Code:

[root@localhost glusterfs]# gluster volume info

Volume Name: mysql-db
Type: Replicate
Volume ID: 7fd3178c-30d5-496e-8653-91be074d80da
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: node1:/data/gluster/brick
Brick2: node2:/data/gluster/brick
Options Reconfigured:
performance.readdir-ahead: on
[root@localhost glusterfs]#
[root@localhost glusterfs]# mount -t glusterfs node1:/mysql-db /opt/mysql
[root@localhost glusterfs]# df -h
Filesystem                  Size  Used Avail Use% Mounted on

/dev/sda1                   497M   98M  400M  20% /boot
/dev/mapper/vol_san1-mysql  500G   33M  500G   1% /data/gluster
node1:/mysql-db           50G  3.2G   47G   7% /opt/mysql
[root@localhost glusterfs]#

pmdamysql

PMDAMYSQL(1)						       Performance Co-Pilot						      PMDAMYSQL(1)

NAME

       pmdamysql - MySQL database PMDA

DESCRIPTION

       pmdamysql is a Performance Co-Pilot PMDA which extracts live performance data from a running MySQL database.

INSTALLATION

       pmdamysql uses a configuration file from (in this order):

       o   /etc/pcpdbi.conf

       o   $PCP_PMDAS_DIR/mysql/mysql.conf

       This file can contain overridden values (Perl code) for the settings listed at the start of pmdamysql.pl, namely:

       o   database name (see DBI(3) for details)

       o   database user name

       o   database pass word

       Once this is setup, you can access the names and values for the mysql performance metrics by doing the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Remove

       pmdamysql is launched by pmcd(1) and should never be executed directly.	The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.

Binary Status values in text
       Some of the status values are in the form of YES/NO or ON/OFF.

       Since these cannot be intepreted by tools like PMIE, they have been duplicated with a _num extension and the values of 1 (YES/ON) or 0
       (NO/OFF).

   Eg:
       o   mysql.slave_status.slave_io_running

       o   mysql.slave_status.slave_io_running_num
