Mesh Network

Name: Nebula
Rating: 5 (4373 reviews)
Author: bytesagain

Sysops toolkit for scanning, monitoring, reporting, alerting, and managing network infrastructure. Mesh Network provides a complete operations workflow — scan nodes, monitor services, generate reports, set alerts, track usage, run benchmarks, manage backups, and compare configurations. All entries are timestamped and stored locally for full traceability.

Commands

Monitoring & Scanning

Command	Description
`mesh-network scan <input>`	Scan network nodes or services. Run without args to view recent scan entries
`mesh-network monitor <input>`	Log monitoring observations. Run without args to view recent monitor entries
`mesh-network top <input>`	Record top resource consumers or metrics. Run without args to view recent top entries
`mesh-network usage <input>`	Track resource usage data. Run without args to view recent usage entries
`mesh-network check <input>`	Run health or connectivity checks. Run without args to view recent check entries

Alerting & Reporting

Command	Description
`mesh-network alert <input>`	Create or log alert events. Run without args to view recent alert entries
`mesh-network report <input>`	Generate operational reports. Run without args to view recent report entries
`mesh-network log <input>`	Record custom log entries. Run without args to view recent log entries
`mesh-network benchmark <input>`	Run or record benchmark results. Run without args to view recent benchmark entries
`mesh-network compare <input>`	Compare configurations or metrics. Run without args to view recent compare entries

Maintenance & Recovery

Command	Description
`mesh-network fix <input>`	Log fix actions or remediation steps. Run without args to view recent fix entries
`mesh-network cleanup <input>`	Record cleanup operations. Run without args to view recent cleanup entries
`mesh-network backup <input>`	Log backup operations. Run without args to view recent backup entries
`mesh-network restore <input>`	Log restore operations. Run without args to view recent restore entries

Utility Commands

Command	Description
`mesh-network stats`	Show summary statistics across all entry types
`mesh-network export <fmt>`	Export all data (formats: `json`, `csv`, `txt`)
`mesh-network search <term>`	Search across all entries by keyword
`mesh-network recent`	Show the 20 most recent activity log entries
`mesh-network status`	Health check — version, data dir, entry count, disk usage
`mesh-network help`	Show usage information and available commands
`mesh-network version`	Show version (v2.0.0)

Data Storage

All data is stored locally in ~/.local/share/mesh-network/:

Each command type has its own log file (e.g., scan.log, monitor.log, alert.log)
Entries are timestamped in YYYY-MM-DD HH:MM|value format
A unified history.log tracks all activity across commands
Export supports JSON, CSV, and plain text formats
No external services or API keys required

Requirements

Bash 4.0+ (uses set -euo pipefail)
Standard UNIX utilities (wc, du, grep, tail, sed, date)
No external dependencies — works on any POSIX-compatible system

When to Use

Network monitoring — Use scan, monitor, and check to track node health, service availability, and connectivity across your mesh network
Incident response — Use alert, fix, and log to document incidents, remediation steps, and resolution timelines
Capacity planning — Use usage, top, and benchmark to track resource consumption and performance baselines over time
Backup & disaster recovery — Use backup, restore, and cleanup to log all maintenance operations with timestamped audit trails
Infrastructure auditing — Use stats, search, compare, and export to review operational history, compare configurations, and generate compliance reports

Examples

bash

# Scan network nodes
mesh-network scan "192.168.1.0/24 — checking all nodes for availability"

# Log a monitoring observation
mesh-network monitor "Node-7 latency spike: 250ms avg over last 15 min"

# Create an alert
mesh-network alert "Disk usage on gateway-01 exceeded 90% threshold"

# Record a fix action
mesh-network fix "Restarted nginx on node-3, cleared stale connections"

# Log a backup operation
mesh-network backup "Full backup of mesh config completed — 2.4GB to /mnt/backup"

# Search for all entries about a specific node
mesh-network search gateway-01

# Export all data as JSON
mesh-network export json

# View overall statistics
mesh-network stats

How It Works

Each operations command (scan, monitor, alert, etc.) works the same way:

With arguments: Saves the input as a new timestamped entry and logs it to history
Without arguments: Displays the 20 most recent entries for that command type

This makes Mesh Network both an operations tool and a searchable ops journal.
