visage-api - Reference documentation for the Visage JSON API
Visage is a web interface for viewing collectd statistics.
It also provides a JSON interface onto collectd's RRD data, giving you an easy way to mash up the data.
This man page documents the different ways you can call the API.
Calls to the API follow the /data/<hostnames>/<plugins>/<instances> pattern.
