Use Edge Insights to gain historical and near real-time insights into threat profiles, performance, and CDN usage. It allows you to:
Generate a report for security violations and CDN usage.
Visualize where and how your content is being requested.
Troubleshoot issues by analyzing security violations and delivery profiles for problematic traffic.
Export data as a JSON file.
The primary function of these reports is to identify threat profiles, assess performance, and gather data on CDN usage. This data should not be used for billing purposes.
Generating a report consists of performing the following steps:
Navigate to the Edge Insights page.
From the Edgecast Console, select the desired private space or organization.
Select the desired property.
From the left-hand pane, select the desired environment from under the Environments section.
From the left-hand pane, select Edge Insights.
Select one of the following data sources:
Access Logs: Use this data source to analyze CDN traffic for up to the last 6 hours.
Bot Manager Alerts: Use this data source to view bot manager rule violations for up to the last 7 days.
Edge Control: Use this data source to analyze how recent CDN deployments affects content delivery and performance.
Downsampled Access Logs: Use this data source to analyze CDN traffic, downsampled to 0.1%, for up to the last 7 days.
Rate Limiting Alerts: Use this data source to view traffic that exceeded your rate limit(s), downsampled to 10%, for up to the last 30 days.
WAF Alerts: Use this data source to view access rule, custom rule, and managed rule violations of your Security Application configurations for up to the last 30 days.
RUM Logs: Use this data source to view Core Web Vitals (CWV) data that were tracked through our Real User Monitoring (RUM) library. This log data is available for up to the last 7 days.
Edge Function Logs: Use this data source to view log messages for edge functions that were computed within the last 7 days. Log messages through the log() method (e.g., console.log("My message")).
Internal Logs (FE): Reserved for internal use.
Cloud Functions Logs: Use this data source to view Cloud Functions log data for up to the last 24 hours.
Security Logs: Use this data source to view access rule, rate limiting, bot manager, custom rule, and managed rule violations of your Security Application configurations for up to the last 7 days.
Select the time period for which data will be returned.
Define a time period that does not exceed the retention period defined for the selected data source.
Optional. Define a filter for your report to gain deeper insights into security violations, key fields, or traffic patterns.
Edge Control Only: Define the configurations that will be compared and the type of data that will be analyzed.
From the Customer config version section, select two or more configurations.
Select the data that will be compared from the HTTP Status Code and Cache Status sections.
For example, you may select TCP_MISS from the Cache Status section to compare whether cache misses increased as a result of your latest configuration update.
The following common use cases are provided to demonstrate various ways in which you may use Edge Insights to gain insight into traffic patterns or to troubleshoot issues.
From the Data Source option, select Access Logs (Full - last 6 hours).
From the Time Period option, define the desired time period.
For example, if the software update was made available on a Monday at 3 p.m., then you would set the starting point to that date and time. By default, the ending point is automatically set to a recent timestamp and therefore allows you to view all available data from the starting point to the present.
Create a filter for the software update’s URL.
Click on + Add Filter.
Select URL Path.
Set it to the URL path for the desired software update package.
Specific URL Path Example: The following value filters for a specific URL:
/downloads/widgets.zip
Recursive Example: The following value filters for all requests with the same base URL:
regex:/downloads/.*
Click Save.
From the Top Results section, select the Country Name field.
From the pie chart, click on United States.
From the Top Results section, select the HTTP Status Code field.
Review the status codes.
Optional. Dig into a specific status code by clicking on it and then reviewing log entries from the Logs section.
Specific Data: Click on the icon next to the data that you would like to share. Edgecast will load the corresponding JSON data in a new window or tab. You should then either:
Share the JSON data with the desired individual(s).
Share the data’s URL with another Edgecast team member.
You must establish an Edgecast session before attempting to load an Edgecast URL that points to a specific report or data. Attempting to load this type of URL without an active Edgecast session may load the Edgecast’s home page instead.
The time chart (aka line graph) graphs the current report’s data over time.
Key information:
By default, a single line plots all requests over time. Graph the top results for a specific field by clicking on the button that corresponds to that field. If the desired field is not listed, select it from within the Top Results section.
By default, a line graph includes up to the 10 most popular entries. Customize this limit through the Limit Results to Top option from the left-hand pane. This option also affects the maximum number of unique entries that may be listed within a Top Result chart.
Use the layout options to determine whether all data will be plotted on a single or multiple line charts.
Single Line Chart: By default, all data is plotted within a single chart with individual lines for each entry. Switch from multiple line charts to a single line chart by clicking the icon.
Click on the color-coded entries within the legend to hide or show them.
Multiple Line Charts: Generate a line graph for each entry by clicking the icon.
Hovering over the line graph will indicate the exact number of requests that were plotted for that time slot.
By default, Edge Insights plots data using an optimal time interval for the report’s time range. You may override this by switching the resolution from Auto to the desired time interval.
The report’s time range determines the set of available resolutions.
View the data used to plot this chart by clicking on the icon. Upon clicking this icon, Edgecast displays this data in JSON format within a new tab.
The top results charts displays the top results for 2 fields.
Key information:
By default, each chart may include up to the 10 most popular entries. Customize this limit through the Limit Results to Top option from the left-hand pane. This option also affects the maximum number of unique entries that may be graphed within the time chart.
The Top Results charts only include statistically significant entries. A gray slice called Rest... represents all remaining traffic.
Certain fields may generate a pie chart that solely consists of a Rest... slice. This behavior typically indicates either that there are many unique entries or that this field is not applicable to the majority of requests.
