[collectd] customizing metrics paths for various plugins

[Stuart Cracraft]

I need this also.

We use pingdom and have a large number of externally driven
metrics which we API out to and incoming from our network.

collectd is gathered and the charts are all flat and take up a lot
of space in graphite.

Anyone have any thoughts on InfluxDB and Grafana?
