Server monitoring is important for a number of reasons:
To ensure uptime: By monitoring your servers, you can ensure that they are running smoothly and that downtime is kept to a minimum. This helps to ensure that your customers can access your services without interruption.
To improve performance: Monitoring server performance can help you identify bottlenecks and areas where resources are being over-utilized. By identifying these areas, you can optimize your servers for better performance and reduce the risk of slowdowns or crashes.
To detect security threats: Server monitoring can help you detect potential security threats, such as unauthorized access attempts, malware infections, or DDoS attacks. By identifying these threats early, you can take action to prevent them from causing damage to your systems.
To track resource usage: Monitoring server resource usage can help you identify trends and patterns in how your servers are being used. This can help you plan for future capacity needs and ensure that you are using your resources efficiently.
