Solved: Re: How to clear/reset the value of a token?

Mario · ‎06-09-2022

Hello all.

I am making a dashboard in which I was in the need to create a subsearch. This is the piece of code that does it:

<panel>
<title>random panel title</title>
<table depends="$show_debug$">
<search id="Build_list">
<query>index= here it goes my query |fields * |table important_field |format</query>
<finalized>
<condition match=" 'job.resultCount' != 0">
<set token="my_list">$result.search$</set>
</condition>
<condition>
<unset token="my_list"></unset>
</condition>
</finalized>
</search>
<option name="drilldown">none</option>
</table>
</panel>
</row>
<row>
<panel>
<title>another panel</title>
<html depends="$show_debug$">
<h3>$my_list$</h3>
</html>
</panel>

and here I am using the $my_list$ token:

<search>
<query>$my_list$ | foreach
something.* [rename "<<FIELD>>" as
"<<MATCHSEG1>>"]
| stats
values(Url),values(UrlDomain)</query>
<earliest>$earliest$</earliest>
<latest>$latest$</latest>
</search>

This worked well the first time, but now, for every new query I do, no matter if I close and open a new browser/splunk session, I see still the results of the first query I did. is like $my_list$ has the first ever values hardened and I cannot reset them. I though that <unset token="my_list"></unset> would clear it but not....

Any help please? The goal here is to use this $my_list$ token, which is a splunk query (note the |format at the end of the query) but of course this token needs to be empty every time I run a new query.

Thanks a lot in advance.

Hi @Mario,

in the input section, you could add a panel like this (obviously to adapt to your tokes:

    <input type="radio" token="resetTokens" searchWhenChanged="true">
      <label></label>
      <choice value="reset">Reset Inputs</choice>
      <choice value="retain">Retain</choice>
      <default>retain</default>
      <change>
        <condition value="reset">
          <unset token="token1"></unset>
          <unset token="token2"></unset>
          <unset token="token3"></unset>
          <set token="resetTokens">retain</set>
        </condition>
      </change>
    </input>

Ciao.

how would I do this with a *link* field type? I just want a button that says 'SUBMIT" so the user can reset the tokens.

Hi @makelovenotwar,

you can do this using a JavaScript, but I'm not an expert in JS so I cannot help you more.

But using my solution, you have a reset button in the header bar.

Hi Giuseppe!

It's very useful, but this soluton needs to restart the search.

My needing is that one panel is related via token to another: when I click on a field in the second panel the previous show only related record. How can I reset the token in order to have all the records in the first panel without restart the search?

Thanks a lot!

Extending a previously answered question is perhaps not the best way of getting your question answered, particularly when the extension is a bit vague. Please start a new question with more specifics about your particular usecase and the difficulties you are having i.e. what would you want the solution to look like.

Hi @maspiro ,

for my knowledge, restarting the search is the only way to reset a token.

Ciao Beppe!

I am so sorry I thought I marked your reply as solution before. I have just done it now.

Grazie mille!

This solution is for classic dashboard. How do it in Dashboard studio ?

You need to use another search to (conditionally) set the result field to null and use the results tokens from the search. For example:

{
    "visualizations": {
        "viz_F0Z9jsFU": {
            "type": "splunk.singlevalue",

                "primary": "ds_eZ6LtdAT"
            },
            "options": {
                "unit": "km/h"
