Handler read retry Documentation 0 0
Handler read rnd Documentation 1.2 G 1182921452 The number of requests to read a row based on a fixed position. This is high if you are doing a lot of queries that require sorting of the result.

Handler read rnd next Documentation 10 G 10049505765 The number of requests to read the next row in the data file. This is high if you are doing a lot of table scans.

Select full join Documentation 14.7 M 14748037 The number of joins that do not use indexes. If this value is not 0, you should carefully check the indexes of your tables.
Select full range join Documentation 1.6 M 1568082 The number of joins that used a range search on a reference table.
Select range Documentation 33.3 M 33273646 The number of joins that used ranges on the first table. (It's normally not critical even if this is big.)
Select range check Documentation 0 0 The number of joins without keys that check for key usage after each row. (If this is not 0, you should carefully check the indexes of your tables.)
Select scan Documentation 20.3 M 20341455 The number of joins that did a full scan of the first table.

Slow queries Documentation 40 40 The number of queries that have taken more than long_query_time seconds. Documentation
Sort merge passes Documentation 194 194 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.

Table locks immediate Documentation 157.4 k 157363 The number of times that a table lock was acquired immediately.
Table locks waited Documentation 0 0 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 11 11 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 10 10 The number of currently open connections.
Threads created Documentation 21 21 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 6 6 The number of threads that are not sleeping.