Example:
In the following illustration, the Client Postal Code pie chart returns a single slice called Rest.... The traffic represented by this pie chart is distributed throughout the world and therefore no single postal code was responsible for a statistically significant traffic segment. The Client Region Name pie chart, on the other hand, displays the top 10 regions. Those regions were responsible for majority of traffic included in this report.
Increasing the Limit Results to Top option to 30 provides visibility into additional POPs that were responsible for serving the majority of your traffic. Notice in the following illustration that the Rest... slice is now smaller since the pie chart now reports data for regions that were previously included by that slice.
You may switch a chart’s field by selecting a new one directly underneath the chart. The available set of fields vary by data source.
The fields selected in the Top Results section determine the available set of sources within the time chart.
Filter the entire report by clicking on a value within the chart.
Filters persist until they are manually removed from the Filters section in the left-hand pane. This allows you to quickly filter on multiple fields. Apply an additional filter by switching to another field and then clicking on the desired entry.
Optional. Click on = to toggle between filtering for requests that:
=: Match the specified value.
≠: Do not match the specified value.
Example:
Filter for requests that do not originate from a specific country by selecting the Country Name field, toggling this symbol to ≠, and then defining the name of the desired country.
Set the value through which the report will be filtered.
Advanced (Regular Expressions): If you are filtering by a field that reports a string value, then you may define a regular expression through the following syntax: regex:<REGULAR EXPRESSION>
Example:
Use this regular expression on the Country Name field to filter for requests that originated in United States, Canada, or Mexico:
Log data, which is reported within the Logs section, provides contextual information about a request that allows you to gain deeper behavioral insight into threat detection and CDN usage.
Key information:
Log entries are returned as paginated results. By default, we provide 10 log entries per page. You may increase this value up to 1,000 through the Logs per page option.
View a specific log entry by clicking on it.
View the current page’s log data by clicking on the icon. Upon clicking this icon, Edge Insights opens a new tab that contains a JSON object that represents the current page’s log data.
Edge Insights restricts log retrieval to 10,000 log entries. If the current report consists of more log entries, then you may only retrieve log data for 10,000 of the most recent requests. This limit solely applies to log retrieval. Your report’s time chart and Top Results charts display all available data without regard to this limit.

Matched On
Indicates a variable that identifies where the violation was found.
Matched Value
Indicates the value of the variable defined by the Matched On field. Standard security practices dictate that measures should be taken to prevent sensitive data (e.g., credit card information or passwords) from being passed as clear text from the client to your origin server. Another incentive for encrypting sensitive data is that it will be logged by our system when an alert is triggered as a result of this data. If sensitive data cannot be encrypted or obfuscated, then it is strongly recommended to contact our technical customer support to disable logging for the Matched Value field.
Operator Name
Indicates how the system interpreted the comparison between the Operator Parameter and the Matched Value fields. Common operators are:
BEGINSWITH: Begins with. Identifies a match due to a request element that started with the specified match value.
CONTAINS: Contains. Identifies a match due to a request element that contained the specified match value.
ENDSWITH: Ends with. Identifies a match due to a request element that ended with the specified match value.
STREQ: Exact match. Identifies a match due to a request element that was an exact match to the specified match value.
RX: Regex. Identifies a match due to a request element that satisfied the regular expression defined in the match value.
EQ: Value match. Identifies a match due to a request element that occurred the exact number of times defined in your custom rule.
IPMATCH: IP Address. Identifies a match due to the request’s IP address either being contained within an IP block or that was an exact match to an IP address defined in your custom rule.
Operator Parameter
Indicates the source or the value that was compared against the Matched Value field.
Pipeline Time
Indicates the number of seconds between when the request was received by our network and ingestion.
Platform
Returns cache.
POP
Identifies the POP that handled the client’s request by its three-letter abbreviation.
Profile ID

Indicates whether the request was screened as a result of a production or audit rule.
Receiving Host
Indicates the name of the server that inspected the request.
Referer
Indicates the request’s referrer as defined by the Referer request header.
Request Method
Indicates the request’s HTTP method.
Example:HTTP_METHOD_GET
Rule ID
Indicates the ID for the rule that the request violated. This field indicates that the rule met or exceeded the maximum anomaly score. Please refer to the Sub Event(s) section, which contains a sub event for each rule violated by a request, to find out why the request was flagged or blocked. Each sub event indicates the rule that was violated and the data used to identify the violation.
Rule Message
Provides a description of the rule that the request violated.
Syntax:Inbound Anomaly Score Exceeded (Total Score: 3, SQLi=0, XSS=0): Last Matched Message: Rule Message This term represents the message for the last rule that the request violated. This field indicates the request’s anomaly score and the last rule that it violated. Refer to the Sub Event(s) section, which contains a sub event for each rule violated by a request, to find out why the request was flagged or blocked. Each sub event indicates the rule that was violated and the data used to identify the violation.
Rule Tags
Indicates the tags associated with the rule that the request violated. These tags may be used to determine whether a rule, access control, or global setting was violated.
Naming convention:Rule Set/Category/Subcategory A category identifies whether the request violated a rule, an access control, or the delivery profile. The following sample values identify a policy: OWASP_CRS/PROTOCOL_VIOLATION/INVALID_HREQ and OWASP_CRS/WEB_ATTACK/SQL_INJECTION The following sample values identify a blacklist criterion: BLACKLIST/IP, BLACKLIST/COUNTRY, BLACKLIST/REFERRER, and BLACKLIST/URL The following sample value identifies a setting: OWASP_CRS/POLICY/SIZE_LIMIT
