| Threadpool threads | 0 | |
| Threads cached | 0 | 线程缓存中线程的数量。缓存命中率可以由 Threads_created/Connections 计算得出。如果该值是红色的，则应该增加 thread_cache_size 的值。 |
| Threads connected | 2 | 当前打开的连接数。 |
| Threads created | 29.9 k | 当前用于控制连接的线程数。如果 Threads_created 很大，您可能需要增加 thread_cache_size 的值。(如果线程状况良好，这么做通常并不会带来显著的性能提升。) |
| Threads running | 1 | 非睡眠状态的线程数量。 |
