Search before asking

• I had searched in the issues and found no similar issues.

Apache SkyWalking Component

OAP server (apache/skywalking)

What happened

In clustered mode, when data is received and deserialized in RemoteServiceHandler, MetricsMetaInfo in AcceptableValue is always initialized (metricsName="UNKONWN",scope=0). As a result, such data cannot trigger alarms in cluster mode

What you expected to happen

I expect that the metrics monitored by the infrastructure in cluster mode can normally trigger alarms

How to reproduce

Replication mode: Access infrastructure monitoring data in cluster mode and add alarms to the data

Anything else

The alerting is only based on metrics persistent. If something wrong happened in the RemoteServiceHandler, then the metrics in the database are wrong too.
I can't follow up your description.

By this I mean that the MetricsMetaInfo in Meter obtained under RemoteServiceHandler is (metricsName="UNKONWN",scope=0), resulting in no alarm being triggered when the notify method in NotifyHandler is executed.

We confirmed this and addressed the root cause. #13543 will try to fix it.
