Performance Events

Event Properties Tab

General Properties

Event Class: Client Side Performance Event (for page load event) or Client Side Ajax Performance Event (for Single Asynchronous AJAX Call event) or Client Side Action Performance Event (for JavaScript scope execution, like Control.OnClick() handler, etc.)
Aspect: Performance
Component: Unknown
Source: The name of the application that received the client request. This name is also a link which will open the Application Resource Utilization window for the named application.
Event Date: The date/time stamp for when an event occurred according to the Server's clock.
Status: Indicates that someone has applied a rule to a set of events via the 'Rules Management wizard..', in order to properly triage events. This value may be 'New', 'Reviewed', 'Behavior by Design' or 'Deleted'
Build: N/A
Computer: The name or IP address of the computer that processed the request. This name is also a link which will open the Computers Resource Utilization window for the named computer.

Call Type

The call type will display a Page URL, AJAX call or JavaScript call. For each call, any or all of the following will be displayed:

queryString: The portion of the URL from the "?" to the end of the request
sessionID: The unique identifier used to recognize a series of related message exchanges
urlReferer: The URL of the previous webpage from which a link was followed or an AJAX call was made
MVC Controller: Applicable for MVC applications only
MVC Action: Applicable for MVC applications only

If this symbol appears to the right of the call type, then clicking on it will open a window showing links to the corresponding event. No chain link is displayed if there are no corresponding events. if there are several single chain events, the single 'Chaining Wizard' opens. Please see Your Management SystemPerformance Event Details in the "Intercept Studio User Manual" for more information.

Performance Metrics

Page Load Time / Execution Time

The left side of the Performance Metrics section displays the Page Load Time data for events where the Event class = 'Client Side Performance Event', and Execution Time data for events where the Event class = 'Client Side Action Performance Event'. The following fields appear for Page Load Time and or Execution Time:

Total Time: The duration from the initial page request until the window.onload() event handler completes execution (see diagram below).
Graph

When the Event class = 'Client Side Performance Event', the 'Page Load Time' graph displays:

When the Event class = 'Client Side Ajax Performance Event' (for single, asynchronous AJAX calls), the 'Execution Time' graph displays:

When the Event class = 'Client Side Action Performance Event' (for actions such as OnClick()), the 'Execution Time' graph displays:

Duration

Threshold:

	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	Time To Last Byte. This is the time between sending the asynchronous AJAX request and when the ajaxRequestObject.readyState property is marked as 'complete'.
	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	N/A

DOM Ready: This field is available when the event class = Client Side Performance Event

	Client Side Performance Event	This time indicates that all of the HTML is loaded even if the peripheral loading has not completed. It is the duration between the page request and the DomIsLoaded timestamp.
	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	N/A
	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	N/A

Page Ready:

	Client Side Performance Event	This time indicates when the page content and all linked flat files have been loaded. It is the equivalent of the total event time, which is the duration from the initial page request until the window.onload event handler completes execution.
	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	N/A
	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	N/A

Network Request:

	Client Side Performance Event	This is the time between the unload of previous page and the time to first byte of current page, minus the server response time.
	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	This is the time between the Asynchronous AJAX Request being sent and the return of the 1st byte of AJAX response, minus the server response time.
	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	This time reflects the total network request time for all synchronous AJAX calls while the user action (e.g. OnClick() handler) executes.

Server Response Time:

	Client Side Performance Event	This is the time from the beginning of the HTTP Request processing until writing the output response data begins. When relevant, this field is broken down to display the time spent on each page redirect and/or related server side performance events. The remaining time displayed in the breakdown (that is not for redirects) is the server processing time of the final page in the chain of redirects. Redirects are displayed in the graph as dark bars within the Server Processing area. Tooltips are provided to display the URL of the redirect or source name of the server side event. Server side performance event times act as links to actual events.
	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	This is the time from the beginning of the HTTP Request processing until writing the output response data begins. AJAX events do not have a breakdown for server response time.
	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	This time reflects the total server time for all synchronous AJAX calls while the user action (e.g. OnClick() handler) executes.

