Trigger configuration

[stepassia]

Hi, I've created this new item on Template Module HOST-RESOURCES-MIB SNMPv2 Template to display free memory in Mb:

Key: vm.memory.free[memoryFreeAbsolute.1]
Expression: (last(vm.memory.units.total[hrStorageSize.1])*last(vm.memory.units[hrStorageAllocationUnits.1]))-(last(vm.memory.units.used[hrStorageUsed.1])*last(vm.memory.units[hrStorageAllocationUnits.1]))
Units: B

The item display value correctly (eg. last value: 47.34 MB)

Then, I've created a trigger on this item:
Expression: {Template Module HOST-RESOURCES-MIB SNMPv2:vm.memory.free[memoryFreeAbsolute.1].avg(5m)}<200

The value is under 50Mb for more than 10 minutes but the triggers don't fire. Why? Thanks

Hi,
according to your units the trigger will fire up if your memory is under 200B. You should create your trigger with <200000000
