Where is neo4j.log in the official Neo4j Docker?

HI there,

I am running Neo4j Enterprise 3.5.19 in the official docker container (docker-neo4j-publish/Dockerfile at 2e3dda4f3b545c33fee51bc5fce089923a3cc1e7 · neo4j/docker-neo4j-publish · GitHub) and noticed that /logs/ only has debug.log and query.log but no neo4j.log. Is this expected?

I am trying to debug a ServiceUnavailable exception and need to see logs from the database but I didn't find anything at all in neither my debug.log nor my query.log. Based on guidance from this reply, I'm hoping to find something in neo4j.log if it exists.

My logging config is as follows:


In my container I see

{user}@{namespace-}0:/logs# ls -l
total 180
-rw-r--r--. 1 neo4j neo4j 178076 Feb 26 19:46 debug.log
-rw-r--r--. 1 neo4j neo4j    594 Feb 26 20:00 query.log


docker-neo4j/docker-entrypoint.sh at master · neo4j/docker-neo4j · GitHub you will see that neo4j is started as neo4j console and to some extent there is no neo4j.log created.

However you should be able to run

docker logs <container>

for example

$ sudo docker ps

Thanks! I didn't realize that the output from neo4j console was neo4j.log.
