If the average percentage of successful checks within the last minute is below 75%, it triggers an alert indicating the TCP service is not functioning properly. - -### Troubleshoot the alert - -- Verify if the problem is network-related or service-related - - 1. Check if the host and port are correct and the service is configured to listen on that specific port. - - 2. Use `ping` or `traceroute` to diagnose the connectivity issues between your machine and the host. - - 3. Use `telnet` or `nc` to check if the specific port on the host is reachable. For example, `telnet example.com port_number` or `nc example.com port_number`. - - 4. Check the network configuration, firewall settings, and routing rules on both the local machine and the target host. - -- Check if the TCP service is running and functioning properly - - 1. Check the service logs for any errors or issues that may prevent it from working correctly. - - 2. Restart the service and monitor its behavior. - - 3. Investigate if there are any recent changes in the service configuration or updates that may cause the issue. - - 4. Monitor system resources such as CPU, memory, and disk usage to ensure they are not causing any performance bottlenecks. - -- Optimize the service configuration - - 1. Review the service's performance-related configurations and fine-tune them, if necessary. - - 2. Check if there are any optimizations or best practices that can be applied to boost the service performance and reliability. - |
