Hi, I'm doing a test installation for implementing a new monitoring tool for this company. What i'm trying todo is configuring the CPU Load Sensor with the condition: If the cpu load of the machine is higher then 90% for 5 min it should trigger an alarm. I cant find how to do this. What i've found is to configure a notification (state trigger), but then i'm only able to send an notification (email or ticket) but we want to have an alarm only if the CPU is 90% for lets say 5min. Is this even possible?

Using limits, you can set the sensor to a Warning state when the load is over 90%

Next, add a state trigger, and set: 

When sensor state is Warning for at least xx seconds perform ....

Thank you for the reply!

do you mean to set a notification state trigger?

there i dont have the option to set the senor to a down state

only options i do have is:

..... seconds perform: NO Notification Email and push notification to admin Email to all members of group PRTG User Group Ticket Notification

maybe my question wasnt clear but i want the state of the sensor to be down

First you need to set limits to set the sensor to Warning or Down when the load goes over 90%

Using a state trigger you can define what has to be done when the sensor enters a new state (Warning or Down). Here you can, for example, send an email when the sensor is down for more then 300 seconds.

I have setup a warning when the sensor reach the limit of 90% and i also have setup the state trigger but this doesnt solve my problem. I want the sensor to be in a error state (not an email), only when it stays above 90% for 300 seconds.

I don't think that can be done 'out of the box', this might require writing a Custom Sensor.

You can set the sensor to error (so it will go red and alarm), but for CPU sensors I don't set state triggers, I use threshold triggers. So if the CPU load channel goes over a set % for at least a set time, it triggers an SMS alert to key team members.
