When you run a query, the Performance Analysis page displays the following information:
- Query Summary section with the main information about the query and its progress
- Results of the query aggregated according to various metrics
Tip
While a query is in progress, you can click Display Sample Data on the shortcut menu. A secondary browser window or tab displays sample data in HTML format, as shown in the following figure, giving you an idea of the results.
Sample query data
Query summary
The following figure shows an example of the Query Summary section for a query in progress:
Query in progress
The Query Summary section provides the following information:
- Filter used to run a query, consisting of the record type, the sector of the monitored traffic (Watchpoint name), and the time range
Example: [Page] query on [all traffic] over [Last 7 days] - In Progress — Percentage of data that the system has searched, compared to the total amount of data
- Pages Scanned — Number of pages or objects that the system has scanned
- Pages Found — Number of detected pages or objects that meet the query criteria
- Sessions — Number of user sessions that contain the detected pages or objects
- Progress bar — Amount of data that the system has searched, compared to the total quantity of found records (corresponds to the In progress percentage)
As shown in the following figure, you can view additional information about the query by clicking the Details button. Click Details again to hide the details.
Query Summary section with details
This section shows the following details about the query:
- Issued on — Date and time of query creation
- Time Range — Time interval for which the query is searching records
- Watchpoint — Name of the traffic segment that the query scans (if applicable)
- Filter — Filter expression used to search through the data (if applicable)
Aggregated results
You use query parameters to narrow down the number of detected sessions. Excluding the latency metrics, parameters display only the most frequent values. All the remaining values are aggregated into others. The following sections contain the aggregated results for the query:
The following figure is a sample of the Application pane:
Application pane
The Application pane displays the following information about the application parameters:
Metric or attribute | Description |
|---|---|
Page Name | Unique page names that meet the query criteria and are shown as a percentage of the total page count |
E2E Latency (ms) | End-to-end latency of the entire object or page, including HTTP redirects, in milliseconds. Akamai download time is sometimes used to calculate this metric. |
Host Latency (ms) | Time for the server to process the user's request and to generate a response, in milliseconds |
Network Latency (ms) | Time for the object or page data to be transferred across intervening networks, in milliseconds |
SSL Latency (ms) | Time for the web system to negotiate SSL encryption for this object or page, in milliseconds (not applicable if the page was not encrypted) |
Redirect Latency (ms) | Time spent redirecting the user to this page, in milliseconds |
Page Render Time (ms) | The time to render all the content on a page (including objects not coming from its origin), in milliseconds |
Size (b) | Size of this object or page (request and response), in bytes |
Object Count | Number of content hits on a certain page. This parameter applies for page queries only and is not displayed for object queries. |
Error Condition | Error detection rule (error severity) created on the data provider that detects an error when a given event occurs in the web traffic |
Info Condition | Error detection rule (informational severity) created on the data provider that detects an error when a given event occurs in the web traffic |
The following figure is a sample of the User pane:
User pane
The User pane displays the following information about the user parameters:
Attribute | Description |
|---|---|
Browser | Name of the browser that the user is using, as it is set up in the data provider |
City | City the user is using as derived from the IP geolocation |
URI | Uniform resource identifier (URI) of the object that is requested. It is the full path and resource obtained from the URL starting from the first / character. |
Client IP | IP address of the client that generated the request |
The following figure is an example of the Infrastructure pane:
Infrastructure pane
The Infrastructure pane displays the following information about the infrastructure parameters:
Attribute | Description |
|---|---|
Host | Value of the host as it is displayed in the HTTP header |
Server ID | Name or identifier of the server or network infrastructure component that serviced the request |
Server IP | IP address of the server that responded to the request |
TCP OOO | Number of out-of-order TCP segments in the transmission. This is usually an indication of route flapping or poor link load balancing. |
TCP RTT (ms) | Average TCP round-trip time (RTT) of all objects or pages between the client and the server, in milliseconds |
TCP RTX | Number of TCP segments retransmitted. A high number of retransmissions might indicate traffic shaping or packet loss. |
