Prometheus

Prometheus, a Cloud Native Computing Foundation project, is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if some condition is observed to be true.

TL;DR;

$ helm install stable/prometheus

Introduction

This chart bootstraps a Prometheus deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.3+ with Beta APIs enabled

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/prometheus

The command deploys Prometheus on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Prometheus 2.x

Prometheus version 2.x has made changes to alertmanager, storage and recording rules. Check out the migration guide here

Users of this chart will need to update their alerting rules to the new format before they can upgrade.

Upgrading from previous chart versions.

As of version 5.0, this chart uses Prometheus 2.1. This version of prometheus introduces a new data format and is not compatible with prometheus 1.x. It is recommended to install this as a new release, as updating existing releases will not work. See the prometheus docs for instructions on retaining your old data.

Example migration

Assuming you have an existing release of the prometheus chart, named prometheus-old. In order to update to prometheus 2.1 while keeping your old data do the following:

1. Update the prometheus-old release. Disable scraping on every component besides the prometheus server, similar to the configuration below:

   alertmanager:
     enabled: false
   alertmanagerFiles:
     alertmanager.yml: ""
   kubeStateMetrics:
     enabled: false
   nodeExporter:
     enabled: false
   pushgateway:
     enabled: false
   server:
     extraArgs:
       storage.local.retention: 720h
   serverFiles:
     alerts: ""
     prometheus.yml: ""
     rules: ""

2. Deploy a new release of the chart with version 5.0+ using prometheus 2.x. In the values.yaml set the scrape config as usual, and also add the prometheus-old instance as a remote-read target.

   :
   .
   :
   d
   .

   Old data will be available when you query the new prometheus instance.

Configuration

The following table lists the configurable parameters of the Prometheus chart and their default values.
