1.7.0

This release adds a verification check on the network interface whether it is up. If not, the plugin will alert:

ck@bookworm:~$ ./check_netio.sh -i ens35
CHECK_NETIO CRITICAL - Interface ens35 is down

1.6.0

Introducing new parameter -r (short for regular expression) which awaits a comma-separated list of strings. These given strings will be matched against the tcp statistics (invoked with -t). This way the tcp statistics can be cut to only a few ones, deemed important by the user.
And this also helps to avoid NRPE cutting the performance data output, because the output becomes too large (fixes #11 ).

1.5.2

Bugfix #9

1.5.1

Bugfix issue-6 (#7)

1.3

Release 1.3 removed the dependency of the file /usr/lib/nagios/plugins/utils.sh which is part of either monitoring-plugins-common or nagios-plugins-common package.

1.2

Release 1.2 gets rid of the previously used method to launch ifconfig in the background. Instead the plugin parses /proc/net/dev directly. See also #1 .
