The rocketchat_apps_logs.bson collection is huge, can we reduce or remove it?

[robw]

Oh, the problem is not gone.

I'm not sure when that happened, Rocket.Chat had stopped working again this morning when I logged in so that's when I checked. So I assume it's Rocket.Chat again. Since the app wasn't working the logs are full of errors, so I couldn't easily see anything useful there. Since the Rocket.Chat container's file system changed in the last update, I can't seem to see the .bson files any more so I can't confirm that was the problem and I'm not sure what else to check.

There were some other automatic app updates over the last two nights (though not Rocket.Chat because it's up to date), so I suppose it's possibly not Rocket.Chat this time, I'm just assuming.

I can't see that data anywhere on the Cloudron disk from the server console. A du -h --max-depth=1 at the root level on the server shows Cloudron is using in expected the amount of space taken up by the apps in the coloured parts of the bar above even though df says the disk is full. The 'everything else' data doesn't seem to exist. So I can't tell what the data is. It appears to be living in the overlay filesystem until a Cloudron reboot, at which time it disappears. (Sorry I didn't take a screenshot.) I know nothing of these virtual file systems, so apologies if I'm explaining that wrong, just reporting what I can see.

So after a reboot it's all good again. After 30 minutes or so, there's no evidence so far that the disk is filling up or anything is changing on the disk yet:

@robw Maybe the data is somewhere in the rocket.chat container. you have to open a web terminal and inspect the /run and /tmp of the app . Another location might be inside the mongodb container. For this, docker exec -ti mongodb /bin/bash and inspect there. As you found, volume data in docker can be hard to get to the bottom of.

I have the same "filling up space" problem on two cloudrons I administer. They are not working, as space is totally filled up. Is there a fix? What can be done?

[girish]

Did you change the log destination to filesystem? Did you try the mongodb commands suggestered earlier?

[stoccafisso]

@girish I have cloudron version 8.2.3, but can't find any "apps" konfiguration under "Settings". Where do I find the settings to change the log destination?

[girish]

@stoccafisso the issue is not related to Cloudron. It seems rocket.chat is filling up the logs (specifically, it seems apps inside rocket.chat are putting lots of logs). See https://forum.cloudron.io/post/100242 for the setting, it's inside rocket.chat

[stoccafisso]

@girish thanks a lot for helping.

I have had some frustrating hours, had to reinstall the whole cloudron in a 16GB ram droplet in order to be able to reinstall latest backup of Rocket.Chat, that backup was over 7GB, while only 2GB before the logtrouble startet.

Anyway, have it installed and working, and in Rocket.Chat made the exact setting you advice above. But in the Rocket.Chat terminal /app/data I can see no "app_logs" file?

Also when I go into mongodb and issue the commands you suggest, I get the following error message:

root@1116b395-909e-4f51-bd9e-9ad9bed3846e:/app/data# mongosh -u "${CLOUDRON_MONGODB_USERNAME}" -p "${CLOUDRON_MONGODB_PASSWORD}" ${CLOUDRON_MONGODB_HOST}:${CLOUDRON_MONGODB_PORT}/${CLOUDRON_MONGODB_DATABASE} db.getCollection('rocketchat_apps_logs').countDocuments()
bash: syntax error near unexpected token `('

I would like to have a look in mongodb, and delete logentries there if there are any. So what to do with these two issues?

[stoccafisso]

Sorry, I forgot to create the directory and make cloudron the owner. Done

[robw]

@stoccafisso I can confirm that for me this is Rocket.Chat flakiness, not Cloudron. I fear your restoration process won't help if Rocket.Chat is just going to kick off its log filling process again.

@girish I haven't yet tried moving logs to the filesystem, because (very strangely) my Rocket.Chat settings page currently appears to be empty, just a search box:

That's a Rocket.Chat mystery I haven't figured out yet.

I did try the scheduled mongodb log clearing idea directly in the app container, but it didn't seem to help. Because I can't see what's actually happening in the database, I don't know if that's because the data is filling up faster than the query runs, or because of database locking because the database is so big (100s of Gb), or something to do with virtual container file system strangeness, or something else.

At this stage my server seems to have fallen into this pattern:

• Rocket.Chat fills the disk
• Rocket.Chat attempts an update (I have auto updates on)
• Update fails because the backup fails (no disk space to prepare the backup, even though my backups go offsite to Backblaze)
• Rocket.Chat restarts, at which point the "filled" disk space moves from within the Rocket.Chat container to the virtual file system (reported as "everything else" on the Cloudron System Info page)
• A reboot releases the disk space from the virtual file system
• Start over...

The disk filling doesn't seem to start immediately any more. I don't know what triggers it.

So that means with a reboot every day or so, the server is more or less operational for general usage, except for a while right at the end when the disk is full.

I'm hoping a Rocket.Chat update will arrive soon that makes this go away.

[robw]

Quick update: We now have Rocket.Chat on the 2.54.3 package (ran a manual update without a backup), i.e. the small update which sets the Deno cache directory. It has not fixed the problem. Nothing useful from the Rocket.Chat forums yet. So still working on it.

[robw]

Quick update: Upgrade to package 2.55.0 with Rocket.Chat server 7.3.0 did not fix the problem (though I didn't think it would based on the RC release notes).

Attempts to get help on the Rocket.Chat community forum appear to have failed because I encountered the rudest and most self centred and unhelpful "Community Liaison Officer" I've ever had the misfortune to meet, a genuinely toxic individual. However, my glass is half full: the silver lining is that it reinforced my sincere appreciation of the community in this forum and the Cloudron team.

@robw a bit late to the thread but what is your current configuration for logs inside rocket.chat ? Are you using filesystem? i.e the screenshot that @girish posted at https://forum.cloudron.io/post/100242

[robw]

Good question @joseph - Unfortunately I can't see the settings in Rocket.Chat right now, my settings screen is blank. (I double checked and I do have admin user access.) So I assume it is whatever is default. A suggestion above is to change the logs storage and see what happens. I will give that a go when I get some time to work out how to alter the invisible settings.

Meanwhile, I have observed that while the disk filling process does not kick off straight away, it always kicks off when the backup process starts. Taking a backup seems to trigger the process with 100% reliability. (In fact this might be why the disk fills up overnight, as I had auto backups enabled.) Then the disk fills and the backup fails. So I have no app level backups for Rocket.Chat at the moment.

Regarding the separate problem of blank settings, I found that the Admin group had checkboxes DISABLED for all the settings configurations. I don't know what caused that or whether it's important, we've never touched this screen. I have switched these on but my settings are still blank so far.

[joseph]

@robw a "hack" is to maybe install a fresh instance and then compare what is different Will give a better idea of what you are supposed to see normally vs what you are seeing in your instance...

[robw]

Thanks @joseph - I will try that!

Meanwhile, a small update: The disk filling process appears to have magically stopped. I don't know when. So our Rocket.Chat appears to be back to normal operation. I don't see any obvious clues in the package updates, although there are updates to the apps engine, maybe it was that. Our instance is backing up and updating happily again.

It wasn't me!
