3. Common Maintenance Tasks

Here’s how to automate some common tasks:

3.1. Backup Automation

Use `mongodump` for automated backups:

#!/bin/bash
            TIMESTAMP=$(date +"%F")
            BACKUP_DIR="/path/to/backup/$TIMESTAMP"
            mkdir -p "$BACKUP_DIR"
            mongodump --out "$BACKUP_DIR"

Schedule the script using crontab:

0 2 * * * /path/to/backup_script.sh

3.2. Monitoring Performance

Automate performance monitoring using a script that checks for slow queries:

db.getProfilingStatus();
            db.system.profile.find({ millis: { $gt: 100 } }).sort({ millis: -1 });

4. Automation Tools

Consider using:

• MongoDB Ops Manager for comprehensive management.
• Custom scripts for tailored solutions.
• Third-party tools like ClusterControl or Studio 3T.

5. Best Practices

• Document all automated processes.
• Use version control for scripts.
• Regularly review and update automation scripts.
• Monitor the results of automated tasks frequently.
