Icinga2
this is very much work in progress
The overview of your nodes in Icinga2 you get at monitoring.psi.ch and there you can handle the alerts and create service windows, etc.
But the configuration as such is not done therein, but in Hiera and automatically propagated.
Basic Configuration
Enable monitoring with Icinga2 by
icinga2::enable: true
(which will be default at some point, e.g. for RHEL9).
Users and groups in aaa::admins and icinga2::web::users will have access to these nodes on monitoring.psi.ch.
Prefix the group name with a % to distinguish them from users.
By default no alerts are generated. If you wish different, set
icinga2::alerting::enable: true
Icinga2 Agent
The Icinga2 Agent can be enabled with
icinga2::agent::enable: true
Default Checks
By default we already run a comprehensive set of checks. Some of them can be fine-tuned in Hiera. Whenever you have a use case which is not covered yet, please talk to us.
Kernel Ring Buffer (dmesg)
This check alerts on critical kernel messages.
But if the message as such is OK, it can be ignored by adding a substring of it to the array icinga2::agent::check::dmesg::ignore_list in Hiera:
icinga2::agent::check::dmesg::ignore_list:
- 'SMBus base address uninitialized - upgrade BIOS or use'
