Description: Monitors Zhone Technologies device system resources including CPU utilization, memory usage, and uptime.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ZHNSYSMON?

This is a Zhone Technologies enterprise MIB providing a general System Monitoring function used across Zhone's broadband access and DSL/PON platform family. It exposes an alarm table and a diagnostic test table, capturing alarm type, severity, and the interface an alarm applies to, alongside self-test type and result status per interface. It is explicitly a hardware/software health-monitoring MIB: it lets an operator see active alarms with severity and a human-readable description, and the results of on-demand or scheduled diagnostic tests against specific interfaces, functioning like a generalized fault/status subsystem covering the device's overall operational health. It works alongside Zhone's chassis and interface MIBs, using interface names to correlate alarms/tests to specific hardware ports. It is deployed on Zhone Technologies access/DSL/PON systems in service-provider and enterprise access networks, where ZHNSYSMON SNMP monitoring supports proactive fault detection across alarms and diagnostic tests.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZHNSYSMON. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An administrator would walk zhnSysMonAlarmTable and inspect each zhnSysMonAlarmEntry for zhnSysMonAlarmType, zhnSysMonAlarmSeverity, and zhnSysMonAlarmInterfaceName to identify which interface is raising a critical alarm and read zhnSysMonAlarmDescription for details. Separately, polling zhnSysMonTestTable/zhnSysMonTestEntry shows zhnSysMonTestType and zhnSysMonTestRowStatus per zhnSysMonTestInterfaceName, revealing whether a diagnostic loopback or self-test on a given port passed or failed. A persistent high-severity alarm entry combined with a failed test result on the same interface would point to a genuine hardware fault rather than a transient condition.

How to Use in IPNetwork Monitor

Example using zhnSysMonAlarmType OID:

Select a Zhone Technologies access/DSL/PON system (alarm-severity/diagnostic-test-result 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 zhnSysMonAlarmType into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The type of alarm currently posted. 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 a value appears here at all, since every defined value in this object represents an active alarm condition rather than a normal state. Click Finish to create the monitor; you can adjust any parameter later.
