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.
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
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%' |
| !like | LHS doesn't contain a match for RHS | 'abc' !like '_d_' |
| 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 |

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 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.
