What Is SARIAN-MONITOR-MIB?

SARIAN-MONITOR-MIB is a Digi International (Sarian Systems) vendor-specific MIB that monitors cellular/PPP router health across four functional groups: PPP interface status, GPRS/cellular radio state, system resource health, and configuration change tracking. Its sarianPPPTable (indexed by ifIndex) exposes pppDLTotalData, pppDLWarn, and pppDLStop Counter64 objects for tracking data-plan usage limits on each PPP link, while sarian-gprs scalars report gprsSignalStrength, gprsRegistered (roaming/denied/searching states), gprsAttached, and gprsNetworkTechnology (GPRS/EDGE/UMTS/HSDPA), plus CDMA-specific objects like cdmaEcio and cdmaPilotPN. System health is covered by cpuUtil/cpuMin/cpuMax/cpuAvg, temperature, and free-buffer counters (msgsFree, bufsFree, bigBufsFree), and sarian-config tracks changesSincePowerUp and unsavedChanges for auditing configuration drift. It depends on RFC1155-SMI for its enterprise OID placement and is deployed on Sarian/Digi cellular routers providing WAN connectivity in remote or mobile deployments, where field engineers rely on SARIAN-MONITOR-MIB SNMP monitoring to watch link quality and device health remotely.

IPNetwork Monitor allows you to monitor SNMP objects defined in SARIAN-MONITOR-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

Sarian Systems / Digi International cellular and WAN routers

Monitoring Examples

An operator polls gprsSignalStrength and gprsNetworkTechnology to confirm a cellular router has adequate coverage, then checks pppDLWarn/pppDLStop against pppDLTotalData to see how close the link is to its data cap; a rising temperature reading alongside a cpuMax spike near 100 would indicate the unit is under thermal or processing stress that could precede a WAN outage.

What Can Be Monitored

PPP data usage vs. warning/stop limits
GPRS/cellular signal strength and registration state
network technology (GPRS/EDGE/UMTS/HSDPA)
CPU utilization min/max/avg
device temperature and free buffer pools
unsaved configuration change counters
