SQL Profiler is a very powerful tool. It is fine to read the analysis principles in order. However, if you want to analyze complicated situations, you need more things. Here we will introduce a method to operate Profiler Trace like an SQL table, so that you can use select to view the information you are interested in. To do this, you can use a built-in function named fn_trace_gettable. select * from fn_tra

Label:When programming with EF, sometimes we can't look at the SQL statements that EF eventually generates, and it doesn't parse the problem well. Let me explain the use of SQL Server Profiler. SQL Server Profiler can view the resulting SQL statements.First open Microsoft SQL server Management Studio, and then open the Tool->sql Server Profiler,If the application

large problem is divided into multiple thread block processing, each block of the number of threads is not too small, like this article only 1 threads, which is a huge waste of hardware resources. An ideal solution is to divide n thread blocks, each with 512 threads, to decompose the problem, often more efficiently than a single thread parallel processing or a single piece of parallel processing. This is also the essence of CUDA programming. The above analysis of the performance of the method

Project Address: Ruby-prof In the previous Profiling tool in Ruby, we listed several of the most commonly used profilers, but just a brief introduction, this time detailing how ruby-prof is used. Ruby-prof is a powerful, support CPU, memory use, object allocation and so on performance analysis, and provides a lot of friendly output format, not only have text-based, HTML format, but also output Graphviz format dot file, and applicable with Kcachegrind

In applications with large data volumes, you often need to optimize database configurations and SQL statements to ensure the concurrency of applications when loading large data volumes. MySQL built-in analyzer Profiler In applications with large data volumes, you often need to optimize database configurations and SQL statements to ensure the concurrency of applications when loading large data volumes.

function that has a larger overhead (CPU or memory GC Alloc), it's hard to see more detail as the effects of cross-language boundaries are blocked. A "normal" approach Since the API interface of Profiler is also exposed to the script, it is normal to turn to the corresponding Lua code according to the problematic calls on the C # side, read the relevant script logic, and add the corresponding profiling s

DebuggingProgramSometimes or some ides may not provide detailed database exception information. SQL Server Profiler is a graphical user interface for SQL tracking. It can monitor database engines and analysis services. When using LINQ to SQL or ADO. NET Entity Framework, you can use it to clearly understand the statements they have executed on the database. We can also use it to track database exceptions. SQL Server

A major advantage of SQL Server databases is the rich UI management and debugging tools, which is definitely better than Oracle and other large and medium-sized databases. Among the many tools of SQL Server, it is very important for developers and DBAs to use SQL profiler. Each action executed in SQL Server can be clearly viewed in SQL profiler, which is very helpful for performance tuning and later mai

Address: http://google-perftools.googlecode.com/svn/trunk/doc/cpuprofile.html The CPU profiler usage process consists of three steps: connecting to the application, running the code, and analyzing the output result. 1. link the library into the application To use CPU profiler during execution, you need to add the parameter-lprofiler during code link. You can also use ld_preload, e.g.%Env ld_preload = "/usr/

Recently I saw Lao Zhao blog "using profiler to analyze program performance" (http://www.cnblogs.com/JeffreyZhao/archive/2009/12/22/profiler-sampling.html ), It was mentioned that in order to solve the problem of failure to trace method calls within the framework, Lao Zhao introduced the method of tracing with Profiler. many of his friends did not use profilter i

. You do not know which command is used. Therefore, use another machine to open SQL Profiler and find a process in the Enterprise Manager to end it. Check what is executed in SQL Profiler. It was found that it was a statement like kill 85. OK, kill the process on the server, solve the problem, and check the Current Activity in the Enterprise Manager. There is no error.SQL

Tags: debug obj HTML one database combination LINQ technology logs. comRecent queries for data combinations of LINQ to Object and LINQ to entity require the use of SQL Server Profiler to detect statements executed on the data, which is a great help when debugging SQL statements. Here is a brief description of the features commonly used in the SQL Server Profiler usage process. (Reprinted from: http://www.cn

An important application scenario for SQL Server Profiler is to monitor the analysis deadlock.Here's an example to learn how profiler monitors deadlocks.1. Create test data to simulate deadlocks, create tables table_a and table_b , and insert test data.CREATE TABLEtable_a (IDint, Numint)CREATE TABLETable_b (IDint, Numint)INSERT intoTable_aVALUES(1, -)INSERT intoTable_aVALUES(2, -)INSERT intoTable_bVALUES

MongoDB's own profiler allows easy recording of all time-consuming operations for ease of tuning;First, start the profiler functionThere are two ways to turn on the Profier function:The first is to set it directly in the startup parameters, and add t

P6spy combined with SQL profiler Configuration P6spy is a dynamic monitoring framework for database access. It has been very mature for a long time. p6spy simulates a standard JDBC driver and acts as a proxy for the real underlying JDBC driver. That is to say, we only need to configure the JDBC driver used in the system as the p6spy driver, and configure the realdriver in the p6spy configuration as the actual JDBC driver, so that we can use its p

SQL Server Profiler is a performance monitoring tool for MS SQL. You can use this tool to find the SQL statements to be optimized, and then use the database engine optimization advisor tool to help optimize the database.

As a performance tool of the Microsoft SQL Server database series, SQL Server Profiler can track the running status of databases in real time and find slow queries or deadlocked SQL statements, to optimize the system. This article describes how to use Silverlight to monitor SQL Server Profiler in real time (the database environment uses SQL Server 2005 as an example) First, let's take a look at the SQL Ser
