I haven't implemented my solution in analysis.cfg so this may not be of any use to you. As my central BHX[1] server is a linux box I just run a script that looks in the $XYMSRV/data/logs directory for the <hostname>.procs files of the systems involved. Again, if you're not using a linux/unix central server this may not apply. The routine looks in the $XYMSRV/data/logs/ directory for the <hostname>.procs files of the systems involved. The logfiles are plain text so it scans through the first of the logfiles looking for the process name. If the script finds the process listed, the script scores two (add two to a $TEMPVAR). If it doesn't find a match, then nothing is scored. The script does this again for the second system this time score ONE if it gets a match, zero if there is no match. Now working out the service status is easy. If the score is either one or two then everything is "Green, OK". However if the score if either 3 or zero then "Panic!, Red". (Actually, this is a bit of a fib as my version of the script checks for the exclusivity of two separate processes on each system. Both processes have to be running on the same system, but only one system at a time. So I use the scores 1000, 100, 10 and 1 then check for scores of 1100 or 11 for success). The rest of the script composes the output page and then sends it through bin/bb to the server process. To make sure it all fits nicely together the script is defined in tasks.cfg so it is run by the xymon daemon and generates its own column on the webpages. I should imagine that you could do something similar with wsh if you're $XYMSRV is a windows box although the data directory location may be different.

Netapp Monitoring
by jamison＠newasterisk.com 02 Sep '13

Anyone using Xymon to monitor their filers? I know there's a perl client on deadcat, but I believe is uses RSH, which is a no go for me. I'm hoping there's something out there like Jeremy's rclient before I go and reinvent the wheel. Jamison Maxwell jamison at newasterisk.com<mailto:jamison at newasterisk.com>

No RRD / graph if test status is 'clear'
by Wim.Nelis＠nlr.nl 02 Sep '13

Hello, Recently I've written an external script, reporting tot Xymon 4.3.7, which measures a throughput and conditionally can perform a test. It seems that if the test status is 'clear', the data in the status message is not passed to the RRD, and thus does not appear in the graph going with this test. Is there a parameter setting to get RRD updated even if the test status is 'clear'? (The test is only possible when a specific traffic pattern is found. If the test cannot be performed, I would like to assign the status 'clear' to this test. Currently the test status is 'green' in this case, making it indistinguishable from the case "the test can be performed and the test result is successful".)

does xymon have any option to monitor a java app

Hi May I know if there's anything in XYmon which can allow a java app or maybe tomcat to be monitored? -- Cip
