在有些情况下,只能使用远程的MongoDB实例而不能登录到MongoDB实例所在的服务器上,这时可以在一台服务器上维护一个远程MongoDB实例的主机和端口列表,,然后通过zabbix的低级发现功能去根据主机和端口自动添加相应的监控。


  • MongoDB主机和端口发现脚步mongodb_discovery.py

    主机和端口列表文件mongodb_servers.txt,文件中存放每个实例的主机,端口信息


  • 10.4.9.112:28018:root:xxxx 10.4.9.2:27017:root 10.4.9.3:28018#/usr/bin/python #This script is used to discovery disk on the server import subprocess import json args='''awk -F':' '{print $1":"$2}' /usr/local/zabbix/bin/mongodb_servers.txt''' t=subprocess.Popen(args,shell=True,stdout=subprocess.PIPE).communicate()[0] mongodbs=[] for mongo in t.split('\n'):     if len(mongo) != 0:        mongodbs.append({'{#MONGO_HOST}':mongo}) print json.dumps({'data':mongodbs},indent=4,separators=(',',':'))


    显示结果:

    {     "data":[         {             "{#MONGO_HOST}":"192.168.5.7:30000"         },         {             "{#MONGO_HOST}":"192.168.5.7:30001"         },         {             "{#MONGO_HOST}":"192.168.5.23:30002"         },         {             "{#MONGO_HOST}":"192.168.5.23:30003"         }     ] }



    2.获取MongoDB端口状态信息脚本discovery_mongodb_status.sh

    这里会根据{#MONGO_HOST}传来的值在mongodb_servers.txt文件中找到相应的行,并以冒号 “:” 判断整行的长度,然后使用不同的mongodb连接方式

     

    #This script is used to get discovered  mongodb servers status #echo "db.serverStatus().uptime"|mongo 192.168.5.23:30002/admin  -uroot -pxxxx #echo "db.serverStatus().mem.mapped"|mongo 192.168.5.23:30002/admin  -uroot -pxxx #echo "db.serverStatus().globalLock.activeClients.total"|mongo 192.168.5.23:30002/admin  -uroot -pxxx # Macro {#MONGO_INFO}  "HOSTNAME:PORT:USERNAME:PASSWORD" #sh discovery_mongodb_status.sh  uptime  {#MONGO_HOST}  #sh discovery_mongodb_status.sh  mem mapped  {#MONGO_HOST}  #sh discovery_mongodb_status.sh  globalLock activeClients total  {#MONGO_HOST}  #one more parameter mongo_info="" command_line="" function check_mongo_info() {     num=$(echo $mongo_info|awk -F":" '{print NF}')     host=$(echo $mongo_info|awk -F":" '{print $1}')     port=$(echo $mongo_info|awk -F":" '{print $2}')     username=$(echo $mongo_info|awk -F":" '{print $3}')     password=$(echo $mongo_info|awk -F":" '{print $4}')         case $num in      2)        command_line="/data/app_platform/mongodb/bin/mongo $host:$port/admin"        ;;      3)        command_line="/data/app_platform/mongodb/bin/mongo $host:$port/admin -u$username -p''"        ;;      4)        command_line="/data/app_platform/mongodb/bin/mongo $host:$port/admin -u$username -p$password"        ;;      esac                                          } case $# in   2)         mongo_info=$(grep $2 /usr/local/zabbix/bin/mongodb_servers.txt)     check_mongo_info      output=$(/bin/echo "db.serverStatus().$1" |$command_line|sed -n '3p')     ;;   3)     mongo_info=$(grep $3 /usr/local/zabbix/bin/mongodb_servers.txt)     check_mongo_info     output=$(/bin/echo "db.serverStatus().$1.$2" |$command_line|sed -n '3p')     ;;   4)     mongo_info=$(grep $4 /usr/local/zabbix/bin/mongodb_servers.txt)     check_mongo_info     output=$(/bin/echo "db.serverStatus().$1.$2.$3" |$command_line|sed -n '3p')     ;; esac #check if the output contains "NumberLong" if [[ "$output" =~ "NumberLong"   ]];then   echo $output|sed -n 's/NumberLong(//p'|sed -n 's/)//p' else    echo $output fi

    How to ensure high availability of MongoDB on Debian How to ensure high availability of MongoDB on Debian Apr 02, 2025 am 07:21 AM

    This article describes how to build a highly available MongoDB database on a Debian system. We will explore multiple ways to ensure data security and services continue to operate. Key strategy: ReplicaSet: ReplicaSet: Use replicasets to achieve data redundancy and automatic failover. When a master node fails, the replica set will automatically elect a new master node to ensure the continuous availability of the service. Data backup and recovery: Regularly use the mongodump command to backup the database and formulate effective recovery strategies to deal with the risk of data loss. Monitoring and Alarms: Deploy monitoring tools (such as Prometheus, Grafana) to monitor the running status of MongoDB in real time, and
