This looks very interesting. From http://prometheus.io/docs/introduction/getting_started/ > Prometheus collects metrics from monitored targets by scraping metrics HTTP endpoints on these targets. I wonder if we'll see some plugins that allow data collection via snmp or nagios monitoring scripts or so. That would make it much easier to switch large existing monitoring systems over to prometheus.
(One of the authors here) Just last night I wrote the https://github.com/prometheus/collectd_exporter , which you could do SNMP with. I do plan on writing a purpose-designed SNMP exporter in the next a few months to monitor my home network, if someone else doesn't get there first.
Awesome. I wondered if I should mention collectd as a possible source of data, and now you've already made it available.
