Real-Time Monitoring

Track CPU utilization across all cores:

• Overall CPU percentage
• Per-core breakdown
• Historical trends
• Peak usage indicators

The dashboard displays CPU usage as a percentage (0-100%) with color-coded indicators:

• Green: 0-70% (Normal)
• Yellow: 71-85% (Warning)
• Red: 86-100% (Critical)

Monitor RAM utilization:

• Total memory available
• Used memory (percentage and absolute)
• Free memory
• Memory trends over time

Track storage utilization:

• Per-volume/partition monitoring
• Used vs. available space
• Growth rate analysis
• Low disk space warnings

Monitor network activity:

• Bytes received (RX)
• Bytes transmitted (TX)
• Real-time bandwidth graphs
• Peak bandwidth tracking

The main dashboard provides a high-level view of all agents:

1. Navigate to Dashboard after logging in
2. View the agent list with current status indicators
3. See aggregate metrics across all agents
4. Click on any agent to view detailed metrics

Click on an agent hostname to view detailed metrics:

• Real-time metric graphs (auto-updating every 30 seconds)
• Current values displayed prominently
• Historical data with customizable time ranges
• Comparison with previous periods

View metrics for different time periods:

• Last Hour: See minute-by-minute data
• Last 24 Hours: Hourly aggregates
• Last 7 Days: Daily trends
• Last 30 Days: Monthly patterns (Professional+)
• Custom Range: Select specific dates (Enterprise)

You can configure the polling interval in the agent configuration file:

# Collect metrics every 30 seconds
poll_interval = 30

# Or every 5 minutes
poll_interval = 300

After changing the configuration, restart the agent:

# Linux
sudo systemctl restart astranetmon-agent

# Windows
Restart-Service "AstraNetmon Agent"

# macOS
sudo launchctl unload /Library/LaunchDaemons/com.astranetmon.agent.plist
sudo launchctl load /Library/LaunchDaemons/com.astranetmon.agent.plist

Agent has sent metrics within the last 5 minutes

No metrics received for more than 5 minutes

Common causes:

• Agent service stopped
• Network connectivity issues
• Server shutdown or restart
• Configuration errors

Export metrics directly from the web interface:

1. Navigate to the agent detail page
2. Select your desired time range
3. Click Export or Download CSV
4. Choose the metrics to include
5. Download the CSV file

Programmatically access metrics using the API:

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://your-domain.com/api/v1/metrics?agent_id=agent-123&limit=1000"

See the API Documentation for more details.

• Verify agent is running and status is "Online"
• Check agent logs for errors
• Confirm API key is correct in configuration
• Ensure network connectivity to the API endpoint

• Check for network interruptions during that time
• Review agent logs for errors or restarts
• Verify server wasn't offline or rebooting

• Ensure agent has proper permissions to read system metrics
• Update to the latest agent version
• Check for OS-specific metric calculation differences
