It's fairly easy to throw in new graphs, and I like that.  One of the
drawbacks is that it spends a lot of CPU building the graphs etc - if I
continue adding graphs in my current speed, and we set up even more
servers, soon it will take us more than five minutes generating the

Also, local configuration can be tricky.  Locally I fix this by loading
a config file with a hard-coded path.  Luckily, as long as the postgres
munin plugins are run at localhost as the postgres user, most of them
don't need any configuration.  Still, it can be useful to tune the alarm

What layers of security do you need?  We're using https, basic auth and
ssh-tunnels.  We've considered the munin data to be regarded as
confidential, at the other hand it's nothing ultra-secret there; i.e.
securing the backups of the production database probably deserves more
