Advanced WLM usage: Using performance metrics
Supplying data to WLM
Appendix H512
Figure H-3 wlmrcvdc: FIFO-file mode (wlmrcvdc)
In this next example, when the WLM configuration file is activated,
wlmrcvdc creates a rendezvous point, with a name based on the metric
name resp_time. The rendezvous point is owned by the user admin in
the group sys:
tune resp_time {
coll_argv = wlmrcvdc -u admin -g sys;
}
Now all that remains is for you to use wlmsend in a data collector script
to forward values to the established FIFO rendezvous point.
Figure H-4 illustrates the command-output mode of operation for
wlmsend. In this mode, wlmsend forwards its stdin to the rendezvous
point that wlmrcvdc monitors. wlmrcvdc then sends the data on to WLM.
