IntroductionThis article is the second article in the Java Performance Analysis tool series, the first article: Operating system Tools. In this article, you will learn more about Java applications and the JVM itself using built-in Java monitoring tools. There are many built-in tools in the JDK, including: Jcmd

Performance bottlenecks:Slow, write faster than read The main performance indicators:Frequency of visits,The number of concurrent connections,Cache Hit Ratio,Index use,Slow log opening and analysis,Query log, querying logThreads_cached: Whether the connection thread cache is turned onThread_cache_size: The size of the number of thread cachesQuery_cache_size: Query Cache SizeJoin_buffer_size:join Buffer SizeSize of tmp_table_size:tmp table (> 16M)Max_h

performance testing, we need to use the tools provided by the operating system to collect various types of resource monitoring data in the operating system, including CPU, memory, and hard disk usage data. If the tested program uses the network, you also need to collect network usage data. Only when the collected
