How to deploy multiple charms onto a set of VMs

[Haitao Jiang]

Hi,

I have a question: we wrote a set of charms to deploy services, which
juju deployed them into different VMs. For each of these VMs, we would
like to deploy a common monitoring service like Nagios, how to do
that?

Do we have to combine Nagios charm with each of our other service
charms? What is the best practice in this situation?

Thanks a lot
