5 Test your pixel

HOME > SNOWPLOW SETUP GUIDE > Step 1: setup a Collector > [Setup the Cloudfront collector](setting up the cloudfront collector) > 5. Test your pixel

Wait 10-15 minutes after creating the Cloudfront distribution before running the following test. (As it takes a little bit for the Cloudfront setup to complete...) Now try accessing your pixel over both HTTP and HTTPS using a browser, wget or curl:

https://{{SUBDOMAIN}}.cloudfront.net/i

If you have any problems, then double-check your CloudFront distribution's URL, and check the permissions on your pixel: it must be Openable by Everyone.

That's it - you now have a CloudFront distribution which can serve your tracking pixel fast to anybody anywhere in the world and log the request to Amazon S3 in your snowplow-logs bucket.

## A note on non-production environments

At the moment, the Snowplow ETL process does not have a facility for filtering out events generated by your development or test environments.

For this reason, we strongly recommend that you also self-host a second tracking pixel, to serve as a kind of /dev/null for Snowplow events in your development and test environments.

A couple of notes on this approach:

• You would need to configure your web application to use the correct CloudFront account ID depending on environment
• Unless you want to analyse your development or test environment, disable logging on the CloudFront distribution for your pixel

If you prefer, the Snowplow Analytics team maintains a publically available /dev/null tracking pixel on this account ID:

All done?

You are now ready to setup a tracker.
