The Public Test Grid

Live Demo

the publically writeable directory through testgrid.allmydata.org. Here is the welcome page which has a list of connected nodes, recent uploads and downloads, and performance statistics.

How To Connect To The Public Test Grid

The test grid is subject to being updated at random times, so compatibility is likely to break without notice. Also note that many upgrades require all files and directories to be flushed, especially as storage formats change.

The test grid is currently running an 1.0.0-compatible release (see "My versions" on the welcome page for the current version of the web gateway server).

After installing the code according to docs/install.html, copy the following file into its base directory:

file namefile contents
introducer.furlpb://todjw7qkb4dgq4fkeo7cqydcu5vneioh@tahoecs2.allmydata.com:52106/introducer

Then run tahoe start.

We created a shared public directory: feel free to use it for experimentation -- once your node is up and listening on port 3456, this URL should give you access to that directory.

Test Grid Statistics

Usage statistics are available for the public test grid. (Note: ticket #13 mentions other graphs and changes that need to happen on this page)

Count of how many clients and servers are connected to the grid

Space used by the shared public directory

This counts the total size of all immutable files reachable through the shared public directory listed above.

Load Average

This measures how long a 1 second callback is overdue, on each machine that connects to the central 'stats gatherer'.

Same, but those the peak value (reset at node reboot)

Total space consumed in grid

This queries each storage server for how much space it is currently consuming.
