[Bug 1827159] Re: check_all_disks includes squashfs /snap/* which are 100%
Was able to reproduce using the command in /etc/nagios- plugins/config/disk.cfg; I've added this as a test case in the report body. Adding -X squashfs did nothing, but -X tmpfs worked: # /usr/lib/nagios/plugins/check_disk -w 10 -c 10 -e -X squashfs DISK CRITICAL - free space: /dev 0 MB (100% inode=99%); /dev/lxd 0 MB (100% inode=99%); [...] # /usr/lib/nagios/plugins/check_disk -w 10 -c 10 -e -X tmpfs DISK OK| /=71MB;119160;119160;0;119170 monitoring-plugins-gu/plugins/check_disk.c includes some filtering code, which skips: * Remote file systems (me_remote) * Pseudo file systems (me_dummy) * Excluded filesystems (fs_exclude_list) * Excluded filesystem types (dp_exclude_list) Looks like by default the fs_exclude_list has only one fs type added to it: np_add_name(_exclude_list, "iso9660"); Maybe a possible patch might be to add tmpfs there too (see attached; untested)? ** Patch added: "check_disk_no_tmpfs.patch" https://bugs.launchpad.net/nagios-charm/+bug/1827159/+attachment/5273538/+files/check_disk_no_tmpfs.patch ** Tags added: server-next -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827159 Title: check_all_disks includes squashfs /snap/* which are 100% To manage notifications about this bug go to: https://bugs.launchpad.net/nagios-charm/+bug/1827159/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
