How to pass multiple fields in Case or IF commands

Hi Everyone,

I have some events with the field Private_MBytes and host = vmt/vmu/vmd/vmp

I want to create a case when host is either vmt/vmu/vmd and Private_MBytes  > 20000 OR when host is vmp and  Private_MBytes > 40000 then it should display the events with severity_id 4. Example

eval severity_id=if(Private_MBytes >= "20000" AND host IN [vmd*,vmt*,vmu*],4,2)

eval severity_id=if(Private_MBytes >= "40000" AND host ==vmp*,4,2)

 

Note :  if Private_MBytes > 40000, and then if there is any vmd/vmu/vmt it should display severity_id 4 only and for vmp also.

If I must guess, the use of wildcard characters make your search not returning your desired results? (Syntax-wise, I am not sure if IN operator can use square brackets.)  As you only illustrated two values, no need to use case.

| eval severity_id=if(Private_MBytes >= 20000 AND searchmatch("host IN (vmd*,vmt*,vmu*)") OR Private_MBytes >= 40000 AND host LIKE "vmp%", 4, 2)

Hi @devsru ,

you have to correlate your conditions using the boolean operators AND and OR and the parenthesys, aligned with the logic you need:

| eval severity_id=if((Private_MBytes>=20000 AND host IN ("vmd*","vmt*","vmu*")) OR (Private_MBytes>=40000 AND host="vmp*"), 4, 2)

Ciao.
