Here is it, version 18 of the Nagios Plugins for Linux.
It’s manly a bugfix release with a fix for an issue recently pointed out by Paul Dunkler: some of the plugins did not terminate with the correct return code when reaching a warning or critical threshold.
The check_memory plugin no more reports as cached memory the unreclaimable slab values, which cannot be reclaimed even under memory pressure.
The check_cpu plugin executed with the ‘-i | —cpuinfo‘ switch, now correctly detect on 64-bit architectures the CPU 64-bit op-mode.
A minor memory resource leak reported by the Coverity Scan tool has also been fixed.
As usual, bug reports, feature requests, and ideas for improvements are welcome!
