Hi,

I have a log line the following format:

{  
“Details”:“request”,  
“Other”:{  
“MT”:“123”,  
“St”: 2,  
“Ip”:“192.168.0.9”  
}  
}

I have applied select\_jsonpath to set field from json.  
I need to use lookup table to get some values like parameter mt value 123 i need to replace from lookup to user1 and IP value to host name.

I want to use select\_jsonpath to pipeline json fields.kindly help with the solution to implement lookup along with select\_jsonpath
