Description: Manages ADH Networks remote access equipment, providing port configuration, session status, and dial-up connectivity objects.

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 ADH-NETCOM-MIB?

Despite its short_desc suggesting ADH Networks remote access equipment, the module description and sample objects instead indicate this MIB is actually structured for Environmental Technology Inc. SNMP-managed devices, likely environmental monitoring/alarm units (such as compressor or pressure monitoring controllers) rather than a dial/remote-access router. It exposes status objects like pressure, temperature, duty cycle, alarms, and compressor run-hours alongside configurable alarm thresholds. Its monitoring value is squarely environmental/hardware status monitoring — tracking pressure (PSI), temperature, compressor duty cycle and run-time hours, and alarm conditions against configured upper/lower limits, which is the equivalent of environmental sensor and equipment-health monitoring for this device class. It appears to be a self-contained proprietary MIB without an obvious dependency on standard IETF MIBs. It would be deployed wherever this device (e.g., a refrigeration/compressor or environmental control unit) needs remote SNMP-based alarm and status monitoring. Network engineers evaluating or troubleshooting this functionality can download the ADH-NETCOM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ADH-NETCOM-MIB. 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.

Supported Devices

environmental/compressor monitoring controller (Environmental Technology Inc. device)

Monitoring Examples

Sample objects such as pressurePSI, temperature, dutycycle, compressorHours, majorState, cycleTime, lowerLimit, upperLimit, and lowerAlarmLimit indicate an environmental/compressor monitoring scheme. An administrator would poll temperature and pressurePSI against their configured lowerLimit/upperLimit and lowerAlarmLimit thresholds to detect an out-of-range condition, and check compressorHours and cycleTime to track equipment wear and duty cycle, revealing an aging or overworked compressor before failure. The alarms object would summarize active alarm conditions for quick health assessment.

How to Use in IPNetwork Monitor

Example using majorState OID:

Select an Environmental Technology Inc. compressor/environment controller 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 majorState into the Find box to locate it in the OID tree, then select it and click OK. It reports the major state of the dehydrator. Online: currently pressurizing. 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 is 'leaky', since that means the dehydrator has shut down because it's unable to pressurize. Click Finish to create the monitor; you can adjust any parameter later.
