On the statistics tab of your account page, you can find useful graphs to help see how ImageEngine is working on your site. These graphs are provided to you to help you keep track of your ImageEngine usage and keep an eye on any anomalies that can affect the performance of ImageEngine or your site.

In addition to the per-engine analytics, we offer a traffic report to help you better understand the amount of traffic ImageEngineserved within a specific date range.

Engine Analytics

On the Analytics tab of an Engine, you can find useful graphs to help see how ImageEngine is working on your site. 

To access the Analytics tab from the sidebar you must first select the Engine you would like to see Analytics for. The Analytics tab may be accessed while viewing any of the pages within a single Engine.

All graphs have time frame buttons above the graph to allow you to view various ranges of data.
Once you access the analytics tab, you will see the following graphs:

Cache Hit Ratio

This graph shows the percentage of images that are being served from ImageEngine servers (a cache hit) versus the amount being served from the Origin (a cache miss). The pie chart can be viewed for the last hour, the last day, and the past 7 days

A high amount of cache misses can mean many things; from low traffic in a region to new images being updated on the website. One option to consider if you wish to increase your cache hit rate is to increase the time to live (TTL) of images.

Image Payload Reduction

This graph presents a histogram of the Original bytes requested through ImageEngine, showing how much ImageEngine has reduced the payload of images. The total SmartBytes is displayed, as well as the Image Payload Reduction as a percentage. This is a useful way to see how efficiently ImageEngine is serving compressed images. You can view this information for the last hour, last 24 hours, last 7 days, the current month, last month, and the last 30 days.

Bandwidth Saved

This is a timeline that shows the amount of bandwidth used by ImageEngine compared to the bandwidth that would have been used by the Original Images. You can view this for the last 7 days and the last 30 days

Requests

This is a timeline of the number of requests being made to this Delivery Address. You can use this graph in conjunction with other graphs to see if any strange numbers can be explained by a spike or fall in traffic. You can view this information for the last 24 hours, last 7 days, the current month, and the last 30 days.

Smartbytes Used

This Graph displays the total number of Smartbytes used on a daily basis. Views available are the current month, last 30 days.
