This directory contains a Docker Compose setup for running an observability stack to monitor Bottom with OpenTelemetry.
This directory contains a Docker Compose setup for running an observability stack to monitor Symon with OpenTelemetry.
## Architecture
The stack includes:
1. **OpenTelemetry Collector** - Receives metrics from Bottom via OTLP protocol
1. **OpenTelemetry Collector** - Receives metrics from Symon via OTLP protocol
2. **Prometheus** - Scrapes and stores metrics from the OTEL Collector
3. **Grafana** - Visualizes metrics from Prometheus
