Hi All ,

We are monitoring NetApp filer for its disk space usage on mounted volumes . We are facing a weird issue where event generation is not happening as configured. Below are the configured info .

Threshold :

1: Warning alert for 90% usage .

2: CRITICAL alert for 95% usage.

Triggers and Notification :

1: Production state - Production

2: Trigger is set to run when in new status .

Disk space usage :

1: Volume  usage vol1:94%

2: Volume  usage vol2:91%

3: Volume usage vol3:92%

4: Volume Usage vol4:96%

Issue :

For volumes 1 and 3 , we are getting WARINING alert where as for 2 and 4 we see no alert event when the usage is above the threshold . I am worried on why such a weird behavior when all these filers are of same type. Zenoss is able to read the usage value but not generating the events as configured .From the logs  i see that triggers are running successfully
