Technical
Technical dimension
The technical dimension is about getting the signal you need to troubleshoot, at the right cost. Every chapter starts from a concrete operations problem and gives the full configuration. The goal is to make it reproducible in a lab; the Labs page says which ones are published, and a chapter without a lab or with a configuration not yet run end to end says so.
If you are new to the topic, start with the first three chapters of the table, in order: they set out the vocabulary used everywhere else.
Published and upcoming chapters
Section titled “Published and upcoming chapters”| Chapter | What you learn to do | Status |
|---|---|---|
| Observability in 10 minutes | tell monitoring from observability, metrics, logs, traces, profiles and events apart, link them, reason about cardinality | published, for beginners; cardinality simulator |
| OpenTelemetry end to end | follow a span from the application to storage, instrument, configure a minimal Collector, apply semantic conventions | published, for beginners |
| SLOs and alerting | define SLIs and SLOs, compute an error budget, alert on burn rate instead of thresholds | published, for beginners; error budget simulator |
| Telemetry pipelines | design a Collector: filtering, transformation, sampling, routing | planned |
| Backends and storage | choose between Prometheus, VictoriaMetrics, Elastic, Loki, Tempo, ClickHouse | planned |
| AI observability | observe inference, RAG and MCP tools with an open source stack | published, with a full course |
| Log integrity | build an audit log a third party can verify | published |
| HPC and GPU infrastructure | tie every GPU metric to a job and an account, catch silent degradation | reference architecture, course in preparation |
| Agents, RAG and MCP | per-component measurement grids, probabilistic quality SLOs | GenAI method |
| VictoriaMetrics | a metrics backend for high-cardinality workloads | course |
| Edge and IoT | observe constrained, intermittent and heterogeneous fleets | planned |
Hands-on
Section titled “Hands-on”Trace explorer, clickable architecture, animated Collector pipeline, tail sampling, quality SLO. The rest are gathered on the tools and diagrams pages.
