Server Pulse

Server Pulse solves the critical problem of fragmented system administration. System administrators and DevOps teams managing complex infrastructure face multiple challenges:

• Multiple tools required for different tasks - jump between Docker CLI, firewall tools, log viewers, and monitoring dashboards
• Limited accessibility in headless/SSH-only environments where graphical tools are unavailable
• Lack of integrated security oversight - firewall status, intrusion detection, SSL certificates, password policies scattered across different tools
• Difficulty tracking system health holistically - CPU, memory, I/O, network metrics not unified
• Complex container management without system context
• Time-consuming log analysis across multiple sources (journald, syslog, files)

Server Pulse unifies all these functions into a single, cohesive terminal interface with real-time monitoring, built using Go, BubbleTea for TUI framework, and integrated system APIs.

• Integrating multiple complex system subsystems (firewall, intrusion detection, SSL, logs, network, Docker) into a unified interface.
• Real-time performance monitoring while parsing system APIs.
• Building responsive TUI with proper state management across multiple tabs and data sources.
• Handling privilege escalation (sudo) for privileged operations.
• Supporting multiple firewall types (UFW, firewalld, iptables, nftables) and intrusion prevention services (fail2ban, crowdsec, OSSEC, Suricata, etc).
• Parsing logs from multiple sources (journald, syslog, files) with filtering capabilities.
• Managing Docker API connections while also monitoring host system metrics.
• Implementing interactive shell sessions without disrupting TUI state.
• Terminal resize handling with complex multi-panel layouts.

Architected modular system with separated concerns:

• Performance module (CPU, Memory, I/O, System Health via gopsutil)

• Security module (Firewall detection and status, Intrusion prevention service detection, SSL certificate validation)

• Network module (Connectivity via ping/traceroute, Routes IPv4/IPv6, Connections, DNS)

• Logs module (Journald/Syslog/File detection with multi-level filtering)

• Docker integration (Moby client for container management)

• and Processes module.

• Used BubbleTea framework for event-driven TUI architecture with panic recovery and proper terminal handling.

• Implemented Lipgloss for consistent styling across 8+ security and monitoring subsystems.

• Utilized system command parsing for firewall and intrusion detection status.

• Integrated gopsutil for cross-platform system metrics.

• Built CLI command execution with sudo support for privileged operations.

• Implemented real-time ASCII graphs via asciigraph for performance visualization.

• Created interactive shell session management with proper terminal restoration.

• System Performance Monitoring (CPU, Memory, I/O, Load Average)
• System Health Metrics (IOWait, StealTime, Context Switches, Page Faults)
• Firewall Management & Status (UFW, firewalld, iptables, nftables)
• Intrusion Prevention Service Detection (fail2ban, crowdsec, OSSEC, Suricata, Snort, DenyHosts, SSHGuard)
• SSL/TLS Certificate Validation & Expiry Monitoring
• SSH Security Configuration Management
• Password Policy Enforcement
• System Updates Tracking (apt, yum, dnf)
• System Restart Management
• Multi-source Log Aggregation (Journald, Syslog, File-based)

• Network Connectivity Diagnostics (Ping, Traceroute)
• Route Management (IPv4 & IPv6)
• Network Connection Monitoring
• DNS Configuration Viewing
• Docker Container Lifecycle Management (Start, Stop, Restart, Delete)
• Docker Container Performance Monitoring (CPU, Memory, I/O, Network)

• Docker Container Details (Environment, Ports, Health Status, Mounts)
• Docker Compose Project Integration
• Process Monitoring & Management
• Interactive Shell Access within Containers
• Performance Reports & Export
• Responsive Terminal UI with Mouse Support
• Docker Permission Validation
