I would like to setup an alert that will send an email only if the amount of nodes down is greater than 3. When the number of nodes above 3 come back up an alert will be sent to say these nodes are back up. Is this possible to setup?
I have never done it but theoretically I think it is possible using SNMP traps. If you configured an alert to send an SNMP trap to the solarwinds server you could then write an alert in the Traps Viewer that said if the number of traps recieved is 3 or greater trigger the alert.
You would have basically two alerts written to accomplish this but I think it could be done in this fashion.