	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	N/A

Peripheral Loading:

	Client Side Performance Event	The time for the browser to load all linked files (images, CSS, HTC files etc.) It is the time duration between the DomIsLoaded timestamp and the beginning of the window.onload() event handler.
	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	N/A
	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	N/A

	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	This time reflects the total Network Response time for all synchronous AJAX calls while the user action (e.g. OnClick() handler) executes.

JavaScript:

	Client Side Performance Event	N/A
	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	The time spent processing JavaScript code when the ajaxRequestObject.onreadystatechange() event handler completes execution.
	Client Side Action Performance Event(for user subscriptions on control events, e.g. OnClick())	The time spent processing any JavaScript code subscribed to by a monitored control event, minus the durations of all Server Response times and network Request/Response durations related to nested synchronous AJAX calls that took place while control event fired. In other words, if synchronous AJAX calls are inner functions then they are not included in the reported execution time.

window.onload:

	Client Side Performance Event	The time spent processing any code inside the window.onload() function
	Client Side AJAX Performance Event(for single, asynchronous AJAX calls)	N/A

Page Content Size / AJAX Data Size

Total Size: The number of bytes loaded in the page or AJAX data.
Network Latency: This value is calculated by pinging the server (in ms).
Channel Quality: This value is based on the network latency. The value may be:.

Excellent: 0 to 128 ms

Good: 128 - 500 ms

average : > 500 ms.

Graph: The graph allows users to determine at a glance which file type makes up the bulk of the page size

For Client Side Performance Events (under 'Page Content Size') the graph will display any or all of the following:

HTML
Images
Scripts
CSS
HTC
AJAX Response(s): Total length of responses from AJAX calls that take place on page loading, where the page loading interval = the time between the first page byte (at the start of 'Dom Loading') until 'window.onload()' completes.

For Client Side Action Performance Events (under 'AJAX Size') the graph will display one or both of the following:

Request: Total Length of AJAX Requests
Response: Total Length of AJAX Responses

Heaviest Resources

The heaviest resource is the call that exceeded it's threshold more than other resources. The call may be any of the following:

NETWORK REQUEST: Client IP network [e.g. 'Network Request : 172.1.1.0]
SERVER RESPONSE TIME: short URL [e.g. Server Response Time : /Duwamish7/Default.aspx]
NETWORK RESPONSE: Client IP network [e.g. 'Network Response : 172.1.1.0] for Client Side AJAX Performance events and Client Side Action Performance events only
DOM LOADING: short URL [e.g. DOM Loading : /Duwamish7/Default.aspx] for Client Side Performance (page load) events only

JAVASCRIPT: function name for Client Side AJAX Performance events and Client Side Action Performance events only
WINDOW.ONLOAD(): short URL [e.g. window.onload : /Duwamish7/Default.aspx] for Client Side Performance (page load) events only

Control

The control section applies to action performance events such as OnClick events.

The following control properties are collected for elements where the tag is not IMG

Tag Name: name of tag (e.g. INPUT or DIV)
ID: value of attribute "ID"
Name: value of attribute "Name"
Type: value of attribute "Type", e.g. "submit" for tag name of "INPUT" for OnClick action events
Value: value of attribute "Value”.

The following control properties are collected for element where the tag is IMG

Tag Name: IMG
ID: value of attribute "ID"
Name: value of attribute "Name"
Type: value of attribute "Type"
Source URL: URL of the image
Value: small copy of the image with actual dimensions (width x height) and presentation ratio proportions specified..

JavaScript

The JavaScript area provide information about the JavaScript method and parameters executed in during client side action events, such as OnClick. This are applies to client side performance events. If there is no subscription, the value field will have a value of "n/a”.

