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

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 SQL Server database and web platfo

Whether the bottleneck exists due to the lack of available physical memory to store frequently accessed data in the cache. If so, SQL Server must retrieve data from the disk.
Whether more memory can be added or used for data cache or SQL Server internal structure to improve query performance.
Lock blocks: Number of locked blocks on the server. The locks are on resources such as pages, rows, and tables. You do not want to see a growth

If there is not enough memory in the system to meet the requirements of all active programs, memory paging will occur and program performance will be affected. 8. If a memory leak occurs, the value of the Process/private bytes counter and the Process/working set counter is often elevated, while the available bytes is lowered. 9. If the process is miss
