Roman Borschel 807329ddb8 Add support for sourced metrics. (#6895 )

* Add support for sourced metrics.

A sourced metric is a metric that obtains its values
from an existing source, rather than the values being
independently recorded. It thus allows collecting
metrics from existing counters or gauges without
having to duplicate them in a dedicated prometheus
counter or gauge (and hence another atomic value).

The first use-case is to feed the bandwidth counters
from libp2p directly into prometheus.

* Tabs, not spaces.

* Tweak bandwidth counter registration.

* Add debug assertion for variable labels and values.

* Document monotonicity requirement for sourced counters.

* CI

* Update client/network/src/service.rs

Substrate Prometheus Exporter

Introduction

Prometheus is one of the most widely used monitoring tools for managing highly available services supported by Cloud Native Computing Foundation. By providing Prometheus metrics in Substrate, node operators can easily adopt widely used display/alert tools such as Grafana and Alertmanager. Easy access to such monitoring tools will benefit parachain developers/operators and validators to have much higher availability of their services.

Metrics will be served under /metrics on TCP port 9615 by default.

Quick Start

From the root of the repository start Substrate cargo run --release.
In another terminal run curl localhost:9615/metrics to retrieve the metrics.

To learn how to configure Prometheus see the Prometheus Getting Started guide.
