Monitoring - open-telemetry/opentelemetry-demo

Monitoring is an essential practice in ensuring the health and performance of deployed services. In the context of the project open-telemetry/opentelemetry-demo, various monitoring tools can be used. This explanation will cover the possible options and provide examples for each option, quoting the source of information to build confidence.

OpenTelemetry Collector

The OpenTelemetry Collector is a vendor-neutral, cross-platform data processor that collects, processes, and exports telemetry data (traces, metrics, and logs) from your application. It can be used to export data to various backends such as Jaeger, Zipkin, Prometheus, or vendor-specific backends.

To get started with the OpenTelemetry Collector, follow the instructions in the documentation: Getting Started with OpenTelemetry Collector.

Here’s an example of how to pull the OpenTelemetry Collector Docker image and run the collector in a container:

docker pull otel/opentelemetry-collector:0.88.0
docker run -p 127.0.0.1:4317:4317 -p 127.0.0.1:55679:55679 otel/opentelemetry-collector:0.88.0

Exporters

Exporters are used to send telemetry data to various backends. OpenTelemetry supports several exporters, including OTLP, Prometheus, and stdout.

To learn more about exporters and how to set them up in your code, refer to the documentation: Exporters in OpenTelemetry Python.

Prometheus

Prometheus is an open-source systems monitoring and alerting toolkit. To use Prometheus as a backend, you can configure the OpenTelemetry Collector to export data to Prometheus.

Here’s an example of how to configure the OpenTelemetry Collector to export data to Prometheus:

receivers:
otlp:
protocols:
grpc:

exporters:
prometheus:
port: 9090

processors:
batch:

service:
pipelines:
traces:
receivers: [otlp]
processors: [batch]
exporters: [prometheus]
metrics:
receivers: [otlp]
processors: [batch]
exporters: [prometheus]

Grafana

Grafana is an open-source platform for data visualization and monitoring. It can be used to visualize data from various backends, including Prometheus.

To learn more about using Grafana with OpenTelemetry, refer to the documentation: Grafana with OpenTelemetry.

OpenSearch and Elastic

OpenSearch and Elastic are open-source search and analytics engines. They can be used as a backend to store and analyze logs, metrics, and traces.

To learn more about using OpenSearch and Elastic with OpenTelemetry, refer to the documentation: OpenSearch and Elastic Integration.

AlibabaCloud LogService

AlibabaCloud LogService is a log service provided by Alibaba Cloud. It can be used as a backend to store and analyze logs.

To learn more about using AlibabaCloud LogService with OpenTelemetry, refer to the documentation: AlibabaCloud LogService Integration.

In conclusion, OpenTelemetry provides a wide range of monitoring tools and integrations to ensure the health and performance of your deployed services. By using OpenTelemetry Collector, exporters, Prometheus, Grafana, OpenSearch, Elastic, and AlibabaCloud LogService, you can collect, process, and visualize telemetry data from your application.
