Embedded Prometheus Stack¶

Robusta can install an embedded Prometheus stack with pre-configured alerts.

It includes defaults alerts that we fine-tuned in advance, as well as prebuilt Robusta playbooks.

This option is highly recommended, but disabled by default, as many users already have Prometheus installed.

To customize the bundled kube-prometheus-stack, explore the chart values.yaml file.

Enabling the Embedded Prometheus¶

Add to generated_values.yaml:

enablePrometheusStack: true

Apply the change by performing a Helm Upgrade.

By default, Prometheus stores data for 14-15 days.

You can modify retention times in generated_values.yaml:

prometheus:
  prometheusSpec:
    retention: 15d #change the number of days here

Apply the change by performing a Helm Upgrade.

To allow the Grafana dashboard to persist after the Grafana instance restarts, you could add to generated_values.yaml:

...
# Customize settings
kube-prometheus-stack:
  grafana:
    persistence:
      enabled: true

Apply the change by performing a Helm Upgrade.
