sql performance counters

SQL Server database mirroring key Performance countersThere are 5 basic methods of monitoring database mirroring:1. Configure the database Mirroring Monitor, set the alarm threshold value.2. Configure WMI EVENT ALERT to configure the action or alarm after the mirror state is modified.3. Use System Monitor to view key performance

Server CountersThe Access Methods object in SQL Server provides a counter that monitors access to logical data in the database, and the Buffer Manager counter monitors physical access to the database on disk. Access Methods access Mode Access methods monitors the methods used to access data stored in the database to help determine whether you can improve query performance by adding or modifying indexes, ad

performance counters to solve a database storage problem. During this process, I noticed some very strange phenomena: even though no operations are performed in the database, there are still write activities in the database files. This situation exists in both data and log files. This situation continues even when I make sure that I am not connected to SQL Serve

MySql counters, such as the number of clicks on a website, how to implement high-performance and high-concurrency counters MySql counters, such as the number of clicks on a website, and how to implement high-performance and high-concurrency

Implement High-performance and high-concurrency counters in MySQL (such as the number of clicks in articles) and mysql counters There are a lot of projects that implement counters at will. For example, when we implement the number of clicks on a website article, we design data tables like: "article_id, article_name, ar

From: http://bbs.51testing.com/thread-2196-1-1.html Hello everyone. In the future, we will discuss the design and design of LR monitoring performance counters and LR scenarios. Today, I will first paste out some counters and their threshold requirements. These counters are aimed at My

: the average time required to write data to this disk in seconds. Network Interface: Bytes total/sec: the speed at which bytes are sent and received, including frame characters. Determine whether the network connection speed is a bottleneck. You can use the counter value to compare with the current network bandwidth. Sqlserver performance counters: Access methods (access method) is used to monitor the meth

ASP.net supports two sets of performance counters: systems and applications. The former is exposed in PerfMon in the asp.net performance counter object, which is exposed in the asp.net applications performance object. The state server Sessions counter in the asp.net performance
