Use the Grafana integration to visualize time series data.

The following diagram shows the time series metrics dataflow between the Cortex Data Lake to the Grafana server:

Version compatibility

Supported Grafana version: 7.5.0 or later.


  • OpsRamp API available
  • OpsRamp OAuth2 API Credentials from OpsRamp integrations page and Client Unique ID
  • Installed Grafana


Per unique metric series, a maximum of 11000 datapoints can be scraped, per interval. For example, the metrics aws_ec2_cpu_utilization{host=lab1,region=us-east-1} and aws_ec2_cpu_utilization{host=dev2, region=us-east-2a} are both novel metric series. We support 11000 datapoints, or instances, of these metrics, per scrape.

Create and configure data source

  1. Log in to the Grafana server with your Grafana login credentials.
  2. Configure the data source using the configuration editor:
