I just ran the SVN version, and everything I was testing with devmon now just remains purple. Looks like the SNMP tests aren't actually being run, I never see any SNMP oids in the devmon.log file now. I see this...

There have been some issues I could reproduce, which have been fixed in changes since 0.3.0-rc1 and 0.3.1-beta1, and between 0.3.1-beta1 and current svn. > This last time it happened, we received the following error message: > Can't use an undefined value as a HASH reference at > /usr/local/devmon/modules/dm_snmp.pm line 405, <$__ANONIO__> line 40712. > > Looked at dm_snmp.pm and we can't really make too much sense of whats going > on here. Is this helpful at all to tracking down the devmon goes purple > problem? There are some changes in svn to address some possible issues, and to add a bit more information to the 'dm' test for the devmon host (statistics for each polling process, ensuring the polling process are still communicating with the master etc., additional logging). If you are experiencing problems, it would be best if you could run the version from svn with --debug, and: -report if it works better (goes purple less often) -report on what occurs when it does go purple, there should be additional logging indicating what occurred just prior to it going purple It's probably best to do an svn checkout, see: http://sourceforge.net/projects/devmon/develop > FYI, in our older version of devemon 0.3.0-rc1, it never goes purple, so > was hoping to avoid rolling back to that version if possible. Well, you could have a look at the differences between 0.3.0-rc1 and 0.3.1- beta1, by using e.g.: svn diff -r 80:124 https://devmon.svn.sourceforge.net/svnroot/devmon/trunk/modules The only change that should have made any difference is this one: http://devmon.svn.sf.net/viewvc/devmon?view=revision&revision=82 which fixes a problem I could reproduce, and was included in the 0.3.0 (final) release.
