How to perform nested if conditions in Splunk

[naveenurs]

Example 1:

uatoken0=Linux
uatoken1=U
uatoken2=Android
uatoken3=en-us

Example 2:

uatoken0=Linux
uatoken1=Android 4.2.2
uatoken2=en-us

Example 3:
uatoken0=iPad
uatoken1=CPU OS 6_1_3 like Mac OS X
uatoken2=

I want to achieve the following:

**if** (uatoken0="Linux" **AND** **if** uatoken1="U")==**TRUE** 
**then** OS=uatoken2
**else if**(uatoken0="Linux" **AND** **if** uatoken1="Android 4.2.2"
**then** OS=uatoken1
**else** OS=uatoken0;

This is what I have accomplished so far:

|eval uatokentmp=split(uatoken,";")
|eval uatoken0=mvindex(uatokentmp,0)
|eval uatoken1=mvindex(uatokentmp,1)
|eval uatoken2=mvindex(uatokentmp,2)
|eval uatoken3=mvindex(uatokentmp,3)
|eval uatoken4=mvindex(uatokentmp,4)
| eval uatoken5=mvindex(uatokentmp,5)
|eval OS=if(mvindex(uatokentmp,0)="Linux",
    (if(mvindex(uatokentmp,1)="U",
                mvindex(uatokentmp,2),
                mvindex(uatokentmp,1))),
    mvindex(uatokentmp,0)) 
| table OS uatoken0 uatoken1 uatoken2 uatoken3 uatoken4 uatoken5
|sort OS

This works for Example 2 and Example 3. However, it fails for Example 1. The output for Example 1 is OS="U".

I am not able to figure out what is wrong. Need another set of eyes to go through my code and help me.
If there is a better way to do this, please advise.

This is the original query that I was trying to run when I posted the question:
eventtype=video|eval uatokentmp=split(uatoken,";")
|eval uatoken0=mvindex(uatokentmp,0)
|eval uatoken1=mvindex(uatokentmp,1)
|eval uatoken2=mvindex(uatokentmp,2)
|eval uatoken3=mvindex(uatokentmp,3)
|eval uatoken4=mvindex(uatokentmp,4)
| eval uatoken5=mvindex(uatokentmp,5)
|eval OS=if(mvindex(uatokentmp,0)="Linux",
(if(mvindex(uatokentmp,1)="U",
mvindex(uatokentmp,2),
mvindex(uatokentmp,1))),
mvindex(uatokentmp,0))
| table OS uatoken0 uatoken1 uatoken2 uatoken3 uatoken4 uatoken5
|sort OS

[Ayn]

Uh, I don't see you using the suggested solutions at all in your search?

[naveenurs]

I am not able to post it in the comments for some reason. So, I updated the post. I have also added the sample output.

[lguinn2]

Can you post the exact search string that you are now using? Thanks!

[naveenurs]

match has not helped.

OS uatoken0 uatoken1 uatoken2 uatoken3 uatoken4 uatoken5
Linux Linux U Android 2.2.1 en-us SAMSUNG-SGH-I997 Build/FROYO

As you can see, OS is still showing as Linux and not Android.

[naveenurs]

Thanks to both of you! Appreciate your help.

[lguinn2]

I second @Ayn's suggestion of the user agent parser.

[Ayn]

That's not a problem with case itself, that's something that depends on what you feed case with. In your case, you'll want to use match which performs regular expression matching against whatever field you want to use.

case(match(uatoken1,"^Android") ...

As a sidenote, if you're going into user agent parsing territory, godspeed. You might want to consider using the excellent user agent parser app that's available on splunkbase: http://splunk-base.splunk.com/apps/48017/ta-uas_parser

[naveenurs]

Thanks for responding.

Using case has a problem. I will not be able to use wildcard character for Android to select all android versions. Essentially, my query should be if uatoken1=="Android*"

[lguinn2]

This should do it..

| eval OS = case(uatoken0=="Linux" AND uatoken1=="U", uatoken2,
                 uatoken0=="Linux" AND uatoken1=="Android 4.2.2", uatoken1,
                 1==1, uatoken0)

And as @Ayn mentions above, you can use the match() function as well...

| eval OS = case(match(uatoken0,"(?i)Linux") AND uatoken1=="U", uatoken2,
                 match(uatoken0,"(?i)Linux") AND match(uatoken1,"(?i)Android"), uatoken1,
                 1==1, uatoken0)

Note that my regexes above are set to be case-insensitive. The matches are simply looking for that string at any position within the variable's text.

Note that the case function conditions are evaluated in order; the first condition that evaluates to true is accepted and the remainder are ignored. So order of the clauses is important.
