Prise en charge d’Amazon SQS avec AWS Lambda

Pour surveiller les flux de données pour les fonctions Lambda Node.js appelant Amazon SQS, SNS ou Kinesis, utilisez le traceur Lambda Node.js de Datadog, datadog-lambda-js v.12.128.0 ou version ultérieure.

Installation

Node.js utilise l’auto-instrumentation pour injecter et extraire les métadonnées supplémentaires requises par Data Streams Monitoring pour mesurer les latences de bout en bout et les relations entre les files d’attente et les services. Pour activer Data Streams Monitoring, définissez la variable d’environnement DD_DATA_STREAMS_ENABLED sur true sur les services envoyant des messages à votre technologie de streaming (ou en consommant).

Exemple :

environment:
    - DD_DATA_STREAMS_ENABLED: 'true'
    - DD_TRACE_REMOVE_INTEGRATION_SERVICE_NAMES_ENABLED: 'true'

Monitoring Kafka Pipelines

Data Streams Monitoring uses message headers to propagate context through Kafka streams. If log.message.format.version is set in the Kafka broker configuration, it must be set to 0.11.0.0 or higher. Data Streams Monitoring is not supported for versions lower than this.

Monitoring SQS pipelines

Data Streams Monitoring uses one message attribute to track a message’s path through an SQS queue. As Amazon SQS has a maximum limit of 10 message attributes allowed per message, all messages streamed through the data pipelines must have 9 or fewer message attributes set, allowing the remaining attribute for Data Streams Monitoring.

Monitoring RabbitMQ pipelines

The RabbitMQ integration can provide detailed monitoring and metrics of your RabbitMQ deployments. For full compatibility with Data Streams Monitoring, Datadog recommends configuring the integration as follows:

instances:
  - prometheus_plugin:
      url: http://<HOST>:15692
      unaggregated_endpoint: detailed?family=queue_coarse_metrics&family=queue_consumer_count&family=channel_exchange_metrics&family=channel_queue_exchange_metrics&family=node_coarse_metrics

This ensures that all RabbitMQ graphs populate, and that you see detailed metrics for individual exchanges as well as queues.

Monitoring SNS-to-SQS pipelines

To monitor a data pipeline where Amazon SNS talks directly to Amazon SQS, you must enable Amazon SNS raw message delivery.

Monitoring Kinesis pipelines

There are no message attributes in Kinesis to propagate context and track a message’s full path through a Kinesis stream. As a result, Data Streams Monitoring’s end-to-end latency metrics are approximated based on summing latency on segments of a message’s path, from the producing service through a Kinesis Stream, to a consumer service. Throughput metrics are based on segments from the producing service through a Kinesis Stream, to the consumer service. The full topology of data streams can still be visualized through instrumenting services.

Instrumentation manuelle

Data Streams Monitoring propage le contexte via les en-têtes de messages. Si vous utilisez une technologie de file d’attente non prise en charge par DSM, une technologie sans en-têtes (comme Kinesis) ou des Lambdas, utilisez l’instrumentation manuelle pour configurer DSM.

Surveillance des connecteurs

Connecteurs Confluent Cloud

Data Streams Monitoring can automatically discover your Confluent Cloud connectors and visualize them within the context of your end-to-end streaming data pipeline.

Setup

1. Install and configure the Datadog-Confluent Cloud integration.

2. In Datadog, open the Confluent Cloud integration tile.

   

   Under Actions, a list of resources populates with detected clusters and connectors. Datadog attempts to discover new connectors every time you view this integration tile.

3. Select the resources you want to add.

4. Click Add Resources.

5. Navigate to Data Streams Monitoring to visualize the connectors and track connector status and throughput.
