Awesome OpenTelemetry 
A curated list of OpenTelemetry resources.
What is OpenTelemetry?
OpenTelemetry is a collection of tools, APIs, and SDKs. Use it to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) to help you analyze your software’s performance and behavior

OpenTelemetry Registry
The OpenTelemetry Registry allows you to search for instrumentation libraries, tracer implementations, utilities, and other useful projects in the OpenTelemetry ecosystem.
Components
Reference Architecture
Client
Client libraries used to instrument applications for distributed tracing.
Other Libraries
Refer from OpenTelemetry Official Document
Agent
An agent listens for spans, which it batches and sends to the Collector. The agent is meant to be placed on the same host as the instrumented application. This is typically accomplished by having a sidecar in container environments such as Kubernetes or running it as a DaemonSet (on each node).
OTLP
OTLP is the default OpenTelemetry protocol for transmitting telemetry data. Other formats can be Zipkin or Jaeger.
Collector
Similar to the Agent, the Collector is able to receive spans and place them in an internal queue for processing.
The OpenTelemetry collector is a vendor-agnostic way to receive, process and export telemetry data.
The Collector consists of three components that access telemetry data:
- Receivers - How data gets into the Collector
- Processors - Processors are run on data between being received and being exported.
- Exporters - How you send data to one or more backends/destinations
For vendor specific receivers/exporters, see OpenTelemetry Collector Contrib
Receivers
A receiver is how data gets into the OpenTelemetry Collector. Generally, a receiver accepts data in a specified format, translates it into the internal format and passes it to processors and exporters defined in the applicable pipelines. source
Processors
Processors are run on data between being received and being exported. Processors are optional though some are recommended. source
Exporters
An exporter is how you send data to one or more backends/destinations. Exporters may support one or more data sources.
Storage
The OpenTelemetry collectors require a persistent storage backend.
- Cassandra - open source NoSQL distributed database
- Elasticsearch - open search and analytics solution
- Jaeger - distributed tracing platform created by Uber Technologies
- SkyWalking - open source APM system
- Tempo - Grafana Tempo is an open source, easy-to-use, and high-scale distributed tracing backend.
Ingester
You can optional use an Ingester, which is a service that reads data from Kafka and writes to the storage backend.
- Kafka - open-source distributed event streaming platform
UI
Visualizing the distributed tracing data.
