Display Broker and Brokerset Information in Orion UI

[yisheng-zhou]

This update enables Orion to store and display metrics for brokers and brokersets within the Orion interface.

Details

Broker Class

• Introduces two new maps:
  • rawBrokerStatus: Stores raw data from the metrics API call as a map of String -> Double. Example: cpu_usage -> 0.22.
  • brokerStatus: Contains the keys and values that are displayed in the Orion UI. Both values are strings. Example: "CPU Usage" and "22%".

Brokerset Class

• Also includes two new maps:
  • rawBrokersetStatus: Stores raw data after aggregating values across all brokers as a map of String -> Double. Example: max_cpu_usage -> 0.22.
  • brokersetStatus: Contains the keys and values to be shown in the Orion UI. Both values are strings. Example: "Max CPU Usage Across All Brokers" and "22%".

BrokerMetricsSensor Class

• This class will be overridden by a sensor from the internal package.
• The sensor is intended to periodically call metrics APIs, such as the CloudWatch API, and update the rawBrokerStatus.

JavaScript Changes

• Multiple JavaScript updates were made to display the information.
• The Brokersets page in the Service section will show:
  • Maximum CPU usage over 7 days.
  • Maximum disk usage over 7 days for all brokers.

Testing

• The changes have been successfully tested within Pinterest.
