Ping external ip from zabbix agent

[target]

Hello All,

I am trying to ping a VPN IP Address from a Zabbix agent but unfortunately it doesn't work.
I have placed the below into Zabbix agent configuration.

UserParameter=CheckVPN,fping x.x.x.x | grep alive | wc -l

And have created an item with type zabbix agent(active), key CheckVPN


I have followed the instructions from this old post below:

https://www.zabbix.com/forum/zabbix-help/18593-ping-an-external-ip-address-from-a-zabbix-agent

Can anyone help?


Thanks.

What exactly means "it doesn't work"? Very hard to suggest something, if you don't give us details.. Error messages for example? versions, just in case...

Hi Cyber,

Yes you are right. Finally I made it work. Get ping results from VPN via Zabbix Agent.


Windows agent configuration
UnsafeUserParameters=1
UserParameter=local.ping[*],ping $1 -n 1 |find "TTL=">NUL && echo 1 || echo 0


ITEM
Zabbix agent
KEY: local.ping[192.168.0.1]


TRIGGER
last(/VM22/local.ping[192.168.0.1])=0



*(Change the IP Address to your VPN IP Address you want to monitor)


Hope that helps someone else.

Hi target
hope you are doing well
I'm new to Zabbix and am trying to ping to VPN and its worked actually and asking if you could make brief explanation about the userparameter that you mentioned in windows agent and how dose this configuration work?

For windows agent you may try this template. It works without any userparemeters.

UserParameter is a method to define custom "keys" (alias) for a command.

If you want to run a ping from Windows, in cmd you write

ping 8.8.8.8

If you only want to test if device is alive or not running ping, you can use

ping 8.8.8.8 -n 1 |find "TTL=">NUL && echo 1 || echo 0

If device is alive, this command returns 1, if its dead returns 0. Try it.

Now, let's create the alias (UserParameter), so in zabbix_agent.d/ you can create a conf (set the name u want, for example, windows.parameters.conf) and add this line

UserParameter=local.ping[*],ping 8.8.8.8 -n 1 |find "TTL=">NUL && echo 1 || echo 0

Now you want to ping this IP from agents, but tomorrow the IP change and you dont want to change the windows.parameters.conf on all machines... so its a better way to pass the IP as a parameter. Just change 8.8.8.8 to $1


UserParameter=local.ping[*],ping $1 -n 1 |find "TTL=">NUL && echo 1 || echo 0

Now restart the Zabbix Agent service on Windows client, and add the Item to template

Type: Zabbix Agent (active or passive, what u prefer)
Key: Alias given in the conf file local.ping[*] , but change * to the IP u want to check --> local.ping[8.8.8.8]


If you want to check another IP, just add another item and just change IP to the other IP u want to check --> local.ping[8.8.4.4]



You can create many user parameters as you need, you only need to reload / restart service to zabbix agent load the changes on files. Here is my windows.parameters.conf https://github.com/guillerg86/zabbix...arameters.conf
