events correlation

hi everybody,

first, i have installed Nagios Core but i don't find an adequate forum

i need to have a real correlation "motor" .

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

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

Hello @wolfgang,

You CAN actually make it so that you only receive one alert when your router is down instead of everything. By setting parent/child relationships, if a parent host goes down, the child nodes will not have notifications sent.

You CAN have a script run on alert with the event handlers system.

I'm not sure what you mean by
i want to be able to modify some old events and resend them or others in the correlation's motor
. Can you elaborate?
