Bandwidth usage alerts

Is there a way to configure an alert that would email user if more than 5GigaBytes of data is transfered over his interface on a per month basis ?

I am interested in monitoring/alerting on the amount of data transfer rather than actual transfer rate.

Thanks.

Dave

I think you should use Traffic Monitor test.

You've misunderstood.

I want to alert on amount of data transfered.
Not on transfer rate.

I have usage limits for customers (5Gigabytes a month), but no speed limits.
Hoping to email alerts when they've reached their 5Gig limit on a monthly basis.

You may use SNMP Get test and the following OIDs:
1.3.6.1.2.1.2.2.1.10.<index> - ifInOctets. The total number of octets received on the interface, including framing characters.
1.3.6.1.2.1.2.2.1.16.<index> - ifOutOctets. The total number of octets transmitted out of the interface, including framing characters.
But question is: what if your client or somebody else resets the router?

Is there a way to send alert if x amount of octets are exceeded on a per month basis ?
ie. send email if >5G/mo

If you want alert on a per month basis, start test once a month.
But there is problem: ifInOctets, ifOutOctets SNMP counters are 32 bits counter, 5GB > 32 bits - this means standart counters will be reseted.
Check the manual on your router, it may provide additional counters
