SQL Monitor Tools

SQL Monitor 

SQL Monitor Tools can produce the best performance and resolve the least downtime. Ignoring server monitoring may cause the server to fall and cause a lot of money for the organization. Using SQL Server monitoring tools is the only way to protect your server against expensive system failures.

A good SQL Server monitoring plan can help you stay informed of:

• Performance: Decide if performance improvement is needed. For example, by saving a query completion time record, you can see the bottom field and make possible improvements. Checking the time when the queries are executed can cause problems that need to be fixed.

• Growth: Observe requirements for users and traffic. Database usage needs tend to develop faster than expected.

• Safety: Ensure adequate safety precautions are taken.

What Should I Watch?

SQL Server performance monitoring revolves around 4 main fields (and related counters):

• Physical Disk:% Disk Time: This counter monitors the length of time that the disk is busy with read / write activity. If a Physical Disk:% Disk Scheduler is close to 90% or greater than 90%, this indicates that too many system requests are waiting for disk access (this is Physical counter: check through Current Disk Sequence Counter). The number of pending I / O requests should not be greater than 1.5 to 2 times the number of physical disk shafts.

• Physical Disks: Average Disk Queue Length: the number of pending I / O operations (again, 1.5 or more times the number of disk bits is bad)

• SQL Server Buffer Manager - read / second page and write / second page. If this counter goes above your baseline, this may indicate the need for more hardware power

• Processor:% Processor time: 80-90% of continuous very high. Multiprocessor systems have separate instances for each CPU.

• Processor:% Custom time: Shows the time spent in Windows kernel commands (SQL Server I / O requests). If this Disk and Physical counter is high, faster disks or lower loads may be required for this server.

• Processor:% user time:% of CPU time spent on user operations (SQL Monitor Tools Server)

• Processor: Row Length: Number of threads waiting for the processor time. A higher number may indicate the need for faster or more processors.

• Memory: Available MB: indicates how much memory is available for the new process.

• Memory: Page / second: this counter shows how many times virtual memory has been accessed. The general rule says it should be less than 20. Higher numbers may mean excessive calls. Using Memory: A page / second error can then indicate whether SQL Monitor Tools Server or any other process is causing it.

SQL Server Monitor

SQL Server works with objects and counters, each object consists of one or more counters. For example, SQL Server Locks objects Say Deadlocks / sec Number or Lock Timeouts / sec. Access Method - Full scan / second: higher numbers (> 1 or 2) may mean that you are not using the directory and have switched to browsing tables instead.

Buffer Manager - Buffer Cache hit ratio: This is the percentage of requests offered by the data cache. When the cache is used correctly, it should be more than 90%. The counter can be increased by adding more RAM. Memory Manager - Target Memory Server (KB): Indicates how much memory SQL Server wants. If this is the same as SQL Server: Memory Manager - Total Server Memory (KB) counter, you know that SQL Server has all the required memory.

Memory Manager - Total Server Memory (KB): Too much memory really used by SQL Server. If this is the same with SQL Server: Memory Manager - Destination Server Memory (KB), then SQL Server has all the requested memory. If it is smaller, SQL Server can use more memory.

Switch - Average Wait Time: This counter shows the average time required to receive the key. This value should be as low as possible. If it is unusually high, you may need to look for a process that prevents other operations. You may also need to check the user's T-SQL statements and check for other I / O bottlenecks.

SQL Server Profiler

Microsoft recently announced that SQL Server Profiler for database engines will not be used in future releases. However, this tool is still useful. It comes with MS SQL Server and is very good at defining events that happen under the title, such as understanding how SQL statements are handled internally, which scripts are running to obtain T-SQL commands and other functions.

You can store the information collected by SQL Server Profiler in files or database tables, so you can export them later and use them in other applications for analysis. SQL Profiler works with traces. A number of events and information about the relevant SQL Monitor Tools activity data. You make a trail to watch the activity. They tend to store too much information, so you need to narrow them down by applying filters. 

Complaints about the large amount of information and additional costs provided by the track led to some controversy between developers and DBAs. Like other utilities, key details and correct configuration are key. You can learn more about the SQL Server Profiler in this MSDN article.

Monitoring SSMS Activity

The Activity Tracking Utility is a good tool that provides a brief overview of SQL Server system performance in SQL Server Management Studio. You can also view information about Processes Time, Standby Stats, DB I / O, Batch Requests, Standby Resources, I / O Data Files, and queries as well as Processes and Keys. In many ways, this tool offers functionality similar to Performance Monitor. This article describes the Activity SQL Monitor Tools in detail.

SQL Server Error Log

Some systems and user-defined events are logged in the SQL Server error log, such as the Windows Application Event Log. Information in this log helps you solve problems, and allows operations such as backup and recovery, batch commands, and other scripts to work as expected. Error logs can help identify potential problems, including automatic recovery messages (especially if the instance of SQL Server has stopped and has been restarted), core messages, or other server-level error messages.

The SQL Server error is logged in the form of a text file and can be viewed with any text editor. By default, these files are located in the ErrorLog and ErrorLog.n files in the Program Files \ Microsoft SQL Server \ MSSQL.n \ MSSQL \ LOG \. Each new instance of SQL Server comes with a new error log and SQL Server keeps backups for the last six days with SQL Monitor Tools.