The following information appears under JavaScript:

Name: The name of the action event, e.g. window.onload, or [SUBMIT: Login >>].OnClick()
Value: The source code for the event handler, e.g. function anonymous() { LoginPage_OnLoad(); }, or WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("LoginButton", "", true, "", "", false, false))

AJAX Calls Information

AJAX Calls Information is reported for events of type "Client Side Action Performance Event" (OnClick, OnMouseDown, etc.) and "Client Side Performance Events" (for Page Load). Please note that "AJAX Call" and "AJAX Calls" report different information

If any nested asynchronous AJAX call has not yet completed, Client Side Action Performance event and Client Side Performance events will display the call time measured up until the event was reported. The time will be displayed, for example, as "≥ 100 ms (Not Completed Yet)”.

The display will include:

The total number of synchronous calls
The total number of asynchronous calls
The total execution time for all synchronous calls combined
A list of each synchronous call, each of which expands to show the same Network Request and Network Response details as for the single, asynchronous calls
A list of each asynchronous call, each of which expands to show the same Network Request and Network Response details as for the single, asynchronous calls

For each AJAX call, the following information is displayed:

Network Request

Requested URL

Request Method (POST, GET, etc.)

Request Length (bytes)

Server Response Time (ms)

Post Data (1st two kilobytes of post data): the value for POST requests only, will always be N/A for GET requests

Server Response Time
Network Response

Result Code

Content Type

Compressed: a flag indicating whether the response was compressed by the Application Server or not

Response Length (bytes)

Response Text (1st two kilobytes of response content)

Internal Execution (for asynchronous AJAX calls only )

JavaScript

AJAX Call Information

AJAX Call Information is reported for events of type "Client Side AJAX Performance Event". Please note that "AJAX Call" and "AJAX Calls" report different information

The following information is displayed for single asynchronous AJAX calls:

Network Request

Requested URL

Request Method (POST, GET, etc.)

Request Length (bytes)

Server Response Time (ms)

Post Data (1st two kilobytes of post data)

Server Response Time
Network Response

Result Code

Content Type

Compressed

Response Length (bytes)

Response Text (1st two kilobytes of response content)

Internal Execution

JavaScript

Content Information

Because the content size cannot always be collected, Intercept uX can try to make an AJAX call for server to get the file one more time and to get its size. This additional call may seriously increase traffic to the server, so it is configurable through the 'Collect Content Size Information' flag which enables or disables the AJAX calls. When the flag is on, uX makes the AJAX call only if target file URL is located in the same domain and has the same port as monitored web application (because cross-domain requests are restricted for AJAX calls). When the flag is off sizes are only displayed for some type of the content, otherwise all sizes are displayed (except for some special cases).

Please see ConfigurationIntercept uX Management ConsolePerformance Settings Properties for a detailed description about content size collection.

The following sections appear under 'Content Information', providing lists of content items under the appropriate headers as well as a total for the number of bytes in each section:

Page Parameters

The Page parameters section displays the total size (in bytes) of all page Html and the size (in bytes) of the ViewState hidden field.

Images

Note that images are separated by those which were loaded during 'Dom Loading' and those which were loaded during 'Peripheral Loading'.

Source File: By mousing-over the image name, a tooltip will provide the path to the image and the image will become visible in a preview window. The file name also acts as a link to the file.

File Size (bytes)

Loading Scope (ms): The loading scope provides a visual indicator or the interval during which the image loaded and the elapsed time in ms between TTFB and load completion. The color of the bars in the chart show whether loading started during 'Dom Loading' or 'Peripheral Loading' There are some special circumstances to note for the loading scope:

When neither a start or end time for image loading can be determined, a gray bar is displayed with n/a for the column values
When only the start time can be determined for an image (and therefore no duration can be calculated), only the colored square within which the startLoading timestamp resides will be displayed
When only the end time can be determined for an image (and therefore no duration can be calculated), it is assumed that the image loading started before DOM Ready was detected, so the DOM Loading square is displayed as the first square

Scripts

Source File: By mousing-over the image name, a tooltip will provide the path to the file. The file name also acts as a link to the file.

File Size (bytes)

Cascading Style Sheets

Source File: By mousing-over the image name, a tooltip will provide the path to the file. The file name also acts as a link to the file.

