I just set up a Dynatrace Managed cluster (1.196) at a customer and while I was not watching they connected VMWare monitoring without setting up any ActiveGate first.
I guess that VMWare monitoring runs on the internal Cluster AG now.
While this is a nice improvement from the hardware requirement side it doesn't fit the documentation and might cause problems in more restricted networking szenarios. Can someone from Dynatrace please comment on this? Is this a glitch or a new feature?
Solved! Go to Solution.
With Dynatrace Managed this was never required, it always was connected via the embedded ActiveGate on the Cluster node. If you install Environment ActiveGate in Dynatrace Managed, it will be used for the connection.
ActiveGate was and still is is required for SaaS environments to connect to VMWare.
Install an Environment ActiveGate in your data center before connecting Dynatrace to your VMware platform.
For Dynatrace Managed you can use the embedded ActiveGate running on the cluster node. However, the Cluster ActiveGate is typically used to forward RUM and/or Synthetic monitoring data to the Dynatrace Cluster. We recommend that you don't overutilize this ActiveGate with another type of monitoring data. Depending on the VMware size, you might consider using a dedicated ActiveGate per environment.
Embedded = installed on cluster node.
Hard to tell what it is too big - all environments are different, more dynamic in creating/re-creating instances, disks, metrics etc. observe AG CPU and memory utilization.
Well that doesn't really answer the question. Either it's automatically done - if I set up an environment active gate, the embedded won't be used anymore.
or - meanwhile I searched the installation folders of the managed cluster - the is a custom.properties inside <dynatrace install folder>/security-Gateway/config/. It's just not documented anywhere...
True, but that's intentional. In that case, you shouldn't need to change that configuration at all as environment AG should take care monitoring, right?
Well, I would not recommend touching embedded ActiveGate configuration, unless it's necessary. The files are there, just in different locations.
If you need for any reasons to adjust something, I'd recommend to install either a Cluster ActiveGate or an Environment ActiveGate and make those modifications.
