Performance counters (counter) are some data metrics that describe the performance of a server or operating system. Counter plays a key role in performance testing, especially in analyzing the scalability of the system and locating the performance bottleneck, the analysis of the counter value is very important. However, it must be stated that a single performance counter can only reflect one aspect of system performance, and analysis of performance te

The previous article, "WMI for server Performance monitoring", describes how to get server performance through remote COM (also available locally), so this article mainly says that the Windows system comes with performance monitoring----->performancecouonter. Open Management Tools-- > Performance, we can immediately see the server's CPU, process run time, disk capacity and other performance parameters chart. However, more than just these, we can look at other performance metrics by adding a tech

involves the buffer Pool of SQL Server, an internal cache manager, It can be said that after SQL Server2012, all memory management is under the control of Max Server. At the same time, SQL Server in the process of running, the parameters of various memory will be recorded, which is very important for us to determine the memory pressure of SQL Server is of great reference significance Some of the counters mentioned below are stored in the Sys.dm_os_pe

query (or better) to get real-time unread message number. Better scenario: Set up a counterFirst, let's set up a new table to store the number of unread messages per user. Class Usernotificationscount (models. Model): "" " this model holds the number of unread messages per user" "" user_id = models. Integerfield (primary_key=true) Unread_count = models. Integerfield (default=0) def __str__ (self): return ' We provide each registered user with a corresponding Usernotificationscount rec

Object in Part 1 we looked at the counters object and what purpose it serves; We also examined its four methods. In this part we ' re going to look at the counters object in a bit more depth and look at some code to track the popularity of various search terms and code to display the values of all of the counters!

Unfortunately this component are only built for counting Page view hits. If we wanted to count something else, say all time a user entered a particular search query into our site ' s search page, We are hard pressed with using the PageCounter object. Fortunately Microsoft also provides

Memory: memory usage may be the most important factor in system performance. If the system frequently switches pages, the memory is insufficient. "Page Swap" is a unit called "page". It moves code and data blocks of a fixed size from Ram to a disk to release memory space. Although some page switches enable Windows 2000 to use more memory than actually, they are acceptable, but frequent page exchanges will reduce system performance. Reducing page switching significantly increases the system respo
