GuideAI in production
Prompting an assistant to investigate an incident
A reusable prompt connects observations, competing explanations and the next read-only check, so an incomplete record can still support useful investigation.
How-To
Practical methods you can take back to your team.
GuidePlatform engineering
Finding a Linux write failure through paths and mounts
Directory conventions orient the investigation. Mounts, namespaces, inodes and service permissions explain which storage the failing process actually encounters.

Linux performance tuning starts with a bottleneck
A concurrency change can improve throughput and worsen tail latency. Comparable workloads and process-level limits help explain whether the change is worth keeping.
GuideIncident response
Customer reports reveal failures a fleet average can miss
An upload report becomes investigable through its operation, region and time window. That same detail connects the engineering result back to the customer.
GuideObservability
What makes an alert worth paging for
A capacity warning needs enough lead time and a reachable responder who can act. The alert review separates useful urgency from a missing response arrangement.
Where to start with Google’s free SRE books
A chapter-level starting point for alerting, on-call coverage and postmortems, with examples of adapting the practices to local staffing and authority.

What a canary deployment actually tests
Traffic assignment determines which behavior reaches a canary. Promotion also depends on the baseline, service objectives and state left behind by rollback.

Calculating mean time to detect from incident records
Worked incident records explain the MTTD formula, uncertain onset times and the effect of including failures first reported by customers.
ExplainerObservability
What observability metrics keep and leave out
Counters, gauges and distributions preserve different information. A misleading latency trend shows why the counted requests matter as much as the chart.

The path from a log event to an investigation
An unfinished worker operation connects event fields, collection loss and search permissions to the responder’s next retry decision.
Staffing an on-call rotation beyond the primary shift
Primary shifts, specialist help, absence coverage and recovery time all contribute to the service an on-call calendar promises.

How containers and Kubernetes turn an image into a service
Images package processes and Kubernetes reconciles their deployment. Probes, resource settings and completed jobs reveal different stages of the service.
