Enterprise Monitor-ing the Raspberry Pi & MySQL Cluster
Employee +1 Vote Up -0Vote Down

So, now I’ve got my Raspberry Pi’s tested, and running MySQL Cluster we’ll need some form of checking it’s up and running, as with the rest of our MySQL servers.

Monitoring via a Remote Agent

First issue, of course, is that, with my existing MEM console, I have no need to re-install MEM, but rather want to deploy an agent so that I can monitor the MySQL Cluster.
This poses it’s first problem, as there isn’t an ARM-ready agent software available. Remember, it’s not a supported platform. So what can we do? Setup a remote Enterprise Monitor agent, so that, we can monitor the MySQL Cluster, albeit at …

Ok, so when we pull the plug on one of the pi’s, we have of each component falling down, but because one of them is the arbitrator (node-id=2) then cluster falls over.

Connected to Management Server at: localhost:1186

Look at this beauty (taken from the site of Calxeda, the manufacturer):
