This option was removed. The URL of the endpoint serving JSON
must now be provided to the exporter by prometheus via the url
parameter <literal>target</literal>.
In prometheus a scrape URL would look like this:
<programlisting>
http://some.json-exporter.host:7979/probe?target=https://example.com/some/json/endpoint
</programlisting>
For more information, take a look at the <link xlink:href="https://github.com/prometheus-community/json_exporter">
