Re: alarm handler

[Ralph Lange <ralph.lange@gmx.de>]

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
