Problems with alerts after conversion to web based alert manager

Hello,

We recently upgraded our Solarwinds NPM and upgraded the alerts to the new web based manager.

Since we did this one of our alerts is acting weird.

We have an alert that emails us when a nodes receive or transmit bandwidth reaches 90%

The alert still works fine for the trigger condition of 90%

However since upgrading this alert now triggers randomly even though the trigger condition hasn't been met and so we receive emails for nodes at 0% or 17% utilisation.

Has anyone else had this problem?

Thanks

Luke
