Splunk Search

Graph from key/value pairs

Hello,

I am extracting from a database the list of the largest 20 tables. The format would be something like =:

For example:

TableSizeMB
LargestTable=2012
VeryLargeTable=2008
SomeTable=500

Obviously, the list is not fixed as some tables might become larger and make it to the list while others would disappear.

Would it be possible to have a graph of these tables and their sizes? If yes, how should I define the search?

Thank you in advance.

As far as the search, it's pretty much trivial

your search that gets tablename and tablesize
| sort 20 - tablesize

If you want to display all 20, then in splunk I'd suggest using a horizontal bar chart. Here's some run-anywhere sample code so you can see what it looks like.

| makeresults | eval junk=mvrange(1,25) | mvexpand junk | eval tablename="T".junk | eval tablesize = random()%125 + random()%221 | sort 20 - tablesize | table tablename tablesize
