Description: Monitors legacy WebGraph thermo-hygrometer temperature and relative humidity sensor values and alarm thresholds.

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 WebGraph-OLD-Thermo-Hygrometer-US-MIB?

This is a proprietary MIB for a legacy WebGraph networked thermo-hygrometer appliance that measures ambient temperature and relative humidity, typically used for server room or rack environmental monitoring. It exposes hardware sensor readings via per-sensor tables covering both raw temperature values and a binary (threshold-crossed) temperature indicator, along with device session/configuration objects like a control password and configuration-mode flag. As an environmental monitoring device, its entire purpose is hardware status monitoring: current temperature and humidity readings and threshold-alarm states directly indicate whether the monitored environment, such as a data closet or equipment cabinet, is within safe operating range. It has no apparent dependency on other standard MIBs, being a small self-contained proprietary schema, and it is explicitly marked "OLD," indicating it is a superseded legacy version of the vendor's current thermo-hygrometer MIB. It is deployed on legacy WebGraph environmental sensor units placed in server rooms, telecom closets, or equipment cabinets for temperature/humidity monitoring. Engineers can download the WebGraph-OLD-Thermo-Hygrometer-US-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WebGraph-OLD-Thermo-Hygrometer-US-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

  • Wiesemann & Theis (W&T) Web-Thermo-Hygrometer networked environmental sensor

Monitoring Examples

An operator would poll wtWebGraphThermHygroSensorTable/wtWebGraphThermHygroSensorEntry to enumerate configured sensors by wtWebGraphThermHygroSensorNo, then read wtWebGraphThermHygroTempValueTable's wtWebGraphThermHygroTempValue for the current temperature on each sensor. A value crossing into the alarm state reported by wtWebGraphThermHygroBinaryTempValueTable's wtWebGraphThermHygroBinaryTempValue would flag that a monitored room or rack has exceeded its configured high-temperature threshold, signaling a possible HVAC failure.

What Can Be Monitored

  • current temperature reading per sensor
  • relative humidity reading per sensor
  • binary (threshold-crossed) temperature alarm state
  • sensor count/index
  • device session/config-mode status
