while doing

docker compose up -d

signoz-otel-collector is Exited

The image you have shown here is that of the otel-migrator which has exited. This, I believe, is to be expected. Judging by the name, this will do migrations, typically between version upgrades - some assumption on my part WRT between upgrades.

when I do docker ps I can't see OTEL collector

@Harshit Paneri please understand that vauge answers won't get you help. If the otel collector existed, you should see the logs of exited container and troubleshoot what happened. If you still don't understand then post them instead of just saying it exited.

Have you tried looking at the logs to see what has caused it to stop running? Try

docker logs signoz-otel-collector

. You can confirm that it started and has stopped by running

docker ps -a

which will show all stopped / exited containers too.
