View Software Changes on All Devices with REST API (Installed Software Change Log) (version 1.0)

Use INSTALLED_SOFTWARE_CHANGE_LOG to check and analyze the installed software related changes on each Windows physical monitored device, along with its version and deployment date. It includes all software deployed on the device but does NOT include Universal Windows Platform (UWP) applications (learn more).

For example, when several employees have a similar complaint of performance degradation, you can see if all of them modified the same software approximately at the same time. You can also get a list of uninstalled security updates across different devices.

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 an Aternity REST API, enter the base URL from User icon > REST API Access, followed by the name of the API: <base_url>/API_NAME into a browser, Excel or PowerBI (learn more). The <base_URL> is configured in the Aternity REST API Server as the external_url (learn more):

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


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

To see all the devices that removed a specific OS update, such as Security Update KB2966828, enter ...INSTALLED_SOFTWARE_CHANGE_LOG?$select=DEVICE_NAME&$filter=INSTALLED_SW_NAME eq 'Security Update KB2966828' and INSTALLED_SW_CHANGE_TYPE eq 'Uninstalled'.

To return a list of all changes in the organization software inventory during week 40 of 2018, use: .../INSTALLED_SOFTWARE_CHANGE_LOG?$filter=CALENDAR_WEEK eq '2018 Week 40'.

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?$filter=(USERNAME eq ''), or several parameter-value pairs each separated by an ampersand (&), like .../API_NAME?$format=xml&$top=5.

Parameter Description

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


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 with operators: and, or, eq (equals) gt (greater than), ge (greater than or equal), lt (less than), le (less than or equal), ge (greater than or equal to), ne (not equal to), le (less than or equal to), not and contains. 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'))


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


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


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

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

$search is NOT supported.

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


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


You can access data using this API (retention) going back up to 92 days, meaning you will see the changes that occurred in the last 90 days for all devices which reported to Aternity during that time.

If you do not add a relative_time filter, by default it returns data for the past 7 days.

The API returns two types of columns: Attributes (or dimensions) which are the properties of an entry, and Measurements which are the dynamic measured values. A single API row can display either a single measurement, or a weighted average of several entries grouped together. If you use $select to display several attributes, and all those attributes are identical, it groups them into a single entry.
