Munin to InfluxDB+Grafana gateway

Tool to migrate smoothly from Munin (RRD) to InfluxDB and Grafana dashboards.

Contains (err, will contain) two parts:

• import
  • Import existing Munin data to InfluxDB (groups fields in the same series by default). Status: done
  • Generate a Grafana dashboard based on the existing Munin configuration. Status: done
• fetch
  • Update InfluxDB with fresh data from a still running Munin service: Status: done
  • Run Munin's plugins but export to InfluxDB instead. Status: not started

Data from Munin RRD databases are combined and imported into an InfluxDB cluster.

Munin fields from a same plugin are grouped as columns of the same InfluxDB time series.

Grafana layout settings are imported from Munin plugin's configuration. Supported elements:

• Min, max, average and current values in legend table
• Line, area, stacked metrics
• Warning, critical thresholds
• Graph orders
• Aliases
• Tooltip overlays
• Metrics colors
• Multigraphs (partial support)
