prometheus digitalocean service discovery

prometheus-digitalocean-sd

Uses DigitalOcean's API to generate a file_sd_config's compatible JSON file, so you can service discovery DigitalOcean droplets on Prometheus.

Usage

You can run it as docker container:

docker run \
  -v "$PWD":/tmp \
  -e DO_TOKEN="digitalocean-read-only-token" \
  --restart=always \
  totvslabs/prometheus-digitalocean-sd --output.file=/tmp/do_sd.json

And then change your prometheus.yml config file to use file_sd_configs to read the do_sd.json file:

scrape_configs:
  - job_name: 'node'
    file_sd_configs:
      - files: ['do_sd.json']
        refresh_interval: 30s
    relabel_configs:
      - source_labels: [__meta_do_status]
        regex: active
        action: keep
      - source_labels: [__meta_do_region]
        target_label: region
      - source_labels: [__meta_do_size]
        target_label: flavor
      - source_labels: [__meta_do_public_ip]
        target_label: ip
      - source_labels: [__meta_do_name]
        target_label: instance_name

File format

The JSON file will have the following format and labels:

[
	{
		"targets": [
			"1.2.3.4:9100"
		],
		"labels": {
			"__meta_do_az": "sfo1",
			"__meta_do_id": "1234",
			"__meta_do_name": "droplet-name",
			"__meta_do_public_ip": "1.2.3.4",
			"__meta_do_size": "4gb",
			"__meta_do_status": "active"
		}
	},
	// all other droplets
]
