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 Ubuntu Bugs, which is subscribed to 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-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
