With the CardioLog API you can:


CardioLog Client-Side API

The CardioLog tracking agent allows for a client-side API to send custom events, and easily monitor button and banner clicks, video plays, or interactions with other UI components. On any monitored page, you can call the following JavaScript functions:

The SendEvent JavaScript Function

This function allows you to send events via the client agent. The Agent uses AJAX (Asynchronous JavaScript And XML) to send the event to the server, and will not affect the user interaction with the page in any way.

Code sample for sending a page view event:

The SendEvent function accepts the following parameters:

Note: when calling the "SendEvent" function within a different frame from where it is defined, make sure to reference the frame object containing it. For example, by using parent.document.__Page.SendEvent()

Monitoring Banner Clicks

You can monitor clicks on UI elements such as banners, buttons, navigation menu entries, links, etc. In order to capture a click on a banner that links to an external site, make a call to the CardioLog SendEvent function before redirecting the user to the external destination page. IF the banner was implemented with simple HTML, you can insert this code:

<a href="http://www.google.comonclick="document.__Page.SendEvent('Visit', 'Banners > My Links > externalsite.com');"><img src="google_logo.gif"></a>

In our example, when a user clicks on the banner CardioLog will send an event of type "Visit" to the server, specifying which banner has been clicked by the user before redirecting to "externalsite" (ie., "Banners > My Links> externalsite.com"). We recommend defining a unique prefix for each group of UI components that will be displayed in reports (in this case, "Banners") .

How many times were my banners clicked? To see how many times your banners were clicked, use the Events report (chart or table), and select "Banners" in the Website Item field.

Who clicked on my banners? To see who clicked on your banners, use the Visitors by Events report (chart or table), and select "Banners" in the Website Item URL field.

Please note that CardioLog automatically tracks outbound links from SharePoint sites to external destinations. To see how many times your links were clicked, use the External Destinations report.

The SetReferrer JavaScript Function

When users navigate internal links, you can monitor both the referring navigation component such as banners or menu items, along with the referring page. The SetReferrer function allows you to set custom page referrer details that are sent to the CardioLog server via following events (using SendEvent).

Code Sample:

<a href="http://mysite/rnd/index.aspxonclick="document.__Page.SetReferrer('Banners > MySite > Research and Development');"><img src="rnd.gif"></a>

 The SetReferrer function accepts the following parameters:

Monitoring UI Referrers

In order to capture the referring UI component before redirecting the user, make a call to the CardioLog SetReferrer function. Assuming the banner was implemented with simple HTML, this is a code example:

<a href="http://mysite/rnd/index.aspxonclick="document.__Page.SetReferrer('Banners > MySite > Research and Development');"><img src="rnd.gif"></a>

How many visitors accessed my page through a UI referrer? To see how many visitors arrived on your page through your UI referrer, use the Internal Traffic Sources report, and select the page in the Website Item URL field.

The SendGoal JavaScript Function

This function allows for sending JavaScript based goals via the client agent. The Agent uses Ajax (Asynchronous JavaScript and XML) to send the goal event to the server and will not affect the user interaction with the page in any way.

Code Sample:

 The SendGoal function accepts the following parameter:

Note: Goals are created in CardioLog > Administration > Goals. See "how to create a goal". After creating the goal, the Goal ID can be found in the tab_goals table (column - id) in the CardioLog database.  

Monitoring JavaScript-Based Goals

In order to capture a JavaScript based goal, such as signing up to a newsletter, define the goal in CardioLog > Administration (See "how to create a goal"), and make a call to the CardioLog SendGoal function.

Assuming the signup button was implemented with simple HTML:

<input type="button" value="Signup to Newsletter" onclick="document.__Page.SendGoal(1);" />

Goal Reports 

To see reports about your goals, use the Goals reports, and select the goal in the Visitor Segments > Goal field.


Monitoring Internal E-Mail Campaigns using the __referrer Parameter

The CardioLog Client-Side API supports capturing external referrers. You can use the _referrer parameter whenever you publish a link to your monitored environment and you wish to track the source of the referring page (e.g. email).

For example, if you have included an internal link in a promotional email add the __referrer parameter to be able to track the number of visits this link produced:

Define a unique referrer name that will be displayed in reports, such as __referrer=email_promotion_12_Dec_2008


How many visitors arrived on my page through my email campaign?

To see how many visitors arrived on your page through your email campaign, use the Navigation > Internal Traffic Sources report (either chart or table), and select the page in the Website Item URL field.

CardioLog Server-Side API

By Using the CardioLog Server-Side API - CardioLogAPI/Events.asmx web service and the SendEvent method - you can send viewduration and search events, as well as custom events, and track the URL of the referrer page.

The SendEvent Method

The SendEvent method in the CardioLogAPI/Events.asmx web service accepts the following parameters:

After the event is sent, the web service XML response will include the event identifier for future use, which you can later use to send events related to this event.




<status id='0'>OK</status>

<event id='211022'/>



 In case of an error, the XML response will include the error description:




<status id='-1'>Invalid Path</status>



Event Types

The SendEvent method supports the following event types:

  1. View - single page viewed or element clicked

To set the page referrer, use the following optional parameters for tracking the source of the page:

Referrer pages can be retrieved in CardioLog with the "Navigation" visual controls.

  1. Duration -  time spent on a page or element (in seconds).
  2. Search -

Search events can be viewed in CardioLog with the "Onsite Searches" visual control. The popular search terms are displayed in the "Onsite Search Phrases" visual control.

  1. Search Result Click -

Creating Custom Event Types

You can create custom event types and  build custom reports using the CardioLog SDK. The custom event types can be used in the SendEvent function (in both Client-Side and Server-Side APIs).

