Hello Everyone,
A couple of weeks ago we had a problem with the elasticsearch drive filling up on one node, which caused the dynatrace cluster to under perform and eventually go down.
We are looking into a solutions to have our own drives/cluster nodes/activegates monitored using dynatrace itself and found the local self monitoring solution, however, looking around the community and the documentation I couldn't find enough information. We have 3 main requirements and then the rest are pretty much good to have.
1. Does local self monitoring allow for monitoring of the cluster node drives (elasticsearch/casandra etc)
2. Does the local self monitoring allow for monitoring of the activegates, can I get notifications if one of the activegates goes down?
3. Can the alerts from the local self-environment be received as problems on my production environment.
Note: I am not able to switch it on yet unfortunately, since it is a customer's instance, and they would like more information before going that way.
Thank you,
Ahmed Khaled

Hello,
So the 41 metrics that I find when typing dsfm in the metrics section, are the only self-monitoring capabilities available?

Right.
Here you have the link for managed

For Cassandra and Elasticsearch healthcheck we always go to this old thread
If you want this information to show up as a metric with in dynatrace you will need to automate the running of the utilities on a cluster node, save the information to files on a directory that one of your AG can reach and build an extension that will convert the status to a metric .....
