Prometheus - Monitoring System & Time Series Database

Overview

Kolla can deploy a full working Prometheus setup in either a all-in-one or multinode setup.

Preparation and deployment

To enable Prometheus, modify the configuration file /etc/kolla/globals.yml and change the following:

enable_prometheus: "yes"

Extending the default command line options

It is possible to extend the default command line options for Prometheus by using a custom variable. As an example, to set remote timeouts to 30 seconds and data retention period to 2 days:

prometheus_cmdline_extras: "-storage.remote.timeout 30s -storage.local.retention 48h"
