Power Sentry Deploy Proxmox

PowerSentry Deploy — Proxmox Worker Daemon

Overview

Deploys the PowerSentry worker agent (daemon + CLI) to a Proxmox host or any target server. Supports both direct connections and multi-hop SSH via a jump/bastion host.

Prerequisites

• SSH access to the target host (via jump host if needed)
• SSH key: ~/.ssh/id_ed25519 (or specify a different key in SSH_BASE)
• Python 3 on the target host
• The .env file configured with your network specifics OR pass values as CLI args

.env Configuration

Create or update proxmox-power-monitor/.env:

PROXMOX_HOST=192.168.1.104       # IP of the target Proxmox host
JUMP_HOST=100.86.93.41           # Optional: bastion/jump host IP (leave empty for direct)
JUMP_USER=ubuntu                 # Jump host SSH username
REMOTE_USER=root                 # Target host SSH username (usually root for Proxmox)

Deployment Steps

1. Copy .env from template (if not already done)

cd proxmox-power-monitor
cp .env.example .env
# Edit .env with your actual IPs and credentials

2. Run deploy script

With jump host (multi-hop):

cd proxmox-power-monitor
./deploy.sh <proxmox-host> <jump-host>
# Example: ./deploy.sh 192.168.1.104 100.86.93.41

Direct connection (no jump host):

cd proxmox-power-monitor
./deploy.sh <target-ip>
# Example: ./deploy.sh 192.168.1.104

The script will:

1. Load .env if present (values can be overridden by CLI args)
2. Check connectivity (jump host if specified, then target)
3. Verify Python 3 availability on target
4. Install websockets Python package
5. Create remote directory structure (/opt/proxmox-power-monitor)
6. Copy all Python files to the target
7. Set permissions

3. SSH into target and install the service

# Via jump host
ssh -o IdentitiesOnly=yes -o IdentityFile=~/.ssh/id_ed25519 \
    -J ubuntu@<jump-host> root@<proxmox-host>

# Or directly
ssh -o IdentitiesOnly=yes -o IdentityFile=~/.ssh/id_ed25519 root@<target-ip>

4. Install and start the worker

cd /opt/proxmox-power-monitor

# Install as systemd service (standalone mode)
python3 cli.py install

# Install with control panel connection
python3 cli.py install --control-panel=ws://<control-panel-host>:8765/worker

# Start the daemon
python3 cli.py start

# Verify it's running
python3 cli.py status

5. Verify metrics

# Check stats
python3 cli.py stats --total
python3 cli.py stats --recent=10

# Project costs
python3 cli.py project 14

What Gets Deployed

Service Management

# Check status
systemctl status powersentry-worker

# View logs
journalctl -u powersentry-worker -f

# Uninstall
cd /opt/proxmox-power-monitor
python3 cli.py uninstall

Troubleshooting

Connection refused to control panel:

• Verify control panel is running: systemctl status powersency-control-panel
• Check network connectivity: ping <control-panel-host>
• Test WebSocket: wscat -c ws://<control-panel>:8765/worker

No metrics appearing:

• Check daemon logs: journalctl -u powersentry-worker -f
• Verify database permissions: ls -la /var/lib/proxmox-power-monitor/
• Restart daemon: python3 cli.py restart

Deploy script fails:

• Verify jump host connectivity if using one
• Check SSH key permissions: chmod 600 ~/.ssh/id_ed25519
• Ensure Python 3 is available on target: which python3
