Microservices

Observability for
distributed systems

When a request touches 10 services, debugging gets hard. Loggy gives you distributed tracing, centralized logs, and service maps to understand exactly what's happening in your microservices.

The challenges of microservices

Microservices bring flexibility, but they also bring complexity. Here's how Loggy helps.

Problem: "Where did the request fail?"

A request touches 8 services. One of them returned an error. Which one? You're digging through logs from each service trying to correlate timestamps.

Solution: Distributed Tracing

See the entire request flow in one waterfall view. Failed spans are highlighted in red.

Problem: "Why is this endpoint slow?"

Your /api/checkout endpoint takes 3 seconds. Is it the payment service? The inventory check? The database? You have no idea where the time is going.

Solution: Span Timing

Each span shows its duration. See exactly which service or operation is the bottleneck.

Problem: "Logs are scattered everywhere"

Each service has its own logs. To debug one request, you're opening 5 different log files and trying to match up timestamps.

Solution: Log Correlation

All logs include trace IDs. View all logs for a request in one place, automatically correlated.

Problem: "What calls what?"

Your architecture has grown organically. You're not even sure which services depend on which anymore. Documentation is outdated.

Solution: Service Maps (Team)

Auto-generated service dependency graphs based on actual traffic. Always up to date.

How it works

Add tracing to your services in three simple steps.

1

Install the SDK

Add @loggydev/loggy-node to each service. One npm install.

npm install @loggydev/loggy-node
2

Add the middleware

One line of code to automatically trace all HTTP requests.

app.use(tracingMiddleware)
3

View in dashboard

Traces appear in your Loggy dashboard with full waterfall views.
