Seer

A comprehensive CLI system monitoring tool built in Rust that provides real-time system information in a terminal user interface.

Features

• Real-time System Monitoring: CPU, memory, disk, and network usage
• Process Management: View running processes with sorting and filtering capabilities
• Process Tree View: Hierarchical display of process relationships
• Historical Data Tracking: Track system metrics over time with 24-hour history
• Interactive TUI: Built with Ratatui for a responsive terminal interface
• Data Export: Export current metrics and historical data to JSON, CSV, or TOML formats
• Multiple Views: Dashboard, Process List, Process Tree, Network, Disk, System Info, and History
• Customizable Thresholds: Set CPU and memory usage alerts
• Zombie Process Detection: Highlight and filter zombie processes
• Network Monitoring: Interface statistics and listening ports display
• Search Functionality: Search and filter processes by name
• Enhanced Process Management:
  • Process grouping by user, parent process, application, or status
  • CPU affinity viewing and management (Linux)
  • Resource limits monitoring and display
  • Process performance profiling with anomaly detection
• Security & Monitoring Enhancements:
  • Security Dashboard: Real-time security threat monitoring and suspicious process detection
  • Log Monitoring: System log analysis with security pattern detection and alerts
  • Filesystem Monitoring: Critical file and directory integrity monitoring with change detection
  • Behavioral Analysis: Process behavior profiling and anomaly detection
  • Privilege Escalation Detection: Monitor and alert on unauthorized privilege changes
• Multiple Themes: 5 built-in color themes (Default, Dark, Gruvbox, Dracula, Solarized)
• Keyboard Navigation: Intuitive controls for navigating data

Installation

Prerequisites

• Rust 1.70 or later
• Cargo package manager

Build from Source

git clone <repository-url>
cd seer
cargo build --release

The binary will be available at target/release/seer.

Usage

Basic Usage

seer

Command Line Options

• -r, --refresh-rate <SECONDS>: Set refresh rate (default: 2 seconds)
• --show-zombies: Show zombie processes
• -f, --filter-process <NAME>: Filter processes by name
• -e, --export <FORMAT>: Export data to specified format (json, csv, toml)
• --threshold-cpu <PERCENTAGE>: CPU usage threshold (default: 80%)
• --threshold-memory <PERCENTAGE>: Memory usage threshold (default: 80%)

Examples

# Set refresh rate to 1 second
seer -r 1

# Show zombie processes with CPU threshold of 90%
seer --show-zombies --threshold-cpu 90

# Filter processes containing "rust"
seer -f rust

# Export system data
seer -e json

Configuration

Seer supports configuration through a TOML file located at ~/.config/seer/config.toml. The configuration file allows you to set default values for various options.

Example configuration:

refresh_rate = 2
show_zombies = false
threshold_cpu = 80.0
threshold_memory = 80.0

Enhanced Process Management Features

Process Grouping

View and analyze processes organized by:

• User: Group processes by the user running them
• Parent Process: Group processes by their parent PID
• Application: Group processes by application/executable name
• Status: Group processes by their current status (Running, Sleeping, etc.)

CPU Affinity Management (Linux)

• View current CPU affinity settings for processes
• Modify CPU affinity using taskset integration
• Display CPU topology information
• Manage which CPU cores processes can run on

Resource Limits Monitoring

• Display process resource limits (ulimits)
• Monitor resource usage against limits
• Show warnings when processes approach limits
• Track memory, file descriptors, CPU time, and other resources

Performance Profiling

• Real-time performance tracking for all processes
• CPU and memory usage trend analysis
• Anomaly detection (CPU spikes, memory leaks)
• Process efficiency scoring
• Historical performance data with statistics

Dependencies

• sysinfo: System information gathering
• ratatui: Terminal user interface framework
• crossterm: Cross-platform terminal manipulation
• tokio: Async runtime
• clap: Command line argument parsing
• chrono: Date and time handling
• serde: Serialization framework
• serde_json: JSON serialization
• csv: CSV file handling
• toml: TOML configuration format
• num_cpus: CPU topology detection

Platform Support

• Linux: Full feature support including CPU affinity management and resource limits
• macOS/Windows: Core monitoring features supported, some advanced features may be limited

Linux-Specific Features

• CPU affinity viewing and modification (requires taskset utility)
• Resource limits monitoring via /proc filesystem
• Enhanced process information from /proc/pid/ files
