We are installing dynatrace appmon 7 (linux). It's all right. However, a message in the collectors insists on appearing: "xxxx-xx -xx: xx: xx WARNING [ClusterTimeProvider] Exception synchronization cluster time: COMMUNICATION_ERROR [log message will be suppressed for 1 hour]".
Our suspicion was something related to ntpdate, however everything is ok.
Does anyone know anything about this error?
Thanks in advance.
Solved! Go to Solution.
I was able to find a support ticket where users were experiencing a similar issue to yours and here is the description of the issue and how to resolve it:
"The message you mentioned, means that most probably the port 8041 not being opened. In general this is as follows:
This warning indicates that the collector component that is responsible for oneAgent(NodeJS agents for example) management is unable to synchronize it's internal timer with the dynatrace server. This is often caused by the relevant ports being closed by the firewall. If you don't have any NodeJS agents(or beta OneAgents), then this warning has no effect on your environment.
There're 2 ways which can remove this warning for good:
Hope that helps,
Yes, it should work, actually, that was where the person in the support ticket experienced this issue (6.5 environment).
