Log Monitoring Connection Error in Signoz

Hi Signoz team,

We are looking to add log monitoring to our product and following this doc----->https://signoz.io/docs/userguide/collect_logs_from_file/

In our case signoz is running on a different host.
But after mounting our logs file, we are getting this error in out docker logs---->

 Err: connection error: desc = "transport: Error while dialing dial tcp: address tcp/8080/: unknown port"     {"grpc_log": true}
2023-03-16T08:48:25.681Z        info    fileconsumer/file.go:178        Started watching file   {"kind": "receiver", "name": "filelog", "pipeline": "logs", "component": "fileconsumer", "path": "/home/ubuntu/.pm2/logs/DISHA-PROD-out.log"}

Would really appreciate some help with this.

I can see there are two errors
1. There is some connection error.
2. There is a parsing error in json_parser
can you share your config file and some sample logs which you are parsing using that config file.

God rid of the parsing error but still facing connection error.

led to connect to {
  "Addr": "localhost:8080/",
  "ServerName": "localhost:8080/",
  "Attributes": null,
  "BalancerAttributes": null,
  "Type": 0,
  "Metadata": null
}. Err: connection error: desc = "transport: Error while dialing dial tcp: address tcp/8080/: unknown port"     {"grpc_log": true}

Did anyone come across this before?

please share your config it will help me understand what you are trying to do.

nitya-signoz Sure.

Path----->/signoz/deploy/docker/clickhouse-setup.



Our log file is at this path----->/home/ubuntu/.pm2/logs/DISHA-PROD-out.log


We are using this command to mount it ----->

docker run -d --name signoz-host-otel-collector --user root -v /home/ubuntu/.pm2/logs/DISHA-PROD-out.log:/home/ubuntu/.pm2/logs/DISHA-PROD-out.log:ro -v $(pwd)/otel-collector-config.yaml:/etc/otel/config.yaml signoz/signoz-otel-collector:0.55.0-rc.3

the otlp exporter port is not correct, it should be 4317
