Corentin Chary	7b6c3e556c	Use '.' instead of '=' to separate labels from their values in Graphite Using .label=value. was weird to use in Graphite and didn't bring much value.	10 years ago
Corentin Chary	a2e4439086	Add support for remote storage on Graphite Allows to use graphite over tcp or udp. Metrics labels and values are used to construct a valid Graphite path in a way that will allow us to eventually read them back and reconstruct the metrics. For example, this metric: model.Metric{ model.MetricNameLabel: "test:metric", "testlabel": "test:value", "testlabel2": "test:value", ) Will become: test:metric.testlabel=test:value.testlabel2=test:value escape.go takes care of escaping values to match Graphite character set, it basically uses percent-encoding as a fallback wich will work pretty will in the graphite/grafana world. The remote storage module also has an optional 'prefix' parameter to prefix all metrics with a path (for example, 'prometheus.'). Graphite URLs are simply in the form tcp://host:port or udp://host:port.	10 years ago
