CMPivot for real-time data in Configuration Manager
Applies to: System Center Configuration Manager (Current Branch)
Configuration Manager has always provided a large centralized store of device data, which customers use for reporting purposes. The site typically collects this data on a weekly basis. Starting in version 1806, CMPivot is a new in-console utility that now provides access to real-time state of devices in your environment. It immediately runs a query on all currently connected devices in the target collection and returns the results. Then filter and group this data in the tool. By providing real-time data from online clients, you can more quickly answer business questions, troubleshoot issues, and respond to security incidents.
For example, in mitigating speculative execution side channel vulnerabilities, one of the requirements is to update the system BIOS. You can use CMPivot to quickly query on system BIOS information, and find clients that aren't in compliance.
The following components are required to use CMPivot:
Upgrade the target devices to the latest version of the Configuration Manager client.
The Configuration Manager administrator needs the Read permission on the SMS Scripts object, the Run Scripts permission on the Collection, and the default scope. The Scripts Runner role has these permissions, which isn't created by default. For more information on creating this custom security role, please see Security roles for scripts.
To gather data for the following entities, target clients require PowerShell version 5.0:
In a hierarchy, connect the Configuration Manager console to a primary site to run CMPivot. The Start CMPivot action doesn't appear in the console when it's connected to a central administration site.
CMPivot only returns data for clients connected to the current site.
If a collection contains devices from another site, CMPivot results are only from devices in the current site.
You can't customize entity properties, columns for results, or actions on devices.
Only one instance of CMPivot can run at the same time on a computer that is running the Configuration Manager console.
In version 1806, the query for the Administrators entity only works if the group is named "Administrators". It doesn't work if the group name is localized. For example, "Administrateurs" in French.
In the Configuration Manager console, connect to the primary site. Go to the Assets and Compliance workspace, and select the Device Collections node. Select a target collection, and click Start CMPivot in the ribbon to launch the tool.
If you don't see this option, check the following configurations:
Confirm with a site administrator that your account has the required permissions. For more information, see Prerequisites.
Connect the console to a primary site.
The interface provides further information about using the tool.
Manually enter query strings at the top, or click the links in the in-line documentation.
Click one of the Entities to add it to the query string.
The links for Table Operators, Aggregation Functions, and Scalar Functions open language reference documentation in the web browser. CMPivot uses the same query language as Azure Log Analytics.
Keep the CMPivot window open to view results from clients. When you close the CMPivot window, the session is complete.
If the query has been sent, then clients still send a state message response to the server.
How to use CMPivot
The CMPivot window contains the following elements:
The collection that CMPivot currently targets is in the title bar at the top, and the status bar at the bottom of the window. For example, All Systems in the above screenshot.
The pane on the left lists the Entities that are available on clients. Some entities rely upon WMI while others use PowerShell to get data from clients.
Right-click an entity for the following actions:
Insert: Add the entity to the query at the current cursor position. The query doesn't automatically run. This action is the default when you double-click an entity. Use this action when building a query.
Query all: Run a query for this entity including all properties. Use this action to quickly query for a single entity.
Query by device: Run a query for this entity and group the results. For example,
Disk | summarize dcount( Device ) by Name
Expand an entity to see specific properties available for each entity. Double-click a property to add it to the query at the current cursor position.
The Home tab shows general information about CMPivot, including links to sample queries and supporting documentation.
The Query tab displays the query pane, results pane, and status bar. The query tab is selected in the above screenshot example.
The query pane is where you build or type a query to run on clients in the collection.
CMPivot uses a subset of the same query language as Azure Log Analytics.
Cut, copy, or paste content in the query pane.
By default, this pane uses IntelliSense. For example, if you start typing
D, IntelliSense suggests all of the entities that start with that letter. Select an option and press Tab to insert it. Type a pipe character and a space
|, and then IntelliSense suggests all of the table operators. Insert
summarizeand type a space, and IntelliSense suggests all of the aggregation functions. For more information on these operators and functions, click the Home tab in CMPivot.
The query pane also provides the following options:
Run the query.
Move backwards and forwards in the history list of queries.
Create a direct membership collection.
Export the query results to CSV or the clipboard.
The results pane displays the data returned by active clients for the query.
The available columns vary based upon the entity and the query.
Click a column name to sort the results by that property.
Right-click on any column name to group the results by the same information in that column, or sort the results.
