Trigger Specification

This specification describes the new-relic trigger that scales based on a New Relic metric.

triggers:
  - type: new-relic
    metadata:
      # Required: Account - Subaccount to run the query on
      account: '1234567'
      # Required: QueryKey - Api key to connect to New Relic
      queryKey: "NRAK-xxxxxxxxxxxxxxxxxxxxxxxxxxx"
      # Optional: nrRegion - Region to query data for. Default value is US.
      region: "US"
      # Optional: noDataError - If the query returns no data should this be treated as an error. Default value is false.
      noDataError: "true"
      # Required: nrql
      nrql: "SELECT average(duration) from Transaction where appName='SITE'"
      # Required: threshold
      threshold: "50.50"
      # Optional: activationThreshold - Target value for activating the scaler.
      activationThreshold: "20.1"

Parameter list:

account - The account within New Relic that the request should be targeted against.
queryKey - The API key that will be leveraged to connect to New Relic and make requests. official documentation
region - The region to connect to for the New Relic apis. (Values: LOCAL, EU, STAGING, US, Default: US, Optional)
noDataError - Should queries that return nodata be treated as an error, if set to false and a query returns nodata, the result be 0. (Values: true, false, Default: false, Optional)
nrql - The New Relic query that will be run to get the data requested.
NOTE: The default New Relic time range for a query is last 30 minutes, which can produce unexpected responses. To mimic the behavior of a TIMESERIES query, you need to reduce the scope to 1 minute, this can be achieved by adding SINCE 1 MINUTE AGO to the query. official documentation official documentation
threshold - A threshold that is used as the targetValue or targetAverageValue (depending on the trigger metric type) in the HPA configuration. (This value can be a float)
activationThreshold - Target value for activating the scaler. Learn more about activation here.(Default: 0, Optional, This value can be a float)

Authentication Parameters

You can use TriggerAuthentication CRD to configure the authentication with a queryKey.

Authentication:

queryKey - The API key that will be leveraged to connect to New Relic and make requests. official documentation
account - The account within New Relic that the request should be targeted against. This can be used to replace the value that would be provided in the trigger.
region - The region to connect to for the New Relic apis. This can be used to replace the value that would be provided in the trigger.
