如何在java程序中收集Prometheus度量

Question

我搜索了大部分文章，但没有找到我期望的解决方案。我是普罗米修斯的新手。我需要通过我的java程序收集Prometheus度量。因此，需要帮助通过我的java程序读取或获取Prometheus度量。

任何帮助或建议都会有帮助。

感谢

Answer 1

如果使用Spring boot 2.1.5.RELEASE，则

1. 添加相关性执行器和测微计普罗米修斯
   

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency> 
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

2. 添加配置以启用对端点/执行器/普罗米修斯的访问

management:
endpoints:
web:
exposure:
include: '*'

3. 尝试请求http://domain:port/actuator/prometheus

编辑对于kubernetes im使用种类部署：

apiVersion: apps/v1
kind: Deployment
metadata:
name: myAppName
spec:
replicas: 1
selector:
matchLabels:
app: myAppName
template:
metadata:
labels:
app: myAppName
annotations:
prometheus.io/scrape: "true"
prometheus.io/port: "8091"
prometheus.io/path: "/actuator/prometheus"
spec:
containers:
- name: myAppName
image: images.com/app-service:master
imagePullPolicy: Always
ports:
- containerPort: 8091
env:
- name: INSTANCE_IP
valueFrom:
fieldRef:
fieldPath: status.podIP
- name: SPRING_PROFILES_ACTIVE
value: "prod"
- name: CONFIG_SERVER_ADDRESS
value: "http://config-server:8888"
livenessProbe:
failureThreshold: 3
httpGet:
path: /actuator/health
port: 8091
scheme: HTTP
initialDelaySeconds: 45
periodSeconds: 10
successThreshold: 1
timeoutSeconds: 5
readinessProbe:
failureThreshold: 5
httpGet:
path: /actuator/health
port: 8091
scheme: HTTP
initialDelaySeconds: 30
periodSeconds: 10
successThreshold: 1
timeoutSeconds: 5
nodeSelector:
servicetype: mvp-cluster
