Problem
Cisco Splunk Enterprise is awesome and the Splunk GUI is, too. However sometimes you need to quickly search the result data.
Solution
My coworker and friend Malte created a 100% client-side browser bookmarklet (see https://de.wikipedia.org/wiki/Bookmarklet) which enables you to search your data in the browser GUI fast and easily. Works fine with Firefox and Chrome with Splunk Enterprise v10.0 and v10.2.
Demo:
How it works under the hood
There is no magic - just client-side browser DOM work:- It finds Splunks classic result tables by their CSS classes (table-chrome, results-table, and friends).
- It injects a scoped stylesheet (all classes are namespaced with bm-, for bookmarklet) so it never clobbers Splunk's own styles.
- Filtering is pure client-side: it reads each cell's text, compares it against your tags, and toggles row visibility.
- Page merging watches the paginator, waits for the active page to change, then splices the new rows back into the master table.
Everything is client-side: no external network calls, no telemetry, no data leaves the page.
Caveats
It is built for Cisco Splunks classic UI. So it won't work on the newer Splunk Dashboard Studio dashboards. And the page-merge feature does re-trigger searches as it clicks through — handy, but worth using gently on a busy shared search head.Installation
- Open Browser (Chrome, Firefox)
- Create a bookmark and insert the following javascript as URL:
https://github.com/flostyen/SplunkMalteBeautifier/blob/main/bookmarkletjavascript:(function(){const splunkTables=document.querySelectorAll('.results-table .table, table.table-chrome');if(splunkTables.length===0){alert('No classic Splunk dashboard or search tables found.');return}if(!document.getElementById('splunk-bookmarklet-styles')){const
