Percona-Tookit工具包之pt-mysql-summary
Preface
Sometimes we need to collect information of MySQL server as a report when we first time take over the system by someone else.Espcially there're lots of servers for you to check them one by one with manual command.We need a simple tool to increase the efficiency when doing so.
Introduce
pt-mysql-summary can help us to print information of our MySQL servers nicely.It's not a tuning or diagnostic tool but a tool just provides us a report with neat format.
Procedure
Usage
1 pt-mysql-summary [OPTIONS]
Common Parameters
1 --all-databases //Specify the scope is all databases for summarizing. 2 --databases //Specify the only database for summarizing. 3 --default-files //Specify the configuration file to use. 4 --list-encrypted-tables //Specify to contain encrypted tables in all databases. 5 --read-samples //Create a report from this file you sepcified. 6 --save-samples //Save to the direcotry you want to store the summary. 7 --sleep //Seconds to sleep for counter.
Example
Execute pt-mysql-summary with just connect options(single master).
