Is it possible to send an alert when the polling engine is down. Specifically, I'd like to send an alert that the polling engine is down. Is this possible or do I need a 2nd polling engine to monitor the first?
Anyone?
I use a perl script, running on a different server, to pull polling engine status from the web interface. Might also be something in database that changes on regular basis when NPM is running properly. In any case, if you are concerned about making sure NPM is running, do it from another server, otherwise you miss the event.
There are a couple of options:
1. If you have the Hot Standby Engine, this has an inbuilt alert option to send an email when the Hot Standby Engine has to take over polling for a server. This is configured in the 'Monitor Polling Engines' console application
2. Use each of the polling servers to monitor each other. With the Orion NPM core application, this would be on the server response, whereas with the APM module you can be far more specific; Are the services running or performing a DB query to look for DB writes from the polling engines (a count with a time filter) etc.
Hope this helps
