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
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

To connect to MongoDB using Navicat, you need to: Install Navicat Create a MongoDB connection: a. Enter the connection name, host address and port b. Enter the authentication information (if required) Add an SSL certificate (if required) Verify the connection Save the connection

.NET 4.0 is used to create a variety of applications and it provides application developers with rich features including: object-oriented programming, flexibility, powerful architecture, cloud computing integration, performance optimization, extensive libraries, security, Scalability, data access, and mobile development support.

In a serverless architecture, Java functions can be integrated with the database to access and manipulate data in the database. Key steps include: creating Java functions, configuring environment variables, deploying functions, and testing functions. By following these steps, developers can build complex applications that seamlessly access data stored in databases.

This article introduces how to configure MongoDB on Debian system to achieve automatic expansion. The main steps include setting up the MongoDB replica set and disk space monitoring. 1. MongoDB installation First, make sure that MongoDB is installed on the Debian system. Install using the following command: sudoaptupdatesudoaptinstall-ymongodb-org 2. Configuring MongoDB replica set MongoDB replica set ensures high availability and data redundancy, which is the basis for achieving automatic capacity expansion. Start MongoDB service: sudosystemctlstartmongodsudosys

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

It is impossible to view MongoDB password directly through Navicat because it is stored as hash values. How to retrieve lost passwords: 1. Reset passwords; 2. Check configuration files (may contain hash values); 3. Check codes (may hardcode passwords).

Detailed explanation of MongoDB efficient backup strategy under CentOS system This article will introduce in detail the various strategies for implementing MongoDB backup on CentOS system to ensure data security and business continuity. We will cover manual backups, timed backups, automated script backups, and backup methods in Docker container environments, and provide best practices for backup file management. Manual backup: Use the mongodump command to perform manual full backup, for example: mongodump-hlocalhost:27017-u username-p password-d database name-o/backup directory This command will export the data and metadata of the specified database to the specified backup directory.
