The MQ handler is not enabled by default in the xymond_client module.
Change tasks.cfg to start xymond_client with
"--collectors=default,mqcollect"
OK, I have modified tasks.cfg for the regular client channel. Now the process command line looks like:
bb 16733 16729 0 17:16 ? 00:00:00 xymond_channel --channel=client --collectors=default,mqcollect --log=/var/log/xymon/clientdata.log xymond_client
Not yet seeing any change in the main BB page however (I may have to wait a bit for it to regenerate) but is this correct?