For example, if your website is a sales site and you wish to track each sale, and then create a report on the number of items sold, you can create a custom event type in CardioLog named "Item-Sold":

1. Add the custom event type to the CardioLog database by executing the following query against the CardioLog database:

INSERT INTO tab_event_type(id,description)
VALUES(100, 'Item-Sold')

Id - must be 100 or higher
description - event type title

2. Add the custom event type to the CardioLog tracking agent events array - edit the __eEvents array and add the custom event type in:

For MOSS 2007 only:
[CardioLog installation directory]\CardioLogAgent\MOSS2007_1.2.js

For SharePoint 2010 only:
[CardioLog installation directory]\CardioLogAgent\SP2010_1.2.js

For SharePoint 2013 only:
[CardioLog installation directory]\CardioLogAgent\SP2013_1.2.js

Note: If you have implemented the Tracking Agent using the "CardioLog Analytics" SharePoint Feature on your WFEs - edit the __eEvents array and add the custom event type in:

For MOSS 2007 only:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\LAYOUTS\CardioLogAgent\MOSS2007_1.2.js

For SharePoint 2010 only:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\CardioLogAgent\SP2010_1.2.js

For SharePoint 2013 only:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\CardioLogAgent\SP2013_1.2.js

__eEvents = {
Visit: { id: 0, name: "Visit" },
Leave: { id: 1, name: "Leave" },
Search: { id: 2, name: "Search" },
SearchResultItem: { id: 4, name: "SearchResultItem" },
SearchResultClick: { id: 5, name: "SearchResultClick" },
External: { id: 10, name: "External" },
Goal: { id: 20, name: "Goal" },
"Goal-Test": { id: 21, name: "Goal-Test" },
Test: { id: 22, name: "Test" },
Score: { id: 23, name: "Score" },
Ping: { id: 24, name: "Ping" },
Item-Sold: { id: 100, name: "Item-Sold" },
Unknown: { id: -1, name: "Unknown" }

3. Implement the call to the SendEvent function when an item is sold (using our Client-Side API or Server-Side API).

4. Create a custom report to display the number of items sold using the CardioLog SDK.

Non-Browser Apps

Since non-browser apps, such as mobile apps, don't contain HTML pages, developers simply determine when their apps should trigger page view requests. CardioLog Analytics then aggregates this data in reports to display the number of visits, unique visitors, session length, bounce rates, etc. This data gives insight into how users interact with the client app.

Developers can also track visitor actions that don't correspond directly to page views using other Event types. These user actions can include views of embedded videos, button clicks, downloads and more. App developers can then use this data to understand which features are most popular and inform decisions about which features should be promoted or prioritized for further development.


In order to track visitor actions for non-browser apps, developers must send usage event objects to the CardioLogAgent web application through HTTP POST requests in JSON format. The JSON string must be embedded in the request body. The POST response is provided in JSON format as well.

The Event Object

CardioLog Analytics usage event objects have the following properties:

In addition to event objects, the request body may include the following properties:

The JSON request format

The full JSON request format is as follows:

    "events": {
      "event": [
          "u": "http://www.intlock.com/",
          "X": "|referral|blog.intlock.com|/about/||",
          "et": 0,
          "RI": 564940
          "X": "1",
          "Y": "7",
          "et": 23,
          "RI": 0
    "browserType": "Apple-iPhone5C2/1001.525",
    "sessionid": "861529144.325047542",
    "un": "INTLOCK\\tomj"


The API URL for a SharePoint site is:

https://[SharePoint WFE]/_layouts/CardioLogAgent/tunnel.aspx?random= 895.3324414324015

Data Export API

With the Data Export API you can develop client applications to retreive data from the CardioLog reporting engine, and refine the results of the request using query parameters. It allows for more flexibility and customization than the CardioLog UI, giving you a great deal of freedom over how to display your reports, in terms of their design, filters and data content, and where the reports are displayed. It's also possible to brand your data with your organization's colors and logos to really take ownership of it.

The CardioLog reporting engine generates the report in XML format and as a chart image.

Use the Reports API Helper to generate a URL which can be embedded in a client application. When calling this URL the report will be generated based on the selected parameters.

  1. Browse: http://<cardiolog_server>:<port>/CardioLog/CLReport/ReportsAPIHelper.aspxYour browser may not support display of this image.
  1. Select a Report.
  2. Select the report parameters - Date RangeTime IntervalWebsite Item, Users and Groups
  3. Check Generate Chart Image to create an image and set its Width and Height (pixels).
  4. Click Get URL to generate the report URL
  5. Click Generate Report to generate the report.
  6. Click Show Advanced Options  and Get Report Preferences to modify report preferences.

The CardioLog Report XML Schema

The CardioLog report XML contains a preferences (prefs node) and a data section (data node).


The chart x-axis values are displayed in the categories node, while y-axis values are displayed in the dataset node (each chart series is represented by a dataset node).

1. How to add values to the chart image

In order to add values to the chart in the Data Export API, click on "Show Advanced Settings" and then "Get Report Preferences".
In the preferences XML, edit the <labels>true</labels> key and set the value to true. This will add values to the chart.

2. How to display the page views meter value

function getPageViews() {

// 1. Call the web service "http://cardiologservername:port/CardioLog/clreport/reportsapi.aspx" with the parameters "action=xml&controlId=3015&timeframe=77760000000000&urls=&usersAndGroups=&categoryId="

// 2. Create an XML file from the response and find the <data> node: selectSingleNode("//data").text;

// 3. Find the <value> node value with regex. Example:

var re = new RegExp("(^[^$]*<value>)([^<]*)(<\/value>[^$]*$)", "i");
if (response.match(re)) value = response.replace(re, "$2");
document.getElementById("pageviews").innerHTML = "This Year this site was viewed " + value + " times!";

window.onload = function () {


<div id ="pageviews" class="sample"> </div>
