Cpu

Cpu v2.0.0 — a sysops toolkit for scanning, monitoring, reporting, alerting, benchmarking, and managing system operations. Each command logs timestamped records locally, providing a lightweight operations journal for tracking system events, fixes, backups, and performance comparisons.

Commands

Each operations command (scan, monitor, report, alert, top, usage, check, fix, cleanup, backup, restore, log, benchmark, compare) works identically:

• With arguments: saves a timestamped entry to ~/.local/share/cpu/<command>.log and logs to history.log
• Without arguments: displays the 20 most recent entries from that command's log file

Data Storage

All data is stored locally in ~/.local/share/cpu/:

The stats command reads all .log files and reports line counts per file, total entries, data directory size, and the timestamp of the first recorded activity.

The export utility function can produce JSON, CSV, or TXT output files under the data directory.

Requirements

• Bash (4.0+)
• coreutils — date, wc, du, head, tail, grep, basename, cat
• No external dependencies, API keys, or network access required
• Works on Linux and macOS

When to Use

1. Tracking system operations — use scan, monitor, check, and alert to maintain a timestamped journal of system health events and observations
2. Recording fixes and remediations — use fix and cleanup to document what was changed and when, creating an audit trail for incident response
3. Benchmarking and comparing performance — use benchmark and compare to log performance results over time and track improvements or regressions
4. Managing backup and restore history — use backup and restore to log when backups were taken and restores were performed, with searchable history
5. Searching operational history — use search <term> to find specific events across all log categories, or recent to view the latest 20 activities at a glance

Examples

# Record a scan finding
cpu scan "port 8080 open on web-server-01"

# Log a monitoring observation
cpu monitor "memory usage at 78% on db-primary"

# Record an alert
cpu alert "disk /var/log at 92% capacity"

# Log a fix
cpu fix "rotated nginx logs, freed 2.3GB on web-01"

# Record a benchmark result
cpu benchmark "sysbench cpu run: 1847 events/sec"

# Compare two environments
cpu compare "prod latency 45ms vs staging 62ms"

# Log a backup
cpu backup "full backup of postgres completed 14.2GB"

# Search all logs for a keyword
cpu search "disk"

# View summary statistics
cpu stats

# Check system status
cpu status

# View recent activity
cpu recent

How It Works

Cpu uses a simple append-only log architecture. Every command writes a pipe-delimited record (timestamp|value) to its dedicated log file. The history.log file captures a unified timeline of all operations with the format MM-DD HH:MM command: value.

This design makes Cpu:

• Fast — pure bash, no database overhead
• Transparent — all data is human-readable plain text
• Portable — works anywhere bash runs, no install needed
• Auditable — every action is timestamped and traceable
