OpenTelemetry  is a collection of APIs, SDKs, and tools. Use it to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) to help you analyze your software’s performance and behavior. It is a project by CNCF.

Collectors

• Buz serverless, auto-scaling collector that you can deploy and run yourself. Buz collects, validates, and delivers schematized data to where it needs to bee.

Sources:

• Event-tracking SDK's like Snowplow Analytics (Segment and others in development)
• Self-describing payloads
• Webhooks
• Pixels
• Cloudevents

Destinations:

• Databases like Postgres, Mysql, or Clickhouse
• Streaming tech like Pub/Sub, Kinesis, or Redpanda
• Hybrids like Kinesis Firehose
• Message brokers like NATS or RabbitMQ
• Indexes like Elasticsearch or Splunk

Quickstart talks about using redpanda with Buz.

1. who uses it, and how?
2. how do you interact with production?
3. how do you debug?
4. the cost model

The o11y 2.0 article mentions - Debunking the 'Three Pillars of Observability' Myth - Software Engineering Daily

Another issue with “The Three Pillars” is the very notion that we should always aspire to build software that’s appropriate for the “planet-scale” infrastructure at Google (or Facebook, or Twitter, and so on). Long story short: don’t emulate Google.
