Unfragile

The request names promphp/prometheus_client_php, a PHP client library for exposing Prometheus metrics; none of the candidates is that library itself. Prometheus 1 is the monitoring system whose metrics such a client feeds, and OpenTelemetry 5 is a vendor-neutral telemetry framework that exports to Prometheus among other backends. Packagist 4 is the PHP package repository where the library is distributed.
