perfmon counters

"Disclaimer: This blog post is reproduced from http://www.cnblogs.com/ljhdo/p/5149401.html"The most recent work has been to deal with the SQL Server database, which requires a more comprehensive understanding of SQL Server. So also in the urgent to read the data, learning this classic relational database.Performance counters (performance Counter) are a numerical value that quantifies the state or activity of a system, and Windows Performance Monitor a

Windows performance monitor Overview Windows performance monitor is a Microsoft Management Console (MMC) management unit that provides tools for analyzing system performance. Monitors applications in real time only from a single consoleProgramAnd hardware performance, custom data to be collected in logs, define thresholds for alarms and automatic operations, generate reports, and view performance data in various ways. Start Windows Performance Monitor: start --> Run-> enter

Current connection System Total processor time Context conversion per second System calls per second Processor (0)(Each processor) DPC speed Number of interruptions per second DPC queues per second The results in the performance counter must be written into a special result file, testname. PRF (testname is the name of the test ). This is a text file separated by commas

is a text file separated by commas (,). It can be read in any standard text editor or used as input to workbooks or databases. However, this file cannot be read directly using PerfMon. This file contains the header information (number of counters, machine name, start time of naming), column header, and a table containing collected performance data. For the complete syntax and usage of this file, refer to t

During Game Development, the performance of the same type of games will always be compared. Generally, nvperfhud can only be used to analyze the applications we write.ProgramBecause this involves modifyingCode. So how can we analyze other people's games? We can use the counters provided by NVIDIA perfkit and the system management tools perfmon and DX pix for window for monitoring. Procedure: 1. install

Io subsystem counters in Performance Monitor Enter "perfmon" in the operation and use the performance monitor to observe the current I/O performance and determine whether I/O problems exist. On SQL Server, counters involving I/O are:Average read Bytes/sec, average number of bytes read per secondAverage write Bytes/sec, average number of bytes written per secondRe

process type. The instance name is the name of the process you serve (without a suffix)For descriptions of other counters, open the perfmon tool to view the instructions of each counter one by one.The code for getting a counter value of a machine is as follows:　 Public class perfcounter{Public perfcounter (string categoryname,String countername,String InstanceName,String machinename){This. categoryname = c

For normal testing, you often need to look at the data in Performance Monitor and now teach you how to turn on Performance Monitor: 1. Start-run (or press Win+r to open the Run dialog box) 2, input "Perfmon", and then enter Run window You can go to Performance Monitor, as shown in the figure: Performance Monitor Windows Performance Monitor uses performance counters, event trace data, and con

transactions. If transactions is very long, this wait type can start building up because of the other waiting transactions. Keep the transactions small. Serialization isolation can build up this wait type. If the is a acceptable isolation for your business, this wait type may be natural. The default isolation of SQL Server is ' Read Committed '. One of my clients have changed their isolation to "Read uncommitted". I strongly discourage the use of this because this would probably leads to ha

practical way to get started is to use the basic list and add the necessary related counters in the iteration. In addition, it is possible to capture and visualize performance counters in real time using Perfmon. In many cases, it is also possible to integrate user-defined metrics or plug-ins with APM tools. SQL Tools Because of the widespread use of databases i

Server farms by observing users' behaviors in the system and actively formulating countermeasures. Through reconfiguration and lock prevention, you can ensure that the improper behavior of a single user does not affect the experience of other users. For example, experienced terminal server administrators configure performance alarms to be notified when processor utilization increases and remains very high. This behavior usually indicates that a process occupies the processor exclusively, or a u

virtual memory to force the system to use faster memory. In fact, this is not wise. The so-called everything should not be done too absolutely, and it will not work if there is no virtual memory at all. The reason is that many applications require virtual memory to be used during design. If they are not used, the system may be unstable or the system will crash. For systems with small memory, such as 256 MB, the ratio is the most stable according to the ratio of 1.5 times and 3 times. That is,

you don't want to use C ++ attributes, there are corresponding classes and macros that you can use instead. you shoshould also be aware that setting counters to specific values is generally safe without having to worry about thread synchronization, but specify Ming calculations on the counters, such as incrementing or decrementing, requires the use of atomic operations such as interlockedincrement or synch

You can use Windows performance monitor to check in real time how running programs affect computer performance and collect log data for future analysis.During the testing process, you often need to view the data in the "Performance Monitor". Now you can enable the "Performance Monitor" method:1. Start-run (or press win + R to open the run dialog box) 2. Enter "perfmon" and press Enter. You can go to the Performance Monitor ", Windows performance mon
