Hello Eslam,

you can use duration parameters as following, knowing that Dynatrace get the sample every 1 minute for most of metrics:

Violating samples : Number of times that the threshold is violated.
Sliding window : The duration that you will consider the violating samples in.
Dealerting samples : how many time needed below threshold to close the problem.

Please let me know if you need further clarification.

Thanks,

Islam

Hi Islam

Thanks for you replay

so based on what you mentioned
i have to devide the 100 request / 60 min to get the right value to use in Violating samples

and at the Sliding window i will put 60 as a min

and at the Dealerting samples i will bet the normal expected requests to consider it normal per min

if you can give me number for examples it will be great as i want to consider it problem if the number of requests reach 100 per hour

You can do it as below:

Threshold : 100

Violating samples : 5
Sliding window : 60
Dealerting samples : 5

Hi Isam - one more help.

Below is enviroment level settings for violating samples(for 10 seconds sample)

Violating Sample - 90, Evaluation Window - 90 , Dealerting samples-90 , Evaluation window size for dealerting samples - 30

How do i set the above in the metric event as it is 1 min sample used
