In order to test if your IDS is receiving alarms, you need to generate false alarms, for eg; you can configure CSPM that if someone pings i.e. 'icmp-echo' request, you should see a Level 5 alarm.
Modify the signature database on CSPM for the echo-request signature to Level 5 and then push the config to sensor. Then do a ping test and check the Event Viewer if you see Level 5 alarms.
