# System Health Monitoring Daemon

A robust system health monitoring daemon that tracks hardware status and automatically creates tickets for detected issues.

## Features

- Comprehensive system health monitoring:
  - Drive health (SMART status and disk usage)
  - Memory usage
  - CPU utilization 
  - Network connectivity (Management and Ceph networks)
- Automatic ticket creation for detected issues
- Configurable thresholds and monitoring parameters
- Dry-run mode for testing
- Systemd integration for automated daily checks

## Installation

1. Copy the service and timer files to systemd:
```bash
sudo cp hwmon.service /etc/systemd/system/
sudo cp hwmon.timer /etc/systemd/system/
```
2. Reload systemd daemon:
```bash
sudo systemctl daemon-reload
```
3. Enable and start the timer:
```bash
sudo systemctl enable hwmon.timer
sudo systemctl start hwmon.timer
```


## Manual Execution

1. Run the daemon with dry-run mode to test:
```bash
python3 hwmonDaemon.py --dry-run
```
2. Run the daemon normally:
```bash
python3 hwmonDaemon.py
```


## Configuration

The daemon monitors:

- Disk usage (warns at 80%, critical at 90%)
- Memory usage (warns at 80%)
- CPU usage (warns at 80%)
- Network connectivity to management (10.10.10.1) and Ceph (10.10.90.1) networks
- SMART status of physical drives

## Ticket Creation

The daemon automatically creates tickets with:

- Standardized titles including hostname, hardware type, and scope
- Detailed descriptions of detected issues
- Priority levels based on severity (P2-P4)
- Proper categorization and status tracking

## Dependencies

- Python 3
- Required Python packages:
  - psutil
  - requests
  - smartmontools (for SMART disk monitoring)

## Service Configuration

The daemon runs:

- Daily via systemd timer
- As root user for hardware access
- With automatic restart on failure

## Security Note

Ensure proper network security measures are in place as the service downloads and executes code from a specified URL.
