Unknown search command 'isnull'

Hi,

I am trying the following search syntax in Splunk to build out a report of our top 25 riskiest systems. But when I run it, I get “Unknown search command 'isnull'” message.

Thanks in advance!

Hi @sakanet  I have "approximately" edited your query, still lot of editings needed I think.  (this tip will be useful to you.... you can copy paste your search query into splunk search bar and press "Ctrl and \", which will format your search query in a readable style..)

Hi @inventsekar ,I really appreciate your time and effort! I tried it and got the following two errors:

Error in 'eval' command: The expression is malformed.
The search job has failed due to an error. You may be able view the job in the 
 
Luckily, the person originally gave me this query fixed it. Apparently when it was copied and pasted, it messed up the formatting.
This is what worked:
I tried putting the code in </> as HTML/XML but when I submit, it says: "Your post has been changed because invalid HTML was found in the message body. The invalid HTML has been removed. Please review the message and submit the message when you are satisfied." I am not sure what language you guys select when you share code.)

Hi renjith_nair, 

I just signed up last night and posted this question, I swear I did not see all the formatting tools, it was late at night, maybe I just missed them.

This code was given to me by someone else. I am very new to this, I will try to reach out to him and see if he can help.

Thanks!

Hi @sakanet 

its difficult and confusing to edit/update your query(the "|" are misplaced ).. so lets do this step by step.. 

this is the format of the "isnull" command(isnull always works inside the "eval")

| eval VULNID = if(isnull(cpe_vendor), pluginName, VULNID)

now, you can edit your query accordingly and then copy paste the query, then, we will edit/correct the typing issues.
