All services from hosts with the metric backend enabled were named with the prefix "OTel metric", for example "OTel metric cpu.load".
To make service names shorter and less redundant, the fixed prefix has been shortened to "Metric". The same service is now named "Metric cpu.load". The discovered metric name itself is unchanged; only the fixed prefix text changes.
After applying this werk and rediscovering services, the old "OTel metric X" services vanish and new "Metric X" services are discovered. There is no connection between the old and new services, so:
- Historical performance data tied to the old service name ("OTel metric X") is not carried over to the new service name and is effectively lost.
- Any rules, downtimes, notifications or other configuration referencing the old service name "OTel metric X" will no longer match and must be reconfigured against the new service name "Metric X".
Rediscover the affected hosts to pick up the renamed services.
