SRE
Apply KISS to the configurations your responders must understand
Use operational state, visible defaults, and reversible transitions to evaluate complexity without discarding necessary capabilities.

How-To
Metrics for observability: choose the question before the chart
Counters, gauges, and distributions answer different questions. Build metrics that preserve scope, denominators, and the evidence behind an incident.
How-To
Observability logs: preserve the events an investigation needs
Design logs around useful events, searchable context, and a collection path whose failures are visible.
How-To
Design an on-call rotation people can actually support
Define coverage, escalation, training, and recovery time before assigning the calendar. Review workload as well as shift counts.
SRE
SRE runbook template: diagnosis, bounded action, and recovery
Download a Markdown runbook template and follow a database connection example that separates symptoms, mitigation decisions, and verified recovery.
How-To
Containers and orchestration: understand what the platform guarantees
Containers package processes; orchestration reconciles desired state. Reliability still depends on probes, capacity, dependencies, and application behavior.
SRE
Turn postmortem lessons into changes you can verify
Translate incident findings into funded changes with an owner, a test, and evidence that the relevant failure mode became less likely or less costly.
Leadership & Culture
On-call overload: respond to the workload before it becomes normal
Use interruption patterns and responder feedback to change paging, coverage, and recovery expectations when on-call work becomes unsustainable.
Leadership & Culture
The reliability decisions an SRE leader must make
Give teams clear service ownership, decision authority, and capacity to act on reliability evidence before the next incident.
SRE
Service level objectives: define the experience you intend to protect
Choose an SLI, target, and evaluation window that reflect user experience, then agree on the decisions an SLO result will change.
How-To
Read a distributed trace without mistaking it for the whole system
Understand spans, parent-child relationships, retries, and missing evidence so traces support a careful diagnosis.
SRE
SRE feedback loops: check whether the signal still means the same thing
Connect telemetry, customer reports, decisions, and verification so improvements in a dashboard reflect improvements in the service.
