To ensure all 18+ telemetry graphs (Latency, Jitter, Packet Loss, etc.) show accurate real-time data, please ensure your network equipment and firewalls are configured with the following parameters:

• ICMP (PING): Enable Echo Request/Reply. Required for high-fidelity Latency, Jitter, and Packet Loss tracking.
• SNMP (PORT 161): Open UDP Port 161. Required for Battery, Fan, Humidity, and remote Hardware telemetry.
• SNMP COMMUNITY: Ensure your 'Community String' (default: public) matches your ZCOM dashboard configuration.
• HOST RESOURCES MIB: Your device must support RFC 2790 for remote CPU and Uptime tracking to function.
• DNS MONITORING: If monitoring via Port 53, ensure both TCP and UDP traffic is permitted for heartbeat verification.
• ICMP RATE LIMITING: Adjust ICMP policing on your edge router to prevent artificial 'Packet Loss' during high-frequency polling.
• FIREWALL ALLOWLIST: Ensure ZCOM NOC IP addresses are permitted to prevent 'OFFLINE' false positives.
• MTU OPTIMIZATION: Ensure MTU is set to 1500 (or 1400 for tunneled links) to prevent fragmentation in Throughput analytics.

PRO-TIER: ADVANCED SNMP & AGENT CONFIGURATION

For maximum fidelity and zero-firewall telemetry, we recommend implementing the ZCOM Heartbeat Agent or advanced Net-SNMP extensions.

1. Net-SNMP Generic Extensions (Linux/Unix)

Add these OIDs to your /etc/snmp/snmpd.conf to unlock advanced system metrics:

# RAM Usage (Host Resources MIB)
1.3.6.1.2.1.25.2.3.1

# Load Average
1.3.6.1.4.1.2021.10.1.3.1

# Disk Usage
1.3.6.1.2.1.25.2.3.1.6.1

2. Interface Auto-Indexing & Throughput

Use the SCAN button in the SNMP Configuration panel to automatically detect and map your primary internet interface for 100% accurate throughput graphing.

3. ZCOM Heartbeat Agent (Python)

For servers behind strict firewalls, use this push-based agent to inject metrics directly into the NOC:

import requests, psutil, time
# Strategic Heartbeat Agent
while True:
    m = {"cpu_usage": psutil.cpu_percent(), "status": "ONLINE"}
    requests.post("https://zcomnetworkservices.com/api/agent/push", 
                  json={"order_id": "YOUR_ID", "slot_index": 0, "metrics": m})
    time.sleep(60)

For comprehensive monitoring, please permit the following traffic patterns on your edge security gateway:

The ZCOM Dashboard utilizes simultaneous data streams to populate all 18+ graphs:

• SLOT IP DATA: Generates high-precision Heartbeat (Status), Latency, Jitter, and Packet Loss analytics.
• SNMP DATA: Pulls hardware-level telemetry including Battery Backup, Fan Velocity, Ambient Humidity, Remote CPU Load, and System Uptime.
• NOC BACKBONE DATA: Provides environmental and security metrics such as Intrusion Attempts, Encryption Entropy, DNS Speed, and Link Throughput.
