 Here's the setup for debian systems:
-  * Download the [[http://exchange.nagios.org/components/com_mtree/attachment.php?link_id=473&cf_id=30|check_netio_1.1]] to /usr/local/bin and test it. You will have to change paths, like this: [[check_netio_1.1]]
+===== For all monitores systems =====
+Download the [[http://exchange.nagios.org/components/com_mtree/attachment.php?link_id=473&cf_id=30|check_netio_1.1]] to /usr/local/bin and test it. You will have to change paths, like this: [[:blogfiles:check_netio_1.1_debian]] Copy this file to all your servers that you check by ssh.
+===== On the nagios server only: =====

+You need these commands to enable netio checking for a hostgroups based configuration.
+<code>
+# 'ssh_netio' command definition
+define command{
+        command_name ssh_netio
+        command_line /usr/lib/nagios/plugins/check_by_ssh -H $HOSTADDRESS$ -C "/usr/local/bin/check_netio_1.1 -i $ARG1$"
+}
+define hostgroup {
+        hostgroup_name  netio-servers
+        }
+define service{                                                                            use                             generic-service         ; Name of service template to use                                                                                 hostgroup_name                  netio-servers
+        service_description             NETIO
+        check_command                   ssh_netio!eth0                                           }
+</code>
+To enable netio checking for a given host, add the entry ''netio-servers'' to the ''hostgroups'' of the ''host'' entry.
+Restart nagios using ''/etc/init.d/nagios3 restart'' to make sure everything works. Nagios should check the NETIO service.
+To enable nagiosgrapher display for the netio plugin copy the file [[:blogfiles:check_netio_1.1_debian]] to ''/etc/nagiosgrapher/ngraph.d/extra/netio.ncfg''
+Restart nagiosgrapher and control ''/var/log/nagiosgrapher/ngraph.log''. For every host where you enable netio checking, you should see the information that the config has been added.
+Note:
+  * If you run a bastille hardened server, the plugin call by ssh may fail because ifconfig can't be executed. Test it using
+  /usr/lib/nagios/plugins/check_by_ssh -H newton.ksk.ch -C '/usr/local/bin/check_netio_1.1 -i eth0'
