Zabbix 5.0 Triggers High bandwidth usage

[madj]

Hello everybody,

I'm using template "Module Interface SNMPv2" with item prototypes, trigger prototypes. I have this trigger for high bandwidth usage:




({Template Module Interfaces SNMPv2:net.if.in[ifHCInOctets.{#SNMPINDEX}].avg(15m)}>({$IF.UTIL.MAX:"{#IFNAME}"}/100)*{Template Module Interfaces SNMPv2:net.if.speed[ifHighSpeed.{#SNMPINDEX}].last()} or

{Template Module Interfaces SNMPv2:net.if.out[ifHCOutOctets.{#SNMPINDEX}].avg(15m)}>({$IF.UTIL.MAX:"{#IFNAME}"}/100)*{Template Module Interfaces SNMPv2:net.if.speed[ifHighSpeed.{#SNMPINDEX}].last()}) and

{Template Module Interfaces SNMPv2:net.if.speed[ifHighSpeed.{#SNMPINDEX}].last()}>0




The following items :

SNMPv2:net.if.speed[ifHighSpeed.{#SNMPINDEX} is the interface bandwidth capacity. Most of the time 100Mbps or 1Gbps.




But I want to monitor different WAN Link with different Value. For example

200Mbps | 500Mbps




And I want to have alert when I'm using 90% of my wan link.

This is for different location, different device and interfaces.

So I would like to know if someone know how can I do that with template and macro for example.

I tried different things but I didn't find solution.

Thanks in advance

madj, did you ever find a solution to this issue?

I also want to know how to set the internet bandwidth to reach 80% and 90% to trigger the warning, thank you.

For my router, I do 100 x the number of bytes received on the interface I want divided by the number of Mbps of my connection with a speedtest.

This gives for downloads bandwith :

100*last(//net.if.in[ifInOctets.111])/{$DOWNLOAD}
100*last(//net.if.in[ifInOctets.111])/2000000000 (2 Gbps)

This gives me the percentage of usage of my downloaded bandwidth compared to the max of my connection.



Of course, my net.if.in is already transformed to bps beforehand.

On the other hand, I created my own elements and I did not use a template.

hi Cloudeuw,
Can you please provide an example of the trigger?
thank you
