Just seein php_version as a metric version

I installed your plugin by first download the current master, made composer update -o. Than I zipped the hole folder and uploaded it by using the interface of WP.

Did I reproduce anything of your documentation wrong?

I just don't see any other metric than this:

I hope, you can help me.

Meta:
WP Version: 6.2

Okay, as far as I see, a admin has to define define('PROMETHEUS_METRICS_FOR_WP_DISABLE_CACHE', 'true') within the wp-config.php, I would add this to the readme?

That constant disable the transient that cache daily the metrics

Prometheus-Metrics-in-WordPress/prometheus-metrics-for-wp.php

Line 123 in 414a7b0

    
           if ($metrics && (!defined('PROMETHEUS_METRICS_FOR_WP_DISABLE_CACHE') || !PROMETHEUS_METRICS_FOR_WP_DISABLE_CACHE)) {

and regenerate everything at every call.

@cgomm As it is only possible to send numeric values, ~~I've added the actual PHP Version as a "version" label...~~ The Prometheus Client library has this as default metric included.

But it would be a good idea to just send the PHP_VERSION_ID as the actual value.
