Example application: Read Evaluate Print Loop

Its a text processing application. Following is the schematic of application

loop;
    accept text input from STDIN;
    process the text data;
    print the processed output to STDOUT;

Each loop we consider it as a text processing Job

The application is refereed from https://github.com/census-instrumentation

Lets see it in action

export GO111MODULE=on
go build -o repl main.go

Whats the problem then?

We want metrics about

1. Total number of jobs is been processed?
2. How much time it is taking to process an one job?
3. In each job how much amount of data it is processing?

Step-1 : Application

Run the application

go build -o repl main.go
