We are using advanced alert manager to configure alerts, how to eliminate duplicate alerts to be triggered.
We are receiving multiple alerts for same server again and again.
Check your email action in the Alert Escalation tab. Make sure the option to execute and a repeated interval is not enabled. Also make sure you don't have multiple alerts set up that would trigger on the same conditions.
It is already unchecked.
Polling interval is 5 minutes, so every 5 minutes alert is trigerred and received on the email address.
We need after receiving trigger alert, it should not repeat until reset alert is received.
That's how it works by design. Once the device is in an alerted state, the alert triggers and shouldn't re-fire. Now, if there are mulitple devices that meet the condition each time it checks, it will fire off an alert for each one.
But in this case after each time polling is done alert is fired, but I need alert should not fire if it is already trigerred and not resolved yet.
Can you put in screenshots of how your alert is configured? That would be about the only way to figure out why this is happening.
What are your reset conditions?
1 st condition which means when trigger condition failes
So you have the alert to trigger, then start a 15 minute countdown before the alert actually becomes an alert, it's basically in a stand-by mode for 15 minutes. Within that 15 minutes, if the system falls out of the 90% it's going to reset the alert, then again, the next time it polls, if it goes back above 90, it starts the 15 minute countdown. If you don't need the 15 minute timer, I'd remove that. Unless the CPU is continously spiking up and down, it shouldn't retrigger the alert. The other areas I'd look at are:
