Mysqlworkbench performance analysis tool -- Performance dashboard

MySQLworkbench You can display server performance statistics in a graphical dashboard . If you want to display the dashboard , Please open a database server , Then select Manage... From the left navigation （"management"） tab . Then click dashboard ("dashboard").

 

Dashboard location

The following figure shows the information layout in the instrument cluster

Be careful This feature requires MySQL server5.6 Or higher

 

Dashboard layout

Network state (Network Status)

It highlights Mysql Statistics of network traffic sent and received by the server through the client connection , Including incoming network traffic , Outgoing network traffic and number of client connections

 

Network state

From top to bottom is ：
Number of incoming Networks （Incoming Network Traffic） Unit byte / second
Number of outgoing Networks （Outgoing Network Traffic） Unit byte / second
Number of client connections （Client connections）

MySQL state （MySQL status）

It highlights MySQL Server main activity and performance statistics . Data includes open table cache hit efficiency （MySQL How to open the table ）, Executive sql sentence , as well as SELECT,INSERT,UPDATE,DELETE,CREATE,ALTER and DROP Count of statements （ Per second ）.

 

MySQL Status

From top to bottom is
Open table cache hit rate (Table Open Cache). Mouse over for more details
sql Statement execution (SQL Statements Executed)

InnoDB state (InnoDB Status)

Here is provided by InnoDb Store engine generated InnoDB Overview of buffer pool and disk activity . The data is divided into three groups

Be careful

Hover over the chart to view other information , For example, total count .

1. usage

• Read request （read reqs）：InnoDB The number of logical read requests executed on the buffer pool （ Per second ）
• Write requests （write reqs）：InnoDB The number of logical write requests to the buffer pool （ Per second ）
• Disk read （disk reads）：InnoDB The number of times logical reads cannot be made from the buffer pool . These must be read from disk
• InnoDB Buffer pool usage （InnoDB Buffer Pool）： In use InnoDB Percentage of buffer pool . Hover over to view additional information , Such as usage and idle pages （InnoDB Buffer pool ）

1. Write

• Written data （data written）： write in InnoDB Write times of redo log file
• write in （writes）： write in InnoDB The number of physical writes to redo log files
• InnoDB Disk write （InnoDB Disk Writes）： Hover the mouse to view the number of disk writes in a specific second . See the last 120s
• write in （writing）： from InnoDB The total amount of data written by the storage engine using file operations （ In bytes ）.

1. read

• Double write cache frequency (Doublewrite Buffer)： Number of double cache writes performed .
• InnoDB Disk read （InnoDB Disk Reads）： Hover the mouse to view the number of disk reads in a specific second . See the last 120s

• Read （reading）： from InnoDB The total amount of data read by the storage engine in file operations （ In bytes ）.
