I am looking to proactively have an alarm when a cable modem has an problem, before the customer can call in to let us know. We are using Arris, Motorola, Hitron and Scientific Atlanta modems.
I would think the devices would have to support SNMP to get information about alerts into NPM. Otherwise you might be stuck with simple ping tests. If they support logging (and sending of logs) you could send the logs over to LEM.
You can monitor it as
and create an alert for when he's down.
Thanks for the information. I will setup a test
Are you the cable internet provider? If not, do you have the SNMP creds to the cable modems? You can certainly get more information from a cable modem with SNMP, such as SNR performance and throughput.
