Deep technical references — heavy with multi-language code and diagrams. Start at the top; each one turns a system you can't see into one you can.
01
Implementing Audit Trails with OpenTelemetry
An audit trail is not a log. It's a tamper-evident, time-ordered record of who did what, when, and why. Most teams build this wrong. Here is how to do it correctly using OpenTelemetry and append-only storage.
02
Observability Under Compliance: GDPR, HIPAA, SOC 2, and PCI DSS
Regulated industries need observability too. A guide to building telemetry pipelines that satisfy GDPR, HIPAA, SOC 2, and PCI DSS requirements — covering data minimisation, retention mandates, audit trails, and what each framework actually requires.
03
Data Masking in Telemetry: The Art of Safe Transformation
Telemetry data is just as risky for PII as any database. Here's how to turn sensitive fields into safe, useful signals: hashing, tokenising, coarsening, and picking the right tool for the job.
04
High-Throughput Logging: Scaling Observability to Internet Scale
When your systems hit hundreds of thousands of requests per second, traditional logging collapses. Here is how to rethink collection, sampling, and export for extreme scale.
05
Your Traces Are Leaking User Data
Every OTel span that includes a customer email, shipping address, or payment token is a GDPR audit waiting to happen. The fix isn't application code; it's a Collector pipeline.
