Modern applications generate thousands of logs every day, but teams still struggle to find issues quickly. Traditional log monitoring often involves searching manually through CloudWatch, jumping between services, and spending valuable time correlating events.
LogInSight solves this problem by centralizing log ingestion, organizing logs in a lightweight backend, and offering instant analytics through a clean, interactive dashboard.
This article explains how LogInSight improves debugging efficiency and how the system works from log ingestion to real-time insights
How LogInSight Improves the Business
Centralized Log Visibility
Instead of toggling between multiple CloudWatch log groups, LogInSight brings everything into a unified dashboard.
Faster Debugging and Issue Detection
Engineers can instantly view errors, warnings, request failures, and event spikes without manually filtering logs.
Better Operational Insights
Log analytics, error frequency charts, timestamps, and stream summaries help teams understand system behavior at a glance.
Lightweight and Cost-Efficient
LogInSight uses Python, FastAPI, SQLite, and Streamlit—keeping hosting and maintenance extremely simple.
Real-Time Awareness
AWS log polling enables near real-time updates, helping teams react before issues escalate.
Log Ingestion from AWS CloudWatch
LogInSight connects to CloudWatch using AWS SDKs and pulls logs from configured log groups.The ingestion pipeline:
- Retrieves logs in batches
- Converts raw streams into structured JSON
- Stores processed entries in a local SQLite database
- Categorizes logs by service, level, and timestamp
This creates a consolidated log source that is easier to search and analyze.
Future-Ready: From Static Logs to Live Log Streaming
The current version of LogInSight is built to process static CloudWatch log batches, but the architecture is designed to scale into a real-time log streaming system with minimal changes.
By integrating:
- AWS Lambda to trigger whenever new CloudWatch logs arrive
- Amazon Kinesis to stream logs continuously
- A Python log consumer to process live data
- Streamlit to update the dashboard automatically
LogInSight can evolve into a fully real-time observability platform, delivering instant insights during outages, deployments, or high-traffic periods.
Structured Storage With SQLite
- Logs are stored in a clean and lightweight schema:
- Log message
- Timestamp
- Log level (INFO, WARN, ERROR)
- Service / log group
Additional metadata
SQLite keeps the system simple, fast, and portable—ideal for teams that want quick deployment without heavy infrastructure.
Backend API Powered by FastAPI
FastAPI serves as the analytics engine behind LogInSight.The API provides endpoints for:
- Fetching logs based on filter criteria
- Searching logs by keywords
- Retrieving error summaries
- Fetching time-series data for charts
- Providing service-wise log breakdowns
This backend ensures low-latency responses even with large log volumes.
Real-Time Analytics Dashboard (Streamlit)
The interactive dashboard gives teams a clear, actionable view of system health. It includes:
- Live log stream viewer
- Error and warning frequency charts
- Service-level log summaries
- Time-based filtering
- Search and pattern matching
- Highlighting for critical log events
This enables teams to pinpoint issues instantly and understand trends with minimal effort.
