# unicorn-instruments
This is a hack in order to account for the total time spent in ruby while processing http requests.
## Usage
```ruby
gem 'unicorn-instruments'
```
Require the gem in your unincorn config file.
config/unicorn.rb
```ruby
require 'unicorn-instruments'
...
```
## Synopsis
```
Start a timer.
Call accept().
Call send().
Close socket.
Stop timer.
Print Elapsed time.
```
If the timer elapsed for 4ms, the following log line will be printed:
```
measure=unicorn.process val=4
```
Using this data with [l2met](https://github.com/ryandotsmith/l2met) you can plot the unicorn processing time with the router service time. The difference between the values will be the time spent in the Heroku network.
