Are there any metrics than can be charted to view stats regarding a Dynatrace Managed Cluster? e.g. Health of your nodes, active gates (memory, disk), number of DEM units left etc. so that it can all be viewed on one dashboard for our monitoring team
Currently there is no API for those metrics. The only way is to relay on Dynatrace Misson Control to get proactive alerts if something goes wrong with the cluster.
I would be very interested in options to get more data about the dynatrace managed cluster health as well.
I would not recommend that. A self Monitoring Agent is already running on managed cluster nodes to report data to mission control.
If you overwrite it with another OneAgent and send the data to one of you environments, Mission Control will no longer get that data.
