You can use the --exclude-type option to work this bug around: /usr/lib/nagios/plugins/check_disk -e --exclude-type=tracefs -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-plugins/+bug/1516451/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
Thank you for taking the time to report and investigate this bug and helping to make Ubuntu better. It sounds to me like check_disk should have a blacklist of filesystem types to ignore. But explicitly specifying which mount points looks like a suitable workaround. I wonder if this affects monitoring-plugins in Xenial? ** Changed in: nagios-plugins (Ubuntu) Importance: Undecided => Medium ** Changed in: nagios-plugins (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-plugins/+bug/1516451/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
I suspect there isn't a code change here, but rather a difference in the way Ubuntu is presenting its mount points. The plugin tries to enumerate and check all mounts. A better use might be to add the actual mount points to be monitored with -p /usr/lib/nagios/plugins/check_disk -w '20%' -c '10%' -e -p / -p /var -p /boot 12.04: mount none on /sys/kernel/debug type debugfs (rw) 14.04: debugfs on /sys/kernel/debug type debugfs (rw,relatime) tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-plugins/+bug/1516451/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1516451] Re: check_disk plugin broken after upgrade to 15.10
strace confirms that check_disk on 12.04 doesn't check /sys/kernel/debug/tracing Not having any luck tracking down a code change in the monitoring- plugins github repo. I wonder if this is a change in a dependent lib instead. Here's a workaround sudo chown root:root /usr/lib/nagios/plugins/check_disk sudo chmod u+s /usr/lib/nagios/plugins/check_disk sudo chmod o+x /usr/lib/nagios/plugins/check_disk -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-plugins/+bug/1516451/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Also note that while 15.10 does change the permissions on /sys/kernel/debug/tracing (from drwxr-xr-x in 15.04 to drwx-- in 15.10), the permissions on /sys/kernel/debug are drwx-- on both 15.10 and 15.04 - which means that /sys/kernel/debug shouldn't be readable from a non-root account on either release, so this looks like a code change in check_disk. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nagios-plugins in Ubuntu. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-plugins/+bug/1516451/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
