# ExecutionTime

[![Listed on OpenSource-Heroes.com](https://opensource-heroes.com/badge-v1.svg)](https://opensource-heroes.com/r/igorkasyanchuk/execution_time)

Monitor execution time and other metrics directly in `rails console`, similar to what you see after each request.

`[METRICS]  Completed in 908.3ms | Allocations: 2894 | ActiveRecord: 0.9ms (queries: 13)`

 

## Usage

Just add this gem to the Gemfile and start `rails c`. After this try to do something like `User.first`.

If you want to measure few lines of code just wrap it with `begin/end`:

```ruby

[4] pry(main)> begin

[4] pry(main)*   User.first.first_name.size

[4] pry(main)*   a = User.count + 1

[4] pry(main)*   b = User.second.last_name.size

[4] pry(main)* end  

  User Load (0.4ms)  SELECT "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT $1  [["LIMIT", 1]]

   (3.6ms)  SELECT COUNT(*) FROM "users"

  User Load (0.3ms)  SELECT "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT $1 OFFSET $2  [["LIMIT", 1], ["OFFSET", 1]]

[METRICS]  Completed in 6.8ms | Allocations: 839 | ActiveRecord: 4.3ms (queries: 3)

=> 5

```

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'execution_time'

```

## First run

Sometime you can see that there are more SQL queries or allocated objects because Ruby is just loading objects in memory or verifying connection to the DB.

## How to disable/enable metrics output in the console

If you need to disable gem in the console you can do it by `ExecutionTime.disable!`. And later enable with `ExecutionTime.enable!`.

By default gem is enabled.
