Does exactly what it claims to do
by crtelinde, March 31, 2016
This is a solid plugin that does what it sets out to do.

There is a little extra work in implementing the plugin. You are best off executing the plugin remotely, since it depends on ndb_mgm. I did this by using the 'check_by_ssh' plugin in conjunction with this plugin. This can also be done with NRPE.

The only issue I notice is that the memory percentages are not being displayed on on Nagios web interface like they do when running the command via the terminal.

The ndb_mgm binary location needed to be updated in the script to look at /usr/bin/mgm, as someone else pointed out.

Cool plugin

Very simple to use.
I'm using MySQL 5.6 and needed to change the ndb_mgmd path and name to
/usr/bin/ndb_mgm

Other than that- all worked well.
Thanks!
