Solman Technical Monitoring alert not triggered

Hi guys,

I'm currently configuring Technical Monitoring in Solman (version 7.1 SP12). I've created a custom template using the Oracle template and enabled the metric 'Oracle Database Status' such that I get an email notification whenever the database goes down:

To do a test, I shutdown the database and waited for quite some time but I didn't receive the mail.

What frequency does the hostagent checks for the database status? Is there anything I missed in the configurations?

regards,

Suraj
