Hello. I am using Observium to monitor two postfix servers. However the APPS summary site, does not show the postfix graph. From what i can gather it seems that there is a mismatch in what application name the apps overview page uses and the apps subpage for the individual server. i.e. the postfix server app subpage calls http://observium.my.server.bla/graphs/to=1465199547/id=10/type=applicat ion_postfix_sent/from=1465113147/ and the apps overview calls: http://observium.monitor.srv.aau.dk/graphs/to=1465199603/from=146511320 3/legend=no/type=application_postfix_mailgraph_sent/id=10/ if i remove the "mailgraph" part form the last link the correct graph shows. I've tried to add the postfix application to the "includes/definitions/apps.inc.php with no luck. If the application name is correct it cannot find the graph postfix_sent etc.

<?php // Definitions related to the applications system // Application graph definitions $config['app']['moodle']['top']            = array('users', 'mobile'); $config['app']['varnish']['top']        = array('backend', 'cache', 'lru'); $config['app']['postfix_mailgraph']['top']      = array('sent', 'spam', 'reject'); // End application definitions

I might be overlooking something or doing it wrong, but it seems that the mismatch should be corrected? I have added both postfix scripts form scripts/agent-local

And a second question. I've made a custom Observium app for monitoring an application, which is working fine. My problem is that i wish to extend the agent to monitor some extra paramters. RRDtool now says that there is no entry for the new DS in the rrd file. Is there a way to update the RRD file, so i do not have to delete it and loose the historical data from the other parts that i monitor?

Let me know if you need additional informations on both problems.

Best Regards, Mads.
