HI,  
In my logstash layer I am receiving the cf loggregator message in json format.  
Example:  
{ "name" : "abc", "address" : "bangalore}

If I want to search in my logstash grok filter, if "name":"abc" is present in the message then do some specific action.  
Can you please tell how can we achieve this?

Here I want to check complete concatenated string: "name":"abc"

THanks in advance.

Hi Satya,

You could use a regex conditional.
