SqlMetrics
A simple gem to track metric events in your own postgres or Amazon Redshift database.
Features
- Asynchronously stores events into Postgres or Amazon Redshift based db
- Filters commonly known bots by default
- Uses geoip gem to extract city/country from client ip's
Todo
- Batch inserting events to db to improve performance under very high load
- Track Users (just because thats a common thing to do besides tracking raw events)
- Offer SQL based dashboard that allows to run custom queries and also render charts
Installation
Add this line to your application's Gemfile:
gem 'sql_metrics'
And then execute:
$ bundle
Or install it yourself as:
$ gem install sql_metrics
Usage
Setup database and table
Tell the gem how to connect to your db. So simply create a file called sql_metrics.rb into your config/libs folder with the config:
SqlMetrics.configure do |config|
config.host = '127.0.0.1'
config.db_name = 'my_metrics_db'
config.user = 'my_postgres_user'
config.password = 'my_password'
end
Then to create the required events table just run this rake task:
rake sql_metrics:create_events_table
Track a event
A simple event can look like this:
SqlMetrics.track(
'event_name',
{
:a_property => 'hello world',
:another_property => 'hello user'
}
)
You can also pass a rails request object from a controller:
SqlMetrics.track(
'event_name',
{
:a_property => 'hello world',
:another_property => 'hello user'
},
request
)
The gem automatically filters bots for you using the user_agent property from the rails request object...you can disable this if you want:
SqlMetrics.track(
'event_name',
{
:a_property => 'hello world',
:another_property => 'hello user'
},
request,
{
:filter_bots => false
}
)
The gem also automatically performs a geo lookup using the remote_ip property from the rails request object...you can disable this if you want:
SqlMetrics.track(
'event_name',
{
:a_property => 'hello world',
:another_property => 'hello user'
},
request,
{
:geo_lookup => false
}
)
This will automatically fetch properties like the user agent, client ip, requested url, etc
