[patsevanton]

May be project have switch: enable/disable wavefront?

[arey]

I am in favor of the possibility of disabling wavefront on the k8s profile. Could you work on this idea?

[patsevanton]

I try to disable wavefront by issue wavefrontHQ/wavefront-spring-boot#57

In https://github.com/spring-petclinic/spring-petclinic-cloud/blob/master/k8s/api-gateway-deployment.yaml use SPRING_PROFILES_ACTIVE - kubernetes

cat spring-petclinic-api-gateway/src/main/resources/bootstrap.yml

May be i incorrect add management.metrics.export.wavefront.enabled=false ?

[patsevanton]

May be create issue in https://github.com/wavefrontHQ/wavefront-spring-boot ?

[snicoll]

I think we should keep this conversation here. The configuration to disable the endpoint should be read soon enough (that is not via configuration server). How is this configuration file loaded ?

[patsevanton]

@snicoll I am sorry. I am DevOps engineer. Where i can find configuration file ?

[snicoll]

@patsevanton sorry I've noticed that you did answered my question already. I am not sure bootstrap.yml is the best place for this. See also the issue I've created.

[patsevanton]

any news?

[arey]

Yes see #43
