How to monitor the load balanced workload in apache cluster + mysql cluster ???

Hi, I already configure the How to apache clustering and mysql clustering with load balancing. Here i got a small question ...

1) How do i know the workload balanced in mysql cluster or apache cluster to sql node ?? Any build-in command that we can monitor the workload between two sql node ?

Thanks for any reply !!!

 

You can run

Code:

top

on each node to see the load average, or you install something like munin on each node: http://www.howtoforge.com/server_monitoring_monit_munin

 

Can i install monit&munin on load balancer to monitor both sql node 1&2 workload at the once ????

 

I think this is possible, but I've never done it.
