High bandwidth usage

[Kirin2]

Hi,

Is this trigger "Network Interfaces Discovery: Interface NAME: High bandwidth usage > {$IF_UTIL_MAX:"NAME"}%" is shown when usage of internet(in or out) by this interface higher than % ?
If yes, how can I find the value $IF_UTIL_MAX:"NAME" ? OR better, how can I change this value on 80%

{$IF_UTIL_MAX} should be set in the macros.
Open the host or template and check the Macros tab.
If it is not displayed, try pressing the "Inherited and template macros" button.

Please check the manual for macro {$IF_UTIL_MAX:"{#IFNAME}"}.
If the corresponding macro is not registered, {$IF_UTIL_MAX} should be used.

Template macros can be overwritten with host macros.
If you want to change the value only for a specific interface, you can determine the fault according to the interface without changing the conditional expression by registering the macro specified up to the interface with the host macro.

Hi kirin2/Atsushi

Could you tell me how to make a reference line in the BW graphs to show when the consumption exceeds 80% of the total bandwidth. And if it is possible to send alerts.
At the moment I have only managed to set the amount of BW of my link.

How to set, refer to the network traffic line of the bandwidth chart, when the network bandwidth exceeds 80% and 90% of the total bandwidth, the trigger condition will send an alarm, thank you.
