renaming search results...

[DTERM]

index=MyApp | stats count by supportGroup, severity

That search provides me a list of events and the severity associated with the events. The severity comes up as 1,2,3,4 or 5. Is there a way for me to rename the severity to something helpful like

1 - low
2 - medium
3 - attention
4 - severe
5 - critical

If you want to do it inline in your search, you can use the eval function case:

index=MyApp 
| eval severityDesc=case(severity==1,"low",severity==2,"medium",severity==3,"attention",severity==4,"severe",severity==5,"critical") 
| stats count by supportGroup, severityDesc

You could also use a lookup table that maps the severity levels to their respective descriptions using information in a CSV file. More information on lookup tables is available in the docs: http://www.splunk.com/base/Documentation/latest/Knowledge/Addfieldsfromexternaldatasources

Hello @Ayn ,

it could be work for numbers only or will work for sting value with some wild entry like below,
MANAGER contains with prefixed value prd so that I'm expecting eval like

   eval name=case(MANAGER==prdehdp* OR prdplhdpx*  OR  *prdasdp*,"prd") |
    eval name1=case(X==dev* ,"dev") |
    eval name2=case(Y==QAT*,"QAT") | stats count by name,name1,name2

Thanks

This solution works great. However, does this imply that I cannot click click on the renamed severity levels now and drill into the results as I could earlier? The results are exactly what I wanted. However, nothing happens when I click on the text string.
