Your Minimum Monitoring Configuration

The minimum performance objects to monitor are those corresponding to the main hardware resources of your system: memory, processors, disks, and network components. Table 5.7 lists the appropriate counters and the categories of information they provide.

Table 5.7 Monitoring the Minimum Objects


Component
Performance aspect being monitored
Counters to monitor
Disk Usage LogicalDisk\% Free Space

LogicalDisk\% Disk Time

PhysicalDisk\Disk Reads/sec

PhysicalDisk\Disk Writes/sec

Use diskperf -y to enable disk counters and diskperf -n to disable them. To specify the type of counters you want to activate, include d for physical disk drives and v for logical disk drives or storage volumes. When the operating system starts up, it automatically sets the diskperf command with the -yd switch to activate physical disk counters. Type diskperf -yv to activate logical disk counters. For more information about using the diskperf command, type diskperf -? at the command prompt.

The % Disk Time counter must be interpreted carefully. Because the _Total instance of this counter might not accurately reflect utilization on multiple-disk systems, it is important to use the % Idle Time counter as well. Note that these counters cannot display a value exceeding 100 percent.

For more information about disk performance counters, see "Examining and Tuning Disk Performance" in this book.

Disk Bottlenecks LogicalDisk\Avg. Disk Queue Length

PhysicalDisk\Avg. Disk Queue Length (all instances)

Memory Usage Memory\Available Bytes

Memory\Cache Bytes

You can also use Memory\Committed Bytes and Memory\Commit Limit to detect problems with virtual memory.

Memory Bottlenecks or leaks Memory\Pages/sec

Memory\Page Faults/sec

Memory\Pages Input/sec

Memory\Page Reads/sec

Memory\Transition Faults/sec

Memory\Pool Paged Bytes

Memory\Pool Nonpaged Bytes

Although not specifically Memory object counters, the following are also useful for memory analysis:

Paging File\% Usage Object (all instances)

Cache\Data Map Hits %

Server\Pool Paged Bytes and Server\Pool Nonpaged Bytes

Network Usage Network Segment: % Net Utilization

Note that you need to install the Network Packet Protocol driver for Network Monitor in order to use this counter.

Network Throughput Protocol transmission counters (varies with networking protocol); for TCP/IP:

Network Interface\Bytes total/sec

Network Interface\Packets/sec

Server\Bytes Total/sec or Server\Bytes Sent/sec and Server\Bytes Received/sec

You might want to monitor other objects for network and server throughput, as described in "Monitoring Network Performance" in this book..

Processor Usage Processor\% Processor Time (all instances)
  Bottlenecks System\Processor Queue Length (all instances)

Processor\Interrupts/sec

System\Context switches/sec


If you want to test the limits of your system as part of establishing a baseline, monitor the recommended counters during the following activities:

  • Adding base services
  • Adding connections
  • Running network applications
  • Opening a file
  • Printing a file
  • Copying or writing to a file
  • Accessing a database
  • Sending a message
