How do you handle server health checks and fault tolerance in backend systems?

Server health checks and fault tolerance play a vital role in ensuring the smooth operation of backend systems. Here are some key points to address the most frequently asked question:   Server Health Checks:   Regular monitoring of server metrics is crucial to identify any issues promptly. Implementing automated health checks using tools like Nagios or Grafana helps in checking the server’s overall status, availability, and performance.   **Nagios**: Nagios is a popular open-source monitoring tool that can perform various checks, including monitoring CPU, memory, disk usage, network connectivity, and more. It sends alerts or notifications when predefined thresholds are exceeded. **Grafana**: Grafana is another powerful tool that allows you to create customized dashboards to monitor and visualize server metrics. It integrates with various data sources and offers a wide range of visualization options.   Load balancers like NGINX or HAProxy are widely used to distribute incoming traffic across multiple servers. They continuously check the health of backend servers and exclude any unhealthy servers from
