How to write a search to extract String and Total fields to include in my table of results?

lksridhar — Sat, 03 Dec 2016 07:32:53 GMT

Hello Everyone,

I am new to Splunk and trying to write the search below to display the below data in my dashboard, but I'm not getting the expected result.

Search:

index=ABC source=*.log | rex field=_raw ".Total +(?[0-9]+)" | dedup _raw | table String _time Total

I'm getting the string and _time data in my dashboard, but I'm not getting Total value because the total is not extracted as a default field and getting below format.

_time    String    Total
aaaa     bbbb 
aaaa     bbbb

My sample data here.

Nov 30, 2016 09:31:04 AM CST ABCD (BaseABCD.java:139)
- <==      Total: 351

Could you any one help me to write the search to display the total value in my dashboard?

Thanks.

Your rex command should look like the following:

rex field=_raw "Total:\s(?<Total>.\d+)"

Running a dedup on _raw is not a good idea. I am not sure whether it will change anything in the search result except making the search run slower.

If you are new to regular expressions you can alternatively try erex command (read on Splunk documentation).

Also, once you have validated that rex command is working as expected then, create a field extraction using "Extract New Fields" option. Splunk will interactively create field extraction regular expressions for you based on selected value in the list of events. It will show how many events matched and unmatched the regular expression. It will also allow your to provide your own regular expression where you can override with the regular expression used in rex command.

Reason why Interactive Field Extraction is better is because this is saved as a Knowledge Object and hence the extracted field is automatically available at search time when you specify the index/sourcetype. ALso you dont need to rewrite the rex command for every search/report/alert/dashboard and maintenance/modifications will remain at a single place (Splunk > Settings > Knowledge > Fields > Field extractions)

In order to test your regular expressions on sample events you can use regex101 website.

Hi Niketnilay,

Thanks for quick response. I have tried with the new query, but it is not showing total value on the dashboard. I have used the below query. Could you pls check and correct the search?

index=ABC source="abcd/efgh/ijklm" SearchController OR Transaction | rex field=_raw "Total:\s(?.\d+)" | Table String, _time, Total.

Can you whether your base search is returning results or not?

index=ABC source="abcd/efgh/ijklm" SearchController OR Transaction

I had checked the your sample data on regex101

Nov 30, 2016 09:31:04 AM CST ABCD (BaseABCD.java:139)
- <== Total: 351

and following regular expression was working fine

Total:\s(?<Total>.\d+)

Could you also please confirm whether there is actually a newline character before - <== Total: 351 or not? If possible add sample data as is from your logs.

Thanks of your information, now i can able to see the data under the total value but i am not getting any data for under the string filed.

see the sample log files details.

Nov 30, 2016 07:34:25 AM CST INFO (TransactionController.java:159) - String=[Entered Get Transaction Authorization For Transactrion Id], Long=[111111]
Nov 30, 2016 09:31:04 AM CST DEBUG (BaseJdbcLogger.java:139) - <==      Total: 351

search:

 index=ABC source="abcd/efgh/ijklm" SearchController OR Transaction  | | rex field=_raw "Total:\s(?.\d+)" | Table String, _time, Total

Output:

-time Total String
222 1233 No Data
222 1234
223 4567

Could you please help me on this to get the string details in the result?

Do you want the following to be string?

DEBUG (BaseJdbcLogger.java:139)

Re: How to write a search to extract String and Total fields to include in my table of results?

niketn — Mon, 05 Dec 2016 18:40:09 GMT

Following will extract Both String and Total using rex. However, do try out Interactive Field Extraction to ensure that your regular expression is matching all required events.

rex field=_raw "^\w{3}\s\d{2}\,\s\d{4}\s\d{2}\:\d{2}\:\d{2}\s(A|P)M\sCST\s(?<String>.*) \- \<\=\= Total:\s(?<Total>\d+)"

Further looking at your sample data and search query. Try to add sourcetype in base search instead or source. If you are using source, I hope you have wildcard included.

Your base search also filter out only required contents like "CST DEBUG" and "- <== Total:" should be present in your base search.

I am not sure what does the following do in your base search SearchController OR Transaction, since it is not a field I was expecting them to be a part of the logs.

I had checked my previous regular expression on Regex101. Not sure what is not working. Maybe some special character in the actual data that you have is not showing up properly in Splunk Answers post here. So try a simpler extract. Basically, I am trying to get everything between CST and Total as String.

index=ABC source="abcd/efgh/ijklm" SearchController OR Transaction | rex field=_raw "\sCST\s(?<String>\.*)\sTotal:\s(?.\d+)" | Table String, _time, Total

Further if you are not experienced with Regular Expressions try erex and definitely do this through Interactive Field Extraction (Splunk will write the regular expression for you).

yes, search controller OR transaction is part of the log file. let me explain the customer requirement. customer want to display below table format in dashboard.

-time Result_Count total_search_time
12/6/16 10:02:04.000 AM 60 34.267

When clicking on this row the following information should display in the next screen
