Depending on the monitoring solution you have in place and the SLIs you have configured for your services, you need to deploy the corresponding SLI-provider. In Keptn 0.9.x, this can be either Dynatrace or Prometheus.
Complete steps from section Install Dynatrace Keptn integration.
To configure Keptn to use Dynatrace SLIs for your project (e.g. musicshop), execute the following command:
keptn configure monitoring dynatrace --project=musicshop
Configure custom Dynatrace SLIs as explained here.
Complete steps from section Setup Prometheus SLI-provider.
To configure Keptn to use the Prometheus SLI-provider for your project (e.g. musicshop), execute the following command:
keptn configure monitoring prometheus --project=musicshop --service=catalogue
Configure custom SLIs for the Prometheus SLI-provider as explained here.
