Handler read rnd next Documentation 22 G 21964273553 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.

Qcache lowmem prunes Documentation 0 0 The number of queries that have been removed from the cache to free up memory for caching new queries. This information can help you tune the query cache size. The query cache uses a least recently used (LRU) strategy to decide which queries to remove from the cache.
Qcache not cached Documentation 0 0 The number of non-cached queries (not cachable, or not cached due to the query_cache_type setting).
Qcache queries in cache Documentation 0 0 The number of queries registered in the cache.
Qcache total blocks Documentation 0 0 The total number of blocks in the query cache.

Select full join Documentation 2.2 M 2227519 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 428.2 k 428244 The number of joins that used a range search on a reference table.
Select range Documentation 21.9 M 21872909 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 8.3 k 8322 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.)

Threads cached Documentation 64 64 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 88 88 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.)
