Alarm for a pre-determined threshold of Bandwidth?

[TBT]

Is there a way to trigger an alarm when a switches bandwidth drops below a per-determined threshold (Kind of like the inverse of a bandwidth threshold alarm).
I have a multicast feed coming into a switch interface that should steadily be at approximately 800 mbps and I would like to be able to monitor the interface and see an alarm if the bandwidth drops below 750 mbps (for example).

Please advise.

I'm not sure what plugin you are using to check bandwidth (if you're using the wizard or not) but the standard nagios-plugin style thresholds are supposed to be able to accept a range using : in the warning or critical value. An example of this is:

-w 750:900 (less than 750 and over 900)

More information can be found here: https://nagios-plugins.org/doc/guidelin ... HOLDFORMAT however not all plugins conform to these standards so depending on the plugin you are using it may or may not work.

Exactly what I was looking for.

Thank you.
