We have set up Alerts and End to End monitoring configurations according to instructions but still can't the alerts to trigger. While trying to see the process reciew in End to End monitoring, we get a Java Null Pointer Exception pop up with an option of "Start JNET" or "Stop". Is this attributed to the alerts not being triggered?? We are in SP11. So we are heavily dependent on the END TO END monitoring config. What could be the issue?
