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
| Command | Description |
|---|---|
cpu scan <input> | Record a scan result (or view recent scans with no args) |
cpu monitor <input> | Log a monitoring observation (or view recent monitors) |
cpu report <input> | Record a report entry (or view recent reports) |
cpu alert <input> | Log an alert event (or view recent alerts) |
cpu top <input> | Record a top-process snapshot (or view recent tops) |
cpu usage <input> | Log a usage measurement (or view recent usage records) |
cpu check <input> | Record a health check (or view recent checks) |
cpu fix <input> | Log a fix or remediation (or view recent fixes) |
cpu cleanup <input> | Record a cleanup action (or view recent cleanups) |
cpu backup <input> | Log a backup event (or view recent backups) |
cpu restore <input> | Record a restore operation (or view recent restores) |
cpu log <input> | Add a general log entry (or view recent log entries) |
cpu benchmark <input> | Record a benchmark result (or view recent benchmarks) |
cpu compare <input> | Log a comparison (or view recent comparisons) |
cpu stats | Show summary statistics across all log files |
cpu search <term> | Search all entries for a keyword (case-insensitive) |
cpu recent | Show the 20 most recent activity entries |
cpu status | Health check — version, entry count, disk usage, last activity |
cpu help | Display all available commands |
cpu version | Print version string |
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>.logand logs tohistory.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/:
| File | Contents |
|---|---|
scan.log | System scan results |
monitor.log | Monitoring observations |
report.log | Report entries |
alert.log | Alert events |
top.log | Top-process snapshots |
usage.log | Usage measurements |
check.log | Health check records |
fix.log | Fix/remediation records |
cleanup.log | Cleanup action records |
backup.log | Backup event records |
restore.log | Restore operation records |
log.log | General log entries |
benchmark.log | Benchmark results |
compare.log | Comparison records |
history.log | Unified activity log for all commands |
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
- Tracking system operations — use
scan,monitor,check, andalertto maintain a timestamped journal of system health events and observations - Recording fixes and remediations — use
fixandcleanupto document what was changed and when, creating an audit trail for incident response - Benchmarking and comparing performance — use
benchmarkandcompareto log performance results over time and track improvements or regressions - Managing backup and restore history — use
backupandrestoreto log when backups were taken and restores were performed, with searchable history - Searching operational history — use
search <term>to find specific events across all log categories, orrecentto 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
