Work with Prometheus metric types

Counter

Use Flux to query and transform Prometheus counter metrics stored in InfluxDB. A counter is a cumulative metric that represents a single monotonically increasing counter whose value can only increase or be reset to zero on restart.

Gauge

Use Flux to query and transform Prometheus gauge metrics stored in InfluxDB. A gauge is a metric that represents a single numerical value that can arbitrarily go up and down.

Histogram

Use Flux to query and transform Prometheus histogram metrics stored in InfluxDB. A histogram samples observations (usually things like request durations or response sizes) and counts them in configurable buckets. It also provides a sum of all observed values.

Summary

Use Flux to query and transform Prometheus summary metrics stored in InfluxDB. A summary samples observations, e.g. request durations and response sizes. While it also provides a total count of observations and a sum of all observed values, it calculates configurable quantiles over a sliding time window.
