QA：Do jmx_prometheus_httpserver scrapy data from jmx server proactively when without prometheus？

[hanson2021]

When i only start jmx_prometheus_httpserver ,whether it will proactively scrapy data or not? If it will, is there any configure to control frequency？

[fstab]

No, it's just callbacks waiting for the Prometheus server to scrape. If the metrics endpoint is not called, nothing will happen.

Can we have an option to enable active scraping at certain intervals? That way we can remove the dependency on the Prometheus server and jmx_exporter be used as a standalone tool.

[fstab]

I think I don't understand your question. What are you trying to achieve? You need a Prometheus server to do Prometheus monitoring, right?

[mustajibmk]

Most of the time, yes we would have a Prometheus server which would do it for us. I was referring to the case where jmx_exporter was not being called by the Prometheus server but rather by custom Java code/application.

[dhoard]

The JMX exporter exposes a REST API to collect metrics from JMX MBeans. Each REST API call collects metrics and returns a metrics response.

The application (Prometheus, custom application, etc.) calling the REST API doesn't matter.

The scraping interval is a function of the application calling the REST API.
