Safe to truncate /home/yellowtent/platformdata/logs/* when large disk consumer?
-
I ran the
logrotate -f /etc/logrotate.confcommand as suggested, and it went from 4.1 GB (this morning) for logs to 1.7 GB, so removed around 60% of it roughly. Personally I still think 1.7 GB is a lot (I mean it's just plain text files), but much more reasonable than over 4 GB, lol.I then looked into the logrotate.conf file contents, and I see this:
<user>@my:~$ cat /etc/logrotate.conf # see "man logrotate" for details # rotate log files weekly weekly # use the syslog group by default, since this is the owning group # of /var/log/syslog. su root syslog # keep 4 weeks worth of backlogs rotate 4 # create new (empty) log files after rotating old ones create # uncomment this if you want your log files compressed #compress # packages drop log rotation information into this directory include /etc/logrotate.d # no packages own wtmp, or btmp -- we'll rotate them here /var/log/wtmp { missingok monthly create 0664 root utmp rotate 1 } /var/log/btmp { missingok monthly create 0660 root utmp rotate 1 } # system-specific logs may be configured here include /home/yellowtent/platformdata/logrotate.dI then checked the /home/yellowtent/platformdata/logrotate.d/ directory and found ones for basically each app (but only 5 apps in my case, not the 20+ I'm running... is that sign of an issue? Makes me wonder if some apps are logging indefinitely if there's no logrotate set for them...), along with platform and box, etc.
Here's an example of one of the 5 apps set in that logrotate.d directory:
<user>@my:~$ cat /home/yellowtent/platformdata/logrotate.d/3167ef7d-e4c2-4072-8e11-8de49c5db970 # Generated by apptask # keep upto 7 rotated logs. rotation triggered daily or ahead of time if size is > 1M /var/lib/docker/volumes/1db1c5dda83ebf58f62348adcc965eca2ad82585ee912ae0dabc9a06dc3f30a2/_data/*.log /var/lib/docker/volumes/1db1c5dda83ebf58f62348adcc965eca2ad82585ee912ae0dabc9a06dc3f30a2/_data/*/*.log /var/lib/docker/volumes/1db1c5dda83ebf58f62348adcc965eca2ad82585ee912ae0dabc9a06dc3f30a2/_data/*/*/*.log { rotate 7 daily compress maxsize 1M missingok delaycompress # this truncates the original log file and not the rotated one copytruncate } /home/yellowtent/platformdata/logs/3167ef7d-e4c2-4072-8e11-8de49c5db970/*.log { # only keep one rotated file, we currently do not send that over the api rotate 1 size 10M missingok # we never compress so we can simply tail the files nocompress # this truncates the original log file and not the rotated one copytruncate }The above makes it sound like there should be very little disk usage of the app logs, basically seven 1 MB files and/or one 10 MB file, right? Or have I misread that?
I guess I'm just questioning the whole logs setup... in my opinion over 4 GB is overkill for logs (4 GB of plain text is a LOT of text!), and when running logrotate it brought it to a more reasonable (but still a little high IMO) 1.7 GB in size. Then when I look at logrotate.d custom log rotates set by Cloudron, it seems to only include a few apps and most of my apps are missing from the directory which is a red flag to me... is that expected behaviour?
PS - I realize 4 GB isn't a ton of disk space in the big picture, but I am required to run my servers in Canada and we have far fewer options here, and in many cases (like OVH) the disk space offered is quite low. So 4 GB out of a 50 GB disk offered at OVH for example is basically 1/12th of the disk consumption. Of course I could use something like DigitalOcean but they charge in USD which after conversion is almost double the price of OVH for a comparable specced system, so my choices are limited unfortunately, so several GB of stuff is a larger deal for me than it admittedly may be to most, and I certainly can apreciate that maybe it seems like I'm nitpicking on the logs in that sense. Just trying to do what I can with what I have since disk space is a bit limited in Canada pricing-wise.

