MemCachier supports integration with your New Relic dashboard if you happen to be a customer of both MemCachier and New Relic. Currently this feature is only available to caches of 500MB or larger. A blog post showing the integration can be found here.
To setup the integration you will need to find your New Relic license key. This can be done by going to your "Account Settings" page when logged in to New Relic by click on your New Relic username in the top right corner. Then you will find your license key in the right side information column. It should be exactly 40 characters long. Please refer to the blog post for a visual walkthrough.
Once you have your New Relic licence key, it can be entered for your cache on the analytics dashboard page. In the bottom right corner there is a button to do this.
