Splunk Search

Splunk dashboard using drilldown showing detailed info, but also sending email alert for us if result > 0

Guys,  I've created a dashboard where I hunt IOCs from OTX intelligence across several logs in Splunk.

This dashboard initially was created to show is some IOC was found, and once we click in the number (stats count command) , then the drilldown executes a second query giving us more information (|table command)

However, besides that, I want the dashboard send us an email in case the count >0 every time, then I used sendemail, however, I cant use the sendemail command where the stats count command is because I will receive an email only with the number 😞

so, I thought about using the sendemail in the second query, however, it only will send the email if one of us CLICK in the number , so, I was trying to find a way to turn the drilldown more automatic, which means, once the result >0, automatically the drilldown would be activated without clicking.

I am wonder if this is possible , or if there is other solution that I can use without giving up the design of the dashboard?

 

Below the dashboard source: 

(pay attention to the lookup that I am doing for domain)

@Luciana 

By setting and unsetting token, you can trigger search to execute it.

Check below example, Here tkn_second_search is set when first search have some count. Please try this XML and let me know if any issue.

<dashboard>
  <label>Single Value Test</label>
  <search id="first_search">
    <query>index = xxx sourcetype=xxx action=Allowed [|inputlookup OTX | search type=URL | rename indicator as url | table url] |dedup user |stats count
    </query>
    <done>
      <condition match="'result.count'!= &quot;0&quot;">
        <set token="tkn_second_search">
index = xxx sourcetype=xxx action=Allowed [|inputlookup OTX | search type=domain OR type=hostname | rename indicator as hostname | table hostname]
|dedup user |table _time, hostname, domain, user, serverip, ClientIP |sendemail to="myemail.co.nz" server=smtp.server.co.nz subject="Notification - IOC found by url" message="This is an test message" sendresults=true inline=true format=csv
        </set>
      </condition>
      <condition>
        <unset token="tkn_second_search"></unset>
      </condition>
    </done>
  </search>
  <row>
    <panel>
      <html>
        Second Search Token = $tkn_second_search$
      </html>
    </panel>
  </row>
  <row>
    <panel>
      <table>
        <search>
          <query>$tkn_second_search$</query>
          <earliest>-24h@h</earliest>
          <latest>now</latest>
        </search>
        <option name="drilldown">none</option>
      </table>
    </panel>
  </row>
</dashboard>

 

My Sample XML:

 

<dashboard>
  <label>Dependent Search Example</label>
  <search id="first_search">
    <query>| makeresults | eval count=1 | table count</query>
    <done>
      <condition match="'result.count'!= &quot;0&quot;">
        <set token="tkn_second_search">| makeresults | eval msg="Hello"</set>
      </condition>
      <condition>
        <unset token="tkn_second_search"></unset>
      </condition>
    </done>
  </search>
  <row>
    <panel>
      <html>
        Second Search Token = $tkn_second_search$
      </html>
    </panel>
  </row>
  <row>
    <panel>
      <table>
        <search>
          <query>$tkn_second_search$</query>
          <earliest>-24h@h</earliest>
          <latest>now</latest>
        </search>
        <option name="drilldown">none</option>
      </table>
    </panel>
  </row>
</dashboard>

@kamlesh_vaghela , I created a new dashboard and copied this new code.

I've created a new dashboard and copied your sample. Is that right?

@Luciana  Just want to ask Why you are adding No event for this table in condition match?

It should be `<condition match="'result.count'!= &quot;0&quot;">` only instead of `            <condition match="'result.count'!= &quot;0No event for this table&quot;">`

 

Let me share my full XML..

@kamlesh_vaghela I want to thank you for all your help. you were right, it was the condition "<condition match="'result.count'!= &quot;0No event for this table&quot;">"

It worked when I've changed the condition back as your suggestion and then, I've hidden all dashboards  with the second search WHEN there are no results.

Thanks again. I really appreciate it.

@kamlesh_vaghela I was using the condition "result.count'!= &quot;0&quot;"

but, in the queries that there were no results found , the panel was showing the message : "Search is waiting for input"

and I thought that it would be confusing for people to understand, so I've changed to 'result.count'!= &quot;0No event for this table&quot;"

In theory, it would do the same, but in my panel it would show 'no result found' which is more understandable.

 

Luciana_0-1624338629126.png

 

let me try to change back to result.count'!= &quot;0&quot; and try again

Hello @kamlesh_vaghela 

thanks for replying me. so, I tried this, but I continue with the same problem which is that I have to CLICK in the number , in order to show me the details inside the 'Information Table' in the bottom. 

