Select a Motorola/Cambium Canopy PLV subscriber modem, fixed wireless broadband CPE (firmware/bootloader upgrade-status status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type modemInfoDeviceUpgradeStatus into the Find box to locate it in the OID tree, then select it and click OK. This object indicates the Modems last Software Upgrade Status. 1 - Upgrade not started 2 - Upgrade in progress 3 - Last Upgrade failed 4 - Last Upgrade was successful. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value becomes 'failed', since that indicates the modem's last software upgrade attempt did not complete successfully. Click Finish to create the monitor; you can adjust any parameter later.
