### Please note:
- 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 MaxScale AdminInterface port is 6603
- default maxadmin executable path is /usr/local/skysql/maxscale/bin/maxadmin
It can be changed by -m option
- maxadmin executable could be copied from an existing maxscale setup (default location is /usr/local/skysql/maxscale/bin/maxadmin)
