Overview

The prober which is called when gathering metrics

Constant Summary collapse

DEPRECATED =

The stdout notice in #probe_db reaches whoever reads the exporter's log, which is not who reads the metrics. HELP is the one channel that travels with the sample to the scraper, so the deprecation rides there too: it survives into Prometheus and shows up in Grafana's metric browser.

"(deprecated, to be removed in a future major version)".freeze
REPLACEMENT =
