How to modify bandwidth usage trigger

[syman888]

Hi everybody,

I am using Zabbix version 5. I want to add a trigger to the "Template Module Interfaces SNMP" template, which will trigger a warning notification when the total bandwidth usage of my network reaches 80%. How do I modify this trigger? Because this original trigger is "The network interface utilization is close to its estimated maximum bandwidth."


Default Trigger

Name：Interface br-network1(br-network1): High bandwidth usage (>{$IF.UTIL.MAX:"br-network1"}%)

Operational data：In: {ITEM.LASTVALUE1}, out: {ITEM.LASTVALUE3}, speed: {ITEM.LASTVALUE2}

Problem expression：({DaYa SD-WAN:net.if.in[ifHCInOctets.16777219].avg(15m)}>({$IF.UTIL.MAX:"br-network1"}/100)*{DaYa SD-WAN:net.if.speed[ifHighSpeed.16777219].last()} or
{DaYa SD-WAN:net.if.out[ifHCOutOctets.16777219].avg(15m)}>({$IF.UTIL.MAX:"br-network1"}/100)*{DaYa SD-WAN:net.if.speed[ifHighSpeed.16777219].last()}) and
{DaYa SD-WAN:net.if.speed[ifHighSpeed.16777219].last()}>0

Recovery expression：{DaYa SD-WAN:net.if.in[ifHCInOctets.16777219].avg(15m)}<(({$IF.UTIL.MAX:"br-network1"}-3)/100)*{DaYa SD-WAN:net.if.speed[ifHighSpeed.16777219].last()} and
{DaYa SD-WAN:net.if.out[ifHCOutOctets.16777219].avg(15m)}<(({$IF.UTIL.MAX:"br-network1"}-3)/100)*{DaYa SD-WAN:net.if.speed[ifHighSpeed.16777219].last()}


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

there are ways of attaining high bandwidth without buying unnecessary hardware and driving up your costs. In this piece, I’ll examine how bandwidth is measured, how to check bandwidth, and how to increase bandwidth.

Thank you very much, waiting for the results of your research, thank you!
