Firewall log analysis: from rule match to investigation
Preserve rule decisions, review false positives, and connect edge events to application evidence.
LOGAPI FIELD NOTES
Less noise. More understanding.
Ten in-depth guides to the decisions behind better logging—from your first JSON event to a connected security investigation.
AI logging in production: context without oversharing
Instrument AI workflows with useful metadata, configuration versions, and clear outcomes—not entire conversations.
LLM observability: connect logs, traces, and outcomes
Trace retrieval, generation, validation, and retries without confusing model completion with application success.
Reliable log ingestion: queues, retries, and duplicates
Define delivery guarantees, bound your buffers, and make duplicate records and pipeline failures visible.
Token usage logging: measurements, estimates, and cost
Keep reported usage separate from estimates, handle retries, and make cost calculations explainable.
Log redaction: keep sensitive data out of your pipeline
Minimize fields, apply deliberate transformations, and test redaction through storage, viewers, and exports.
Web traffic logging: requests, routes, and real context
Build useful access logs while keeping observation points, latency boundaries, and visitor metrics distinct.
Structured JSON logging: design a schema that lasts
Define meaningful fields, preserve data types, and evolve your event schema without breaking downstream readers.
A security logging checklist for application teams
Capture access decisions and administrative actions with safe attribution, protected records, and clear outcomes.
What is a log API? A practical developer’s guide
Understand logging libraries, ingestion endpoints, and query interfaces—and build an event contract that connects them.

Explore by topic.
Structured logging
Build predictable events with named fields, stable types, and meaningful units. These articles explain how the shape of a record affects validation, querying, redaction, and long-term maintainability.
Read related notes →API design
Separate application interfaces, ingestion contracts, and query responsibilities. Explore decisions about schema evolution, acceptance, partial failure, and duplicate handling before choosing a transport.
Read related notes →AI observability
Connect the operational stages around a model call. Read about metadata, configuration versions, trace relationships, and usage provenance without treating prompt retention as the default.
Read related notes →Data protection
Reduce unnecessary collection and control where sensitive information can travel. These guides cover allowlists, transformation boundaries, safe access, and synthetic tests for overlooked copies.
Read related notes →Token usage
Understand the difference between estimated and reported usage. Learn how attempt identifiers, incomplete measurements, category mappings, and versioned assumptions affect resource accounting.
Read related notes →Tracing
Connect events without losing the boundaries between operations. Explore request correlation, child stages, timing definitions, and the honest treatment of missing or sampled observations.
Read related notes →HTTP logs
Design access records that explain routes, response outcomes, and latency. Keep edge, proxy, and application perspectives distinct, and avoid confusing infrastructure requests with individual visitors.
Read related notes →Security events
Record actions and decisions in a vocabulary investigators can understand. Preserve observed facts, permission boundaries, and final outcomes while keeping detections separate from proof of compromise.
Read related notes →Firewall logs
Investigate rule matches with their original source, action, and request context intact. Review how normalization, multiple matches, and export delivery affect the conclusions a dashboard can support.
Read related notes →Log ingestion
Follow an event through buffers, retries, acknowledgments, and durable storage. Define measurable limits and test duplicate delivery, overload, replay, and shutdown rather than assuming the happy path is sufficient.
