Help require to define calculate field

[sumitkathpal]

Hi All,

I need to calculate field base on the below scenario.

need to create a new field signature but when field securityService = Antimalware then new signature field equals to securityService "" malwareCategory and if securityService = Antispam then signature field equals to securityService "" verdict .

Thanks in advance

Create a Calculated Field called signature defined like this:

case(securityService == "Antimalware", securityService "_"  malwareCategory, securityService == "Antispam", securityService "_" verdict, true(), "BROKEN/FIXME")

Thanks @woodcock but if we add three fields than it stops working

case(securityService == "Antimalware", securityService + "" + malwareCategory, securityService == "Antispam", securityService + "" + verdict, true(), "BROKEN/FIXME") (This on is working under calculated field)

case(securityService == "Antimalware", securityService + "" + malwareCategory +""+ category , securityService == "Antispam", securityService + "" + verdict + "" + category , true(), "BROKEN/FIXME") (This on is working when you use this under search using eval command but when you define it under calculated field it stops working)

please go through the eval documentation here https://docs.splunk.com/Documentation/Splunk/7.2.6/SearchReference/Eval and here
https://docs.splunk.com/Documentation/Splunk/7.2.6/Search/Usetheevalcommandandfunctions
eval can be used with if, case just like other programming languages
Your requirement is also not very clear, you say - when field securityService = Antimalware then new signature field equals to securityService and you give an example in bold
securityService = Antispam then signature field equals to securityService
So when securityService = both Antispam or Antimalware your signature field should eval out to securityService?
What is the difference when you are setting the securityService feild to the same value?
