check_updates

check_updates is a Nagios plugin to check if RedHat or Fedora system is up-to-date

Security

If at least a security update is available the plugin will return a critical status. This can be overridden with the --number-only command line option

DNF

DNF uses different caches per user. This has the consequence that DNF and the plugin will potentially deliver different results for different users.

• Fedora, Red Hat Enterprise Linux 6.x, CentOS 6.x, Scientific Linux 6.x systems:
