Unified Communications Analytics 8.8.2 - Resource Kit

Initializing the client library

Initializing the client library

For a query to be run, you must create a connection to the OData client library. All examples include this information but the initialization step is highlighted here:

# ------------------------------------------------------------------------------------------------------------------------

# Initialize client library

$clientLibraryPath = "..\UC.Analytics.Insights.ResourceKit.ODataClientLibrary.dll"

$additionalLibraryPath = "..\Simple.OData.Client.Net40.dll"

try

{

Add-Type -Path $clientLibraryPath

Add-Type -Path $additionalLibraryPath

$serverUrl = "http://" + $analyticsServerName

$clientLibrary = New-Object UC.Analytics.Insights.ResourceKit.ODataClientLibrary.AnalyticsQueryClient($serverUrl)

}

catch

{

Write-Host "Encounter error : $Error[0].Message"

Exit

}

About the initialization step

For the initialization step, the following rules apply:

•
You enter the computer name but do not add the Analytics folder (as in the website)
•
Even if you have configured https for the website, the URL remains http.

The libraries required to run the PowerShell commands are located at:

%UCA_INSTALL_DIRECTORY%\Resource Kit

The initialization code assumes that the script files in the Samples subdirectory are open. If you move your script file, you must update the initialization code to explicitly point to the new location of the dependent library files.

 

Introducing the query structure

Once initialization is complete, the next step is to define the query. UC Analytics supports two types of queries:

•
aggregate queries
•
object queries.
About aggregate queries

Aggregate queries are queries that take a collection item and aggregate a metric over a given time period. For example, a query might show the number of messages sent by mailboxes over the last month.

•
The query output is in the form of a key/value pair. The key is the field defined in the grouping and the value is the given metric value.
•
Examples of aggregate queries are provided in the Samples directory in the file named AggregateQuerySamples.ps1.
•
Aggregate queries have the following syntax:
$result = $clientLibrary.`
For("{OBJECT_ITEM}").`
{TIME_CLAUSE}, `
{WHERE_CLAUSE}, `
{METRIC_VALUE}, `
{GROUPING_CLAUSE}, `
{TRENDING_CLAUSE}, `
QueryAsync().Result
About object queries

Object queries are queries that query the objects in database. For example, a query might show all mailboxes with the Display Name, Primary Email Address, and Custom Attribute 8.

•
The output of the queries are the selected attributes.
•
Examples of object queries are provided in the Samples directory in the file named ObjectQuerySamples.ps1.
•
Object queries have the following syntax:
$result = $clientLibrary.`
For("{OBJECT_ITEM}").`
{TIME_CLAUSE}, `
{WHERE_CLAUSE}, `
{SELECT_CLAUSE}, `
{ORDER_CLAUSE}, `
QueryAllAsync().Result

Each main clause is described later in this section.

Common query items

The query syntax is generic but order does matter. If you are familiar with C# LinQ, you might expect that you can change the order. However, for all OData library queries, you must enter the clauses in the order in which they are shown in the examples.

Also, the command structure shows a single command over multiple lines, which can be done in PowerShell. But to implement this option, you must include the backtick character `. Without the backtick character, your command will not work.

UC Analytics has a number of object items. To see a list of the items, run a PowerShell command called DataModelSamples.ps1 in the Samples folder. When you run the DataModelSamples.ps1 command, it lists all the available object types. Since the object types can change over time, it is important to run the command for your version of UC Analytics.

The following list shows the main object types in UC Analytics:

Many sections require an attribute name and there is a naming convention for these attributes. The names are identified in the output of DataModelSamples.ps1 command. You must specify the full attribute name if it transcends the associated objects.

Finding a full attribute name

The following walkthrough explains the process of finding the full attribute name for an object. Suppose that you want to filter all email messages by the sender’s department.

First, you run the DataModelSamples.ps1 to get a list of all the objects and their attributes.

To find the sender department for email messages
1
Since the query is on EmailMessage, find that object.
2
Look for the Sender field. It says the Sender field is a link to the EmailMessageParticipant item.
3
Find the EmailMessageParticipant item.
•
The EmailAddress item indicates the address of the object.
•
In the EmailAddress attribute, it says this field is a link to the MessagingAddressSnapshot
4
Find the MessagingAddressSnapshot item.
This provides a long list of attributes.
5
Since you want to query on an ActiveDirectory attribute, locate the Person attribute.
In the Person attribute, it says this field is a link to ActiveDirectoryObjectSnapshot.
6
Find the ActiveDirectoryObjectSnapshot item.
Now you have the list of Active Directory attributes for the Sender.
7
Find the Department attribute.

The final step is to follow the attributes to establish the full attribute name. You use a period to separate the items. The required items are bolded to make it easy to see.

In the example, the field would be: EmailAddress.Person.Department. You do not need to enter the first item as the query assumes that you will be starting from the Object Item.
