mastodon_api_exporter

a prometheus exporter that gets some metrics from the mastodon api

while it's possible to get metrics into prometheus from mastodon using the statsd exporter, the set of metrics that are exposed does not include those that are exposed in the mastodon API.

this exporter gets some metrics from that API into prometheus.
