trace_play/agefs.log @@ -0,0 +1,36 @@ + + +agefs Wed Apr 21 18:28:42 EDT 2004 + + +agefs Wed Apr 21 18:31:44 EDT 2004 +Wed Apr 21 18:31:44 EDT 2004 + + +agefs Wed Apr 21 18:32:06 EDT 2004 +Wed Apr 21 18:32:06 EDT 2004 + + +agefs Wed Apr 21 18:32:58 EDT 2004 +Wed Apr 21 18:32:58 EDT 2004 + + +agefs Wed Apr 21 18:33:15 EDT 2004 +Wed Apr 21 18:33:15 EDT 2004 +Wed Apr 21 23:18:15 EDT 2004 +Wed Apr 21 23:18:15 EDT 2004 +Thu Apr 22 00:08:24 EDT 2004 +Thu Apr 22 00:08:24 EDT 2004 +Thu Apr 22 00:33:15 EDT 2004 +Thu Apr 22 00:33:15 EDT 2004 +Thu Apr 22 00:33:33 EDT 2004 +Thu Apr 22 00:33:33 EDT 2004 +Thu Apr 22 00:35:06 EDT 2004 +Thu Apr 22 00:35:06 EDT 2004 +Thu Apr 22 00:35:16 EDT 2004 +Thu Apr 22 00:35:16 EDT 2004 +Thu Apr 22 00:36:25 EDT 2004 +Thu Apr 22 00:38:36 EDT 2004 +Thu Apr 22 00:39:17 EDT 2004 +Thu Apr 22 00:39:19 EDT 2004 +Thu Apr 22 00:47:43 EDT 2004 diff --git a/TBBT/trace_play/frag_collect b/TBBT/trace_play/frag_collect new file mode 100755 index 0000000..773e158 --- /dev/null +++ b/TBBT/trace_play/frag_collect @@ -0,0 +1,15 @@ +nfs stop +umount $1 +mount $1 +nfs start +cd $1 +echo "find test1 -print >$3.1" +find test1 -print > $3.1 +echo "sed -d s/^/show_inode_info / $3.1" +sed -e "s/^/show_inode_info /" $3.1 >$3.2 +echo "open $2" >$3.3 +cat $3.2 >> $3.3 +echo "debugfs -f $3.3" +debugfs -f $3.3 > $3.4 +#echo "frag_count $3.4 > $3.5" +#frag_count $3.4 > $3.5 diff --git a/TBBT/trace_play/frag_collect_cust b/TBBT/trace_play/frag_collect_cust new file mode 100755 index 0000000..24d9c62 --- /dev/null +++ b/TBBT/trace_play/frag_collect_cust @@ -0,0 +1,14 @@ +#This is to collect info for something other than test1 +#test1 is hard-coded in frag_collect +nfs stop +umount $1 +mount $1 +nfs start +echo "sed -d s/^/show_inode_info / $3" +sed -e "s/^/show_inode_info /" $3 >$3.2 +echo "open $2" >$3.3 +cat $3.2 >> $3.3 +echo "debugfs -f $3.3" +debugfs -f $3.3 > $3.4 +#echo "frag_count $3.4 > $3.5" +#frag_count $3.4 > $3.5 diff --git a/TBBT/trace_play/frag_count b/TBBT/trace_play/frag_count new file mode 100755 index 0000000..e1cdae0 Binary files /dev/null and b/TBBT/trace_play/frag_count differ diff --git a/TBBT/trace_play/frag_count.c b/TBBT/trace_play/frag_count.c new file mode 100644 index 0000000..a8d8397 --- /dev/null +++ b/TBBT/trace_play/frag_count.c @@ -0,0 +1,311 @@ +#include +#define RFS_ASSERT(condition) \ + if (!(condition)) { \ + fprintf(stderr, "Assertion failed: line %d, file \"%s\"\n", \ + __LINE__, __FILE__);

Second, run +.B SFS +at different loads of interest and +save the results. Third, change the server configuration (for example, +add more memory, replace a disk controller, etc.).

