I'm looking for a way to alarm on data usage (total bytes transferred) instead of bandwidth usage (bytes per sec). Has anyone seen a probe or talked to Nimsoft about doing this?
The SNMP OIDs used by the interface_traffic probe actually contain the total bytes for each interface, not the per-second average. (They are knowns as ifInOctets and ifOutOctets.) The interface_traffic probe just does the math for you automatically. If you want the raw values, the easiest way to retrieve them would be the snmpget probe. And you can configure a threshold in the probe for those OIDs to generate an alarm on the total in or out bytes transferred.
Be wary as the counter can reset if the total Octet count exceeds the OID's storage capability.
