Error when connecting Prometheus Datasource

Grafana Prometheus
1

Hi guys,

I am new to both Grafana and Prometheus.
I am using Grafana 10.2.3 on MacOS (Ventura 13.2.1), with Prometheus 2.49.1

I am trying to connect a new Prometheus datasource from a custom exporter.

I was abled to successfully create a datasource from the default Prometheus job.
I am trying to do the same with a custom exporter and I have added a new scrape_config to the prometheus.yml as follows.

  • job_name: “test”
    static_configs:
    • targets: [“localhost:64502”]

However when I try to do add it as a data source and try to save and test, I get the following error.

ReadObject: expect { or , or } or n, but found #, error found in #1 byte of …|# HELP pyth|…, bigger context …|# HELP python_gc_objects_collected_total Objects co|… - There was an error returned querying the Prometheus API.

I can provide more details if needed.

Can you please help me figure out what I am doing wrong?

Thanks in advance!

Grafana Prometheus datasource should be connected to Prometheus server, not to Prometheus exporter.