The write packets produced consist + * of 50% 8-KB packets, and 50% 1-7 KB packets. The read packets consist + * of 85% 8-KB packets, and 15% 1-7 KB packets. These figures are + * determined by multiplying the percentage for the type of transfer by + * the number of blocks and fragments generated, and adding the totals. + * These conmputations are performed below for the default block size + * distribution tables: + * + * Read blocks fragments + * 0 0 0 0 0 + * 85 1 0 85 0 + * 8 2 1 16 8 + * 4 4 1 16 4 + * 2 8 1 16 2 + * 1 16 1 16 1 + * --- --- + * 149 (90%) 15 (10%) + * + * Write + * 49 0 1 0 49 + * 36 1 1 36 36 + * 8 2 1 16 8 + * 4 4 1 16 4 + * 2 8 1 16 2 + * 1 16 1 16 1 + * --- --- + * 100 (50%) 100 (50%) + * + * + * + * + * + * NFS Operation Mix + * + * The operation mix is described assigning a percentage to each type + * of NFS operation. The default mix of operations is: + * + * operation percent + * --------- ------- + * null 0 + * getattr 13 + * setattr 1 + * root 0 + * lookup 34 + * readlink 8 + * read 22 + * wrcache 0 + * write 15 + * create 2 + * remove 1 + * rename 0 + * link 0 + * symlink 0 + * mkdir 0 + * rmdir 0 + * readdir 3 + * fsstat 1 + * + * The user may specify a a different operation mix by using the '-m' option. + * The format for the mix file consists of the output from an nfsstat(1) + * command, which lists an operation count and percentage for each NFS + * operation. + * + * + * File Set Size + * + * !!! needs to be re-written - mew 8/24 + * This still needs to be rewritten + * - The default number of i/o files is based on load level. + * - For non I/O files, the number of initialized versus empty + * slots is hardcoded + * - dr 2/8/94 + * + * The file set used by SFS is determined by 2 factors. First, + * SFS creates a base set of files. By default this consists of + * 100 files for i/o operations, 100 files for non-i/o operations, 20 + * directories, and 20 symbolic links. These default values can be + * changed from the command line by using the "-F", "-D", and "-S" options. + * This file set is divided evenly among the set of processes used to + * generate load. + * + * Then, enough resources are allocated to allow for the eventual creation + * of new files, directories and symlinks by the creat, link, mkdir, + * and symlink operations. The number of extra slots allocated depends + * on the mix percentages assigned to each of the create and deletion + * operations, multiplied by an estimate of the total number of operations + * to be performed. For instance, the default number of extra files names + * allocated for non-i/o operations is computed as follows: + * 300 secs * 60 ops/sec = 18000 total operations + * 2% create * 18000 ops = 360 create ops + * 1% remove * 18000 ops = 180 remove ops + * 260 creates ops - 180 remove ops = 180 extra files to be created. + * These 90 files are distributed evenly among the processes used to + * generate load. With the default settings, no extra directories are + * created or removed, so no extra allocation is done for directories + * beyond the base file set. The same is true for symbolic links. + * + * Thus, the total default file set size is: + * 100 files for i/o operations + * 280 files for non-i/o operations + * 20 directories + * 20 symlinks + * + * By allocating all required space before the test begins, any space + * allocation problems encountered by SFS are discovered before the + * test is started. + * + * + * Program Control + * + * Strategy: loop for some number of NFS calls doing a random sleep + * followed by a call to one of the op generator routines. The routines + * are called based on a weighting factor determined by the set of + * default percentages or a mix supplied by the user. + * + * The generator routines are able to keep an accurate count of the + * NFS operations they are generating by using the NFS protocol + * directly and not going through the kernel. This eliminates the + * effects of kernel name caches and retry mechanisms that + * complicate control of what actually hits the wire. The calling + * routine benefits by avoiding having to get the NFS statistics + * from the kernel because they KNOW what calls they've made. + * + * By using the NFS protocol directly : + * "lookup" operations sidestep the client kernel name cache, + * "getattr" operations avoid the client kernel attribute cache, + * "read" operations avoid the client kernel buffer cache, + * and so on. + * + * A consequence of not going thru the client kernel is that the sfs + * program must maintain a table of file handles rather than open + * file descriptors. + * + * The parent process starts children to do the real work of generating load. + * The parent coordinates them so that they all start at the same time, and + * collects statistics from them when they are done. To coordinate the + * start up, the parent waits for each child to write one byte into + * a common log file (opened in append mode to avoid overwriting). + * After they write a byte the children pause, and the parent send SIGUSR1 + * when it has heard from all of the kids. The children write their statistics + * into the same common log file and the parent reads and accumulates the + * statistics and prints them out. + * + * + *.Exported_Routines + * int main(int, char*) + * + *.Local_Routines + * void init_logfile(void) + * void usage(void) + * int setmix(char *) + * int setiodist(FILE *) + * int parseiodist(FILE *, int) + * void init_iodist(sfs_io_dist_type *) + * void init_fss(void) + * void init_filedist(void) + * int lad_substr(char *, char *) + * + *.Revision_History + * 21-Aug-92 0.1.11 Wittle File set access code. + * 14-Jul-92 0.1.9 Teelucksingh + * Implemented Mark Wittle's proposal to + * base File Set Size on peak load value, + * added "-L peak_load" option. + * 10-Jan-92 0.0.0.19 Teelucksingh + * Reworked setpgrp() usage to + * better handle BSD vs SYSV variations. + * 04-Jan-92 0.0.0.18 Pawlowski + * Added raw data dump code. + * 04-Dec-91 0.0.0.15 Keith + * Include string.h if SVR4. + * 28-Nov-91 0.0.0.13 Teelucksingh + * Modified code to use unique sfs /tmp + * logfiles; sfs can now be used on + * clients that have a shared /tmp area. + * Added ANSI C features.
