General Concepts

Connectors

Connectors are yaml files which describe how to collect metrics about a specific resource (a host, an application, a service, etc.). There are two types of connectors:

• The Community Connectors which are open-source and bring basic monitoring coverage,
• The Enterprise Connectors which are a proprietary library of connectors developed by Sentry Software^[1] which offers extended hardware monitoring.

Anyone is encouraged to create their own connectors and share them with the community^[2].

Metrics

Telemetry data collected by MetricsHub which provide valuable information about the monitored resource.

Monitors

Custom connector, set in metricshub.yaml, which defines how to collect metrics about a specific resource. A monitor defines a job which executes sources, computes, and collects metrics.

OTLP

OTLP is the OpenTelemetry protocol used to exchange data between MetricsHub and an observability back-end.

OTLP Receiver

An OTLP receiver acts as an entry point for metrics into an observability back-end or OpenTelemetry Collector.

Resource Group

Resource group helps organize and manage the monitored resources in a structured manner.

Resource

Generic term to cover anything monitored by MetricsHub. A resource can be a host, a service, an application, etc.
