MySQL Monitor is used to help us analyze the running status of MySQL and give certain reasonable suggestions through status analysis. The key MySQL status is organized and summarized, which is helpful to grasp the operating status of MySQL. In addition, you can also try to write your own MySQLMonitor extension. Several MySQL servers can be monitored. By switching the monitoring information, you can find out which settings of these MySQL servers are unreasonable or inconsistent. The company I work for has a fair number of MySQL servers, and before using this software it was difficult to find out if there were any settings in one set of servers that were different from others.
