spotinst-metrics-exporter

A prometheus exporter for metrics from Spotinst.

Current features

• Ocean AWS cost metrics for ocean clusters, namespaces and workloads
• Ocean AWS resource suggestions ("right sizing") for workloads and their containers

Building

Run make build to build a local binary, or make docker-build to build a docker image.

Configuration

The spotinst-metrics-exporter requires the SPOTINST_ACCOUNT and SPOTINST_TOKEN environment variables to be set. Furthermore you can configure the listen address via the --listen-address flag.

The exporter will listen on 0.0.0.0:8080 by default and exposes prometheus metrics at /metrics and a health endpoint at /healthz.

Deployment

The helm chart provided in this repository can be used to deploy the metrics exporter.

First, add the helm repository:

helm repo add spotinst-metrics-exporter \
  https://bonial-international-gmbh.github.io/spotinst-metrics-exporter

Create a values.yaml and add a spotinst section with the account ID and token, for example:

---
spotinst:
  account: act-12345678
  token: the-spotinst-token

For more helm configuration options have a look into the values.yaml defaults.

Finally use helm to install the metrics exporter:

helm upgrade spotinst-metrics-exporter spotinst-metrics-exporter/spotinst-metrics-exporter \
  --install --namespace kube-system --values values.yaml

Alternatively, you can also pass spotinst.account and spotinst.token to the helm command directly instead of using a values.yaml file:

helm upgrade spotinst-metrics-exporter spotinst-metrics-exporter/spotinst-metrics-exporter \
  --install --namespace kube-system \
  --set spotinst.account=act-12345678,spotinst.token=the-spotinst-token

Metrics

All metrics are gauge values. The values of CPU metrics are in milli-CPU, memory values are in MiB and cost values are in $USD. Cost metrics display the running costs of the current month and are reset on every 1st.
