    Network Interface Flapping

    Hi,

    I have been trying to solve the flapping monitoring in my dashboard, i have read and seen many video and im sure im close but still cant make it to work.
    I'm french maybe i missing a little comprehension but this is an example of what im trying to accomplish.

    some interface keep flapping because mostly of bad cabling or others issues , flapping can occur every minute or two.

    The recovery expression that im trying to accomplish is in a human language :

    recover only if my interface is not down after 5 minutes :


    My trigger expression is like this :

    {$IFCONTROL:"{#IFNAME}"}=1 and ({Template Module Interfaces SNMP:net.if.status[ifOperStatus.{#SNMPINDEX}].last()}=2 and {Template Module Interfaces SNMP:net.if.status[ifOperStatus.{#SNMPINDEX}].diff()}=1)

    And my recovery expression is :

    {Template Module Interfaces SNMP:net.if.status[ifOperStatus.{#SNMPINDEX}].min(5)}<>2

    so if my understanding is good i wrote it this way :
    if template X trigger items is not equal to down after 5 minutes you can recover it.

    Thank you in advance for your help or any advices
