About the Insights page

The Insights page provides insights based on stored log data for your Deliver services. For each service, the page displays the following charts:

• Top 10 5xx Error URLs: The top ten URLs with the highest percentage of 5xx errors.

• Top 10 4xx Error URLs: The top ten URLs with the highest percentage of 4xx errors.

• Top 10 503 Error Responses: The top ten responses with the highest percentage of 503 errors.

  NOTE

  For meaningful insights from Top 10 503 Error Responses, avoid storing values other than legitimate HTTP responses in the response reason when logging data. To change the response to something other than a legitimate HTTP response, consider creating a synthetic response to prevent response field values appearing as redacted information.

• HTTP Request Response Status: The percentage distribution of requests by HTTP response status codes. Clicking on a status type in the graph allows you to drill down to see more information for that particular status type. For example, if you click the bar for 2xx, you can see the percentage of status codes in the 2xx range, and if you click a specific status code, you can see the number of requests for that status code by URL.

• 5xx Errors by Type: The 5xx error types expressed as a percentage of total request volume. Clicking on an error type allows you to see the percentage of errors by URL.

• 4xx Errors by Type: The 4xx error types expressed as a percentage of total request volume. Clicking on an error type allows you to see the percentage of errors by URL.

• Top 10 URLs by Misses: The top ten URLs with the highest percentage of requests that weren't served from cache.

• Top 10 URLs by Bandwidth: The top ten URLs consuming the most bandwidth by percentage.

• Top 10 URLs by Response Time: The top ten URLs taking the most time to serve. Measures the delay between the request sent by the browser and the receiving of the last byte of the related response. Shows the p95 time to last byte.

• Top Browsers By Requests: The top browsers by request percentage. Clicking on a browser type in the graph allows you to see the distribution by browser version.

• Top Devices By Requests: The top devices by request percentage.

• Top OS By Requests The top operating systems by request percentage.

• Top Content Type By Requests: The top content types by request percentage.

• Top 10 URLs by Request: The top ten URLs by request percentage.

• Requests by Client Location: A geographical map showing the request percentage by client location. Hover the cursor over a specific location in the map to display the specific metrics for that location. The table below the map displays for each location the percentage of errors, hits, misses, synthetic responses, and passes.

About the controls on the Insights page

You can access more details for a chart by clicking the expand icon to access the Details page, which contains detailed information about the metric being tracked. Specifically, the Details page typically displays:

• an expanded view of the chart.
• a table that displays a list of up to 100 URLs.
• a button to open the Explorer page to view logs related to the chart

In addition, you can filter the data displayed on the Insights and Details pages by:

• selecting the Service the request was made to.
• entering the Domain the request was made to.
• selecting the Region that received the request.
• selecting the Point of Presence that received the request.
• specifying a Time Range.

Some charts allow you to drill down into the data by clicking the drill down icon . For example, you can drill down into a specific HTTP response code in the HTTP Request Response Status chart to see the top objects returning that HTTP response code. To remove the filter, click the drill up icon or All data.
