## Community Resources

The [nodejs-opentelemetry-tempo][tempo] project illustrates the use of
OpenTelemetry (through automatic and manual instrumentation) involving
microservices with DB interactions. It uses the following:

- [Prometheus](https://prometheus.io), for monitoring and alerting
- [Loki](https://grafana.com/oss/loki/), for distributed logging
- [Tempo](https://grafana.com/oss/tempo/), for distributed tracing
- [Grafana](https://grafana.com/grafana/) for visualization

For more details, visit the [project repository][tempo].
