  • What is synthetic monitoring?

    Synthetic monitoring runs scripted probes (HTTP checks, API transactions, browser journeys) on a schedule from controlled locations to catch outages before users do.

  • What is SRE? Site reliability engineering explained

    Site reliability engineering (SRE) applies software engineering to operations problems, using SLOs, error budgets, a 50% toil cap, and blameless postmortems to keep systems reliable.

  • What is shadow AI? The governance gap in AI adoption

    Shadow AI is the use of AI tools and models inside an organization without IT or governance approval. It drives data leakage, unbudgeted spend, and compliance exposure, and detecting it is an observability problem.

  • What is real user monitoring (RUM)?

    Real user monitoring (RUM) passively collects performance and experience telemetry from real user sessions. How it works, what it captures, and how to store it at scale.

  • What is platform engineering?

    Platform engineering is the discipline of building internal developer platforms (IDPs) that give product teams self-service infrastructure through golden paths, reducing cognitive load.

  • What is MELT? Metrics, events, logs, and traces explained

    MELT groups telemetry into metrics, events, logs, and traces. What each type captures, how events differ from logs, and how MELT relates to the three pillars of observability.

  • What is log management? Lifecycle, retention, and tooling

    Log management is the discipline of handling logs across their full lifecycle: generation, collection, parsing, storage, retention, query, and deletion.

  • What is log analytics? Querying logs at scale

    Log analytics runs aggregations, time series, and pattern detection over centralized logs, turning billions of log lines into answers about system behavior.

  • What is log aggregation? Centralizing logs from every service

    Log aggregation collects log data from every service, host, and container into one queryable store, so engineers can search and correlate events across a whole system.

  • What is eBPF? Kernel-level observability without code changes

    eBPF runs sandboxed programs inside the Linux kernel to capture traces, network flows, and profiles without changing application code. How it works, where it falls short, and how to query its output at scale.

  • What is distributed tracing? Traces, spans, and context propagation

    Distributed tracing follows one request across every service it touches, recording each step as a span under a shared trace ID so you can see where the time went.

  • What is AIOps, and what does it actually deliver?

    AIOps applies machine learning to IT operations data to detect anomalies, correlate events, and cut alert noise. What it does well, where it stops, and what it needs underneath.

  • What is AI agent observability?

    AI agent observability traces multi-step, non-deterministic agent workflows (LLM calls, tool calls, retrievals, sub-agent spawns) as spans in one trace, so teams can debug agent behavior.

  • The three pillars of observability - and where the model breaks

    Logs, metrics, and traces defined honestly: what each pillar captures, when to use which, how they correlate, and why siloed pillars break down at scale.

  • What is tail latency? Why p99 spikes when averages look fine

    Tail latency is the slow end of the response-time distribution (p95 and beyond). Why fan-out makes rare slowness common, what causes it, and how hedged requests, timeouts, and load shedding reduce it.
