ovh-exporter

Prometheus exporter for the OVH API.

Configuration

To generate a unique link on the OVH Api Portal with the correct OVH permissions needed for this project, run:

ovh-exporter credentials

Alternatively, you can use Go:

go run cmd/ovh-exporter/main.go credentials

Once you have the credentials, create a ovh-exporter.env file containing the following variables:

export OVH_ENDPOINT="ovh-eu"
export OVH_APP_KEY=""
export OVH_APP_SECRET=""
export OVH_CONSUMER_KEY=""
export OVH_CLOUD_PROJECT_INSTANCE_BILLING_PROJECT_IDS=""
export OVH_CACHE_UPDATE_INTERVAL="300"
export SERVER_PORT="8080"

To use the compose, add a ovh-exporter.env file at the root of your project with the variables filled in:

OVH_ENDPOINT="ovh-eu"
OVH_APP_KEY=""
OVH_APP_SECRET=""
OVH_CONSUMER_KEY=""
OVH_CLOUD_PROJECT_INSTANCE_BILLING_PROJECT_IDS=""
OVH_CACHE_UPDATE_INTERVAL="300"
SERVER_PORT="8080"

The projects' id can be found in the Public Cloud tab of OVH console.

Running

Running the Binary

Developer Guide

Adding New Metrics

Follow these steps to add new metrics:

1. Add the required routes in pkg/credentials/generate for the OVH API Token.
2. Add the API calls in ovhsdk/api. Create a new file for each route.
3. Define the models in ovhsdk/models based on the schema from the API responses.
4. Create the metric in pkg/networks and write the necessary custom code.
5. Update the initialization functions in pkg/network/serve.go by adding your functions to initializeMetrics() and updateMetrics().

Once you've added the metric, test it by running the Compose file. If needed, set up port forwarding, and then run the following command:

curl -s 0.0.0.0:<port>/metrics | grep "your_metric"

Example

curl -s 0.0.0.0:8080/metrics | grep "ovh_exporter_services_savingsplans_subscribed"
