mysql 主要性能指標
1.mysql connections->threads cached->threads cached
mysql connections->threads cached->threads connected(已用連接數,連接池)
mysql connections->threads cached->connections per second
2.表緩存，已經打開的表數
3.已經打開的文件數
4.QPS/TPS
show status like ‘queries‘
QPS：Query per second，每秒查詢量
show status like ‘com_commit‘
TPS：Transaction per second，每秒事物量
TPS = (Com_commit + Com_rollback) / Seconds
5.DML persecond圖標
對應mysql innodb rows
6.Transaction Persecond(mysql innodb transactions)
commit/rollback
7.innodb (mysql innodb buffer pool)
innodb buffer pool reads
innodb buffer pool pages flushed
8.key buffer
key buffer read rate
key buffer write rate
key blocks used rate
9.network
bytes_received,bytes_sent
10.aborted
aborted_clients,aborted_connects
11.MySQL InnoDB, MySQL InnoDB Buffer Pool
database pages InnoDB Buffer Pool Pages Data
free pages InnoDB Buffer Pool Pages Free
modified pages InnoDB Rows Modified per second
12.MySQL Performance
MySQLTransactions Handler
handler commit InnoDB Transaction Committing
handler rollback InnoDB Transaction Rolling Back
handler savepoint
handler savepoint rollback
InnoDB Last Checkpoint at per second (MySQL InnoDB, MySQL InnoDB Log File)
13.MySQLProcesslist
具體如下
show processlist;
show full processlist;
show open tables;
show status like ‘%lock%’
show engine innodb status\G;
show variables like ‘%timeout%’;
1.線程池
thread_cache_size = 32
thread_stack = 512K
#innodb_file_io_threads = 8
innodb_thread_concurrency = 16
#thread_stack = 192K
#thread_concurrency = 128
尤其註意以下監控項
