Hello,
I have been looking to see if we can get some 'iostat' data into Xymon. However, I see that the graphs.cfg and xymonserver.cfg files already seem to be ready for an 'iostat' test. I also see that the code has a 'xymond/rrd/do_iostat.c' module.
However, I am not seeing any iostat graphs anywhere. A quick google seems to indicate that others have set up their own iostat script and run that on the client. Yet, Xymon itself looks like it is expecting iostat data, and so should be able to produce graphs.
So I'm a bit confused. If I want to monitor iostat data (I'm thinking of the wait and service times, and the percent utilised (busy)), what do I have to do to supply that data to Xymon? Do I need to modify the 'client/bin/xymonclient-linux.sh' script to include an '[iostat]' section? Or do I need to write an external script, and create my own 'iostat' test (but in that case what is the do_iostat.c code for)?
Thanks,
John.

The iostat code in Xymon hasn't really been working well. The format of the data coming in from the various iostat-implementations in the operating systems have changed over time, and Xymon just hasn't kept up with those changes.
It is something that needs to be looked at sometime ... for now, don't assume that it is working.
Sorry :-(

No problem, and thanks for the very quick reply! :-)
I'll see about setting up an external script for the clients.

What are you trying to monitor? Check here http://www.xymonton.org/monitors There is a diskstat.ksh which will graph disk IO on Solaris, and diskstat.pl was created to do the same thing for Linux. I am sure you could adapt either of those to monitor any output from the iostat command.
