I am collecting Docker container logs using OpenTelemetry Collector and exporting them to Velodb, viewing them in Grafana.

The issue is:
Stdout logs are visible in Grafana, but I cannot filter them by service_name or container_id.
The only way to find stdout logs is by searching text in the log body.

Method 1- filelog recevier

I used the filelog receiver to tail Docker json-file logs from:
/var/lib/docker/containers//-json.log

Collector config:

receivers:
 filelog:
    include:
        - /var/lib/docker/containers/*/*-json.log
   start_at: beginning

stdout logs are visible in grafana but cannot be filtered by container_id or service_name.

Method 2 - fluentbit -> fluentforward

Fluentbit config:

[INPUT]
    Name   tail
    Path   /var/lib/docker/containers/*/*-json.log
    Tag    docker.*

[OUTPUT]
    Name   forward
    Match  *
    Host   opentelemetry-collector
    Port   24225

Collector config:

receivers:
      fluentforward:
            endpoint: 0.0.0.0:24225 

again stdout logs are visible but cannot be filtered by container_id or service_name.

I want stdout logs to be filterable per container (either by container_id or mapped to service.name), similar to how container logs are separated in CloudWatch.
Any suggestions, if possible any working example will be helpful .
