[question/request] output_metrics_options availability HTTP probe

[jbkc85]

To whom it may concern,

I was wanting to use output_metrics_options in the HTTP probe but apparently its only available in the external type. Is there a reason for this? I would love to be able to add additional tags to whatever probe type i can - specifically environment without having to write Prometheus regex labels.

Thanks!

ie:

  http_probe {
    protocol: HTTPS
    output_metrics_options {
      additional_labels: "environment=location1,service=example"
    }
  }

@jbkc85 If you're looking for output_metrics_options only for additional labels, there is another way to do it (though it's not released yet):

cloudprober/probes/proto/config.proto

Lines 100 to 112 in ee717b0

	// Additional labels to add to the probe results. Label's value can either be
	// static or can be derived from target's labels.
	//
	// Example:
	// additional_label {
	// key: "src_zone"
	// value: "{{.zone}}"
	// }
	// additional_label {
	// key: "src_zone"
	// value: "target.labels.zone"
	// }
	repeated AdditionalLabel additional_label = 14;

Though I understand that output_metrics_options can be useful for HTTP probes regardless in case you want to parse metrics from HTTP probe output.

I just released a new version v0.10.5 that has support for the additional_label field. Also added an example. Since this particular issue seems to be just about that, marking it closed. I've file a different feature request to build metrics from the HTTP probe output: #297.
