Chapter 1. About Metering

Important

Metering is a deprecated feature. Deprecated functionality is still included in OpenShift Container Platform and continues to be supported; however, it will be removed in a future release of this product and is not recommended for new deployments.

For the most recent list of major functionality that has been deprecated or removed within OpenShift Container Platform, refer to the Deprecated and removed features section of the OpenShift Container Platform release notes.

1.1. Metering overview

Metering is a general purpose data analysis tool that enables you to write reports to process data from different data sources. As a cluster administrator, you can use metering to analyze what is happening in your cluster. You can either write your own, or use predefined SQL queries to define how you want to process data from the different data sources you have available.

Metering focuses primarily on in-cluster metric data using Prometheus as a default data source, enabling users of metering to do reporting on pods, namespaces, and most other Kubernetes resources.

You can install metering on OpenShift Container Platform 4.x clusters and above.

1.1.1. Installing metering

You can install metering using the CLI and the web console on OpenShift Container Platform 4.x and above. To learn more, see installing metering.

1.1.2. Upgrading metering

You can upgrade metering by updating the Metering Operator subscription. Review the following tasks:

  • The MeteringConfig custom resource specifies all the configuration details for your metering installation. When you first install the metering stack, a default MeteringConfig custom resource is generated. Use the examples in the documentation to modify this default file.
  • A report custom resource provides a method to manage periodic Extract Transform and Load (ETL) jobs using SQL queries. Reports are composed from other metering resources, such as ReportQuery resources that provide the actual SQL query to run, and ReportDataSource resources that define the data available to the ReportQuery and Report resources.

1.1.3. Using metering

You can use metering for writing reports and viewing report results. To learn more, see examples of using metering.

1.1.4. Troubleshooting metering

You can use the following sections to troubleshoot specific issues with metering.

  • Not enough compute resources
  • StorageClass resource not configured
  • Secret not configured correctly

1.1.5. Debugging metering

You can use the following sections to debug specific issues with metering.

  • Get reporting Operator logs
  • Query Presto using presto-cli
  • Query Hive using beeline
  • Port-forward to the Hive web UI
  • Port-forward to HDFS
  • Metering Ansible Operator

1.1.6. Uninstalling metering

You can remove and clean metering resources from your OpenShift Container Platform cluster. To learn more, see uninstalling metering.

1.1.7. Metering resources

Metering has many resources which can be used to manage the deployment and installation of metering, as well as the reporting functionality metering provides.

Metering is managed using the following custom resource definitions (CRDs):

MeteringConfig

Configures the metering stack for deployment. Contains customizations and configuration options to control each component that makes up the metering stack.

Report

Controls what query to use, when, and how often the query should be run, and where to store the results.

ReportQuery

Contains the SQL queries used to perform analysis on the data contained within ReportDataSource resources.

ReportDataSource

Controls the data available to ReportQuery and Report resources. Allows configuring access to different databases for use within metering.
