2. PMM-CLIENT1. Install pmm-clientyum install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm # configure percona source yum install pmm-client # install pmm-client2 on the machine you need to monitor. Configure pmm-server addr

-- server is followed by the address and port of pmm-server

-c is followed by a configuration file, and the default configuration file is / usr/local/percona/pmm-client/pmm.yml

Pmm-admin config-- server xx.xx.xx.xx:8888-c / usr/local/percona/pmm-client/pmm.yml

Create a monitoring user in the MySQL instance:

GRANT SELECT, PROCESS, SUPER, REPLICATION CLIENT, RELOAD ON *. * TO 'pmm'@'127.0.0.1' IDENTIFIED BY' pmm' WITH MAX_USER_CONNECTIONS 10 politics Grant SELECT, UPDATE, DELETE, DROP ON performance_schema.* TO 'pmm'@'127.0.0.1'

Add MySQL Monitoring

Pmm-admin add mysql-- host 127.0.0.1-- user pmm--password pmm--port 3306 instance3306 # # this command monitors the status of MySQL instances and slow query analysis. If you do not want to monitor slow logs, you can use mysql:metrics. 3. Problems encountered 1. Purge error

When a machine goes offline, you need to clean up the data about this machine in pmm-server, and report an error after executing the purge command.
