关于prometheus:prometheusalertmanagergrafanadingtalk告警搭建

46次阅读

共计 21604 个字符，预计需要花费 55 分钟才能阅读完成。

阐明：prometheus、alertmanager、grafana、dingtalk、node_exporter 均应用 k8s 部署
k8s 版本：v1.20.15
所有利用部署形式：docker 启动，且都能失常应用

一、yaml 筹备

二、部署

阐明：prometheus 的 configmap 外面配置了除 k8s 集群之外的监控（mysql、redis 等等），dingtalk 的 configmap 外面配置 webhook url 也须要改成本人的，在这里咱们先能够将 prometheus、alertmanager、grafana、dingtalk、node_exporter 先部署起来，前面再依据本人的需要进行配置。
这里咱们将所有的 yaml 放在同一目录上面。

# 先创立一个名字为 prom-test 的 namespace, 也可间接改为本人的
[root@master /home/yaml/prometheus-all]# kubectl create ns prom-test
 
# 执行部署
[root@master /home/yaml/prometheus-all]# kubectl apply -f .
......
 
# 查看该名称空间下的 pod, 保障 pod 状态都是为 Running 就 ok 了
[root@master /home/yaml/prometheus-all]# kubectl get po -n prom-test 
NAME                            READY   STATUS    RESTARTS   AGE

node-exporter-bpm95             1/1     Running   0          9d

prometheus-56744b95c7-p8kjx     1/1     Running   0          2d4h
 
# 查看该名称空间下的 service
[root@master /home/yaml/prometheus-all]# kubectl get svc -n prom-test 
NAME           TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
alertmanager   NodePort    10.99.144.191    <none>        9093:30333/TCP   2d4h
dingtalk       ClusterIP   10.101.207.48    <none>        8060/TCP         2d4h
grafana        NodePort    10.102.61.131    <none>        3000:31430/TCP   8d
prometheus     NodePort    10.103.228.196   <none>        9090:30650/TCP   2d4h
 
# 除了 dingtalk 之外，TYPE 不是 nodeport 的咱们能够应用以下命令批改
kubectl patch svc grafana -n prom-test -p '{"spec": {"type":"NodePort"}}'

dashboard 的拜访形式均为：{k8s-master ip} : {port}
