I would really like to see the following improvement in Munin:
- More verbosity upon detecting errors when parsing the munin.conf file. As of today, pinning down exactly what is wrong in the config file can be a tiresome exercise when dealing with aggregated graphs. Example: When grap_order lists a unknown field, the graph just don't generate. Some sort of verbosity level setting would be nice.
- Some way of telling when a host no long is responsive (no contact, host is down for say 15 minutes) on the front page. This can for example be denoted by a red star (*) after the hostname. I am aware that we usually have Nagios or other tools to detect more immediate alerts, but take for example: I just checked a host by random today, and munin had not getting any data for the last 5 days(!). The host was up and Nagios reported no problems. It turns out that the munin-node was not running on that particular hosts. This could easily been detected by some form of notice on the front-page.
