2filehist       - Shell script wrapper for generating file space histograms
3                 for all currently mounted GPFS filesystems
4                 (uses /usr/lpp/mmfs/samples/util/tsinode
5                  and  /usr/lpp/mmfs/samples/debugtools/tsfilehist.awk)
6                 Generates one file for each filesystem called $fsname.filesum
7
8tsfilehist.awk - Awk script for generating file space histograms on GPFS
9                 filesystems. (Used by filehist script)
10
11===============================================================================
12trsum.awk      - Awk script for analyzing a GPFS trace and reporting various
13                 statistics.
14
15                 Example to show application calls and IO performed.
16                     (The trace will wrap and only retain the records just
17                      before the stop. See mmtrace -? for other options to
18                      make the trace output larger.)
19
20                   mmtrace trace=io
21                   #run test program
22                   mmtrace stop  #produces file with prefix /tmp/mmfs/trcrpt.
23                   cd /tmp/mmfs
24                   for file in trcrpt.*; do
25                     echo $file
26                     trsum.awk $file > trsum.${file#*trcrpt.}
27                   done &
28
29                 The trsum output shows system call entry/exit and elapsed time
30                 along with arguments for each operation.
31                 (trsum.awk details=0 ...  to turn this part off)
32
33                 At the end of the report are summaries and performance histograms.

36fsstruct.awk   - Error report analysis on AIX clusters.
37                 Build a file with the names of all nodes in the GPFS cluster:
38                   mmcommon getNodeList|awk '{print $3}' > $WCOLL
39                 Gather errpt -a output from all nodes
40                   for node in $(<$WCOLL); do
41                     mmdsh -L $node errpt -a 2>/dev/null
42                   done > errpt.all &
43                 Then summarize the errpt.all file with one line per event:
44                   fsstruct.awk errpt.all  | sort -k1,1 > gpfs.err.summary
45                   fsstruct.awk all=1 errpt.all  | sort -k1,1 > all.err.summary
46

48fsstructlx.awk - Error report analysis on Linux clusters.
49                 Build a file with the names of all nodes in the GPFS cluster:
50                   mmcommon getNodeList|awk '{print $3}' > $WCOLL
51                 Gather /var/log/messages* from all nodes
52                   for node in $(<$WCOLL); do
53                     mmdsh -L $node 'cat $(ls -tr /var/log/messages*)' 2>/dev/null
54                   done > syslogs.all &
55                 Then summarize the syslogs.all file with one line per event:
56                   fsstructlx.awk syslogs.all | sort -k1,1 > gpfs.err.summary
57                   fsstructlx.awk all=1 syslogs.all | sort -k1,1 > all.err.summary
