ordered by executions:The top SQL that is sorted by the number of executions of SQL is recorded. This sort shows the number of SQL executions that are within the scope of the monitoring.4.6 SQL ordered by Parse Calls:Top SQL that records the number of soft parse times for SQL. When it comes to soft-parsing (soft prase) and hard-parsing prase, it's impossible to say how Oracle handles SQL.4.7 SQL ordered by sharable Memory:The top SQL that SQL occupie

It is also necessary to perform basic monitoring on a single server or VPS. In the past, Zhao Rong did not monitor VPS, because when some servers were added, his performance became even more tense. There are also a lot of foreign server performance monitoring websites, but it is a little difficult for people like Zhao
System optimization is a complex, complex, and long-term task. monitoring, collection, testing, and evaluation are required before optimization. After optimization, testing, collection, evaluation, and monitoring are also required, it is also a long-term and continuous process. It is not to say that the optimization is now done, the test is done, and it can be done once and for all in the future. It is not
Brief introduction
Many Java applications today rely on a complex set of distributed dependencies and moving parts. Many external factors can have an impact on the performance and availability of your application. These effects are largely not completely eliminated or resolved, and are difficult to simulate accurately in a prebuilt environment. Stuff happens. However, you can create and maintain a comprehensive system to monitor the entire ecosystem

Reference Sun Java System application Server Enterprise Edition 8.2 Performance Tuning guide), this ratio is not suitable for all situations, especially when local variables in your application are far greater than the global variables, and a large number of local variables have a short life cycle. How to reasonably configure the proportio

Non-intrusive monitoring of PHP application performance monitoring analysis
The so-called non-intrusive monitoring of PHP application performance means to monitor the system without modifying the existing system code. Such a system can be easily applied to PHP applications.
Throughout the performance testing process, monitoring plays a vital role. After the performance test starts, you need to observe in real time whether all the indicators of the performance test are normal, including application servers, databases, and middleware. Once exceptions are detected, the system can be correcte
