Eureka Service Discovery

[Marco Schmucki]

Hi all

I've implemented the eureka_sd_configs:

# my global config

global:

  scrape_interval:     60s # Default is every 1 minute.

  evaluation_interval: 60s # The default is every 1 minute.

# Alertmanager configuration

alerting:

  alertmanagers:

  - static_configs:

    - targets:

      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.

rule_files:

  # - "first_rules.yml"

  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:

# Here it's Prometheus itself.

scrape_configs:

  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.

  - job_name: 'prometheus'

    static_configs:

    - targets: ['localhost:9090']

  # eureka service discovery

  - job_name: 'eureka'

    metrics_path: '/actuator/prometheus'

    eureka_sd_configs:

      - server: http://eureka.example.com:8761/eureka

The services  are shown under the register "target".

But one service is not correct, because this service takes the default "__meta_eureka_app_instance_port", but it should take the "__meta_eureka_app_instance_metadata_management_port".

I already tried to change it with the following without success (https://github.com/prometheus/prometheus/blob/release-2.22/documentation/examples/prometheus-eureka.yml):

1. prometheus config:

- source_labels: [__address__, __meta_eureka_app_instance_metadata_prometheus_port]
  action: replace
  regex: ([^:]+)(?::\d+)?;(\d+)
  replacement: $1:$2

  target_label: __address__


2. service application properties:

eureka.instance.metadataMap[prometheus.port]=9091  

How can I change the port of one of the services?

Many thanks for your feedback.

Regards,

Marco

I was able to get it worked.

I've changed the following:

--> OLD not working (with FQDN):

eureka_sd_configs:

      - server: http://eureka.example.com:8761/eureka

--> NEW is working (with docker-container-name):

eureka_sd_configs:

      - server: http://eureka-node1:8761/eureka
