You can provide a conf file for this plugin along with the test instructions as a comment to this RFE. Thanks, Leonid. I don't know, why it was moved from on_qa to post, but the fixed-in version is still correct (or any later version). Seems that plugin reports about events that it should not. The conf files I have used is: ---------------------------------------- LoadPlugin procevent <Plugin "procevent"> BufferLength 100 RegexProcess "/^.*nova.*$/" RegexProcess "/^.*neutron.*$/" </Plugin> ---------------------------------------- I have the following logs in the collectd.log fie: [2019-07-22 09:21:21] Notification: severity = OKAY, host = controller-0.localdomain, plugin = procevent,

It looks like you're using the old format, "RegexProcess". I don't know where the source link is for the code you're using, but it should be documented just like the following: https://github.com/abays/collectd/blob/procevent/src/collectd.conf.pod#plugin-procevent My apologies on the confusion. This plugin and the other two (connectivity and sysevent) have undergone significant refactoring since that document was written. I will circle back and update it. I'm not sure what the Collectd standard is for bogus configuration parameter names. Technically this could happen with any plugin. It seems like the default behavior is just to ignore invalid names. Those are just warnings that those PIDs, which were served to procevent via netlink, did not have an associated comm file. Procevent needs to read the comm file to know what the name of the associated process is. So those aren't a problem in and of themselves. If, however, those were the PIDs for the "nova" and "neutron" processes you were trying to monitor, then it's an issue. Even still, it's not something over which procevent has any control. If the netlink socket says there was a PID event, yet there's no comm file for that PID on the file system, there is no action the plugin can take other than to report the discrepancy. collectd.log:[2019-08-07 00:03:11] Notification: severity = OKAY, host = controller-0.localdomain, plugin = procevent, plugin_instance = nova-manage, type = gauge, type_instance = process_status collectd.log:[2019-08-07 00:03:15] Notification: severity = FAILURE, host = controller-0.localdomain, plugin = procevent, plugin_instance = nova-manage, type = gauge, type_instance = process_status collectd.log.1:[2019-08-06 00:30:39] Notification: severity = OKAY, host = controller-0.localdomain, plugin = procevent, plugin_instance = nova-manage, type = gauge, type_instance = process_status collectd.log.1:[2019-08-06 00:30:43] Notification: severity = FAILURE, host = controller-0.localdomain, plugin = procevent, plugin_instance = nova-manage, type = gauge, type_instance = process_status Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
