How to get a populatingSearch to dynamically populate a drop-down menu?

cjrash1 — Tue, 14 Jun 2016 02:23:36 GMT

All -

I have been trying to implement the findings from a few other posts, but I just cannot get this figured out. I am trying to populate a drop-down based on active DHCP requests. I can get the list of IPs with this search:

index=bro sourcetype=bro_dhcp | sort by src_ip | dedup src_ip | table src_ip

BUT I cannot get it to implement in the drop-down menu.

I have done massive amounts of deleting, and this is what I am left with:

  <label>DNS Requests By IP</label>  
  <fieldset submitButton="false" autoRun="false">
    <input type="dropdown" token="inIP">
    <label>Current DHCP Leases: </label>
      <populatingSearch fieldForValue="src_ip" fieldForLabel="src_ip">
        sourcetype=bro_dhcp | fields src_ip | dedup src_ip
      </populatingSearch>
 </input> 
  </fieldset>
</form>

Any help would be amazing.

Try this

<label>DNS Requests By IP</label>
<fieldset submitButton="false" autoRun="false">
    <input type="dropdown" token="inIP">
        <label>Current DHCP Leases: </label>
        <search>
        <query>
           sourcetype=bro_dhcp | fields src_ip | dedup src_ip
        </query>
        </search>
        <fieldForLabel>src_ip</fieldForLabel>
        <fieldForValue>src_ip</fieldForValue>
    </input>
</fieldset>
</form>

Awesome. I only had to make one edit and it worked. Added the index into the search
index=bro sourcetype=bro_dhcp earliest=-7d| fields + src_ip | dedup src_ip | sort by src_ip
