W need a script and/or template designed to run via Cacti that allows us to set thresholds using values calculated via the Bytes/s + total bandwidth template included. The ultimate goal is to be able to send an alert to a specific email address when the combine total traffic_in and traffic_out for a given interface goes over a threshold we can set on an individual basis. The interfaces are being polled via snmp on a 1min interval with a 1mon rrd refresh time. Interfaces will all have unique names to limit confusion. The script needs to be able to handle a discovery refresh as the name/quantity of interface on a given host may change over time.
## Deliverables
I expect that there will be data and threshold templates for cacti provided. If required for calculation, additional scripts may need to be installed.
## Platform
Linux
