Extract a value of the field as count

[geeksk01]

I have a log like this 

{"module": “x”, "app_name": “sample”-app, "message": "Number of  Transactions :52”}. I need to extract the value 52 as count.

I can use    eval c1=substr(message,25,2) . But how can I use as count variable. I want to use this count to compare with another count

What's wrong with what you have?  You have the count in a field called 'c1' so you should be able to compare with another count using eval.

| eval match = if(c1 == count, "Yes", "No")
