How to disable cluster heartbeat logging in Akka.NET

Question

When trying to troubleshoot a cluster setup in Akka.NET the cluster heartbeat messages are filling up the log.

[DEBUG][8/9/2016 6:04:32 PM][Thread 0011][[akka://mysystem/system/cluster/core/daemon#1680718572]] [Initialized] Received Akka.Cluster.GossipStatus

Is there a way to prevent this log event selectively as there appears to be possible with Akka for JVM?

Answer 1

I faced the same issue. There were too many gossip messages in the log and I wanted to prevent this.

Here is a solution.

https://github.com/akkadotnet/akka.net/blob/v1.1.2/src/core/Akka.Cluster/Configuration/Cluster.conf#L77

So to avoid polluting the log with GossipStatus messages like this one (similar to your example):

[DEBUG][2016-12-26 1:48:36 PM][Thread 0004][[akka://mysystem/system/cluster/core/daemon#1458732427]] [Initialized] Received Akka.Cluster.GossipStatus

You just need to set the following option off:

cluster {
    log-info = off
}

Meantime if you have remote option turned on like this:

remote {
    log-received-messages = on
}

Then you will still have some cluster gossip messages logged (as @Aaronontheweb mentioned), but these messages are different. Compare for example with this:
