ActiveGate Offline (Managed)

[Pedroka]

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:

1. Are the AG process running

   • systemctl status dynatracegateway

   • https://docs.dynatrace.com/docs/shortlink/stop-restart-activegate
2.  any chance of a firewall change that is blocking the connection
   • (try to curl to your cluster API from AG)
3. SSL cert or token expired?
4. Anything in the logs?
   • https://docs.dynatrace.com/docs/shortlink/activegate-diagnostics

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.

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

Ok, thanks..

Hi @Pedroka 

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

During validation:

1. stop AG Service.
2. configure the missing parameters within custom.properties file.
3. save the changes.
4. restart AG Service.
