I expanded my memory cluster and I want it to recognize it.

Hello, I would like to know if there is any procedure I should follow to increase the memory of my cluster, which is made up of 3 nodes. Is it enough to stop the services, install memory, and restart node by node, or is there something additional I should do? And can two nodes work with 64GB and one with 32GB?

Additionally, I have activated the F5 and SAP HANA extensions. It shows me that the connection is OK, but it does not receive metrics.

I do not have log monitoring v2 activated due to lack of resources. Is this last point related to the problem extensions?

Dynatrace recommends avoiding 2 node clusters, and keeping all cluster nodes the same specs. see this link for the actual text: https://docs.dynatrace.com/managed/shortlink/managed-requirements#multi-node-installations

I believe that process should work, but depending on if you can hot add memory, you may want to hot add it, then just restart dynatrace on each node (one at a time)

Other things to check for extensions - make sure you have the ports open, the appropriate authentication, sufficient RAM/CPU on the Active gates
