I have a url, by hitting which, i get some data. Is it possible in splunk to read that data and process it and display the processed content in a dashboard.
that url points to a text file which has Ones and Zeroes. I need to interpret them and display some content based on which in a tabular fashion
(Weird, my post got truncated. Trying again)
Assuming you don't need to manipulate that data, you can just represent it with an iframe within an html panel. I'd post an example but it looks like answers.splunk.com kicks out any iframe so the code sample won't fly in here.
So instead of an example, just check out this page and use the same syntax: http://www.w3schools.com/tags/tag_iframe.asp
iframes might fail if the external page is http but splunk is https (for security reasons).
