CSV Lookup for search query

keyu921 — Fri, 28 Aug 2020 02:45:02 GMT

I prepared csv to inputlookup to compare the Splunk logs.

adhoc.csv

Account,

test01,etc....

test02,etc....

my Query

index=msad sourcetype=msad [| inputlookup adhoc.csv | fields Account]
Searching Period: Last 24 hours

Cross check adhoc.csv match the searching logs.

For those account did not perform any authentation which logs stored at index=msad, during search period, then show zero values.

Hi @keyu921

It's not overly clear what you are asking for so I not going to try, however if you want to have an OR statement generated for you base search, from the adhoc.csv file, then you need to use the format command, as shown

... your search ... [| inputlookup adhoc.csv | fields Account | format] | ...

Substituted result of the subsearch would be

... your search ... ( ( Account="test1" ) OR ( Account="test2" ) ) | ...

Having said that, more often than not, the use of the lookup command is far more efficient ...

... your search ... | lookup adhoc.csv Account AS Account OUTPUTNEW <...some new field in adhoc.csv...> | where isnotnull(<some new field>)

Check the Splunk docs for more details, if interested.

Hope this helps

This will show you all the Account names from the CSV that did NOT have any entries in the msad log in the time period given. It first searches and counts all the data for the monitored accounts, then adds back all the accounts being monitored and just then looks for ones with no count value.

Hope this helps

Hi @keyu921,

please try this:

In this way,

total>o means that there are logs,
total=0 means that there aren't logs.

As you requested, I added at the end a filter to display only the ones without logs, but you could also create a dashboard displaying all the Accounts with their status.

Ciao.
