Check tunX device / perhaps with external ping

[Beam]

Hi,

i want to check the availibilty of some tun devices, e.g. tun0,tun1, tun2, tun3 on a server, where no zabbix_agentd could be running. My first thought was an external check. So i created the /etc/zabbix/externalscripts directory and the following line in /etc/zabbix/zabbix_server.conf:

ExternalScripts=/etc/zabbix/externalscripts/

Then i restarted the zabbix server and create the following script check_ping.sh (works fine in console):

#!/bin/bash
#$1 = hostname, can be ignored
#$2 = target
date >> /tmp/check_ping.log
echo `fping $2 | grep alive -c`

The 4th line is only to check if the script is executed. The rights for the script are 777.

In the webui i created an item with type "external check" and key check_ping.sh[10.0.0.5].

It shows External check [check_ping.sh[10.13.50.200]] is not supported, same in the server log.

I've read about a patch for external scripts, is it neccesary with the debian testing package? Its 1.4.1.

Maybe there is a better solution? One solution is to create a host with the IP of the interface, but i think thats not arranged well.
