New Relic’s PHP APM can be used on Webscale STRATUS to get transaction traces and fine grained data about what calls are slow. A basic version of New Relic is installed by default on all Webscale STRATUS environments. Webscale STRATUS Support can pull data from New Relic for your store upon request.
When purchasing a New Relic license, please choose the option "Self-Hosted Environment." Stratus currently supports New Relic APM only. Once a license key is received, open a support ticket to have the key added to the Webscale STRATUS environment.
Note: Adding your own license will populate trace data for any transactions over 2 seconds to your New Relic account instead of Webscale's. This will limit Support's ability to assist you with any performance related issues.
