| 2 | filehist - 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 | |
|---|
| 8 | tsfilehist.awk - Awk script for generating file space histograms on GPFS |
|---|
| 9 | filesystems. (Used by filehist script) |
|---|
| 10 | |

| 12 | trsum.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. |

| 36 | fsstruct.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 |

|---|
| 49 | Build a file with the names of all nodes in the GPFS cluster: |

|---|
| 51 | Gather /var/log/messages* from all nodes |

|---|
| 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 |
