And what are ther permissions of the parent folder, `apmuser`? Logstash would need permissions on this folder as well.

User folders have permissions only for the user, you would need to change the permissions of the `/home/apmuser` folder.

But I would not recommend this, using another user folder for logstash tmp path, you should create a new path like `/opt/logstash_tmp`, give permissions to the `logstash` user and use this path as the tmp path.
