degussa_exporter
Prometheus Exporter for Degussa Goldhandel prices
Purpose
This exporter was specifically written to learn Prometheus' client_golang library, especially to serve as a testing ground for more advanced topics such as using GuageVecs and histograms.
Exported Metrics
Metrics are available on port 7979 (the atomic number of gold lol) under the standard URL /metrics.
The program exports all listed item prices on Degussa's price page. Prices are scraped at the same rate that Degussa publishes them, ca. 5 minutes.
Example