Right-click on a device name to take the following additional actions on the device:
Pivot to: Query for another entity on this device.
Run Script: Launch the Run Script wizard to run an existing PowerShell script on this device. For more information, see Run a script.
Remote Control: Launch a Configuration Manager Remote Control session on this device. For more information, see How to remotely administer a Windows client computer.
Right-click on any non-device cell to take the following additional actions:
Copy: Copy the text of the cell to the clipboard.
Show devices with: Query for devices with this value for this property. For example, from the results of the
OSquery, select this option on a cell in the Version row:
OS | summarize countif( (Version == '10.0.17134') ) by Device | where (countif_ > 0)
Show devices without: Query for devices without this value for this property. For example, from the results of the
OSquery, select this option on a cell in the Version row:
OS | summarize countif( (Version == '10.0.17134') ) by Device | where (countif_ == 0) | project Device
Bing it: Launch the default web browser to www.bing.com with this value as the query string.
Click any hyperlinked text to pivot the view on that specific information.
The results pane doesn't show more than 20,000 rows. Either adjust the query to further filter the data, or restart CMPivot on a smaller collection.
The status bar shows the following information (from left to right):
The status of the current query to the target collection. This status includes:
The number of active clients that completed the query (3)
The number of total clients (5)
The number of offline clients (2)
Any clients that returned failure (0)
Query completed on 3 of 5 clients (2 clients offline and 0 failure)
The ID of the client operation. For example:
The current collection. For example:
The total number of rows in the results pane. For example,
The following sections provide examples of how you might use CMPivot in your environment:
Example 1: Stop a running service
Your security administrator asks you to stop and disable the Computer Browser service as quickly as possible on all devices in the accounting department. You start CMPivot on a collection for all devices in accounting, and select Query all on the Service entity.
As results appear, you right-click on the Name column and select Group by.
Service | summarize dcount( Device ) by Name
In the row for the Browser service, you click the hyperlinked number in the dcount_ column.
Service | where (Name == 'Browser') | summarize count() by Device
You multi-select all devices, right-click the selection, and choose Run Script. This action launches the Run Script wizard, from which you run an existing script you have for stopping and disabling a service. With CMPivot you quickly respond to the security incident for all active computers, viewing results in the Run Script wizard. You then followup to create a configuration baseline to remediate other computers in the collection as they become active in the future.
Example 2: Proactively resolve application failures
To be proactive with operational maintenance, once a week you run CMPivot against a collection of servers that you manage, and select Query all on the AppCrash entity. You right-click the FileName column and select Sort Ascending. One device returns seven results for sqlsqm.exe with a timestamp about 03:00 every day. You select the file name in one of the rows, right-click it, and select Bing It. Browsing the search results in the web browser, you find a Microsoft support article for this issue with more information and resolution.
Example 3: BIOS version
To mitigate speculative execution side channel vulnerabilities, one of the requirements is to update the system BIOS. You start with a query for the BIOS entity. You then Group by the Version property. Then right-click a specific value, such as "LENOVO - 1140", and select Show devices with.
Bios | summarize countif( (Version == 'LENOVO - 1140') ) by Device | where (countif_ > 0)
Example 4: Free disk space
You need to temporarily store a large file on a network file server, but aren't sure which one has enough capacity. You start CMPivot against a collection of file servers, and query the Disk entity. You modify the query for CMPivot to quickly return a list of active servers with real-time storage data:
Disk | where (Description == 'Local Fixed Disk') | where isnotnull( FreeSpace ) | order by FreeSpace asc
CMPivot sends queries to clients using the Configuration Manager "fast channel". This communication channel from server to client is also used by other features such as client notification actions, client status, and Endpoint Protection. Clients return results via the similarly quick state message system. State messages are temporarily stored in the database.
The queries and the results are all just text. The entities InstallSoftware and Process return some of the largest result sets. During performance testing, the largest state message file size from one client for these queries was less than 1 KB. Scaled to a large environment with 50,000 active clients, this one-time query would generate less than 50 MB of data across the network.
A query times out after one hour. For example, a collection has 500 devices, and 450 of the clients are currently online. Those active devices receive the query and return the results almost immediately. If you leave the CMPivot window open, as the other 50 clients come online, they also receive the query, and return results.
CMPivot interations are logged to the following log files:
