The where command uses the same expression syntax as the eval command. Also, both commands interpret quoted strings as literals. If the string is not quoted, it is treated as a field name.

Yes, the file hashes are the same for the first 2. By looking at the hashes, you can see which one is legit and which one is not. A novel way you can use EDR data in Splunk is to generate a list of known filenames and hashes and store it in a lookup table or KV-store to compare against. index=edr | dedup *filehash | table filename, *filehash ...One catch is if the value is C then the subsequent graphs don't have anything to display. Example. The queries display account numbers, but the value for C is invalid account number (aka null) so the resulting charts are all blank. What I'd like to do is if the token is =C then unset the token so the resulting charts never show.Solution. 11-12-2014 06:45 PM. Main's value should be test1 / test2 / test3 / test4 in-case test1 is empty option goes to test2, if test2 is empty then option goes to test 3 and test4 like wise. If suppose test1, test2, test3, test4 contains value then test1 would be assigned to main. if not "All Test are Null" will be assigned to main.How to Left Join is NULL. fearloess.

So, where user="NULL" searches for events where the user field really exists and has that value, whereas where isnull (user) looks for events that doesn't have that value at all. You would achive the same with " search NOT user=* ". Because isnull (user) means that the field doesn't exist, isnull (user) AND mvcount (user)=1 will never match. 3 ...I think that stats will give you a 0 for the count if there are no matching events, not null.

ThanksYes, the issue is with the null values for return (although in your example, return is an empty string not null) - try extracting the array, mvexpand, then extract the fields - this saves on doing the mvzip and split as well.
