vpn monitoring

[Riley69]

Hi,

I have a zabbix server setup on one server and a vpn server on another machine. I want to monitor whenever the vpn connection drops on the vpn server and execute a script on the vpn server to automatically restart the vpn client on it. I should also receive an alert whenever this occurs. Can someone please help me on this. (please notice the overuse of the word "on".)

Hi,
You need to provide more information. How would determine this information manually?

Hi Yello,

Thanks for the reply. I have a ping script on the vpn that pings the external vpn IP and a script that restarts vpn. Is it possible to run commands remotely on the vpn server and execute the scripts in that order?

Hi,
Yes, you can configure "UserParameter" functions which are user defined functions that the agent runs. You add them to the agent configuration.

You'll find plenty of references to them in the forum and zabbix docs. Remember that you will probably need to trim the output to return the data type that is expected by the item configured in zabbix.

Thank you for the prompt reply. I will have a look at that

It is enough to use:

Item:
- Simple Check - icmpping[ip_address_on_the_other_side] item
Trigger:
- {Template ICMP All:icmpping.last(120)}=0

Action script:
/usr/local/share/zabbix/alertscripts/reser_vpn.sh

-----
reset_vpn.sh
-----
#!/bin/bash
ssh login@IP_VPN_SERVER "/usr/local/bin/reser_my_vpn_server.sh"

And set the login via SSH keys for user zabbix !

Best
