[Prometheus JMX Exporter] Help needed: Export String metric as labels

[Guowei Zhang]

Hi master,
I have a Spring application with a Bean which has two variables: one is String and another one is Integer.
I use org.springframework.jmx.export.annotation.ManagedResource and org.springframework.jmx.export.annotation.ManagedAttribute to expose them to JMX,
and then use jmx_prometheus_javaagent-0.17.0.jar to collect these custom metrics.
The result is that Integer metric is collected, but String metric not.
Then I read the source code of prometheus/jmx_exporter, it seems like that String is not supported yet.
My question: Is there any way to expose String metric as labels of Integer metric (without code modification, just change configuration of Spring and JMX exporter)?
Thank you!
