Embedded Prometheus Stack¶

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

We provide defaults that were fine-tuned for low-noise and out-of-the-box integration with Robusta playbooks.

Default alerts were tested on the following clusters, to identify and remove false positives:

Alerts are based on excellent work done in the kubernetes-mixin project, with additional modifications by Robusta.

Enabling the Embedded Prometheus¶

By default, Robusta is installed without Prometheus and without default alerts. To enable them:

enablePrometheusStack: true

This setting is recommended if don't have Prometheus installed on your cluster.

Prometheus retention period¶

Robusta UI uses Prometheus data for showing graphs. To keep storage usage low, Prometheus keeps the data only for 14-15 days.

To change how long Prometheus saves the data, set the retention in your generated_values.yaml file:

prometheus:
  prometheusSpec:
    retention: 15d

If you're not using Robusta's embedded Prometheus, refer to the official Prometheus docs for documentation on retention periods.
