I am feeding nmon data from multiple servers into an InfluxDB and use Grafana for basic analytics/monitoring. The series feed into InfluxDB are named in simple patterns where elements are separated by a dot, for example:

[prefix].[servername].[nmon-section].[metric]

For example raw.raspi.CPU_ALL.SysPercent contains system cpu usage over all CPU's on the node raspi.

Now, for example, I would like to have a filter at the place of the [servername]. The query would look somehow like that:

from /raw.*'[[servername]]'*.CPU_ALL.*/ where  time > 1406045460s and time < 1406047512s group by time(1s)  order asc

A input box (in this case better than a dropdown) would allow me to filter.

Currently I do this via scripted dashboards which works fine, but thats somehow lacking of flexibility...
