Innodb buffer pool wait free Documentation 0 0 Normally, writes to the InnoDB buffer pool happen in the background. However, if it's necessary to read or create a page and no clean pages are available, it's necessary to wait for pages to be flushed first. This counter counts instances of these waits. 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 581.2 k 581206 The number of joins that do not use indexes. If this value is not 0, you should carefully check the indexes of your tables.
