Traffic Graph

Enhanced Visualization

The gui_trafficgraph patches provide:

• Non-linear scaling — Better visibility of both small and large traffic
• Separate in/out — Distinct colors for upload/download
• Time range selection — View different time windows
• Tooltips — Exact values on hover

Reading the Graph

Traffic (last hour)
    ▲
  2 │     ╭─╮
MB/s│    ╱  ╲         ╭─╮
  1 │───╱────╲───────╱──╲──
    │  ╱      ╲─────╱    ╲
  0 └─────────────────────────▶
      -60min        -30min    now

    ── Received (download)
    ── Sent (upload)

Traffic Patterns

Normal operation:

• Steady baseline of ~1-10 KB/s
• Spikes when new blocks arrive
• Higher during initial sync

Initial sync:

• Sustained high download (blocks)
• Low upload
• May saturate connection

Serving peers:

• Higher upload if you have many inbound connections
• Spikes when serving historical blocks

Block Propagation

See when new blocks arrive:

Recent Blocks:
│ Height   │ Time       │ From Peer        │ Size    │
├──────────┼────────────┼──────────────────┼─────────┤
│ 870,123  │ 12:34:56   │ 192.168.1.5:8333 │ 1.2 MB  │
│ 870,122  │ 12:24:31   │ xyz...abc.onion  │ 1.8 MB  │
│ 870,121  │ 12:15:02   │ 10.0.0.8:8333    │ 0.9 MB  │

RPC Equivalents

The GUI displays data available via RPC:

# Peer information
bitcoin-cli getpeerinfo

# Network totals
bitcoin-cli getnettotals

# Network info summary
bitcoin-cli getnetworkinfo

# Connection count
bitcoin-cli getconnectioncount

Example: Peer Summary

# Get peer count by network
bitcoin-cli getpeerinfo | jq 'group_by(.network) | map({network: .[0].network, count: length})'

# Output:
# [
#   {"network": "ipv4", "count": 5},
#   {"network": "ipv6", "count": 2},
#   {"network": "onion", "count": 8}
# ]

Example: Traffic Stats

# Total bytes transferred
bitcoin-cli getnettotals

# Output:
# {
#   "totalbytesrecv": 1234567890,
#   "totalbytessent": 987654321,
#   "timemillis": 1699999999999
# }

Connection Health

Indicators

Indicator	Meaning
🟢 Green	Healthy connection
🟡 Yellow	High latency (>500ms)
🔴 Red	Connection issues
⚪ Gray	Disconnected/banned

Healthy Node Signs

• 8+ outbound connections — Good peer diversity
• Some inbound connections — Ports open, helping network
• Mixed network types — IPv4/IPv6/Tor diversity
• Low ping times — under 200ms typically
• Steady traffic — Not stuck or stalled

Warning Signs

• 0 connections — Network issue, check firewall
• Only outbound — Ports not forwarded
• High ban scores — May be misbehaving peer
• No Tor peers — Consider enabling Tor

Configuration Impact

Monitor shows effects of these settings:

bitcoin.conf

# Connection limits
maxconnections=125      # Total peer limit
maxuploadtarget=1000    # Monthly upload limit (MB)

# Network selection
onlynet=ipv4           # Restrict to IPv4
onlynet=onion          # Add Tor peers

# Peer management
addnode=x.x.x.x        # Always try to connect
connect=x.x.x.x        # ONLY connect to these

Debugging Network Issues

No Connections

# Check if listening
bitcoin-cli getnetworkinfo | grep '"localaddresses"'

# Check connection count
bitcoin-cli getconnectioncount

# Try adding a node
bitcoin-cli addnode "seed.bitcoin.sipa.be" onetry

Slow Sync

# Check peer sync status
bitcoin-cli getpeerinfo | jq '.[] | {addr, synced_blocks, inflight}'

# See if stuck on specific peer
# Look for peers with low synced_blocks

High Bandwidth Usage

# Check traffic
bitcoin-cli getnettotals

# Reduce connections if needed
# Edit bitcoin.conf: maxconnections=20

Knots Enhancements

Compared to Bitcoin Core, Knots adds:

Enhancement	Description
Non-linear graph	Better scaling for varying traffic
Network breakdown	Visual IPv4/IPv6/Tor/I2P split
Enhanced tooltips	More detailed hover information
Dark mode support	Proper theming in all views
Block arrival times	See propagation timing

GUI vs CLI Monitoring

Task	GUI	CLI
Quick status check	✓ Best	✓
Automated monitoring	✗	✓ Best
Historical data	✗	✓ (external tools)
Real-time visual	✓ Best	✗
Scriptable	✗	✓ Best

For automated monitoring, consider tools like:

• bitcoin-cli in scripts
• Prometheus + Grafana
• Custom monitoring solutions
