Process Resource Monitor (PRM)

Monitor and enforce process resource limits

Overview

Process Resource Monitor (PRM) is a CPU, memory, process count, and run time resource monitor for Linux and BSD systems.

PRM supports both global-scoped limits and granular rule-based limits on a per-process or per-user basis. When resource thresholds are exceeded, PRM can terminate offending processes with optional parent/child tree termination and trigger service restarts post-termination to maintain availability.

Features

Monitoring

• CPU, memory, process count, and run time resource monitoring
• Global scoped or rule-based per-process and per-user limits
• Per-user and per-command rule files for granular control
• Soft rechecks before termination to reduce false positives

Response

• Parent/child tree termination for complete process cleanup
• Service restart post-termination to maintain availability
• Root process exemption to prevent critical service disruption
• Rules-only mode and alert-only mode for flexible operation
• Regex-based ignore options for process exclusion
