You can filter Snaplex node metrics so that the collector only reports on a subset. Refer to Node metric reference for a list of all node metrics.

1. Open the otel/config.yaml file.
2. In the processors element, add the following:

   processors:
     filter:
       metrics:
         include:
           match_type: regexp
           metric_names: <plexnode.name>

   For example, to include CPU, memory, and disk metrics:

   processors:
     filter:
       metrics:
         include:
           match_type: regexp
           metric_names:
             - plexnode_cpu.*
             - plexnode.mem.*
             - plexnode.disk.*                  

3. Add filter to the service > metrics > processors element:

   service:
     pipelines:
       metrics:
         receivers: [otlp]
         processors: [batch,attributes,filter] # added filter
         exporters: [otlphttp, logging]

4. Copy the config.yaml file to all nodes.
5. On each node:
   1. Run docker ps to get the OTEL container ID.
   2. Restart the OTEL service: docker restart <container-id>

The OTEL collector will only report on the specified metrics.