File Size (bytes)

HTC Behaviors

Source File: By mousing-over the image name, a tooltip will provide the path to the file. The file name also acts as a link to the file.

File Size (bytes)

Browser Capabilities

The following information appears under Browser Capabilities:

Browser Type: The short alias of the user's browser, including the type and version (e.g. IE7, MOZILLA FIREFOX). This value is always collected.
User Agent: This field holds extended information about the main properties of the user’s environment, such as installed FW versions, OS version, browser type and version. For example, Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 1.0.3705). This information is always collected.

End User Information

The following information appears under End User Information:

Tenant Name: The tenant name is the string that identifies the business context for each web application request. See Advanced Configuration for information about configuring tenant information collection.
User Host Address: Information from the string sent by the browser to the web server indicating the browser version. This value may either display the actual client IP or the address of an intermediary software component, such as a firewall. To display the actual client IP, you must configure the request header on the 'Client IP' tab in the Configuration Utility.
User Name: The user name is only displayed when the user has authenticated.

Collection Notes

Collection notes provide additional data about any restrictions that apply to the event. If restrictions are in effect, the Collection Notes area will be open and visible when the event details are opened.

Similar Events Tab

This tab may be used to find similar events that are occurring in your system. You may filter for identical events or by events which have the same heaviest resource. Please see "Your Management System""Performance Event Details" in the "Intercept Studio User Manual" for more information.

Session Events Tab

The 'Session Events Tab' links together all performance events for client calls, server side ASP.NET and server side AJAX calls based on the session ID (or User Name or User Address, depending on the criteria selected). The selected time spans the timestamp for the current event, e.g. if a 2 minute period is selected and the current event occurred at 9:00:00 AM, then the time period displayed would be for 8:59:00 AM through 9:01:00 AM. Any events with the same session ID (or User Name or User Address, depending on the selected 'Similar by' value) that occurred during that time frame will be displayed.

General Properties

Period: 1 minute, 2 minutes, 3 minutes, 5 minutes, 30 minutes, 1 hour.
Similar by: Session ID, User Name, User Address.
Number of Events: The number of session events for the selected time period
First Event Date: The 'First Event Date' field displays the date/time stamp for when the first event in the selected time period occurred.
Last Event Date: The 'Last Event' field displays the date/time stamp for when the last (most recent) event in the selected time period occurred.

Diagram View

The diagram view displays a horizontal bar chart of the related events. The top horizontal axis shows the selected period in either minutes or seconds. For example, a 2 minute time period would be displayed on the top axis as:

-60

-40

-20

The bottom horizontal axis displays timestamps for the beginning, middle and end of the intervals displayed on the top horizontal axis. Therefore, for the example above, the bottom axis might display:

09:30:56

9:31:56

9:32:56

Each bar (row) in the chart displays the duration of the event, and are color coded to indicate whether the event is a client call,, ASP.NET server side event or AJAX server side event. The end of each bar displays the source and type of each event, and each acts as a link to the event details window. The event text in orange is for the current event.

Table View

The Table View display all of the same events as described above in the 'Diagram View', but in tabular format with the event ID, Description and event duration, event source, and timestamp.

Distributed Chains Tab

The Distributed Chains Tab provides a graphical display of performance issues as they occur across multiple tiers in a distributed transaction, including performance events from the client side. Two views are provided for viewing event chains: Single Transaction and Multi-transaction. Single transaction chains display how events from a single business transaction are interconnected. For any single business transaction, there is no guarantee that events will be generated from all tiers involved in the transaction, and therefore the chain may appear to be incomplete. Because of this, Intercept also provides a multi-transaction chain, that maps event averages gathered for a transaction across a defined time period. Please see "Your Management System""Performance Event Details" in the "Intercept Studio User Manual" for more information.

The Chain duration time must be greater than the server event duration (since the chain duration for a client event = network time + server time). In the event that no measurable network time has been recorded, no consolidation may take place and no chain will be displayed.
