php-fpm_exporter is a Prometheus exporter for PHP-FPM metrics.

TL;DR;

helm install stable/prometheus-php-fpm-exporter

Introduction

This chart bootstraps a php-fpm_exporter deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

Kubernetes 1.8+ with Beta APIs enabled

Installing the Chart

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

helm install --name my-release stable/prometheus-php-fpm-exporter

The command deploys prometheus-php-fpm-exporter on the Kubernetes cluster in the default configuration.

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.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

helm install --name my-release -f values.yaml stable/prometheus-php-fpm-exporter
