PRO TIP: Solve "High memory usage detected" in AG extensions

[AntonioSousa]

For some reason, you might see in AG/extension logs the "High memory usage detected..." entry.

These are raised when an EF2 extension uses more memory than it is supposed to consume. The limits are documented in https://docs.dynatrace.com/docs/ingest-from/extensions20/extensions-concepts#resource-consumption

If you absolutely need to, like I did with the VMware extension, the per configuration limits can be raised with the following entry in extensionsuser.conf

dslimit_python_mem=2000

In this case, each monitoring configuration might use 2000 MB

Please beware that you have to make sure that you have sufficient memory in the AG to run it smoothly...

Depending on the extension you might want to switch out the middle part of the flag to, for example, wmi or SNMP.

The easiest way to figure out which data source it is, is either by looking at the extension.yaml file or the steps when creating the monitoring configuration.

There are other configuration options that can be changed to allow more threads or change the timing interval for the VMware Extension.  Also there is an option list the dslimit_python_mem for cpu.
