I want to publish all info that is already on /actuator/health to /actuator/prometheus, since the /actuator/prometheus endpoint doesn't contain metrics about the disk space or LDAP/database availability. I found that one can make a DiskSpaceMetricsConfiguration class (https://www.ivankrizsan.se/2021/01/23/spring-boot-prometheus-disk-space-metrics), and that works, but I can't figure out how to do the same for app status, db status, and ldap status.

I'm using spring-boot 2.1.9, spring-boot-starter-actuator 2.5.1, and micrometer-registry-prometheus 1.2.1.

The versions you are using are not compatible with each other, please use the Spring Boot BOM, it will set the versions for you.

The Spring Boot documentation has a section about Mapping Health Indicators to Micrometer Metrics. You can do the same for each health indicator.

The trick here is converting a Health Indicator to a Gauge, you can do this in multiple ways, it is up to you, you can use 0/1 values to indicate if the service is UP or not or you can use different values for each status like the documentation above suggests.
