ActiveGate Offline (Managed)

Pedroka — Wed, 28 Aug 2024 06:23:48 GMT

My Cluster activeGate is offline, i've already rebooted the VM and restarted the activeGate, but still don't work

Can anyone help me?

A couple of things that come to mind:

Are the AG process running
- systemctl status dynatracegateway
- https://docs.dynatrace.com/docs/shortlink/stop-restart-activegate
any chance of a firewall change that is blocking the connection
- (try to curl to your cluster API from AG)
SSL cert or token expired?
Anything in the logs?

also, Id probably recommend fixing the cluster issue you asked about before this one.

1. AG process still running

2. About SSL cert or token, and connection... Dynatrace says: There is no Cluster ActiveGate installed. This setting will be disabled.

But i didn't uninstalled it, this is what i don't understand.

check the minimum requirements are met or not against the installed cluster AG.
If there is a load balancer between ActiveGate and the next communication endpoint that traffic should be routed through, configure seedServerUrl and ignoreClusterRuntimeInfo
If a proxy is used to reach the Dynatrace Cluster or any of the monitored clouds, configure a proxy.
If not configured, ask firewall team configuring AG Headers.
