Yes, if you run supervisor and need automated process monitoring beyond its native capabilities.

Before you install
- Requires supervisor to be installed and running; superlance is a plugin system for supervisor, not a standalone tool.
- Low install friction with a single runtime dependency on supervisor.
- Maintenance is aging—last release was 2021-12-27 with no commits since 2025-10-27, though the repository remains active and unarchived.

What it is and what it does
Superlance is a collection of monitoring plugins designed to extend supervisor, the process control system. It runs as event listeners within supervisor's daemon and responds to process state changes by performing checks—HTTP endpoint health verification, memory usage thresholds, crash detection—and triggering actions like process restarts, email notifications, or SMS alerts.
The package is intended for system administrators running supervisor-based deployments who need automated monitoring beyond supervisor's built-in capabilities. It works by subscribing to supervisor's event system and executing checks on a schedule or in response to process state transitions. Configuration is done through supervisor's own configuration file, making it a natural extension for existing supervisor setups.
Use it for
- Monitor HTTP endpoints of supervised processes and restart them if they stop responding.
- Track memory usage of long-running processes and restart them when they exceed a threshold.
- Detect process crashes and send email or SMS notifications to administrators.
- Batch email alerts for multiple process failures to reduce notification noise.
- Identify processes that restart too frequently and alert only when uptime falls below a threshold.

More System packages
Provides a platform-independent file locking mechanism to coordinate access to files across processes and threads.
Distro provides a reliable, machine-readable API to query the Linux or BSD distribution name, version, codename, and other OS platform details, replacing Python's deprecated `platform.linux_distribution` function.
Install it if you need to detect or report the Linux/BSD distribution your code runs on.
psutil retrieves real-time information about running processes and system resources (CPU, memory, disks, network, sensors) across multiple operating systems, enabling system monitoring, process profiling, and resource management.
Pexpect spawns and controls interactive console applications by sending input and matching output patterns, automating tasks that would otherwise require manual interaction.
Provides asynchronous file I/O operations for asyncio programs, with automatic selection of the best available backend (io_uring, libaio, thread-based, or pure Python) depending on your system.
Portalocker provides cross-platform file locking with support for exclusive and shared locks, plus Redis-based distributed locks and process-aware PID file locking.
Install it if you need file or process coordination; the optional extras (pywin32, redis) are only required for specific lock types.
