View Requests of Licenses in REST API (License Events)

Use LICENSE_EVENTS to view a device's most recent request to Aternity for a monitoring license, and if rejected, it displays the reason. Aternity automatically allocates license units whenever a device requests to report its performance. By default, Aternity reserves your manually allocated licenses, then automatically grants requests from any device type until it reaches the total licenses allowed. You can also limit the number of licenses for each type of device. For example, if you purchase 1000 license units, you can set a limit of up to 300 B2E mobile devices.

For example, you can check whether a specific device does not appear in the dashboards due to insufficient licenses, and then purchase more licenses if required.

Manually allocate a license, or allow Aternity to automatically allocate from the available licenses

Each entry from LICENSE_EVENTS returns a the last request from this device for a license, the type of license, and whether Aternity accepted or rejected the request with the reason.

You can view this data and set limits for license units inside Aternity, and there you can also view these licensing events which list those granted or rejected (learn more).

Before You Begin

To send a REST API query in Excel, PowerBI or a browser, enter the URL of the REST API, your Aternity username (must have the OData REST API role) and its password. You can find this by selecting User icon > REST API Access. SSO users must generate (once) and use a special password, as Aternity's REST API does not authenticate with your enterprise's identity provider. For LDAP users, enter the domain name, then a backslash ('\'), then your network username and password. For example domain_name\jsmith

To view Aternity REST API, enter the base URL from Aternity > User icon > REST API Access, followed by the name of the API into a browser, Excel or PowerBI (learn more). For VIEWING, use <base_url>/latest/API_NAME; for INTEGRATIONS, use <base_url>/<version number>/API_NAME (for example, <base_url>/v1/API_NAME, or <base_url>/v1.0/API_NAME, or <base_url>/v2/API_NAME, or <base_url>/v2.0/API_NAME).

The <base_URL> is configured in the Aternity REST API Server as the external_url (learn more):

Tip

Wherever possible, use $select and $filter to narrow your query, to avoid receiving an error like Returned data is too large. Learn more.

Examples

To access this API from a browser, Excel or Power BI (learn more), enter <base_url>/latest/LICENSE_EVENTS or <base_url>/v2/LICENSE_EVENTS

If a device does not appear in Aternity's dashboards, you can check if Aternity granted a license to that device:

.../LICENSE_EVENTS?$select=license_event,license_owner,license_event_reason&$filter=license_owner eq 'hostname'

Supported Parameters

You can view the data by entering the URL into Excel, into a browser, or into or any OData compatible application such as Power BI.

You can add parameters to the URL to filter the returned data, by adding a question mark (?) followed by a parameter and value, such as .../API_NAME?$filter=(USERNAME eq 'jsmith@company.com'), or several parameter-value pairs each separated by an ampersand (&), like .../API_NAME?$format=xml&$top=5.

Query Options Description
$select=

Use $select to return only specific columns (attributes), to make queries more efficient: ...API_NAME?$select=COL1,COL2,COL3
$format=

Use $format to force the returned data to be either in XML or JSON format. This is only useful for testing the raw data in a web browser. For example: .../API_NAME?$format=xml
$orderby=

Use $orderby to sort the returned data according to the value you choose. For example, .../API_NAME?$orderby=LOCATION

Also, use $orderby to sort the returned data in ascending or descending order. For example, .../API_NAME?$orderby=Activity_Response_Time desc or .../API_NAME?$orderby=Activity_Response_Time asc

The default is ascending.
$top=

Use $top (lower case only) when you are initially testing the response of the API by returning the first few entries.

Also, use $top to filter the returned data and to return only the first N entries.

For example, to return the first five entries (not sorted), use: ...API_NAME?$top=5
$filter=

Use $filter to insert conditions that narrow down the data, to return only entries where those conditions are true..

To limit the timeframe of a query, add $filter=relative_time() like, .../API_NAME?$filter=relative_time(last_x_hours) or (last_x_days). Learn more.

Create conditions for filtering with any of the following operators:

Query Operators Description
eq

Equal to

For example, COL4 eq 'val4'
ne

Not equal to

For example, COL4 ne 'val4'
gt

Greater than

For example, COL4 gt 'val4'
ge

Greater than or equal

For example, COL4 ge 'val4'
lt

Less than

For example, COL4 lt 'val4'
le

Less than or equal

For example, COL4 le 'val4'
and

Logical and

For example, COL1 eq 'value1' and COL2 ne 'value2'
or

Logical or

For example, COL1 eq 'value1' or COL2 ne 'value2'
not

Logical negation

Create conditions for filtering with any of the following functions:

Query Functions Description
startswith

For example, $filter=startswith(account_name,'Aternity')
endswith

For example, $filter=endswith(account_name,'Aternity')
contains

$filter=contains(COL5,'val5')

For example, $filter=contains(account_name,'Aternity')
in()

Instead of using AND, OR:

$filter=device_name eq ‘adam_covert_wks’ or device_name eq ‘adam_covert_vdi’ or device_name eq ‘adam_covert_tablet’

You can now use:

$filter=in(device_name,‘adam_covert_wks’,‘adam_covert_vdi’,‘adam_covert_tablet’)

Read carefully specific instructions for writing this function:

  • In must be followed directly by the opening parenthesis (no space allowed)

  • The first parameter is the field name (case insensitive)

  • The function requires at least two parameters, the field name and at least one field value

  • The rest of the parameters are the optional values that the field can have (i.e. the values we want to filter in) also case insensitive

  • Values are separated by comma and no spaces allowed

  • The maximum number of values in all clauses is 1,500 (e.g. It is possible to have 1 In() with 1500 values, or 2 In() clauses with 750 each).

  • The last value must be followed by the closing parenthesis (no space allowed)

  • In() can be combined with any other filter using AND or OR

  • There can be more than one in() function in a filter. For example, $filter=in(location,’loc1’,’loc2’) or in(subnet,’sub1’sub2’). Another example, $filter=in(location,’loc1’,’loc2’) and in(subnet,’sub1’sub2’)
relative_time(last_x_hours)

Limit the timeframe of a query.

If no relative_time filter is used to set a specific timeframe, Aternity will return the default last N days worth of data. Default values vary for different APIs. Learn here about specific REST API.

Use operators with parentheses to group conditions logically: .../API_NAME?$filter=(COLUMN1 eq 'value1' or COL2 neq 'val2') and (COL3 gt number) and not (COL4 eq 'val4' or contains(COL5,'val5'))
$search is NOT supported.

Do not use $search in Aternity's REST APIs.

Output

Each entry from LICENSE_EVENTS returns a the last request from this device for a license, the type of license, and whether Aternity accepted or rejected the request with the reason.
