Zabbix Server FPING Timeout With Response Above 500ms - 6.4.11

[GLOBALSAT]

Hi Zabbix Community

I've deployed a Zabbix Server Version 6.4.11 on a Virtual Machine which is Running Debian 12 Bookworm.

I succesfully deployed the server. But i am now facing a challeng that i was unable to find a solution. I have a couple of devices that runs over satellite connection and each ICMP Echo package will take up to 3000 miliseconds to gets back to the server itself.

After deploying some deviecs, i realized that my server is unable to ping those devices by using the default ICMP Template Net ICMP Ping Generated by official Zabbix template tool "Templator". After some research here at the forum i figured out that fping is in charge to run the icmp towards each device on the zabbix server.

When i run the regular ICMP options that fping uses, fping expects by default that each reply is within 500ms, which is not my case here. My server is running fping fping/stable,now 5.1-1 amd64 [installed,automatic].

Take a look at mt tests below:

fping -l 10.223.233.3
10.223.233.3 : [0], timed out (NaN avg, 100% loss)
10.223.233.3 : [1], timed out (NaN avg, 100% loss)
10.223.233.3 : [2], timed out (NaN avg, 100% loss)
10.223.233.3 : [3], timed out (NaN avg, 100% loss)
10.223.233.3 : [4], timed out (NaN avg, 100% loss)
10.223.233.3 : [5], timed out (NaN avg, 100% loss)
10.223.233.3 : xmt/rcv/%loss = 6/0/100%

fping -l -t 3000 10.223.233.3
10.223.233.3 : [0], 64 bytes, 2028 ms (2028 avg, 0% loss)
10.223.233.3 : [1], 64 bytes, 1028 ms (1528 avg, 0% loss)
10.223.233.3 : [2], 64 bytes, 1148 ms (1401 avg, 0% loss)
10.223.233.3 : [3], 64 bytes, 2650 ms (1713 avg, 0% loss)
10.223.233.3 : [4], 64 bytes, 1808 ms (1732 avg, 0% loss)
10.223.233.3 : [5], 64 bytes, 2087 ms (1791 avg, 0% loss)
^C10.223.233.3 : [6], timed out (1791 avg, 14% loss)

10.223.233.3 : xmt/rcv/%loss = 7/6/14%, min/avg/max = 1028/1791/2650

The consequence is that any device that reply ICMP outside the time expected, the Server execute the triggers(See attachment).

Question: Does anyone know how/where i can tune my fping/zabbix configuration to allow a timeout greater than 500ms?

I appreciate your attention

Hello,

It's a pity that no one wanted to answer this seemingly simple question.
Have a look at the item configuration in the documentation and change the key for these systems.

https://www.zabbix.com/documentation/current/en/manual/config/items/itemtypes/simple_checks#icmppingloss

There you have to adjust the timeout value.
It is a pity that the original templates do not use macros here.
You could overwrite a template profile (example=profile_satelite_systems) for the relevant systems at host level / or at template level.

If you are not yet familiar with Zabbix, you can clone the template and change the key for the relevant systems.

Is the topic still relevant?