@d19dotca you're not wrong. I asked about this in the past and we do need much better log hygiene and settings that add up.
@staff can also reflect on how many logs they need while troubleshooting and think about a separate compressed retention setting for those who need to keep 3|6|9 months of logs.
-
I have to admin I haven't thought about how much logs to retain. It really depends on the app and the incident to determine how much longs one needs. The current settings are simply values that seemed reasonable.
@d19dotca It is not correct that only some of the apps have logrotate configs. Can you pick some missing app and then go to Location view and click save? This will re-create the logrotate config for them. BTW, is this after a full server restore? Maybe there is some bug here.
-
@girish Yeah I definitely think there's room for improvement there. Personally I think I'd set the default to be whatever you most often see being reported (or more specifically how quickly you see it being reported). I.e. do you see issues being reported from a month or two ago? Or do you see them usually being reported within hours to a week of the incident noted in the logs? I'd assume the latter, meaning we likely don't need to be keeping so many logs. And then when there's a rare issue that comes up where we need more logs, the person reporting it can simply make that quick change in the logrotate.conf file to help you guys out to debug more. That's my two cents anyways. Personally I don't think there's any use in keeping logs for more than a few days to a week in most cases.
Glad to know that there should be a folder for each app. I definitely only have 5 in there right now which isn't even close to the ~20 I have running, so I will try that out on a few and get back to you then if that helps at all.
The last time I would have restored this particular server would have been last summer sometime, so I would hope that'd have been fixed by now over time if there was a bug in there since almost every app has been updated since then too. Maybe app package updates need to also trigger that process to ensure it has a custom logrotate directory for itself?
I'll update once I've tested that more. Thanks for the help, Girish.

There's a config file for each app btw and not a folder. It will like <appid>.conf
-
@girish Okay... I think I found a possible root cause of the issue (though it shouldn't be a big deal long-term, would only impact why I saw only 5 apps yesterday)... I believe the root cause is when an app has a pending update (the green up arrow next to it) then the logrotate mysteriously disappears. Here's why I feel this way and my detailed testing and investigation here...
- I forced the logrotate again today and it somehow cleared up another large batch of space, taking it from the leftover nearly 2 GB yesterday to just under 600 MB today.

- I followed the steps suggested by @girish and that was then successful in creating the new logrotate for Radicale app, and then I ran logrotate again and it of course cleared even more space now. This lead me to see the following usage afterwards (took the Radicale log usage from 204 MB to 53 MB now):

I realized at this point that Matomo had an app update associated with it currently in my Dashboard. Yesterday when I only saw 5 apps, the vast majority of the apps at that time also had updates pending (WordPress makes up around 12-15 of my app instances, then Roundcube was one, plus Bitwarden was another, so had roughly 14-17 or so apps with pending updates at that time which I then updated last night). This makes me suspicious that possibly an app having a pending app update somehow removes it's logrotate configuration file. It kind of explains why I only saw a few apps listed yesterday, as well as why it recovered so much more disk space today when all those apps were updated last night and today their logrotates suddenly existed again. To be fair though, it doesn't explain why Radicale didn't have one today as Radicale hasn't been updated in a while and no pending app updates for it, so that's the one app that goes against my theory.
Either way... I see issues here with missing logrotate configs. And that's of course on top of the disk space concern, however I suppose if everything was running properly with logrotate my main concern may be a moot point by then. So the root cause of all of all of this may simply be missing logrotate configurations for apps.
I should add... I haven't updated Matomo yet, in case the Cloudron team wanted to connect to my server to do that update and see if logrotate suddenly exists afterwards, in case that helps at all with troubleshooting.
-
@d19dotca Thanks for the details analysis! So, after you report I decided to look into some of the Cloudrons I have access to and indeed logrotate configs for some apps are missing. Let me debug further, but there is definitely some bug.
-
I just wanted to say I noticed an excessive use of logs again on my server. I guess this wasn't fixed yet, eh?

for me,
/home/yellowtent/platformdata/logs/graphitehas more than 580 MB of logs, as well. Is that normal? -
@necrevistonnezr you can delete those files safely, of course you will lose all logs history, but if you don't have any immediate issue on your server besides log size, you can just remove them via ssh.

