Portal Dashboard

The Dashboard is your home page in the COSMOS Portal — the first thing you see after logging in. It provides a quick overview of your account, your recent testbed activity, and convenient links to the most commonly used portal features.

Profile Card

At the top of the Dashboard, a profile card displays your key account information:

  • Name — your full name as registered
  • Username — your testbed login name (used for SSH access to console servers)
  • Email — your registered email address (used for notifications and password reset)
  • Organization — the research group you belong to
  • Account Created — the date your account was approved

Below the profile card, you will find quick-action links to Edit Profile and SSH Keys, saving you the extra click of navigating through the user menu.

Usage Statistics

The Dashboard displays three categories of usage statistics to help you understand your testbed utilization:

Disk Usage

Shows the total storage space you are consuming across all NFS-mounted home directories on the testbed. The value is displayed in gigabytes (GB). Every testbed console server mounts a shared NFS filesystem, so files you create on one console are visible on all others. If your disk usage is approaching the quota, consider cleaning up temporary files, experiment logs, and old disk images you no longer need.

Reservation Statistics

Two numbers are shown:

  • All-time reservations — the total number of reservations you have ever made across all testbed domains
  • Last 4 weeks — how many reservations you made in the past 28 days

These numbers help you track your usage patterns. The testbed's fairness algorithm for resolving reservation conflicts uses recent usage (past 2 weeks) as a factor — users who have used the testbed less recently are given priority when two users compete for the same time slot.

Login Sessions

Shows the total SSH session time and the number of individual login sessions across all testbed consoles. This data is collected from the last command on each console server and aggregated daily.

Note: Usage statistics are updated approximately every 24 hours and may not reflect your most recent activity.

Community Forum

Directly below the Dashboard link in the sidebar, you will see a Community Forum link. Clicking it opens the COSMOS community discussion forum in a popup window (700 x 800 pixels) that you can position alongside the main portal. The forum uses single sign-on — if you are logged into the portal, you are automatically authenticated in the forum without entering your credentials again.

If other users have posted new topics or replied to discussions you are participating in, a small red notification badge appears next to the Community Forum link showing the number of unread items. The badge updates automatically every 60 seconds.

See Community Forum for full details on using the forum.
