Custom RRD script
list Greg L Hubbard
Hobbit Folk, I have been struggling with the custom RRD capabilities in the latest version of Hobbit. I think I've found the issue -- if custom tests are listed in the TEST2RRD variable, then those tests are not forwarded to the test-script for action. Has anyone else noticed this? I've been through the source and can't find a reference to the TEST2RRD environment variable (but I am not much of a C programmer), so I can't verify/validate this behavior. But I have verified it by adding/subtracting my custom tests to the TEST2RRD variable and watching my debug output. Also, based on some recent mail, I think I know where to look now... Can anyone comment on this? I would really like to be able to include my custom RRD graphs on the status pages... I am using Solaris 8 on SPARC, Hobbit version is hobbit-4.1.2p1. GLH

Hmm - no, at least it shouldn't behave like that. The custom RRD setup should be very simple. If your data shows up in the "mytest" column on the Hobbit display, add the "--extra-tests=mytest" and "--extra-script=mycustomscript.sh" options to the hobbitd_rrd commandline (in hobbitlaunch.cfg), and that should be it. Your script should get called whenever there's a status update for the "mytest" column. The part that probably tricks you up is that "mytest" must be added to both the TEST2RRD setting, and the GRAPHS setting. If it's missing from either of these, Hobbit won't send it through the RRD update process. Regards, Henrik

Hmm. I am not seeing that. I have my custom tests (I am up to 4 now) in specified in the GRAPHS variable, but NOT in the TEST2RRD variable, and I am getting the values, and seeing the graphs in my Trends display. But if I put them in the TEST2RRD variable, then my custom script is never called. Which is what made me wonder -- now I am really getting confused. In (grin) in case you haven't heard it before -- congratulations on a great tool -- I think it has significant improvements over BB in every area! GLH
