Logs
Use Logs for timestamp-ordered operational events with service, trace, version, and deployment context.
Overview
Use Logs to reconstruct what the application said over time. Logs are best for event sequence, warnings, deployment context, service context, and trace correlation during an investigation.
Use this page after you know the approximate symptom and need to decide which evidence should come next. Keep the service, environment, and time range consistent as you move from summary pages to request-level detail.
How to read this page
Start with time range, service, environment, severity, and text filters. Keep logs in timestamp order when reconstructing an incident. Use trace and service links to move from event text to request or service evidence.
- Time order
- Read logs in timestamp order when reconstructing an incident or release window.
- Correlation
- Trace, span, service, version, and deployment fields turn event text into navigable evidence.
- Severity and message
- Severity narrows urgency. Message and event names explain what the application reported.
Investigation workflow
Use this sequence when you need to move from a broad symptom to evidence you can share with another teammate.
- 1
Open Logs from a trace or service so the filters already match the evidence.
- 2
Remove the text filter first if the expected event is missing.
- 3
Open the related trace when a log line marks a failed operation or slow branch.
Interpretation note
Do not start with text search before setting service and time range. Do not treat logs without trace links as useless. They can still explain service-wide context. Do not compare log counts without checking severity and sampling of application events.
