Results of monitoring of indexer in Grafana is empty

[shusterboris]

Dear colleagues!
I am new to Grafana. I tried to run Docker container as recommended here: https://github.com/OpenGrok/opengrok-monitoring-docker
It worked after adding fallback_scrape_protocol: 'PrometheusText0.0.4' to prometheus.yml and fixing data source in indexer dashboard. But indexer dashboard shows nothing even if indexer runs for 1 hour or more.
And does it work for you?

The silence of the Universe... Ok. To show the results we need to change expression in dashboard settings or indexer.yml. Values of "expr" attributes should be accordingly: rate(process_cpu_seconds_total[1m]) * 100 for CPU, go_threads for threads, indexer_jvm_memory_used for heap memory. Data source should be set Prometheus in the dashboard settings, or you need add variable DS_PROMETHEUS = Prometheus in dashboard settings
