Alerts don't sent notifications using a webhook

Hi @dariatsvetkova21a, welcome to the community!

Are you able to receive notifications when you send a test notification from your ROCKET contact point?

I’m looking at your alert evaluation statement as well, as it’s currently configured it will do the following:

  • Evaluate the alert query result every 10 seconds
  • Fire if the alert condition stays true for 20 seconds

I’d also recommend taking a look at your panel to find out if those conditions have been met.
