mongo 集群监控工具 mongo-monitor 安装部署

调试mongodb 集群期间发现一个小神器,不敢独享!相关介绍如下:
mongo-monitor CLI是一个简洁和简单的工具来检查MongoDB的服务,在集群调试升级期间,故障排查,添加节点,调整分片、修改配置等操作时可以实时查看整个集群状态,全方位了解集群状态,自动秒级刷新状态。

       PRIMARY : 172.19.9.12:27001  
     SECONDARY : 172.19.9.13:27001  

  Shard: shard2

     SECONDARY : 172.19.9.11:27002

  Shard: shard3

       PRIMARY : 172.19.9.11:27003
     SECONDARY : 172.19.9.12:27003
       STARTUP : 172.19.9.13:27003

Time          : 2018-12-04T05:22:48.687Z
Connection    : mongodb://127.0.0.1:27017
Configuration : sharded

安装 mongo-monitor CLI

使用npm 安装

yum install npm -y

npm install -g mongo-monitor        

mac 安装


brew install npm

npm install -g mongo-monitor 

常规使用

连接本地mongo

mongo-monitor mongodb://127.0.0.1:27017     

单独查本地集群某一个分片状态

mongo-monitor 127.0.0.1:27001,127.0.0.1:27002,127.0.0.1:27003?replicaSet=shard3     

查看远程mongodb 集群 shard 2 分片状态;

mongo-monitor 10.12.7.194:27002,10.12.7.165:27002,10.12.7.78:27002?replicaSet=shard2        
Time          : 2018-12-04T05:43:28.414Z
Connection    : mongodb://10.12.7.194:27002,10.12.7.165:27002,10.12.7.78:27002?replicaSet=shard2
Configuration : replicaset

  Replicaset: shard2

     SECONDARY : 10.12.7.165:27002
       PRIMARY : 10.12.7.194:27002
     SECONDARY : 10.12.7.78:27002

Events:
    2018-12-04T05:43:26.366Z : joined
    2018-12-04T05:43:26.364Z : joined

验证方式登录

mongo-monitor admin:P@[email protected]:27002,10.12.7.165:27002,10.12.7.78:27002?replicaSet=shard2

如果输入连接端口和shard不匹配,将打印告警信息如下:

Events:
    2018-12-04T05:42:46.306Z : setName from ismaster does not match provided connection setName [shard2] != [shard1]
    2018-12-04T05:42:45.291Z : setName from ismaster does not match provided connection setName [shard2] != [shard1]

连接远程待认证集群节点

mongo-monitor 192.168.1.5:27001,127.0.0.1:27002,127.0.0.1:27003?replicaSet=shard3

问题

调试期间发现这个工具打印的信息略少,给开发者提了一个 issues ,希望能多输出点信息,加上分片使用内存,网络等信息:
