nagios-plugins-for-linux

What's new in this release

Enhancements

The build system, the plugins and libraries are been reworked in order to support some older Linux kernels and (gcc) compilers. The nagios-plugins-linux can now be compiled and run on older linux systems, notably RHEL 5 (gcc 4.1.2, kernel 2.6.18).

check_memory: new option -a|--available for selecting the kernel counter MemAvailable instead of the default one (memory used). This feature requires a Linux kernel 3.14 or better. For older kernels the plugin falls back to the free memory counter.

Fixes

check_tcpcount: do not exit with error opening /proc/net/tcp6 when the command line option --tcp6 has not been specified.

cpustats library: do not exit with an error message if softirq cannot be found in /proc/stat. This entry is not provided by old kernels.
