Handler read key	802 802	The number of requests to read a row based on a key. If this is high, it is a good indication that your queries and tables are properly indexed.

Handler read retry	00
Handler read rnd	2.4 k2357	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. You probably have a lot of queries that require MySQL to scan whole tables or you have joins that don't use keys properly.
Handler read rnd deleted	86 86
Handler read rnd next	33.6 k33584	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. Generally this suggests that your tables are not properly indexed or that your queries are not written to take advantage of the indexes you have.

Cpu time

Created tmp disk tables

1.7 k

The number of in-memory temporary tables created automatically by the server while executing statements.

Delayed errors

Handler external lock

Handler icp attempts

Handler icp match

Handler mrr init

Handler mrr key refills

Handler mrr rowid refills

Handler read first

The number of times the first entry was read from an index. If this is high, it suggests that the server is doing a lot of full index scans; for example, SELECT col1 FROM foo, assuming that col1 is indexed.

Handler read key

802

The number of requests to read a row based on a key. If this is high, it is a good indication that your queries and tables are properly indexed.

Handler read last

Handler read next

The number of requests to read the next row in key order. This is incremented if you are querying an index column with a range constraint or if you are doing an index scan.

Handler read prev

The number of requests to read the previous row in key order. This read method is mainly used to optimize ORDER BY … DESC.

Handler read retry

Handler read rnd

2.4 k

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. You probably have a lot of queries that require MySQL to scan whole tables or you have joins that don't use keys properly.

Handler read rnd deleted

Handler read rnd next

33.6 k

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. Generally this suggests that your tables are not properly indexed or that your queries are not written to take advantage of the indexes you have.

Handler rollback

The number of internal ROLLBACK statements.

Handler savepoint

Handler savepoint rollback

Handler tmp update

Handler tmp write

37.6 k

Handler update

The number of requests to update a row in a table.

Tc log page size

4.1 k

Tc log page waits

Threadpool idle threads

Threadpool threads

Threads cached

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.
