Using the UC San Diego Network Traffic Weathermap

Learn how to use UCSD's Network Weathermap to look at current traffic conditions on our campus data communications network.

View the UCSD network's current traffic levels, including traffic along various cross-campus segments, at http://weathermap.ucsd.edu/.  You must be using UCSD's wired or wireless network, or the VPN, to connect to this page.

The color of a pipe indicates the current percentage of usage of 10 Gigabits of bandwidth along that pathway. (Even if the pipe is 20G or 30G, the percentage will show as if it were a 10G pipe.)

View the connectivity of a given node switch to nearby buildings.

  • To view images of the connectivity of a given node switch to nearby buildings, hover over that switch name
    • For example, hovering over ERC/Muir/Marshall shows you how node A, which serves those areas, is connected to the buildings in those areas.
  • Clicking on the switch name takes you to a new window where only that image is displayed.
  • Clicking on the switch can be helpful sometimes because, depending on the size of the user's display, hovering over the node may not display the image properly. In this case clicking on the switch name will present the image correctly.

View traffic details for a specific connection.

  • To see traffic details for a given pipe, hover over the number in the box on that pipe.
  • Clicking on this image takes you to more extensive statistics and traffic details for that pipe.

Troubleshoot unexpected behavior.

  • Flickering images: If you are using a laptop or other small screen, hovering over a particularly large image may cause flickering rather than image display. Clicking on the item will bring up a window where the image can be seen clearly.
  • Sticky images: Once you've clicked on an image and go back to the Weathermap, it doesn't want to let go of the image you've viewed.  Wiggle the mouse to make this go away.
