Ramon, thank you for the detailed test case, I was able to run through it exactly as you described, both as root user (see attached) and as nagios (with sudo setup). I suspect I'm unable to reproduce the issue you're seeing since under lxc the /sys/kernel/debug directory belongs to the host and thus is owned by nobody:nogroup, (although I should think that it would produce a permission denied error.) >From the host: # mount | grep tracing tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime) In any case, regarding the bug itself, I am able to detect the permissions error: # /usr/lib/nagios/plugins/check_disk -e DISK CRITICAL - /sys/kernel/debug/tracing is not accessible: Permission denied # ls -la /sys/kernel/debug/tracing ls: cannot access '/sys/kernel/debug/tracing': Permission denied # /usr/lib/nagios/plugins/check_disk -e -X tracefs DISK OK| /=44420MB;;;0;3754403 /dev=0MB;;;0;0 /dev/full=0MB;;;0;16018 /dev/null=0MB;;;0;16018 /dev/random=0MB;;;0;16018 /dev/tty=0MB;;;0;16018 /dev/urandom=0MB;;;0;16018 /dev/zero=0MB;;;0;16018 /dev/fuse=0MB;;;0;16018 /dev/net/tun=0MB;;;0;16018 /dev/lxd=0MB;;;0;0 /dev/.lxd-mounts=0MB;;;0;0 /dev/shm=0MB;;;0;16041 /run=16MB;;;0;16041 /run/lock=0MB;;;0;5 /sys/fs/cgroup=0MB;;;0;16041 /var/lib/lxd/shmounts=0MB;;;0;0 /var/lib/lxd/devlxd=0MB;;;0;0 /run/user/1001=0MB;;;0;3208 The suggestion in comment #16 looks like the best approach for addressing the issue so far. Alternatively, I posted a patch to LP #1827159 for altering check_disk itself, however as mentioned in comment #9 on this bug, excluding all tmpfs would be too broad. Ramon, if you can test out the approach outlined in comment #16 and let me know if it seems suitable for your use case, perhaps we should proceed with implementing an SRU for that. ** Attachment added: "Screenshot from 2019-07-17 14-19-10.png" https://bugs.launchpad.net/ubuntu/+source/nagios-plugins/+bug/1516451/+attachment/5277690/+files/Screenshot%20from%202019-07-17%2014-19-10.png -- You received this bug notification because you are a member of AIMS, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 Status in nagios-plugins package in Ubuntu: Incomplete Bug description: I didn't touch my Nagios config, just update my system from 15.04 to 15.10.

[Aims] [Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
The reason why this alert pops out is related to running sosreport on this node. Nagios can not access it - which is good as this directory is only accessible by root: # ll /sys/kernel/debug/ | grep trac drwx-- 8 root root 0 Jul 9 09:06 tracing/ To validate/replicate this behaviour, please open three terminals. Terminal 1, run mount | grep -i tracing - no output here as this directory is generally not presented by mount Terminal 2: mkdir testing; cd testing while true;do mount | grep -i tracing > mounted-$(date +%s); done on terminal 1 please run cd testing watch ls -lt Terminal 3 sudo sosreport -a --all-logs Watch Terminal 1. On the beginning, you will see files created with 0 in size. When you start sosreport in another window/tmux this file gets populated - meaning munt can see it. Why does it become available? Sosreport gathers diagnostic information and initiates it. This directory is not visible from mount during normal operation. -- You received this bug notification because you are a member of AIMS, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 Status in nagios-plugins package in Ubuntu: Incomplete Bug description: I didn't touch my Nagios config, just update my system from 15.04 to 15.10.

[Aims] [Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
This looks similar to https://bugs.launchpad.net/ubuntu/+source /monitoring-plugins/+bug/1827159. However, installing nagios-plugins in a fresh Xenial LXC container does not appear sufficient to reproduce the bug: 1. There is no /sys/kernel/debug/tracing present on the system. Installing perf-tools-unstable caused the directory to be created. 2. There is not a nagios user on the system. I created this manually, but wonder if there is some third component that should be installed, that would create this? 3. The directory in question is owned by 'nobody': root@triage-xenial:~# ls -l /sys/kernel/debug/tracing ls: cannot access '/sys/kernel/debug/tracing': Permission denied root@triage-xenial:~# ls -l /sys/kernel (...) drwx-- 36 nobody nogroup0 Jul 10 23:10 debug (...) It would be quite helpful to have a step-by-step test case that can be invoked in a Xenial lxc container. Has anyone checked that this same issue affects bionic or newer, or is Xenial-specific? ** Changed in: nagios-plugins (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of AIMS, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 Status in nagios-plugins package in Ubuntu: Incomplete Bug description: I didn't touch my Nagios config, just update my system from 15.04 to 15.10.

[Aims] [Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
Since check_all_disks is internally defined in Nagios, you might well
see a "duplicate definition" error if you define your own
check_all_disks command. I'd recommend
define command{
command_name check_all_physical_disks
command_line /usr/lib/nagios/plugins/check_disk -w '$ARG1$' -c '$ARG2$' -e
-A --exclude-type=tracefs --exclude-type=cgroup
--exclude_device=/run/lxcfs/controllers
}
instead, and then call that in your host definition:
define service {
use generic-service
hostgroup_name all
service_description Disk Space
check_command check_all_physical_disks!6%!4%
}

[Aims] [Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
We normally netboot but we had a few machines that would not PXE, so we installed 14.04 via medium. Afterwards, some of the medium-installed machines were throwing this error in Nagios. Found this line in /etc/mtab on the afflicted hosts: tracefs /var/lib/ureadahead/debugfs/tracing tracefs rw,relatime 0 0 This appears to be an artifact on the medium-based install process. I removed the above line and ran: sudo service nagios-nrpe-server restart Error condition cleared. -- You received this bug notification because you are a member of AIMS, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 Status in nagios-plugins package in Ubuntu: Triaged Bug description: I didn't touch my Nagios config, just update my system from 15.04 to 15.10.

[Aims] [Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
Rather than excluding tmpfs, just exclude /run/lxcfs/controllers. This
is the check_all_disks command I'm now using in my /etc/nagios-
plugins/config/disk.cfg:
# 'check_all_disks' command definition
define command{
command_namecheck_all_disks
command_line/usr/lib/nagios/plugins/check_disk -w '$ARG1$' -c
'$ARG2$' -e -A --exclude-type=tracefs --exclude-type=cgroup
--exclude_device=/run/lxcfs/controllers
}
