Category: Windows and Enterprise Performance

Description: Tracks performance counters on Windows NT systems, covering CPU, memory, disk I/O, and per-process 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?

WINDOWS-NT-PERFORMANCE is a Microsoft-originated MIB that exposes the Windows NT/Server SNMP agent's mapping of the OS's native Performance Monitor counter set. It surfaces system performance data including processor (CPU) utilization, memory usage, disk I/O throughput and queue length, and process/thread counts for the host. It is explicitly used to monitor the hardware and software status of a Windows server, mirroring what Task Manager or Perfmon would show for CPU load, memory pressure, and disk activity without requiring native WMI/RPC access. It depends on the Windows SNMP service's Performance Counter extension agent, which maps directly onto the OS's internal performance-counter registry, making it a Microsoft-specific analog to the vendor-neutral HOST-RESOURCES-MIB. It is deployed on legacy Windows NT/2000/Server hosts with the SNMP service enabled, letting cross-platform network management systems poll CPU, memory, and disk metrics from a mixed-vendor monitoring console. Network engineers evaluating or troubleshooting this functionality can download the WINDOWS-NT-PERFORMANCE file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WINDOWS-NT-PERFORMANCE. 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 NT/Server host running the Microsoft SNMP service

Monitoring Examples

No concrete object names were supplied for this MIB in this batch, but consistent with its Performance Monitor lineage it would expose counters such as processor time, memory available bytes, and physical/logical disk queue length. An admin would poll the processor-time counter and see it trend toward 100% during a runaway process, or watch the memory available-bytes counter fall steadily, signaling memory pressure on the server. A rising disk queue-length counter would likewise indicate the disk subsystem is becoming a bottleneck.

What Can Be Monitored

  • CPU/processor utilization
  • memory usage/availability
  • disk I/O throughput and queue length
  • process/thread counts
