Features

• Background Process Managers - Provides a comprehensive system for running applications as daemons with automatic restarts and lifecycle management.
• Process Supervisors - Starts and monitors multiple background programs with automatic restarts and lifecycle management.
• Background Daemon Managers - Ensures continuous execution as a background daemon independently of the user session on Unix and Windows.
• REST Management APIs - Implements a REST management API for controlling daemon lifecycles and retrieving system status programmatically.
• Health Checks - Implements runtime health monitoring via TCP and HTTP probes to ensure background services remain operational.
• Management API Exposures - Provides a network interface to remotely administer and control background processes via HTTP requests.
• Process Readiness Probes - Verifies process readiness by scanning for specific strings in output streams or executing validation scripts.
• Polling-Based Health Monitors - Periodically validates process readiness by monitoring TCP connections, HTTP response codes, or specific output strings.
• Remote Administration Interfaces - Offers remote administration interfaces including a REST API and XML-RPC controller for managing background services.
• Remote Process Management - Allows the use of network requests over sockets to manage and monitor active processes from external machines.
• Remote Server Management Tools - Exposes a management server with authentication to control system operations from a remote location.
• Process State Monitors - Tracks and reports the operational status and process IDs of managed programs to ensure they run as expected.
• Process Stream Redirection - Captures standard output and error streams from child processes into files with configurable rotation and size limits.
• CLI Process Controllers - Provides a command-line utility to trigger status checks and reload the runtime state of supervised processes.
• Process Runtime Environment Configurations - Assigns environment variables and sets working directories to define the full execution context for spawned processes.
• Process Event Triggers - Triggers specific actions based on process state changes, communication events, and timed intervals.
• Environment Variable Configurations - Imports key-value pairs from external environment files to inject runtime settings into managed processes.
• Startup and Shutdown Sequencing - Coordinates the specific order of process startup and shutdown using priority-based group scheduling.
• File-Change-Triggered Restarts - Restarts processes automatically when executable binaries or monitored files are updated.
• REST API Interfaces - Implements server-side RESTful endpoints for starting, stopping, and monitoring the status of running programs.
• XML-RPC Servers - Hosts an XML-RPC server to process remote procedure calls for controlling processes via TCP or Unix sockets.
• Zombie Process Reclamation - Automatically reclaims system resources from terminated child processes to prevent zombie processes and resource exhaustion.
• Process Grouping and Prioritization - Organizes processes into logical groups with priority settings to coordinate the sequence of startup and shutdown.
• Process Group Signaling - Organizes multiple programs into groups for collective starting, stopping, and signaling of related processes.
• Process Lifecycle State Machines - Uses a state machine to trigger automated actions based on process operational status changes and system ticks.
• Service State Controls - Provides administrative endpoints to manage the supervisor's operational state, including configuration reloading and service shutdown.
• Web-Based Management Interfaces - Ships a built-in web interface to start, stop, and check the status of supervised programs.
• Execution Log Redirection - Routes standard output and error streams from supervised processes to files, local syslog, or remote syslog servers.
• Health Metrics Exposure - Exposes internal system health and process performance metrics for external monitoring tools via HTTP.
• Log Rotation Utilities - Includes utilities for managing disk space by automatically rotating and archiving process log files based on size.
• Prometheus-Formatted HTTP Endpoints - Serves a Prometheus-formatted HTTP endpoint for external scraping of process and system metrics.
• Process Log Captures - Captures process stdout and stderr into files with configurable rotation and backup counts.
• Process State Event Listeners - Provides programs that trigger automated actions based on changes in the state of managed processes.
• Prometheus Metrics Exporters - Exposes real-time system and process metrics in Prometheus format via a dedicated HTTP endpoint.
• Prometheus System Metrics Exporters - Exports CPU, memory, and process metrics in Prometheus format through a dedicated REST endpoint.
• Monitoring and Alerting - Process manager implementation.
