    Trigger for power value

    Small problem configuring trigger. I am getting power values for the device like -25dbm, -19dbm. My problem is i have to set trigger when power goes under -8dbm or above -26dbm.

    I have set trigger like this ({ZTE-C320-GPON-noron.onu.1.1.1.[{#SNMPINDEX}].last()}<-8)or({ZTE-C320-GPON-noron.onu.1.1.1.[{#SNMPINDEX}].last()}>-26) but i am not getting result as i want. Please help me with this small issue guys.

      I guess that is the opposite since you're working with negative values:
      What your trigger is actually doing is to trigger if your last value is less than -8 (-9,-10,-11,...,-25) or greater than -26 (-25,-24...0, 1, 2) so it should trigger a lot.

      Code:
      ({ZTE-C320-GPON-noron.onu.1.1.1.[{#SNMPINDEX}].last()}>-8)or({ZTE-C320-GPON-noron.onu.1.1.1.[{#SNMPINDEX}].last()}<-26)
      I am not sure if this solves your problem, but from what I see it seems like this.

                Wrap everything on () and then put an and clause with the other condition

                          Maybe you can use filters to discard the rest

                              can't i specify in discovery rule? you know i am doing to discover ports in my genexis OLT. I want to learn it dynamically because whenever new ONU is added it will discover automatically.

                              You could create a custom discovery script
