inputlookup - count of values including Null

warren — Wed, 15 Nov 2023 10:49:15 GMT

Hello,

I have a lookup file and I would like to use it to search a dataset and return a table showing each entry in the lookup file with a count of their number of matches in the main dataset including displaying the entries from the lookup file which have a null value.

I've tried a number of techniques, the closet I have come is:

dataFeedTypeId=AS
[| inputlookup approvedsenders
| fields Value
| return 1000 $Value]
| stats count as cnt_sender by sender

But this only shows the lookup fileentries with non-zero values (n.b. I am manually adding 1000 to the return to make it work, that's a different problem)

I have also tried:

This shows all the values in the lookup file but shows a zero count against each one.

Thank you in advance.

Your second search should work - is it just a simple lookup e.g. not wildcard or CIDR match? Do you have a typo in your actual search?

@ITWhisperer at the moment it is just a simple lookup, there are values in the table which match the log data exactly. The first example does return the correct results (without the null values).

Value is the information from the lookup file.

sender is the information from the main dataset

cnt_sender is a variable used within the code

Is that how it should be?

If sender is the field in the dataset, then it should be something like this

@ITWhisperer Thank you so much, that has returned the results I was expecting.
