MaxScale Nagios plugins, for Nagios 3.5.1
MaxScale must be configured with 'maxscaled' protocol for the administration interface
[AdminInterface]
type=service
router=cli
[AdminListener]
type=listener
service=AdminInterface
protocol=maxscaled
port=6603
1) copy check_maxscale_*.pl under /usr/lib64/nagios/plugins
2) copy maxscale_commands.cfg, server1.cfg to /etc/nagios/objects/
@ -11,10 +22,22 @@ cfg_file=/etc/nagios/objects/maxscale_commands.cfg
cfg_file=/etc/nagios/objects/server1.cfg
Please note:
- modify server IP address in server1.cfg
- modify server IP address in server1.cfg, pointing to MaxScale server
- maxadmin executable must be in the nagios server
- default AdminInterface port is 6603
- default maxadmin executable path is /usr/local/skysql/maxscale/bin/maxadmin
It can be changed by -m option
Example related to server1.cfg
# Check MaxScale sessions, on the remote machine.
define service{
use local-service ; Name of service template to use
host_name server1
service_description MaxScale_sessions
check_command check_maxscale_resource!6603!admin!skysql!sessions!/path_to/maxadmin
notifications_enabled 0
}
4) Restart Nagios
