K8S Prometheus-rocketmq-exporter配置

下载rocketmq-exporter

通过Docker仓库下载

docker pull sawyerlan/rocketmq-exporter:latest

然后打标签，推送到自己的仓库

也可通过代码自己build镜像

git clone GitHub - apache/rocketmq-exporter: Apache RocketMQ Prometheus Exporter

然后打标签，推送到自己的仓库

准备configMap

部署export前需要有一个可用的rocketmq环境，需要提前将rocketmq的namesrvAddr准备好

将namesrvAddr存入configMap中

 vi rocketmq-standalone-exporter-cm.yamlapiVersion: v1
kind: ConfigMap
metadata:name: rocketmq-standalone-exporter-cmnamespace: develop
data:namesrvAddr: "--rocketmq.config.namesrvAddr=你的nameserver:9876"

创建configMap

kubectl apply -f rocketmq-standalone-exporter-cm.yaml

部署exporter

编写service和pod部署文件，使用上面configMap中的namesrvAddr

vi deployment.yamlapiVersion: v1
kind: Service
metadata:name: rocketmq-standalone-exporter-svclabels:app: rocketmq-standalone-exporter-svcapp.kubernetes.io/component: metricsapp.kubernetes.io/instance: rocketmq-standalone-exporternamespace: develop

开始部署 kubectl apply -f deployment.yaml

检查 pod的log日志是否有异常

curl 查看你的svc:5557/metric能否获取指标数据

创建ServiceMonitor

定时将指标数据存入到prometheus中

vi serviceMonitor-rocketmq-standalone.yamlapiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:labels:jobLabel: rocketmq-standalone-exportername: prometheus-prometheus-rocket-standalone-exporternamespace: develop
