Returns the list of configured remote SSH hosts. Useful to see what remote machines are available to target.

Fetch CPU load average, RAM, and disk utilization metrics on a single host ('host') or multiple hosts concurrently ('hosts'). If using 'hosts', returns a JSON map mapping hostnames to their metrics. Prefer 'hosts' to query cluster status in parallel.

Lists active listening TCP/UDP ports, matching processes, and PIDs on a single host ('host') or multiple hosts concurrently ('hosts'). If using 'hosts', returns a JSON map mapping hostnames to their active port list. Optionally filter by 'port'. Prefer 'hosts' to scan service availability across multiple machines simultaneously.

Executes a shell command on a single host ('host') or multiple hosts concurrently ('hosts'). If using 'hosts', returns a JSON map mapping hostnames to their stdout, stderr, and exit codes. Features optional 'background' execution (starting the command and returning a local log file path immediately for async tracking), 'quiet' execution (suppressing progress logs), and output abbreviation controls. Prefer 'hosts' to execute commands across cluster nodes simultaneously.

Searches running processes on a single host ('host') or multiple hosts concurrently ('hosts') matching a regex 'pattern'. If using 'hosts', returns a JSON map mapping hostnames to their matched process list. Optionally returns full user/CPU/mem stats if 'full_info' is true. Prefer 'hosts' to find running services across multiple cluster nodes simultaneously.

Fetch the last N lines of a remote log file on a single host ('host') or multiple hosts concurrently ('hosts'). If using 'hosts', returns a JSON map mapping hostnames to their log output. Prefer 'hosts' to query logs across multiple machines simultaneously.

Fetch the last N lines of logs from a remote Docker container on a single host ('host') or multiple hosts concurrently ('hosts'). If using 'hosts', returns a JSON map mapping hostnames to their success status and container log output. Prefer 'hosts' to query container logs across multiple machines simultaneously.

Blocks and streams a remote log file or Docker container logs on a single host ('host') or multiple hosts concurrently ('hosts') until a regex 'pattern' is matched or a timeout is reached. If using 'hosts', returns a JSON map of hostnames to success/error/timeout statuses containing the matched line. Extremely useful for verifying startup or events across cluster nodes without polling.
