The prometheus json exporter is now managed by the prometheus community. Together with additional features
|
||||
some backwards incompatibilities were introduced.
|
||||
Most importantly the exporter no longer accepts a fixed command-line parameter to specify the URL of the
|
||||
endpoint serving JSON. It now expects this URL to be passed as an URL parameter, when scraping the exporter's
|
||||
<literal>/probe</literal> endpoint.
|
||||
In the prometheus scrape configuration the scrape target might look like this:
|
||||
<programlisting>
|
||||
http://some.json-exporter.host:7979/probe?target=https://example.com/some/json/endpoint
|
||||
</programlisting>
|
||||
</para>
|
||||
<para>
|
||||
Existing configuration for the exporter needs to be updated, but can partially be re-used.
|
||||
Documentation is available in the upstream repository and a small example for NixOS is available
|
||||
in the corresponding NixOS test.
|
||||
</para>
|
||||
<para>
|
||||
These changes also affect <literal>services.prometheus.exporters.rspamd</literal>, which is
|
||||
just a preconfigured instance of the json exporter.
