myStatusgo

myStatusgo is a realtime monitoring tool for MySQL with status information,performance schema(MySQL5.6+) and etc..(terminal base) This tool can monitor multiple MySQL instances.

myStatusgo collects metric and display them.

1. Normal.. Display QPS info from Com_xx of SHOW GLOBAL STATUS
2. OS Metric.. Display QPS info and OS metric. OS metric collect from node_expoter when the MySQL server installed node_expoter
3. Threads.. Display Running Threads from performance_schema.threads table. (MySQL5.6+)
4. P_S Info.. Display digest_text from performance_schema.statement_digest table (MySQL5.6+)
5. SlaveStatus.. Display Slave Info from SHOW SLAVE STATUS
6. Handler/InnoDB_Rows.. Display innodb_row_xx and Handler_xx from SHOW GLOBAL STATUS
7. InnoDB Lock Info.. Display InnoDB Row Lock Info from information_schema.innodb_trx and innodb_locks and innodb_lock_waits (MySQL5.6+)
8. InnoDB Buffer Info.. Display InnoDB Buffer Pool Info from information_schema.INNODB_METRICS (MySQL5.6+)
9. Table IO Statistic.. Display information of I/O request of each table and information on the number of SELECT/DML for each table from performance_schema.file_summary_by_instance and performance_schema.table_io_waits_summary_by_table (MySQL5.6+)

Grants

myStatusgo needs following permissions user

GRANT SELECT on performance_schema.* to 'user'@'host';
GRANT PROCESS,REPLICATION CLIENT on *.* to 'user'@'host';

Install

go get -u github.com/kenken0807/myStatusgo

The binary will be builted and installed into $GOPATH/bin/.

Quick Start

$ myStatusgo -hc Hostname:Port[:alias],Hostname:Port[:alias] -u User -p Password

Example $ myStatusgo -hc 192.168.0.1:3306:Master,192.168.0.2:3306:Slave1 -u user1 -p userpass

How to specify Hostname

There are three ways to specify hosts.

• -h option JSON format

$ myStatusgo -h '{"ServiceList":[{"serviceName":"Sample","host":["192.168.0.1:3306","192.168.0.2:3306"]}]}'

• -hc option Comma separated

$ myStatusgo -hc 192.168.0.1:3306,192.168.0.2:3306

• Specify a file as an argument

$ vim hostlist
# Sample
192.168.0.1:3306
192.168.0.2:3306

$ myStatusgo hostlist
