Collected Data

For integration into a Prometheus system, the PDU can output all measurements in a Prometheus-
compatible format that can be queried in specific exposition format from the URL: 'https://<PDU_IP>/
cgi-bin/dump_prometheus.cgi'. The URL has one optional parameter, "include_names=1", to include
PDU, inlet and outlet names in the metric labels.
You can use cURL as follows to retrieve the data:
1. curl -k https://username:password@[PDU_IP]/cgi-bin/dump_prometheus.cgi
2. curl -k https://username:password@[PDU_IP]/cgi-bin/dump_prometheus.cgi?include_names=1
