Let us know if this is still an issue or how you resolve it.
Your question is still vague; what is it you're trying to accomplish? Sending an event to Nagios? Why not just sent a SNMP trap?
Is there a way to send alerts to Nagios from APM? is there already a script that we could leverage.
Per Hiko_Davis's comment above you can use the APM SNMP trap functionality and publish a MIB for import into Nagios.
Here is the 10.1 wiki section: Configuring the SNMP Adapter - CA Application Performance Management - 10.1 - CA Technologies Documentation
Also some knowledge documents can be found from this search: CA Application Performance Management - CA Technologies
Hope this helps
Please let us know if there are still outstanding questions after reading the above responses
As Oscar mentioned in his comments "i dont like to create a service in nagios against every alert we must check .... i think it is difficult to maintain."
As there is an individual service name required for each alerts that APM will trigger to Nagios. It would be difficult to maintain it. If you could let us know if you guys have an integration with Nagios that would overcome this issue. Or is there any way in which APM can send alerts to Nagios without having a separate service name for each APM alerts.
Let me know if you need detailing.
