I'm new to SolarWinds and just setting up alerts for the first time. One of the alerts I configured was to check for low disk space:
Trigger Condition (when all apply):
Volume Type is equal to Fixed Disk
Volume Percentage Used is greater than 95
Volume Percent Used is not equal to -2
Caption is not equal to Physical Memory
Caption is not equal to Virtual Memory
Reset condition is default - when no longer true
Nothing under Alert Supression or Reset Actions
The trigger action is to send an email.
It appears that when I do a Test Fire Alert sometimes it works (I receive email reports, and sometimes I do not even though some of the nodes certainly meet the conditions). Also when you do a test, I don't understand the purpose of selecting a network node. Is it really only checking single node? Because even though I select one, I'll either get a flurry of 15-20 emails (all the volume that match the conditions), or zero.
After I ran the test, I never receive another alert even though I have taken no action to clear up disk space (the trigger conditions are still met). I have Alert Evaluation Frequency set to every 30 minutes (general tab), and Execute this action repeatedly every 5 minutes while the alert is triggered set (email - alert escalation tab). I'd like to have the reports keep coming until the condition is cleared. Please advise.
