Metrics

Here is the full list of metrics exported as timeseries by ntopng.

There are two types of metrics exported by ntiong currently: counters and gauges.

  • counters are used for continuous incrementing metrics such as the total number of bytes.
  • gauges are used for metrics such as the number of active flows or active hosts at a certain point in time.

ntopng supports two backends for storing timeseries: RRD and InfluxDB. The supported resolution may change based on the backend and can be configured through the Runtime Preferences (this is the case of InfluxDB for some of the metrics as reported below).
