imfile-state files are not removed #4186

dwerder · 2020-02-20T10:04:13Z

Expected behavior

imfile-state:<inode>:<hash> files should be deleted if logfile is rotated/changed

Actual behavior

imfile-state files are not deleted.

Steps to reproduce the behavior

Install rsyslog version 8.2001.0-3 and have fast rotated log files. Also we see that our logs always switch just a few inode (don't know if that info helps)

Since merge of #3990 we do not have the problems that log entries are resend, but we have servers with thousends and thousends of that imfile-state files.

Environment

rsyslog version: 8.2001.0 (aka 2020.01)
platform: CentOS Linux release 7.7.1908 (Core)
for configuration questions/issues, include rsyslog.conf and included config files

The text was updated successfully, but these errors were encountered:

rgerhards · 2020-02-20T10:08:31Z

At the bottom, this is a feature. I am not sure if we added a config option to turn it off.

Here it is why we do not delete state files: we have many users who move log files around, even between monitored locations. They do not want rsyslog to re-sent data already sent from a different location. Thus we need to keep the state file as we never know when and where the original log file is moved in again.

That said, I think I remember a request to make this configurable. @jvymazal do you know it our of your head?

dwerder · 2020-02-20T10:14:17Z

So what should we do with that files? When can they securly be deleted? We have servers who generes 20k of this files each day.

dwerder · 2020-02-20T10:16:11Z

We can implement a workaround like a cron, which deletes the files every 5 min, when they are older then a few minutes. But how do we know if that would not break stuff for rsyslog?

jvymazal · 2020-02-20T10:16:22Z

@dwerder can you confirm that these stae-files are new (created by rsyslog after #3990)? I was under impression that by that we covered all possible scenarios and deletes should now happen for these files...

dwerder · 2020-02-20T10:17:11Z

They were created with the 8.2001.0 version. We did it on fresh installed mashines

jvymazal · 2020-02-20T10:17:36Z

also @rgerhards it is indeed configurable, see https://www.rsyslog.com/doc/v8-stable/configuration/modules/imfile.html#deletestateonfiledelete but by default it is on meaning that rsyslog should actually delete the files.

dwerder · 2020-02-20T10:25:49Z

We will try to explicite enable it. And then all the files should be deleted or do we need already existing files.

jvymazal · 2020-02-20T10:27:21Z

Ok, now that I am thinking about it more, @dwerder are you seding HUP to rsyslog upon file rotations? If not, and you did not configure forced PersistStateInterval to happen at least once in between file rotations than deleting the state-files will not work.

jvymazal · 2020-02-20T10:30:10Z

Also, as for the old files, if rsyslog is restarted and did not delete them than it will never delete them so you have to do it manually (the older hashes are not persisted anywhere)

dwerder · 2020-02-26T14:06:20Z

Hello @jvymazal . We tried it with the kill Hup systemctl kill -s HUP rsyslog.service. The /var/lib/rsyslog/ dir was cleand and empty.
We still see that files are created and not removed. New files are created after each HUP.

First we used inotify and saw that the files are still created and we see that warning on each HUP.

I like to mention that it is one log file and it is rotate multiple times within a minute.

jvymazal · 2020-02-27T08:35:02Z

@rgerhards please correct me if I am wrong but sending HUP should force persisting of imfile statefiles, right?

rgerhards · 2020-02-27T12:22:13Z

@jvymazal think so, but not 100% sure - sorry, heading from teleconf to teleconf today... Will check ASAP.

ChenQianCQ · 2020-05-20T07:19:39Z

i am also hit this issue with version 8.2002.0 .
it is very simple to reproduce.

write a log file by bash like this.
#! /bin/bash
i=0
while [ 1 ];do
i=expr $i + 1
echo "$i" >> /opt/1.log
done
remove the log file "/opt/1.log" .
rm -rf /opt/1.log
in /var/lib/rsyslog

Would you please also post relevant configuration snippet you use in reproducing?
Also, do you have rsyslog running all the time or do you stop/restart it any time?

Thanks

i am add my own configuration in /etc/rsyslog.d directory. the configure file is like this (it is syslogmgr-collect.conf, but can't upload, so i change to text format)
syslogmgr-collect.txt

and, the rsyslog process is always running , NO excute stop/restart/kill/...... operation.

May thanks for info, I will look into it once I have a moment.

ChenQianCQ · 2020-06-16T09:00:34Z

@jvymazal ，do you have any update on this issue ？

zbukhari-apex · 2023-12-21T18:38:10Z

I'm running into this as well. A slew of versions but using Ubuntu:

No state file surprisingly but behaving as it should:
Trusty (i.e. 14.04) - 7.4.4-1ubuntu2.7
Xenial (i.e. 16.04) - 8.16.0-1ubuntu3.1

State file behaving as it should:
Bionic (i.e. 18.04) - 8.32.0-1ubuntu4.2

/var/spool/rsyslog contains imfile-state:-var-log-audit-audit.log it does not leave stale files around.

Problem started:
Focal (i.e. 20.04) - 8.2001.0-1ubuntu1.3
Jammy (i.e. 22.04) - 8.2112.0-2ubuntu2.2

/var/spool/rsyslog contains ... a lot of imfile-state:8620608:ffa5e1b5ced716b0 with the file ID hash changing and the old files not being cleaned up. Documentation says deleteStateOnFileDelete is set to on. It doesn't cleanup. I tried to set it explicitly, it still doesn't clean up. I tried legacy syntax, that doesn't work either. I tried different modes, still doesn't work.

I have debug output if desired. Current for 8.2112.0 but if it would help for another version, let me know and I can do that for you.

This became an issue as we use rsyslog to process and send auditd (i.e. linux-audit) logs. Some of our servers have a lot of activity and this caused us to run out of inodes. Very rare overall but a thing I'm sure many Linux admins do. There used to be an rsyslog wiki page which showed how to use rsyslog for auditd logging. That's pretty much our setup. I don't have that link anymore but it's probably going to be similar to this. We use UDP but pretty much the same setup.

https://linux-audit.com/central-audit-logging-configuration-collecting-linux-audit-events/

zbukhari-apex · 2023-12-21T21:39:26Z

I have noticed that the unlink call via strace does not have the actual file name. It shows it in the rsyslog debug logs but when performing strace -f -e trace=file -p PID_OF_RSYSLOG, the actual call is incomplete. It's like the filename is missing the last colon. Looking at the source I can't see where this is incorrect as the debug log prints out statefn. There is an unlink call below it unlink((char *)statefn);.

https://github.com/rsyslog/rsyslog/blob/master/plugins/imfile/imfile.c#L1063

In the rsyslog debug logs essentially (20 lines before and 20 lines after "deleting state file"):

Here via strace you can see the argument supplied to unlink is missing the file ID hash.

I found this to be similar - updated a month ago - trying to see if this will work: #5258

The fix used in #5258 did not work for me. Stale files are still left and the unlink call is not given the right argument.

I am also hit this issue with version 8.2312.0.
Has this issue been resolved or is there any workaround that can support this “deleteStateOnFileDelete="on"”?
