This sounds extremely environmental.
I suggest a repair on the NPM installation in add/remove programs.
Reapply the latest SP
Attempt your Alert Actions again.
If these steps do not help - and you have active maintenance - please open a support ticket.
Thanks and HTH,
I installed the latest update, however it still did not work.
So I repaired the isntall and all is well.
My problem with Alert Manager is that a New or Edit command sends the CPU into hyperdrive: 100% for as long as I leave the process running. Do you expect that that could be environmental, as well? I am running NPM in eval mode; no support, yet. Don't know if I would be allowed to remove and replace with another download. Hard to rate the eval as good when I cannot configure Alerts.
I run Task Manager to see the process hung at 100%. Have tried shutting down NPM and everything except IE. System is old: XP SP2, Pentium4, 1G RAM. Actual production system will be beefier.
Even though this is an older thread - we know that lots of folks have questions about alerts, alerting, advanced alerts, alert actions, and so on. So, we did a whole SolarWinds Lab espisode on it. Join us at lab.solarwinds.com on June 12, 1pm Central for the episode. We'll review all types of alerts and alert actions. Plus, you can chat live with our Head Geeks before, during, and after the show. Whatever alerting question you have, we will be happy to address live. You can find out more and sign up for a calendar invite here.
