Interface Errors and/or High utilization verification

Question

I am trying to get an NQE scheduled to run every 5 mins. and fetch if an interface has any errors and/or if the interface utilization is high ( >90%).

With the below NQE i get an error as below - Any fields with bytes is not recognized..

ERROR: Record does not have field: "bytesOut".


interfaceUtilization(iface) = 100 * (sum(iface.bytesOut) - sum(iface.bytesIn)) / (sum(iface.bytesOut) + sum(iface.bytesIn));
foreach device in network.devices
foreach interface in device.interfaces
where interface.adminStatus == AdminStatus.UP
select {
  deviceName: device.name,
  interfaceName: interface.name,
  utilization: interfaceUtilization(interface)
}

Not sure why “bytes” is not recognized by the NQE
How to have this scheduled to run every 5 mins ?

@venkat rajMaybe there is a misunderstanding here. The NQE queries run against snapshot data. Which means if you want the NQE query to be “run every 5 minutes” it means you would need to take a snapshot every 5 minutes. You could probably achieve this with a subset of devices in a “workspace network”. Most likely the Full network would not be able to run every 5 minutes.What you are trying to do is more like our “Performance Data” feature.https://docs.fwd.app/latest/application/device_performance/That is based on SNMP collections that can be run independently of a snapshot collection.Another comment on “bytesOut”. We don’t parse the interface stats onto the data model. You would need to use the state file parsing to parse out that data.