The logs are still being poorly maintained it seems, they account for several GBs of disk space which seems crazy high for just logs:

Example: Note that logs for

@nebulon said in Safe to truncate /home/yellowtent/platformdata/logs/* when large disk consumer?:
@d19dotca is it possible that the missing logrotate files would be for already uninstalled apps and those large log files are just not cleaned up after uninstallation?
No, unfortunately not. That has never been the case either, wish it was that easy.
haha. I reported earlier in this thread that re-saving an app with from Location tab will regenerate the logrotate configs for the app. They just go missing randomly, no idea why they disappear, but I at least know how to get them back. Unfortunately I am not aware of any of this until I randomly check sizing on my server and find incredibly large log files which then leads me to discover the apps are missing logrotate configs. Saving the app again so it sort of rebuilds itself will regenerate it. I just looked now and there are a bunch more, for example: I didn't do anything beyond restoring the Cloudron backup to a new Cloudron instance in the Vultr Marketplace last night:ls -alh /home/yellowtent/platformdata/logrotate.d total 156K drwxr-xr-x 2 root root 4.0K May 31 03:54 . drwxr-xr-x 15 yellowtent yellowtent 4.0K May 30 06:27 .. -rw-r--r-- 1 root root 946 May 30 06:28 00895422-a1ff-4196-8bb8-cb4ff8d6eeaa -rw-r--r-- 1 root root 946 May 30 06:28 02b2f762-afa4-4278-afaa-5c07ad29715e -rw-r--r-- 1 root root 946 May 30 06:28 05db518f-2c45-411b-865f-813dbf85c244 -rw-r--r-- 1 root root 946 May 30 06:28 1247a348-c8da-4f30-8a4c-3fa014f092a1 -rw-r--r-- 1 root root 946 May 30 06:28 134ef7f1-46f8-403e-8ac5-a3297b37893f -rw-r--r-- 1 root root 946 May 30 06:28 200d36ca-8109-409a-9b56-07f46c2f09bd -rw-r--r-- 1 root root 946 May 30 06:28 21aecd6a-398a-433a-a954-5bcd5f861e20 -rw-r--r-- 1 root root 946 May 30 06:28 29354a9c-7e1d-4986-b78e-3510fe73b370 -rw-r--r-- 1 root root 946 May 30 06:28 3167ef7d-e4c2-4072-8e11-8de49c5db970 -rw-r--r-- 1 root root 946 May 30 06:29 38f883dc-4047-4237-a6a1-3ecd77efcde9 -rw-r--r-- 1 root root 946 May 30 06:28 40ae3d28-d67f-453e-895d-0f22b539372c -rw-r--r-- 1 root root 946 May 30 06:29 4929b73d-cfa4-4246-82a7-4bc8127982f6 -rw-r--r-- 1 root root 946 May 30 06:29 492b4264-fea8-4d52-bbe6-1f15ce72c53a -rw-r--r-- 1 root root 946 May 30 06:29 493c4f88-5d4d-40e5-8361-fd7d4541441d -rw-r--r-- 1 root root 946 May 30 06:29 4d2fc2b7-2475-4c6b-97b4-4f896fbe8e9e -rw-r--r-- 1 root root 946 May 30 06:29 6120f84a-0953-4982-9167-ef872c0ee49a -rw-r--r-- 1 root root 946 May 30 06:29 633f2c77-9b33-457a-bc3c-919c87d25ca2 -rw-r--r-- 1 root root 946 May 30 06:29 64098702-00d1-4d2e-8d27-4597e100d1c9 -rw-r--r-- 1 root root 946 May 31 03:54 6b3ebc4f-9708-4243-bc21-4c9a01bc3499 -rw-r--r-- 1 root root 946 May 30 06:29 6e21d87b-ea85-420b-8eed-8b14d601438d -rw-r--r-- 1 root root 946 May 30 06:30 76aa4cfd-a1c7-451a-a11e-a4fabe5ff95b -rw-r--r-- 1 root root 946 May 30 06:29 8315f008-87e9-4f62-9ae8-1938d7b3f9b2 -rw-r--r-- 1 root root 946 May 30 06:29 8732aed0-273e-49f5-837f-cd9c600bf7b9 -rw-r--r-- 1 root root 946 May 30 06:30 8dba8d47-7890-49d3-8dfa-970e1ec52991 -rw-r--r-- 1 root root 946 May 30 06:30 95c45c33-bd8a-4fae-9718-509c69456abe -rw-r--r-- 1 root root 946 May 30 06:30 9f9aba4a-f7b1-44d8-859c-c6953027c39e -rw-r--r-- 1 root root 946 May 30 06:30 9fdedb7f-1bd4-42f6-a7e8-9831df9da8dd -rw-r--r-- 1 root root 230 May 28 17:54 box -rw-r--r-- 1 root root 946 May 30 06:30 c3ddc268-deef-49e0-8e3a-97e174cf0594 -rw-r--r-- 1 root root 946 May 30 06:31 c40f9f5f-037c-4a1d-8538-f1f4d4b82f5d -rw-r--r-- 1 root root 946 May 30 06:32 d3121e48-4196-48fe-907d-ee831e11ce5c -rw-r--r-- 1 root root 946 May 30 06:32 e18fa18b-b176-4b25-bf78-4d82c022b0f5 -rw-r--r-- 1 root root 946 May 30 06:33 e50f78c7-da6e-4036-a1a3-0cc934448cf1 -rw-r--r-- 1 root root 946 May 30 06:31 ea2ee30a-8d3b-4a3b-8817-19b0f1e17bd7 -rw-r--r-- 1 root root 946 May 30 06:31 ed41aa60-ff4d-4e8e-8796-8c7de4bdf1a9 -rw-r--r-- 1 root root 946 May 30 06:31 f6b21e27-6d25-4c69-a547-0466e622d719 -rw-r--r-- 1 root root 1.1K May 28 17:54 platform -
This is still an issue by the way. Noticed my disk space accumulating quickly. There's practically no logrotate's configured. Is this due to 6.3 though perhaps?

