hi everybody,

i need to have a real correlation "motor" in Nagios Core.

The rules in Nagios are insufficient.

for example, i want to :

* when a router is down, i don't want to receive alerts from all hosts
* i want to be able to run script on alert
* i want to be able to modify some old events and resend them or others in the correlation's motor
* what about the console ?
etc......

So, if i want to write complex rules, can i plug NagiosLogAnalyzer and do correlation with NagiosLogAnalyzer fromevents coming from logs and from events coming from Nagios.
Is it possible ?
and how ?

Best regards
T Granier

A few suggestions from your list.

You can limit the alerts when a host is unreachable in nagios.cfg.
Look into event handlers.
I'm not sure what the other two mean. The same with, "etc."

I don't know what NagiosLogAnalyzer is. There is Nagios Log Server, which can send log events to nagios that create alerts.
