How do I rename a Rex field?

[sid_1435]

Hi , 

I want to rename to Required Parameters Longitude and Latitude are missing or invalid to a new value Required Parameters missing.

index="****" k8s.namespace.name="*****" "Error" OR "Exception" | rex field=_raw "(?<error_msg>Required Parameters Longitude and Latitude are missing or invalid)" | stats count by error_msg | sort count desc

Any help will be great

| eval error_msg=if(match(_raw, "Required Parameters Longitude and Latitude are missing or invalid"),"Required Parameters missing", error_msg)

Hi Again,

I have the drilldown on the field 

Required Parameters Longitude and Latitude are missing or invalid

But since we have renamed  it to 

Required Parameters missing

it is sending  renamed value as parameter , rather i want the original value as parameter

Can you please suggest how to do that

Add a condition to the drilldown so that if the value is "Required Parameters missing" change it to "Required Parameters Longitude and Latitude are missing or invalid" in the drilldown action

Use | rex with SED mode

| makeresults
| eval error_msg = "Required Parameters Longitude and Latitude are missing or invalid"
| rex field=error_msg mode=sed "s/(Required Parameters) .* (missing) .*/\1 \2/g"
