WLM command reference
wlmsend
Appendix A394
NOTE Be careful of I/O buffering when feeding data to wlmsend. For example,
the following line works as expected:
tail -f logfile | wlmsend job_time
However, adding awk or other utilities that buffer I/O can result in data
being delayed, or not even sent, to wlmsend—depending on when the
buffer is flushed:
tail -f logfile | awk ‘{print $1}’ | wlmsend job_time
Always check the file /var/opt/wlm/wlmdstats, created by wlmd -l
metric as explained in wlmd(1M), to ensure that your data gets to WLM
in a timely fashion.
For more information on wlmsend, see “Sending data with wlmsend and
wlmrcvdc: How it works” on page 509.
