Device query

Device query allows you to quickly gain on-demand information about the state of your devices. When you enter a query on a selected device, Device query runs a query in real time. The data returned can then be used to respond to security threats, troubleshoot the device, or make business decisions.

Prerequisites

To use Device query in your tenant, you must have a license that includes Microsoft Intune Advanced Analytics. Advanced Analytics features are available with:

  • The Intune Advanced Analytics Add-on
  • Microsoft Intune Suite

To use Device query on a device, the device must be enrolled in Endpoint Analytics. Learn how to enroll a device in Endpoint Analytics.

You cannot opt out of cloud notifications (WNS)

For a user to use Device query, you must assign the Managed Devices - Query permission to them.

To use Device query, devices must be Intune managed and corporate owned.

Supported platforms

Device query is currently only supported on devices running Windows 10 and later.

How to use Device query

To use Device query, navigate to Devices and select the device on which you want to use Device query. Select Device Query under the Monitor section.

The supported properties you can query are listed in the Properties section. To run a query, enter a Kusto Query Language (KQL) query, and select Run. Results are displayed in the Results tab area.

For more information on Kusto Query Language, see Learn more about Kusto Query Language.

Tip

You can now use Copilot in Intune (public preview) to generate KQL queries for device query using natural language requests. To learn more, go to Query with Copilot in device query.

Supported Operators 

Device query supports only a subset of the operators supported in the Kusto Query Language (KQL). The following operators are currently supported:

Table operators

Scalar operators

Aggregation functions

Scalar functions

Table operators

Table operators can be used filter, summarize, and transform data streams. Currently the following operators are supported:

Table operators Description
count Returns a table with a single record containing the number of records
distinct Produces a table with the distinct combination of the provided columns of the input table
join Merge the rows of two tables to form a new table by matching row for the same device
order by Sort the rows of the input table into order by one or more columns
project Select the columns to include, rename or drop, and insert new computed columns
take Return up to the specified number of rows
top Returns the first N records sorted by the specified columns
where Filters a table to the subset of rows that satisfy a predicate

Scalar operators

The following table summarizes operators:

Operators Description Example
== Equal 1 == 1, 'aBc' == 'AbC'
!= Not Equal 1 != 2, 'abc' != 'abcd'
< Less 1 < 2, 'abc' < 'DEF'
> Greater 2 > 1, 'xyz' > 'XYZ'
<= Less or Equal 1 <= 2, 'abc' <= 'abc'
>= Greater or Equal 2 >= 1, 'abc' >= 'ABC'
+ Add 2 + 1, now() + 1d
- Subtract 2 - 1, now() - 1h
* Multiply 2 * 2
/ Divide 2 / 1
% Modulo 2 % 1
like Left Hand Side (LHS) contains a match for Right Hand Side (RHS) 'abc' like '%B%'
contains RHS occurs as a subsequence of LHS 'abc' contains 'b'
!contains RHS doesn't occur in LHS 'team' !contains 'i'
startswith RHS is an initial subsequence of LHS 'team' startswith 'tea'
!startswith RHS isn't an initial subsequence of LHS 'abc' !startswith 'bc'
endswith RHS is a closing subsequence of LHS 'abc' endswith 'bc'
!endswith RHS isn't a closing subsequence of LHS 'abc' !endswith 'a'
and True if and only if RHS and LHS are true (1 == 1) and (2 == 2)
or True if and only if RHS or LHS is true (1 == 1) or (1 == 2)

Aggregation functions

Aggregation functions can be used with the summarize table operator to calculate summarized values. Currently the following aggregation functions are supported:

Function Description
avg() Returns the average of the values across the group
count() Returns a count of the records per summarization group
countif() Returns a count of rows for which Predicate evaluates to true
dcount() Returns the number of distinct values in the group
max() Returns the maximum value across the group
maxif() Starting in version 2107, you can use maxif with the summarize table operator.

Returns the maximum value across the group for which Predicate evaluates to true.
min() Returns the minimum value across the group
minif() Starting in version 2107, you can use minif with the summarize table operator.

Returns the minimum value across the group for which Predicate evaluates to true.
percentile() Returns an estimate for the specified nearest-rank percentile of the population defined by Expr
sum() Returns the sum of the values across the group
sumif() Returns a sum of Expr for which Predicate evaluates to true

Scalar functions

Scalar functions can be used in expressions. Currently the following scalar functions are supported:

Function Description
ago() Subtracts the given timespan from the current UTC clock time
bin() Rounds values down to many datetime multiple of a given bin size
case() Evaluates a list of predicates and returns the first result expression whose predicate is satisfied
datetime_add() Calculates a new datetime from a specified datepart multiplied by a specified amount, added to a specified datetime
datetime_diff() Calculates the difference between two date time values
iif() Evaluates the first argument and returns the value of either the second or third arguments depending on whether the predicate evaluated to true (second) or false (third)
indexof() Function reports the zero-based index of the first occurrence of a specified string within input string
isnotnull() Evaluates its sole argument and returns a Boolean value indicating if the argument evaluates to a non-null value
isnull() Evaluates its sole argument and returns a Boolean value indicating if the argument evaluates to a null value
now() Returns the current UTC clock time
strcat() Concatenates between 1 and 64 arguments
strlen() Returns the length, in characters, of the input string
substring() Extracts a substring from a source string starting from some index to the end of the string
tostring() Converts input to a string representation

Supported Properties

Device query supports the following entities. To learn more about what properties are supported for each entity, see Intune Data Platform Schema.

  • BiosInfo

  • Certificate

  • Cpu

  • DiskDrive

  • EncryptableVolume

  • FileInfo

  • LocalGroup

  • LocalUserAccount

  • OsVersion

  • Process

  • SystemEnclosure

  • SystemInfo

Known limitations

  • The result string of any query is limited to 128kb characters. If the result of your query is longer than 128kb characters, the result is truncated. An error message informs you about how many rows are truncated.

  • You can only send 15 queries a minute. If you run into a query limit exceeded error, wait for a minute and try again.

  • Query inputs have a length limit of 2048 characters. If you encounter a query too long error, then refine your query to have fewer characters and try again.

  • The now() scalar function doesn't support the offset parameter.

  • The !like operator is not supported.

  • The input window auto-recommends double quotes when only single quotes are supported on the following operators:

    • contains
    • !contains
    • startswith
    • !startswith
    • endswith
  • The WindowsRegistry entity fails to return the RegistryKey for root.

  • The WindowsRegistry entity fails to return 64-bit shared registry keys.

  • The WindowsRegistry entity fails to return binary ValueData.

  • If you’re querying devices that are running on Windows 10, they must be on a minimum quality version.

    • If running Windows 10 21H2, ensure that it's running version 10.0.19044.3393.

    • If running Windows 10 22H2, ensure that it's running version 10.0.19045.3393.

  • If there are multiple network cards available on the machine, then only the first configured domain is returned.

  • If TPM 2.0 is present on the device, then activated and enabled is always returned as TRUE.

  • If a file is currently in use on the machine, then FileInfo queries returns an error.

  • If the end user has admin access to the device, they might be able to change client-based information that show up in the query results. For example, OS version and registry.
