A guide to building a robust logging system in Python, covering structured logging, log levels, handlers, formatters, filters, and integrating logging with modern observability practices.
This article provides an overview of OpenTelemetry, an open-source observability framework, and guides on integrating it with Go applications. It covers key concepts like logs, metrics, and traces, and demonstrates setting up a reusable telemetry package using OpenTelemetry in Go.
Cloudflare, an internet infrastructure and security company, has upgraded its logging pipeline by migrating from syslog-ng to OpenTelemetry Collector. This change affects one of Cloudflare's largest data pipelines, processing millions of log events per second.
**Key Points**
* **Motivations:** Language compatibility, easier integration, enhanced metrics, and unified telemetry infrastructure.
* **Custom Components:** Custom exporter, modified file exporter, processors, and rate-limiters.
* **Migration and Future Plans:** Careful rollout, monitoring, and plans for more sophisticated log sampling techniques and open-source contributions.
* **Other Adopters:** Google, Splunk, Shopify, and GitHub are also adopting OpenTelemetry for various use cases.
