Linux: checks before making changes
When diagnosing a Linux server, separate system, storage, service and network symptoms. Understand the effect of a command before applying it in production.
Method and good practice
- Review logs and service status; on systems using systemd, journalctl and systemctl are useful starting points.
- Check disk space and inodes, then memory use and system load before considering a restart.
- For a network incident, check addresses, routes, DNS resolvers and listening sockets.
