Where is rocketchat's log file?

Description

Install rocket chat on a private cloud VM with:
Ubuntu 16.04
40GB Disk
after 2 month running, VM’s disk is full, tried to extend disk,
I did resize volume but can’t extend the partition because no disk space remain to install other package to resize disk partition
So, where is rocketchat’s log file? Where I could temporary delete some to get disk space?
Regards, LongNX.

This is a popular post but the answer to the original post won’t be to delete logs.

Where do *buntu servers store logs:

You can also use some of these commands in a terminal:

journactl

journalctl -u snapd

journalctl -u nginx.service

journalctl -f

journalctl --disk-usage

journalctl -xe

More information on snaps specifically here:

For docker logs you can use something like:

docker logs -f <container_name>

As for this particular issue logs don’t usually take up that much space, relatively.

It is most likely that the MongoDB inside the snap was using GridFS and got filled with files.

First thing is can you delete any other files to make space?

If not then follow the above FAQ, stop Rocket.Chat, backup, remove the snap, increase the disk size, and restore.

Make sure you restore to the exact same version you backed up from.

There may be other answers but hope this helps people searching for log questions.

Hi, I’m back here again, 4 months ago, I can’t figure out how to delete file, and my data is quite small, so I erase everything and start over with a 100GB disk and config to Rocket to auto delete file & message every 3 months, but now it failed again,
can you give me a guide to delete my users’ files in the MongoDB?