I'd like the results would go there WITHOUT clicking if the count != 0

IF I add this condition here:

 

Luciana_0-1623278474841.png

Besides I have to CLICK in the number to the results show up in the "information table' , what happened is when I click the SEARCH window opens to me 😞

Good Morning @kamlesh_vaghela Sorry, I didnt understand the idea. Why Have you sent me this sample dashboard? 🙂 Do you want that I fill out all queries from my old dashboard to this one?

Hi @kamlesh_vaghela , How are you?

look, I am considering that I cant do what I want because drilldown always will be requiring that user clicks.

but actually , what I want is IF the search stats count >=1 then, a second search would be trigger and then, in this search I could use the sendemail command to send me alert with more information

 

so, considering  first query:

index = xxx sourcetype=xxx action=Allowed [|inputlookup OTX | search type=URL | rename indicator as url | table url] |dedup user |stats count

 

 <condition match="$result.resultCount$>1">

then run a second query: 

index = xxx sourcetype=xxx action=Allowed [|inputlookup OTX | search type=domain OR type=hostname | rename indicator as hostname | table hostname]
|dedup user |table _time, hostname, domain, user, serverip, ClientIP |sendemail to="myemail.co.nz" server=smtp.server.co.nz subject="Notification - IOC found by url" message="This is an test message" sendresults=true inline=true format=csv

 

Do you know if is possible, or How Can I do this?

I thought about set a token with 
<condition match="$result.resultCount$>1">

but then , I dont know how to trigger a second search if the condition is true.

 

Thank you so much

By setting and unsetting token, you can trigger search to execute it.

Check below example, Here tkn_second_search is set when first search have some count. Please try this XML and let me know if any issue.

<dashboard>
  <label>Single Value Test</label>
  <search id="first_search">
    <query>index = xxx sourcetype=xxx action=Allowed [|inputlookup OTX | search type=URL | rename indicator as url | table url] |dedup user |stats count
    </query>
    <done>
      <condition match="'result.count'!= &quot;0&quot;">
        <set token="tkn_second_search">
index = xxx sourcetype=xxx action=Allowed [|inputlookup OTX | search type=domain OR type=hostname | rename indicator as hostname | table hostname]
|dedup user |table _time, hostname, domain, user, serverip, ClientIP |sendemail to="myemail.co.nz" server=smtp.server.co.nz subject="Notification - IOC found by url" message="This is an test message" sendresults=true inline=true format=csv

@kamlesh_vaghela  I hope you are having a good day! so, I've tried and it worked, now every time the first query has a result count > 0 the second search triggers and send an email 🙂 

Can I confirm with you if I understood  right the idea of: result.count'!= &quot;0&quot;"

( in case there are no results >=0, then it will show no results found?)

I thought about using the same logic for all queries in my dashboard, then, as for an example, I did a test in 3 queries , however in the query that we dont have any IOC is found (hits by URL - $tkn_first_search$) , it is appearing for me " search is waiting for input"

Below code is just for Debugging purpose. You can remove it.

<row>
    <panel>
      <html>
        Second Search Token = $tkn_second_search$
      </html>
    </panel>
  </row>

 

Just use depends If you don't want to show panel with when token is not set. see below code.

<row>
    <panel depends="$tkn_second_search$">
      <table>
        <search>
          <query>$tkn_second_search$</query>
          <earliest>-24h@h</earliest>
          <latest>now</latest>
        </search>
        <option name="drilldown">none</option>
      </table>
    </panel>
  </row>

@kamlesh_vaghela  thanks for all your help and I swear that is my last message🙂 

I've just changed the condition for : <condition match="'result.count'!= &quot;0No event for this table&quot;"> then it will show 'no results count. 🙂

now, I am trying to add all my query results in ONE panel. I was checking your answer in the following https://community.splunk.com/t5/Dashboards-Visualizations/How-to-add-two-query-results-in-xml-dashbo...

but,  I m not sure if I can use 2 different tokens (condition match that triggers my second query) and ($job.sid$) for the first query

Can you just confirm?

Yes @Luciana 

You can define multiple tokens and use it. 🙂

ok @kamlesh_vaghela  I will try to set different tokens. 🙂

Have you noticed that in the solution that you helped me has a little issue... once we set that token, the SECOND SEARCH will not run a second time if the FIRST SEARCH runs again? Do you know How Can I get this around?

 

for example, the stats count that was in RED changed to green, which means 0 IOCs found, but the bottom panel continues to show me the oldest result .
