Handler read rnd next Documentation 29.3 G 29316416301 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.

If the buffer pool size was set properly, this value should be small.

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 9.6 M 9636218 The number of joins that do not use indexes. If this value is not 0, you should carefully check the indexes of your tables.

Threads cached Documentation 169 169 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 34 34 The number of currently open connections.
Threads created Documentation 203 203 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.)
