Hi Rolf,

There are several different implementations of CA plug-ins for Nagios/Icinga, a common open source tool for monitoring IT infrastructure. Some are so-called "active checks" (run by the Icinga server) doing CA get operations, others are stand-alone servers monitoring CA PVs and feeding the updates into the Icinga server ("passive checks"). The EPICS alarm levels map nicely onto the Nagios/Icinga severities. The Nagios/Icinga ecosystem has a large number of plugins and interfaces offering a wide range of functionality.

For data mining, you can feed the Nagios/Icinga logs into a big data log database, e.g. Splunk, which offers very powerful offline analysis. (Especially if it also gets the logs from IOC consoles, servers and network devices.)

Pointers:
For Nagios/Icinga, Legnaro Labs and BESSY II use the active checks, APS uses a monitoring daemon (passive checks).
Splunk is used at a couple of facilities, including NSLS-II and BESSY II.
I also remember ICALEPCS and EPICS Meeting posters/talks about these things.

Cheers,
~Ralph

I would be interested to know if anyone in the non-Control-System-Studio world uses/has an alarm handler other than the motif-based alh.

Thanks - rolf -
