Default service response time alerting

g_kat — Wed, 25 Sep 2024 08:32:53 GMT

Hi,

This maybe a rudimentary question but I wanted to be completely sure:

Let's say we have a Web Request Service that has X service methods/endpoints. I leave the anomaly detection for response time on default values. Will Dynatrace raise an alert whenever 1 of those service methods deviates from the default baseline, or it will wait until all service methods deviate from the baseline?

I think is the former, but I think I read somewhere about a corner case(if an endpoint contributes less than 1% to the load is ignored, or something along those lines).

Thanks,

George

Hi,

You can check/change anomaly detection for services. It will affect all request in relation to that service.

If you want different threshold for a single request, you need to mark it as key request, in advance. Then, you can Request-specific alerting thresholds.

Best regards

Hi Anton,

I don't want a different threshold, quite the opposite I want all requests to obey the overall threshold. But, I want to be sure that it will raise a problem for the service if even 1 endpoint is problematic.

Key requests are definitely a solution, but I wanted to double check whether I need them, since if by default Dynatrace alerts on endpoint deviation I don't have a need for them.

Thanks,

George

Hi,

One of benefits of key request is "Alerting is always enabled for key requests, even when they contribute less than 1% of throughput".

If response time is higher than normal, it would raise a problem, no matter throughput.
