 // Prober is an HTTP prober that periodically sends out HTTP requests to specified
 // endpoints and reports if the returned results match the expectations. The results
 // of the probe, including latency, are recored in InfluxDB using the Carbon protocol.
 // See probers.json as an example of the config file format.
