watchdogd

watchdogd is a command line tool available on Unix-like systems and macOS. It is responsible for monitoring and managing system processes. The primary purpose of watchdogd is to ensure that critical system processes and applications are running smoothly. It constantly checks if the processes are responding correctly and restarts them if needed.

watchdogd acts as a watchdog or guardian for system process management, making it an essential tool in maintaining system uptime and stability. It monitors processes for any failures, crashes, or unresponsiveness, and automatically takes action to restart or relaunch them.

This command line tool utilizes various mechanisms, such as polling and signaling, to keep track of process states and respond accordingly. It can also be configured to monitor specific processes based on defined rules or criteria.

In addition to its monitoring capabilities, watchdogd can generate logs and notifications in case of process failures, allowing administrators to troubleshoot and resolve issues promptly. It provides system administrators with a reliable way to keep critical processes running and minimize system downtime.
