perfmon counters

The simplest ASP. NET performance monitoring tool is the performance counter: Run, enter perfmon, you can open the system's built-in Performance Monitor, you can add performance counters. Performance object Performance counters ASP. NET Application Restarts ASP. NET Requests Queued ASP. NET Worker Process Restarts

Heap sizeThe sum of all types, that is, the space occupied by the entire managed heap # Gen 0 Collections The number of times that the Garbage Collector recycles Gen 0 objects after the system is enabled # Gen 1 Collections Number of times the Garbage Collector recycles the Gen 1 object since the system is enabled # Gen 2 Collections Number of times the Garbage Collector recycles the Gen 2 object since the system is enabled A

When monitoring disk performance, the primary measure (metric) is IO latency, which is the time delay in creating an IO request from application to disk to complete the IO request. SQL Server is prone to performance problems if the physical disk does not complete the IO request i

listing all the running processes on the system, this parameter narrows PsList ' s scan to tthe process That has the specified PID. Thus:PsList 53Would dump statistics for the process with the PID 53. How it WorksLike Windows nt/2k ' s built-in PerfMon monitoring tool, PsList uses the Windows nt/2k performance counters to OBTA In the information it displays. You can find documentation for Windows

Label:The IO performance of SQL Server is affected by the IO latency of the physical disk and the IO operations performed internally by SQL Server. When monitoring disk performance, the primary measure (metric) is IO latency, which is the time delay in creating an IO request from application to disk to complete the IO request. SQL Server is prone to performance problems if the physical disk does not complete the IO request in a timely manner, keeping up with the speed of the request payload. SQL

that you must have the "Locked Pages in Memory" permission to use the AWE API. Therefore, if you use the sp_configure option on a 32-bit system to enable the "awe enabled" feature, but "Locked Pages in Memory" is not set, this command will fail.(Here, it seems that some answers are not correct. The question is how the 64-bit system answers the question to 32-bit... Or I don't really understand it) 3. Why does the Task Manager show all memory allocated to SQL Server? You may encounter the follow

. You can add multiple stress functions and the number of people following them is the number of persons under pressure required by this stress function. 7. Set the network. This option works when stress testing is closely related to the quality of the network. 8. performance counters. You can add related counters in perfmon. This article does not

. Although the request per second counter is included in was by default, you may want to add other counters. You can click the perf counters icon and add counter to add other counters. A particularly useful counter is ASP requests queued, which is often the key to identifying a blocked or long-lived page or component. Resources for analyzing ASP performance inclu

I. Error targeting:Two configuration settings affect how error information is displayed: 1. custom errors mode-this setting enables or disables custom errors. when custom errors mode is enabled, errors on a page are hidden. this setting has three possible values: On, off, And remoteonly.When you are redirected to a page with custom errors, a query string variable is automatically passed to the error page. the query string variable, named aspxerrorpath, contains the path of the page that was or

memory in Task Manager is gradually rising (and possibly suddenly). When you suspect that the application has a memory leak, you must first determine which type of memory is leaking so that you focus the debugging effort on the appropriate area. Use PerfMon to check the following performance counters for applications: Process/private Bytes,. NET CLR memory/# Bytes in all heaps and. NET CLR locksandthreads/

As a result of monitoring and reporting needs, statistical performance counter daily values, to confirm the health of the database server. If open counter to fill in, more trouble, now statistics with PowerShell to read the value of the counter. Phase I: Powershell read the counter file and count the values of one of the counters $startDate = (get-date). AddDays (-1). Date $endDate = (get-date). Date $perfPath = "D:\DATAFILES\

per Second is a key value that requires in-depth analysis. The higher the value, the better. Typically, if you can't determine a specific goal from the use of reports and budgets, you can have the ASP's requests per second value above 30, of course the ASP is not connected to the database or uses other components. Because it can be foreseen, connecting to the database will add to the burden of the program.Although there are request per second This counter is included by default in was, you may

Hello everyone, I am very happy to meet you again. What do we bring to you today? You may have noticed the title, which is a system tool that we will ignore. Why did I introduce this tool to you? It was because one of my experiences showed me the value of this tool. A few days ago, the computer often experienced slow and slow responses, however, I feel that it is not a hardware problem, and the running program should not occupy too much resources. If I want to think about it and don't know why,
