PeakHour 3.0.6 – Visualize and analyze your network traffic.

PeakHour 3.0.6

PeakHour is a beautiful, real-time network-traffic visualizer that lives in your menu bar. It provides an instant view of your Internet or WiFi activity in real-time. PeakHour is great for monitoring your Internet or WiFi connection, and can help you determine how much bandwidth your computers and devices are using at any given time.

Note: PeakHour requires a capable, SNMPv1-enabled device to work properly. Many good routers do support SNMP but not all do, so it is important that you check before purchasing. Use the tool in the Related Links to find out if your router is compatible.

What’s New

Version 3.0.6:

  • Improved: Status bar icon is now grayscale to better reflect the modern OS X aesthetic
  • Improved: Added prompt to launch automatically on startup.
  • Improved: Better graph scaling levels and defaults.
  • Improved: Upgraded to latest net-snmp library.
  • Improved: General enhancements to the Configuration Assistant UI, in particular to assist with first-time setup.
  • Improved: Upgrade Offer browser window now displays padlock to indicate secure TLS connection.
  • Improved: Added locking to UPnP queries; should prevent UPnP devices 'flapping' between active and unreachable state when Configuration Assistant is open.
  • Improved: UPnP now tries to fuzzy-match device names if one can't be matched via UUID. This may help with some routers that don't maintain a stable UUID (i.e. change their UUID on reboot or reconnect).
  • Fixed: Major improvements to SNMPv3 support. Now correctly uses SNMPv3 for all queries; previously would mistakenly send some queries with SNMPv1/v2c causing unpredictable results.
  • Fixed: Logging occasionally stopped working after waking from sleep.
  • Fixed: "Hide if Unreachable" checkbox in C now wired up correctly in Configuration Assistant.
  • Fixed: "Launch automatically when computer starts" working again (despite Xcode's best efforts to the contrary).
