• Alerting: Configure alerts to notify you when critical thresholds are exceeded, allowing you to proactively address potential issues before they escalate.
• Log Management: Centralize your server logs using tools like ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk to facilitate log analysis and troubleshooting. Centralized log management allows you to quickly identify and diagnose issues by searching and analyzing logs from multiple servers in one place.

3. Modernize Server Management

The search results highlight the importance of modernizing server management practices. This may involve migrating away from traditional on-premises solutions to more modern, cloud-based, or hybrid approaches.

• Cloud Server Management: Explore the benefits of cloud computing platforms like AWS, Azure, or Google Cloud. Cloud platforms offer a wide range of server management tools and services, such as automated scaling, patching, and monitoring.
