Cloudwatch exporter

Linux

Windows

The Cloudwatch exporter is used to extract values from the AWS Cloudwatch for consolidated display in the VIMON.

Configuration

The exporter itself is then configured via vimon/config/cloudwatch_exporter/cloudwatch_exporter.yml.

The region for the query must be configured here and the metrics that are to be queried must also be activated.

Limit yourself to the metrics that are actually required, as otherwise a large number of requests may be made. These requests are billed by AWS if they exceed the free limit.

It should also be noted that CW does not continuously update the data. Querying every 15s is not recommended, as it accelerates reaching the free limit.

The interval for this scrape job should therefore be reduced in the Prometheus configuration, for example:

  - job_name: 'AWS'
    scrape_interval:      300s
    static_configs:
      - targets: ['foo.bar.com:9235']
        labels:
          app: 'aws'
          project: 'vimon'
          part: 'cloudwatch'
          stage: 'prod'
          host: 'foo.bar.com'

AWS-Auth

A role must be set up for this in AWS.

This role should only have the rights to view the data.

The AccessKey must then be stored under ~/.aws/credentials (the AWS CLI config).
