Monitor Solr using prometheus and Grafana

Question

I think I am missing something here.

I installed prometheus[2.18 Darwin], Grafana[7.0]. I started solr exporter which is part of solr[8.1]. It started and didn't throw any error.

Then added prometheus as a data source in grafana. I added job name and solr url in scrape section.

scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries   
scraped from this config.
- job_name: 'solr'

# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.

static_configs:
- targets: ['localhost:9854']

When I see localhost:9854/graph it gives me the metrics. It is prometheus url. I tried to load JSON in contrib/prometheus-exporter/conf to Grafana.

It shows cannot read property 'result' of undefined

How do I link all these three? I followed solr reference guide and few GitHub links. But I don't have much knowledge about prometheus and Grafana. I want to see solr metrics.

I see this in grafana log.

I started Solr-exporter using ./bin/solr-exporter -p 9854 -b http://localhost:8983/solr -f ./conf/solr-exporter-config.xml &

Try adding the metrics-path as '/' in the prometheus yml config

 - job_name: 'Solr'
    metrics_path: '/'
    static_configs:
      - targets: ['localhost:9854']
      - labels :
          group: core
