SpringBoot Not able to disable exporting metrices to influxDB via application properties in sprint boot tests

I am using spring-boot-starter-actuator,micrometer-core and micrometer-registry-influx dependencies in my spring boot application.

Versions: spring boot starter - 2.7.7 micrometer version - 1.9.5 java - 17

I started noticing the errors in every test case which conveyed issues with InfluxMeterRegistry

I tried switching it off via application config:

management:
   metrics:
    export:
      influx:
        enabled: false

Additionally tried (just to make sure): @TestPropertySource(properties = "spring.metrics.export.influx.enabled=false")

But just can't seem to get rid off these errors. I searched everywhere and switching off influx should have done it, but I am not sure why it keeps on coming. I tried adding a DB name here to see if the configuration is working and I would get that DB name in the error, so yeah the configs are getting picked up just fine.

I double checked the configuration properties at play here and tried different combinations as well. But this error keeps on coming. I also made sure that there is no bean or configuration that is invoking InfluxMeterRegistry I tried adding a debug point to InfluxMeterRegistry at the time of it's creation and looks like InfluxConfig carried the configuration property as enabled.

@SpringBootTest should disable metrics export by default. From what you've described thus far I cannot tell why that isn't working. If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.

Hello. I found the root cause. The parent project, which also defines the dependency, had explicitly stated property influx.enabled=true I am not sure why I was not able to override this in my project, but removing it from the parent worked. I think this is not a bug and the issue can be closed.

Thanks for letting us know.
