{
    "prometheus_exporters": {
        "default": [
            {
                "job": "node-exporter",
                "port": 9100
            }
        ],
        "etcd": [
            {
                "job": "node-exporter",
                "port": 9100
            },
            {
                "job": "etcd-exporter",
                "port": 2379
            }
        ],
        "postgresql": [
            {
                "job": "node-exporter",
                "port": 9100
            },
            {
                "job": "postgresql-exporter",
                "port": 9187
            }
        ],
        "vault": [
            {
                "job": "vault-exporter",
                "scheme": "https",
                "metrics_path": "/v1/sys/metrics",
                "params": {
                    "format": [
                        "prometheus"
                    ]
                },
                "port": 8200
            }
        ]
    }
}

Each role can have multiple jobs (one target per job is generated)

If role is not found, the default entry is used

Usage

The plugin exposes a single API endpoint (no web UI):

GET /api/plugins/prometheus-http-sd/targets/

Device or Virtual Machine is included only if all of the following are true:

1. It has status active
2. The custom field role is present and non‑empty

Metrics labels

Labels:

• job – Prometheus job name defined in the mapping
• __meta_netbox_name – object name
• __meta_netbox_type – device or vm
• __meta_netbox_cf_<custom_field> – every custom field prefixed with __meta_netbox_cf_
