How do I remove suffix and prefix from a search for a dropdown selection in a dashboard?

[askarkz]

Hi,

I have a dashboard with a dropdown selection. For some of the panel further on, I needed to add suffix and prefix to simplify the search. But then I realized that, for another panel, I needed a clean value from the dropdown selection, i.e. w/o prefix and suffix.

How can I remove the prefix and suffix in the panel below? will appreciate an answer.

Thank you!

You just need to create another token like this:

<eval token="NewTokenName">replace(replace($YourExistingToken$, "Prefix ReGex Here", null()), "Suffix RegEx Here", null())</eval>

sorry, i don't think I follow you. very new to splunk... does it need to be in its own panel? and ReGex - is the prefix itself or ReGex expression to remove prefix? appreciate your help

Read the documentation. It is pretty clear and has examples. You need to create a regular expression to match the prefix and another to match the suffix.
