Read-only VMware vCenter/ESXi monitoring — 8 tools, code-level safety. No destructive operations exist in this codebase.

Why a separate repository? VMware Monitor is fully independent from VMware-AIops. Safety is enforced at the code level: no power off, delete, create, reconfigure, snapshot-create/revert/delete, clone, or migrate functions exist in this codebase. Not just prompt constraints — zero destructive code paths.

Webhook	Slack, Discord, or any HTTP endpoint
Daemon Management	daemon start/stop/status, PID file, graceful shutdown

5. Safety Features

Feature	Details
Code-Level Isolation	Independent repository — zero destructive functions in codebase
Audit Trail	All queries logged to ~/.vmware-monitor/audit.log (JSONL)
Password Protection	.env file loading with permission check (warn if not 600)
SSL Self-signed Support	disableSslCertValidation — only for ESXi with self-signed certs in isolated labs; production should use CA-signed certificates
Prompt Injection Protection	vSphere event messages and host logs are truncated, sanitized, and wrapped in boundary markers
Webhook Data Scope	Sends monitoring summaries to user-configured URLs only — no third-party services by default
Production Recommended	AI agents can misinterpret context and execute unintended destructive operations — real-world incidents have shown AI-driven tools deleting production databases and entire environments. VMware-Monitor eliminates this risk: no destructive code paths exist. Use VMware-AIops only in dev/lab environments

What's NOT Included (By Design)

These operations do not exist in this repository:

• ❌ Power on/off, reset, suspend VMs
• ❌ Create, delete, reconfigure VMs
• ❌ Create, revert, delete snapshots
• ❌ Clone or migrate VMs
• ❌ _double_confirm, _show_state_preview, _validate_vm_params

For these operations, use the full VMware-AIops repository.

Common Workflows

Daily Health Check

1. Check alarms: vmware-monitor health alarms --target prod-vcenter
2. Review recent events: vmware-monitor health events --hours 24 --severity warning
3. List hosts: vmware-monitor inventory hosts — check connection state and memory usage

Investigate a Specific VM

1. Find the VM: vmware-monitor inventory vms --power-state poweredOff
2. Get details: vmware-monitor vm info problem-vm
3. Check related events: vmware-monitor health events --hours 48

Set Up Continuous Monitoring

1. Configure webhook in ~/.vmware-monitor/config.yaml
2. Start daemon: vmware-monitor daemon start
3. Daemon scans every 15 min, sends alerts to Slack/Discord

---

Troubleshooting

Alarms returns empty but vCenter shows alarms

The get_alarms tool queries triggered alarms at the root folder level. Some alarms are entity-specific — try checking events instead: vmware-monitor health events --hours 1 --severity info.

"Connection refused" error

1. Run vmware-monitor doctor to diagnose
2. Verify target hostname/IP and port (443) in config.yaml
3. For self-signed certs: set disableSslCertValidation: true

Events returns too many results

Use severity filter: --severity warning (default) filters out info-level events. Use --hours 4 to narrow the time range.

VM info shows "guest_os: unknown"

VMware Tools not installed or not running in the guest. Install/start VMware Tools for guest OS detection, IP address, and guest family info.

Doctor passes but commands fail with timeout

vCenter may be under heavy load. Try targeting a specific ESXi host directly instead of vCenter, or increase connection timeout in config.yaml.

Installation

Step 0: Prerequisites

# Python 3.10+ required
python3 --version

# Node.js 18+ required for Gemini CLI and Codex CLI
node --version

Step 1: Clone & Install Python Backend

git clone https://github.com/zw008/VMware-Monitor.git
cd VMware-Monitor
python3 -m venv .venv
source .venv/bin/activate
pip install -e .

Step 2: Configure

mkdir -p ~/.vmware-monitor
cp config.example.yaml ~/.vmware-monitor/config.yaml
# Edit config.yaml with your vCenter/ESXi targets

Set passwords via .env file (recommended):

cp .env.example ~/.vmware-monitor/.env
chmod 600 ~/.vmware-monitor/.env
# Edit and fill in your passwords

Security note: Prefer .env file over command-line export to avoid passwords appearing in shell history. config.yaml stores only hostnames, ports, and a reference to the .env file — it does not contain passwords or tokens. All secrets are stored exclusively in .env (chmod 600). Webhook notifications are disabled by default; when enabled, payloads contain no credentials, IPs, or PII — only aggregated alert metadata sent to user-configured URLs only. We recommend using a least-privilege read-only vCenter service account.

