Windows Server performance monitoring tools, methods, and key metrics

Monitoring methods

Recommended Use Windows The "Performance Monitor" that comes with the old version of the Windows called performance counters) to monitor the performance of the server.

Open the Management tool in Control Panel, open Performance Monitor in the management tool, the following interface (each version of the window The operating system's performance Monitor may have a slightly different interface ):

Key indicators

CPU Monitoring

Processor time

Address

\processor (_total) \% Idle Tile

Describe

% Processor time refers to the percentage of time that the processor uses to perform non-idle threads. It is calculated by measuring the time that the processor uses to execute idle threads, and then subtracting the value with 100%. ( Each processor has an idle thread that consumes cycles when no other thread can run ). This counter is the primary indicator of processor activity, showing the average percentage of busy times observed during the sampling interval. It should be noted that the calculation of whether the processor is idle is performed during the internal sampling interval of the system clock (10ms) . Given that the processor is now very fast, the% Processor time will underestimate processor utilization when the processor may be serving a thread between the system clock sampling interval for a significant amount of times . A workload-based timer application is an example of the more likely to make an inaccurate measurement of the application when it signals the timer exactly after sampling.

Recommended indicators

the monitoring content should not exceed 80%

Description

High Description CPU resources are about to be exhausted and should be increased CPU resources or implement a distributed policy

Memory monitoring

Available Mbytes

Address

\Memory\Available MBytes

Describe

Available MBytes refers to the amount of physical memory that can be allocated to a process or system immediately to MB expressed as units. It is equal to the sum of memory allocated to the standby ( cached ), Idle, and 0 paged list.

Recommended indicators

This value should not be less than -

generally want to keep 10% available memory, assuming that the system has 8G memory, it is best not to lower the value -

Description

Too high to indicate that memory resources are about to be exhausted, consider increasing memory

Pages/sec

Address

\memory\pages/sec

Describe

pages/sec refers to the speed at which a hard page error is read from or written to disk. This counter is the primary indicator that can display system-wide delay type errors. It is the sum of memory\\pages input/sec and memory\\pages output/sec . is calculated using the number of pages, so that it can be compared with other page counts, such as memory\\page faults/sec , without having to do the conversion , which includes the file system cache to satisfy the error ( typically requested by the application The page is retrieved in a non-cached mapped memory file.

Recommended indicators

This value should not exceed -

Description

This value is too high, indicating that there are many things in memory that need to be exchanged with the hard disk, should consider increasing memory or replacing memory

Disk Monitoring

Disk time

Address

\physicaldisk (_total) \% Disk time

Describe

Disk Time Refers to the percentage of time that the selected disk drive is busy servicing a read or write request.

Recommended indicators

This value is not suitable for more than Ten

Description

This value is too high to indicate that the hard drive is less responsive and should be swapped with a higher performance drive

ASP Monitoring

Request Wait Time

Address

\asp.net\request Wait Time

Describe

The number of milliseconds that the most recent request has been waiting in the queue.

Recommended indicators

This value is not suitable for more than 10000

Description

This value is too high to indicate IIS already unable to withstand more requests, consider implementing a distributed strategy
