Netra Custom Metrics

Use this skill to instrument business and operational KPIs alongside Netra traces.

When To Use

• You need request, latency, token, and cost metrics.
• You need queue depth or in-flight gauges.
• You want periodic metrics export via OTLP/HTTP JSON.

Procedure

1. Initialize Netra with enable_metrics=True.
2. Get a meter via Netra.get_meter("service-name").
3. Define instruments: counter, histogram, up-down counter, observable counter.
4. Record values with low-cardinality attributes.
5. Call Netra.shutdown() on process exit to flush final export.

Python Pattern

from netra import Netra
