prometheus receiver

The prometheus receiver can be used to scrape the metrics of a single prometheus client. It does not use any official Golang library but making simple HTTP get requests and parse the response.

Configuration structure

{
  "<name>": {
    "type": "prometheus",
    "address" : "testpromhost",
    "port" : "12345",
    "port" : "/prometheus",
    "interval": "5s",
    "ssl" : true,
  }
}
  • type: makes the receiver a prometheus receiver
  • address: Hostname or IP of the Prometheus agent
  • port: Port of Prometheus agent
  • path: Path to the Prometheus endpoint
  • interval: Scrape the Prometheus endpoint in this interval (default '5s')
  • ssl: Use SSL or not

The receiver requests data from http(s)://<address>:<port>/<path>.
