What Is ROOMALERTST4E-MIB?

ROOMALERTST4E-MIB is a vendor-specific MIB from AVTECH Software for the Room Alert ST4E environmental monitoring appliance, registered under AVTECH's enterprise OID 20916. Its sensors subtree exposes internal-tempf/internal-tempc, internal-humidity, and internal-heat-index scalars (each an integer scaled by 100 to work around SNMP's lack of floating-point support), plus digital-sen1/digital-sen2 four-value groups that report either temperature/humidity/heat-index readings or current/power/voltage/reference values depending on which external digital sensor is attached, and a switch-sen1 object for a dry-contact digital switch input. A signaltower subtree exposes read-write LED/alarm outputs (red-led, amber-led, green-led, blue-led, white-led, alarm1, alarm2) for driving a physical signal tower, and a room-alert-st4e-snmp-trap notification carries alarmmessage text when any monitored condition crosses a threshold. This makes it a compact environmental-sensor-and-alerting MIB purpose-built for rack/room temperature, humidity, and dry-contact monitoring rather than a general device-management MIB. The ROOMALERTST4E-MIB MIB is deployed on AVTECH Room Alert ST4E appliances in data centers and equipment rooms to catch cooling failures before they cause hardware damage.

IPNetwork Monitor allows you to monitor SNMP objects defined in ROOMALERTST4E-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.

Monitoring Examples

An operator polls internal-tempf and internal-humidity every few minutes and divides by 100 to get real-world values; a rapid rise in internal-tempf alongside a room-alert-st4e-snmp-trap carrying an alarmmessage referencing temperature would indicate a rack cooling failure in progress.

What Can Be Monitored

internal temperature (F/C) and humidity readings
heat index reading
external digital sensor readings (temp/humidity/power)
dry-contact switch sensor state
signal tower LED/alarm output state
