Select a device implementing ATMF-CES 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 locate atmfCESRetryTimer under the atmfCESActiveSvcEntry branch of ATMF-CES, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports, in seconds, how long until the device next retries establishing this circuit-emulation SVC connection. 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 timer has been counting down (non-zero) for an unusually long stretch of consecutive polls, which would suggest the SVC is repeatedly failing to connect. Click Finish to create the monitor; you can adjust any parameter later.
