Promethues | 一款以古希腊为背景的休闲小游戏 | Game Engine library

You could change your code like this and make sure you have added the port 8001,8000 in the inbound rule of your NSG associated to the Ubuntu VM.

As a workaround for deployments it appears that the metrics have to be exported from pods IN the target deployment.

To get this working I had to move the prometheus-to-sd container to the deployment I wanted to scale and then scrape the exposed metrics from Redis-Exporter in the Redis deployment via the Redis service, exposing 9121 on the Redis service, and changing the CLA for the the prometheus-to-sd container such that:

- --source=:http://localhost:9121 -> - --source=:http://my-redis-service:9121

and then using the HPA

1. How did spring instantiate all the necessary variable for CollectorRegistry and setup all the necessary cofnfiguration?

In the first example you require a Bean of type CollectorRegistry and Spring will actually create such bean for you if you have spring-boot-starter-actuator and Prometheus dependencies on your classpath and you have autoconfiguration enabled :

• if you use @EnableAutoConfiguration
• if you are using Spring Boot and @SpringBootApplication annotation (@EnableAutoConfiguration is part of this annotation underneath) :

AFAIK You need to call your function in main()

{"status":"UP"}

Prometheus requires data to be in its format, and cannot handle other arbitrary data. The error you are getting is a parse error due to this.

You should instrument your code using a client library, and have it expose data in the Prometheus text format.
