Ploticus/iX

- DISCFREE 3 -

A shell script creates a graphical DISCFREE per Volume Set and Disk like

Remarks:

The whole process to create the needed gifs (and the HTML code) is CPU intensive.
Disc Mirroring is not reflected - that's the reason I show only the percentages.
It is possible to run the script as cgi-bin under a Web Server like Apache/iX but not recommended.
But it is recommended to run this script from time to time as Server User of the Web Server (like SERVER.APACHE) to get the right security for the files.
You may split this script into different parts, of course.
It's just an idea to create all gifs in one run but a different HTML code. You may want to use the gif of the Volume Set as linking image to another HTML page just displaying the gifs of all LDEVs belonging to this volume set.

Example: I stored the script named graph_discfree as SERVER.APACHE in /APACHE/PUB/cgi-bin and run it out of the shell:

/APACHE/PUB/cgi-bin/ > graph_discfree
/APACHE/PUB/cgi-bin/ >

Now I invoke my Browser looking to the URL http://{my_HP3000_Apache_Server}/graph_discfree.htm and I will see the whole Discspace Picture as given in the links of [link]

a small server (less disks) or [link]

a large server (a lot of mirrored disks) .