Then I need to run the logrotate function manually to save the disk space again.I'm actually a little surprised this would be an issue when all the containers already had to be regenerated as part of the 6.3 upgrade.
@staff - I'm concerned that this defect hasn't been fixed since it was reported quite a while back. Any possibility of getting to the bottom of this one sooner than later?
-
I took the time to manually re-save each app Location tab to recreate the logrotate file as per the workaround, which resulted in a bit of downtime for each app.
I then ran the
sudo logrotate -f /home/yellowtent/platformdata/logrotate.d/*command and saved roughly half a GB in logs directory alone (I see the mongodb and graphite folders among others went much smaller too, presumably due to restarting of the apps?). So basically 500 MB in extra logs and that's only on a server that's been running for only about a week, presumably would have grown much further in just another week or two too if the logrotate files weren't regenerated.I really hope this will be fixed in the next bug-fix release.

@d19dotca if you reconfigure the location of one of the missing apps, does the logrotate config file show up afterwards? I am wondering if something is purging them after they are created. Looking at the code I cannot spot why it wouldn't create that file.
-
@nebulon Yes, I think I've mentioned that before too. Re-saving from the Location tab on each app regenerates the logrotate file and finally the logrotates will proceed successfully.
I know @girish confirmed that he saw the same behaviour on one of your (or his) servers too. So this definitely seems to be a Cloudron bug that needs fixing.
This issue has been sitting a long time (confirmed/reproduced in February 2021), so hoping this gets resolved soon because this keeps causing issues on my server when it comes to disk space consumption alerts.
