View and Understand CDN Analytics

Overview

After you create a site, you can use this document learn about the different analytics available in the StackPath Control Portal. 

StackPath provides near real-time insights to help you stay informed of your site performance. All analytics are reported in 5-minute intervals and are typically up to date within 10 minutes. 

View CDN analytics

1. In the StackPath Control Portal, in the left-side navigation, click Sites. 
2. Locate and select the desired site. 
3. In the left-side navigation, click Analytics. 
4. Click CDN.
5. In the top, right corner of the screen, you can use the time frame tool to configure the displayed data. 
   • When you select a new time frame, data in this screen will automatically refresh. 
6. Review the following analytics:

   Type of analytic	Description
   Bandwidth Usage	This line graph displays the throughput as an aggregation of bytes per second. Specifically, the line graph displays: The throughput for the CDN to end users. This information is labeled as Edge.  The throughput for the CDN pulling from your origin. This information is labeled as Origin.
   Bandwidth Rate	This line graph displays: The amount of bandwidth used to deliver CDN assets.   This information is labeled as Edge.  The amount of bandwidth used to perform origin pulls.  This information is labeled as Origin.
   Requests	This line graph displays: The number of individual HTTP requests handled by the CDN. This information is labeled as Edge.  The number of requests that were sent to the origin for assets that were not in cache.  This information is labeled as Origin.
   Delivery by Data Center	This bubble map displays the StackPath data centers that delivered your content, as well as the amount of content delivered.
   Cache Hit Ratio	These graphs display the proportion of traffic that required access to your origin for transfers and requests.  This data displays a high-level view of how efficiently you use the CDN's cache, based on bytes-transferred ratios and individual-hit ratios. The higher the ratios, the more efficiently you use the CDN. For Transfer Hit Ratio, this metric is displayed as a line chart, where the origin bandwidth rate is plotted in Mbps. This ratio is reflected by the amount of data delivered from CDN cache divided by the total amount of data delivered by the CDN (including cache misses). High hit ratios indicate that a large amount of CDN data was delivered with a small number of origin pulls. If you are pulling your CDN Analytics from our API, then these plotted values are represented by the CDO.xferRateMeanMbps metric. For Request Hit Ratio, this metric is also displayed as a line chart, where the number of origin requests per second are plotted in RPS. This ratio reflects the number of requests to the CDN cache divided by the total number of requests to the CDN (including requests that resulted in origin pulls). High hit ratios indicate a large number of hits from the CDN with a small number of requests to the origin. These plotted values are equal to the CDO.rpsMean API metric.
