DUgen

like agedu but web-based javascript

This was created to interactively visualize file listing output from spectrum scale's policy engine.

To create the data:

• create an output directory for all the files : ex: mkdir myoutput
• server/runPolicy.pl [path_to_analyze] [output_dir] for example: runPolicy.pl /home /tmp/dugen
• you may need to install perl modules such as Parallel::ForkManager
• For the Spectrum Scale Policy Engine, you should set the appropriate nodeclass to run the polcy on. This is at the top of runPolicy.pl:
• my $GPFSPOLICYEXECNODES = "policyServers";
• change policyServers to whatever is appropriate for your site

Output:

• within the output dir you will have a web_reports dir that contains a seperate json.gz file for each subdir under [path_to_analyiz]
• so if you ran it on /home and /home contains /home/foo and /home/bar, there will be two output json.gz files.
• Copy these files to your webservers data/ directory

Viewing:

• upload the git repo to your web server, the index.html should be at the top. data/ contains your json.gz reports, from the output above.
• to view a specific report (for example /home/foo), pass it as an id argument in the URL:
• https://myserver?id=usage_foo
• clicking on the bars will drill down into the dirs

developers

• if you want to supply your own json data, and not use GPFS or policy engines, the javascript will render as long it follows the following standard:

    dirs": [
            {
                "dir": "/",

                "children": [
                    "/dirA", "/dirB"
                ]
            },
