Swap on our server is set be made available at boot, however for whatever reason it is currently not available (note: this is non-impacting).
Could you let me know if this is a Dynatrace requirement not to have swap enabled? – judging by a quick Google it seems JVM based apps prefer to control memory usage, not requiring swap, so something like Dynatrace might possibly be removing it?
If this is the case, should we just prevent swap to be mounted at boot to permanently prevent or instead mount swap now if it should be used?

Hi,
take a look at our help page here: https://www.dynatrace.com/support/help/shortlink/managed-cluster-setup#step-3-run-the-installer
What happens during installation?
The installer also optimizes operating system settings:
Swap is turned off (with swapoff
).
Note that enabling swap can result in undesired behavior and so isn't supported.
