Prometheus configuration

Kiali uses Prometheus to generate the topology graph, show metrics, calculate health and for several other features. Prometheus is enabled by default and is required for full Kiali functionality.

Disabling Prometheus

If you want to run Kiali without a Prometheus instance, you can disable it:

spec:
 external_services:
 prometheus:
 enabled: false

When Prometheus is disabled, Kiali will still start and serve non-metrics features such as workload/service/app listing, Istio configuration, and mesh topology. However, the graph, metrics tabs, traffic tabs, and request-rate health will be unavailable. Health badges for workloads and apps will degrade to show only Kubernetes-level status (replica counts).

Production environments should not be using the Istio Prometheus add-on, or carrying over its configuration settings. That is useful only for small, or demo installations. Instead, Prometheus should have been installed in a production-oriented way, following the Prometheus documentation.

This page is primarily for users where Prometheus is being used specifically for Kiali, and possible optimizations that can be made knowing that Kiali does not utilize all of the default Istio and Envoy telemetry.
