GEMINI Portal

The GEMINI Portal allows you to easily visualize and monitor a slice. It gives a graphical overview of the slice and quick access to each node's measurements. Through the Portal you can:

  • see the experiment's topology
  • display measurement graphs for a node or link, updated in real time
  • access each node's Live View (Passive Measurements) web page
  • access each node's Active Measurements
  • create an Archive point
  • access Archived points

Log On

The portal can be accessed at https://geminiportal.netlab.uky.edu/. Please accept our self-signed certificate.

Log on using the information given on the handout.

Enter your slice information into the log on form.

  • User Name used to create the slice.
  • Certificate Issuer the certificate issuer (clearinghouse) associated with your User Name.
  • Slice Name name of slice to be shown.
  • Password password given when slice was instrumentized.
  • Click Map Slice button to see the mapped layout of the slice topology.

Overview

The initial overview contains a geographic map with the slice's nodes represented by terminal icons.

The global node, or measurement controller is labeled with an MC icon .

To the right is a control group that lists the slice's name along with the following controls.

  • Top item is the Slice Name.
  • Logout to logout of the portal.
  • Archive opens the archiving page where you can save and view archive points.
  • Overview resizes map to show all nodes.
  • Collapse All or Expand All expands or collapses nodes that are in the same geographic location. Expanded nodes are relocated so that they are all visible instead of collocated.
  • Node Name Each node is listed. Click on the magnifying glass to zoom in and center the node. Click on the name to just center the node on the screen.

Control forms

Clicking on a Machine Node, MC or Link line brings up a Control form

  • Machine Node
    • Link to the node's Live View page (All Graphs).
    • A list of check boxes for showing the node's graphs. Checked graphs are shown to the left of the map.

  • MC
    • Passive Link to the Passive Measurements via INSTOOLS Live View
    • pSConfig Link
    • perfAdmin Link to perfSonar admin pages.

  • Link
    • A list of check boxes for showing the link's graphs. Checked graphs are shown to the left of the map.

Graphs

To add a graph, open the control form for the node or link by clicking on it. Select the check boxes and the corresponding graphs will be shown on the left of the page. Mouseover a graph to enlarge it. Click on a graph to bring up its control form. Double click a graph to open it into its own window.
