A new version of check_netio, a monitoring plugin to monitor network interfaces on Linux operating systems, is available!

Version 1.5 added the selected interface's drop statistics to the default performance data output. 

Additionally to this, the system wide tcp statistics can optionally be added to the plugin's performance data. Just use the new parameter -t for this purpose:

/usr/lib/nagios/plugins/check_netio.sh -i eth0 -t
