Too Many Notifications




We are using PRTG to monitor all of our network equipment and Virtual Servers. Everything works fine unless there is a large outage, like a power outage that lasts more than a couple of minutes. All the critical equipment is on UPS systems but there are couple hundred edge switchs that are not. When this happens we get texts for an hour or more after the out happens and after it clears. There are around 700 sensors.

We have notification summarization set to send FIRST DOWN AND FIRST UP summarize all others.

PageGate is setup to be executed and send SMS pages on sensor down and up triggers after being down for 5 minutes.

One the devices we monitor we have CPU, Traffic and Memory senors

Not only do we get Up and Down notices but "Down Ended" ones.

The trigger type we have setup is State Trigger and we inherit from local probe.

It doesn't look like the summarization is helping since it have alerts from dozens to senors, when an outage happens.

Has anyone figured out a way to stop alerts when there are more that XX numbers of downs or ups in a certain amount of time ?

I'm sorry to hear that notification summarizing does not work well in your setup. Most likely, this happens because there is too much time between the different outages, so PRTG considers them as single downs.

Have you tried dependencies? Using them you can pause monitoring of devices or entire groups when a certain sensor shows a down status. Paused sensors do not trigger notifications.

This way, you could pause your edge switches when PRTG detects an power outage.

For details about dependencies, please see https://www.paessler.com/manuals/prtg/dependencies.htm

Thanks for the information on dependences. It looks like it might work but will require a complicated setup to make sure we don't miss critical alerts. I'll keep looking into using them.

"Most likely, this happens because there is too much time between the different outages, so PRTG considers them as single downs."

Hummm how much time are we talking about, the alerts are seconds apart ? Seems like this is still the best option if there is a way to adjust the time allowed between ?

Thanks !!!
