Get comprehensive system status for production server monitoring. Covers performance metrics, hardware specs, software environment, storage & disk I/O, network traffic & connections, running processes, systemd services, Docker containers, CPU/GPU temperatures, logged-in users, security posture (open ports), displays, battery, and peripherals. Use 'overview' for a quick health snapshot, or specify a category for deep details.

Scan the system for known service configuration files (nginx, mysql, redis, docker, sshd, etc.), or scan a specific directory for project-level config files (like .env, .npmrc, *.json). Returns a list of detected config files with their paths, sizes, and last modified times.

Read and parse a specific service configuration file. Supports JSON, YAML, INI, TOML, env, nginx conf, sshd_config, sysctl, crontab, hosts, fstab, resolv.conf, and more. You can specify either a service name (e.g. 'nginx') to auto-locate the config, or provide a direct file path for custom configs.

Safely read the end of a log file (tail), optionally filtering by a keyword (grep). Extremely efficient for huge log files as it reads backwards from the end without loading the whole file into memory. Use this instead of read_config for files like /var/log/syslog, nginx access logs, or any file that could be massive.
