Sort merge passes Documentation 65 65 The number of merge passes the sort algorithm has had to do. If this value is large, you should consider increasing the value of the sort_buffer_size system variable.
Sort priority queue sorts Documentation 8.3 k 8343
Sort range Documentation 71.1 k 71138 The number of sorts that were done with ranges.
Sort rows Documentation 145.3 M 145348472 The number of sorted rows.
Sort scan Documentation 6.8 M 6836301 The number of sorts that were done by scanning the table.

Table locks immediate Documentation 4 M 3981090 The number of times that a table lock was acquired immediately.
Table locks waited Documentation 152 152 The number of times that a table lock could not be acquired immediately and a wait was needed. If this is high, and you have performance problems, you should first optimize your queries, and then either split your table or tables or use replication.

Threads cached Documentation 0 0 The number of threads in the thread cache. The cache hit rate can be calculated as Threads_created/Connections. If this value is red you should raise your thread_cache_size.
Threads connected Documentation 24 24 The number of currently open connections.
Threads created Documentation 659 659 The number of threads created to handle connections. If Threads_created is big, you may want to increase the thread_cache_size value. (Normally this doesn't give a notable performance improvement if you have a good thread implementation.)
Threads running Documentation 7 7 The number of threads that are not sleeping.
