WINDOWS-NT-PERFORMANCE-EXCHANGE

All MIBs › WINDOWS-NT-PERFORMANCE-EXCHANGE

Category: Windows and Enterprise Performance

Description: Monitors Microsoft Exchange Server performance metrics on Windows NT platforms including message queues and transport statistics.

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 WINDOWS-NT-PERFORMANCE-EXCHANGE?

WINDOWS-NT-PERFORMANCE-EXCHANGE is a MIB module that exposes Microsoft Exchange Server performance counters as collected via the Windows NT/Windows performance monitoring subsystem, mapped into SNMP for remote polling. It covers Exchange-specific performance data such as message queue depths and transport/delivery statistics rather than generic OS metrics. Its monitoring purpose is entirely software-performance oriented: tracking mail transport health, queue backlogs, and message throughput as key indicators that the Exchange messaging service is functioning normally versus experiencing delivery delays or overload. It implicitly depends on the broader Windows NT SNMP performance-counter mapping framework used across the WINDOWS-NT-PERFORMANCE-* family of MIBs. It is deployed on Windows servers running Microsoft Exchange Server in enterprise email environments where SNMP-based monitoring is preferred alongside or instead of native Windows performance monitoring tools. Engineers can download the WINDOWS-NT-PERFORMANCE-EXCHANGE file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WINDOWS-NT-PERFORMANCE-EXCHANGE. 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

Windows server running Microsoft Exchange Server

Monitoring Examples

No sample object or table names were extracted for this module and no module description text was available, so specific object identifiers cannot be cited; conceptually an administrator would poll Exchange message queue length and transport throughput counters to detect a mail queue backlog indicating a delivery bottleneck or a downstream connectivity problem. Without a verified object list, further technical specifics would not be grounded in the actual MIB content.

What Can Be Monitored

message queue depth
mail transport statistics
message delivery throughput
Exchange service performance