Password environment variable naming convention:

VMWARE_{TARGET_NAME_UPPER}_PASSWORD
# Replace hyphens with underscores, UPPERCASE
# Example: target "home-esxi" → VMWARE_HOME_ESXI_PASSWORD
# Example: target "prod-vcenter" → VMWARE_PROD_VCENTER_PASSWORD

Step 3: Connect Your AI Tool

Choose one (or more) of the following:

---

Option A: Claude Code (Marketplace)

Method 1: Marketplace (recommended)

In Claude Code, run:

/plugin marketplace add zw008/VMware-Monitor
/plugin install vmware-monitor

Then use:

/vmware-monitor:vmware-monitor
> Show me all VMs on esxi-lab.example.com

Method 2: Local install

# Clone and symlink
git clone https://github.com/zw008/VMware-Monitor.git
ln -sf $(pwd)/VMware-Monitor ~/.claude/plugins/marketplaces/vmware-monitor

# Register marketplace
python3 -c "
import json, pathlib
f = pathlib.Path.home() / '.claude/plugins/known_marketplaces.json'
d = json.loads(f.read_text()) if f.exists() else {}
d['vmware-monitor'] = {
    'source': {'source': 'github', 'repo': 'zw008/VMware-Monitor'},
    'installLocation': str(pathlib.Path.home() / '.claude/plugins/marketplaces/vmware-monitor')
}
f.write_text(json.dumps(d, indent=2))
"

# Enable plugin
python3 -c "
import json, pathlib
f = pathlib.Path.home() / '.claude/settings.json'
d = json.loads(f.read_text()) if f.exists() else {}
d.setdefault('enabledPlugins', {})['vmware-monitor@vmware-monitor'] = True
f.write_text(json.dumps(d, indent=2))
"

Restart Claude Code, then:

/vmware-monitor:vmware-monitor

---

Option B: Gemini CLI

# Install Gemini CLI
npm install -g @google/gemini-cli

# Install the extension from the cloned repo
gemini extensions install ./gemini-extension

# Or install directly from GitHub
# gemini extensions install https://github.com/zw008/VMware-Monitor

Then start Gemini CLI:

gemini
> Show me all VMs on my ESXi host

---

Option C: OpenAI Codex CLI

# Install Codex CLI
npm i -g @openai/codex
# Or on macOS:
# brew install --cask codex

# Copy skill to Codex skills directory
mkdir -p ~/.codex/skills/vmware-monitor
cp codex-skill/SKILL.md ~/.codex/skills/vmware-monitor/SKILL.md

# Copy AGENTS.md to project root
cp codex-skill/AGENTS.md ./AGENTS.md

Then start Codex CLI:

codex --enable skills
> List all VMs on my ESXi

---

Option D: Aider (supports local models)

# Install Aider
pip install aider-chat

# Install Ollama for local models (optional)
# macOS:
brew install ollama
ollama pull qwen2.5-coder:32b

# Run with cloud API
aider --conventions codex-skill/AGENTS.md

# Or with local model via Ollama
aider --conventions codex-skill/AGENTS.md \
  --model ollama/qwen2.5-coder:32b

---

Option E: Continue CLI (supports local models)

# Install Continue CLI
npm i -g @continuedev/cli

# Copy rules file
mkdir -p .continue/rules
cp codex-skill/AGENTS.md .continue/rules/vmware-monitor.md

Configure ~/.continue/config.yaml for local model:

models:
  - name: local-coder
    provider: ollama
    model: qwen2.5-coder:32b

Then:

cn
> Check ESXi health and alarms

---

Option F: Trae IDE

Copy the rules file to your project's .trae/rules/ directory:

mkdir -p .trae/rules
cp trae-rules/project_rules.md .trae/rules/project_rules.md

Trae IDE's Builder Mode reads .trae/rules/ Markdown files at startup.

Note: You can also install Claude Code extension in Trae IDE and use .claude/skills/ format directly.

---

Option G: Kimi Code CLI

# Copy skill file to Kimi skills directory
mkdir -p ~/.kimi/skills/vmware-monitor
cp kimi-skill/SKILL.md ~/.kimi/skills/vmware-monitor/SKILL.md

---

Option H: MCP Server (Smithery / Glama / Claude Desktop)

The MCP server exposes VMware read-only monitoring as tools via the Model Context Protocol. Works with any MCP-compatible client (Claude Desktop, Cursor, etc.).

# Run directly (after uv tool install)
uvx --from vmware-monitor vmware-monitor-mcp

# Or if already on PATH
vmware-monitor-mcp

# With a custom config path
VMWARE_MONITOR_CONFIG=/path/to/config.yaml uvx --from vmware-monitor vmware-monitor-mcp

Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "vmware-monitor": {
      "command": "uvx",
      "args": ["--from", "vmware-monitor", "vmware-monitor-mcp"],
      "env": {
        "VMWARE_MONITOR_CONFIG": "/path/to/config.yaml"
      }
    }
  }
}

Install via Smithery:

npx -y @smithery/cli install @zw008/VMware-Monitor --client claude

---

Option I: Standalone CLI (no AI)

# Already installed in Step 1
source .venv/bin/activate

vmware-monitor inventory vms --target home-esxi
vmware-monitor health alarms --target home-esxi
vmware-monitor vm info my-vm --target home-esxi
