Sampling interval (observed plot points) for APM sourced metrics vs. SVM sourced metrics.

Blaine_Johnson — Fri, 28 May 2021 14:54:28 GMT

We've noticed we are not getting the 1 minute sampling interval for the metrics that are sourced by the Server Visibility Monitoring agent. Documents confirm and we do see 1 minute for the metrics sourced from the APM agent for up to 8 days. Is there a way to get sampling to a shorter interval (currently experiencing 5 minutes) for the metrics from the SVM agent?

Thank you.

Hi Blain

You can set the smapling frequency lower by changing the sampling frequency in the ServerMonitoring.yml file.

https://docs.appdynamics.com/21.5/en/infrastructure-visibility/server-visibility/machine-agent-settings-for-server-visibility

Not sure if you can make it less than 1minute, or let me say it this way the backend controller will only store a certain amount of samples per minute.

If I can remember correctly it will store 1 metric per minute, so for your use case that should be fine. If you want to reduce the sampling to less than 1 minute you would have to check with AppDynamics what the Controller backend will support

Hi Mario,

Thank you! It looks straight forward enough. I have verified the setting in the config.yml file and I sent it to the application developer to consider. I'll let you know how it comes out.

Thanks,
