[Pkg-nagios-devel] Bug#863797: monitoring-plugins-basic: unable to use check_disk inside /var/tmp

[Emmanuel DECAEN]

Package: monitoring-plugins-basic
Version: 2.2-3
Severity: important

Dear Maintainer,

After upgrade, check_disk on /var/tmp/mysql is broken.

Status using nrpe (wrong):
DISK CRITICAL - /var/tmp/mysql is not accessible: No such file or directory

Status using bash (works correctly):
$ /usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /var/tmp/mysql
DISK OK - free space: /var/tmp/mysql 10187 MB (99% inode=99%);|
/var/tmp/mysql=42MB;8184;9207;0;10230

In nrpe, system wide /var/tmp is no more reachable
$ grep "/var/tmp" /proc/11489/mountinfo
115 113 254:2 / /var/tmp/mysql rw,noatime,nodiratime shared:65
master:32- xfs /dev/mapper/v1-tmp rw,attr2,inode64,noquota

/tmp/systemd-private-b35c254c031041979d3126e02a0c5c51-nagios-nrpe-server.service-7xjqpw/tmp
