prometheus-to-sd

prometheus-to-sd is a simple component that can scrape metrics stored in prometheus text format from one or multiple components and push them to the Stackdriver

TL;DR;

$ helm install stable/prometheus-to-sd

Prerequisites

• a service exposing metrics in prometheus format
• k8s cluster should run on GCE or GKE

Installing the Chart

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

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

The command deploys prometheus-to-sd 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.

Configuration

The following tables lists the configurable parameters and their default values.

Parameter	Description	Default
image.repository	prometheus-to-sd image repository	gcr.io/google-containers/prometheus-to-sd
image.tag	prometheus-to-sd image tag	v0.2.2
image.pullPolicy	Image pull policy	IfNotPresent
resources	CPU/Memory resource requests/limits	{}
port	Profiler port	6060
metricSources	Sources for metrics in the next format: component-name:http://host:port?whitelisted=a,b,c	{}
nodeSelector	node labels for pod assignment	{}

For more information please refer to the prometheus-to-sd documentation.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
  --set "metricsSources.kube-state-metrics=http://kube-state-metrics:8080" \
    stable/prometheus-to-sd

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-to-sd

Multiple metrics sources can be defined.
