Configuring SMB file share destinations

Server Message Block (SMB) file share destinations are not supported with Tanium Cloud.

You can send information from a connection source to a Server Message Block (SMB) file share.


  • Connect 4.13.4 or later.
  • For Tanium Module Server on Tanium Appliance, 1.6.0 or later.
  • For Tanium Module Server on Windows, any supported version.

Specify general connection information

  1. On the Connect Overview page, scroll to the Connections section and click Create Connection.
  2. Enter a name and description for the connection.
  3. (Optional) In the General Information section, expand Advanced to configure the following settings:

    Log Level

    By default, Log Level is set to Information. To reduce the amount of logging, you can set Log Level to Warning, Error, or Fatal.

    Override Log Level

    If you are debugging the connection, select Override Log Level to set a Temporary Log Level (such as Trace or Debug) on this connection for a selected Number of Runs (up to 24). A scheduled or manual connection run, once started, counts towards the number of runs, regardless of the connection status. After the number of runs elapse, the logging for this connection returns to the Log Level you selected to prevent finer-grained logging from consuming additional resources for an indefinite number of runs.

    Minimum Pass Percentage

    Minimum percentage of the expected rows that must be processed for the connection to succeed.

    Memory Ceiling (GB)

    Maximum memory for the node process to run the connection. This defaults to 1 GB per connection, and cannot exceed the global maximum sum of memory for all running connections (by default, 8 GB). Increase this setting if a connection frequently exhibits out of memory errors while running.

    If the sum of simultaneously scheduled connection Memory Ceiling values exceed the global Memory Ceiling, connections run until the global Memory Ceiling is reached, then any remaining connections enter a waiting queue if you select the Queue Connections configuration setting, or fail if you clear the Queue Connections configuration setting.

Configure the connection source

The connection source determines what data you are sending to the destination. This data is usually information from Tanium, such as a saved question, question log, client status, or event. The settings vary depending on which source you choose.

If a Tanium solution or source displays Critical , the installed solution does not meet the minimum required version for proper compatibility and functionality. Upgrade the solution to the minimum required version or later.

After you create a connection, you cannot update the connection source type, only the source configuration. If you want to change the source type, create a new connection.

Configure the SMB file share destination

Specify details about the file share that you want Connect to send the data.

After you create a connection, you cannot update the connection destination type, only the destination configuration. If you want to change the destination, create a new connection.

  1. Name the destination.
    • Specify a unique name to save the configuration information as a new destination. Select New, and then enter a Destination Name.

    • Copy an existing destination. Select New, and then click Copy Settings. Select a destination from the drop-down list, click Apply, and update the Destination Name.

    • Select an existing destination. Select Existing, and then select a destination from the Destination Name drop-down list.

      Configure a unique destination per connection. If you edit the settings for a shared destination for one connection, any other connections that use the shared destination are affected, and connection runs might fail.

  2. Specify the server name.

    The server must support NTLM authentication.

  3. Specify the share name, or use a variable as listed in Reference: Variables.
  4. (Optional) Specify the directory name, or use a variable as listed in Reference: Variables.
  5. Specify the file name, or use a variable as listed in Reference: Variables.
  6. (Optional) Specify the domain or workgroup of the user.
  7. Specify the user name and password to access the file share.
  8. (Optional) Enter an SMB connection Timeout in seconds to increase the time available to complete a file transfer before the SMB connection times out.

Configure filters

(Optional) In the Configure Output > Filters section, you can specify filters to modify the data that you are getting from your connection source before it is sent to the destination.

For more information about the types of filters you can configure, see Reference: Filtering options.

Format data for SMB file share

You can choose to save your file in any of the available formats, as listed in Reference: Format types. Each format has slightly different configuration options, but all allow you to choose which column data to save.

In the Configure Output > Columns section, you can change the Destination Label of each column and Value Type to force the column to be a String, Numeric, or Date/Time value.

If you choose Numeric for the value, you can specify a default value that is used if the data cannot be coerced into a numeric value. You can specify any negative or positive number.

If you choose Date/Time for the value, specify the format that you want to use for the column. For more information about using a variable, see Time stamp variables.

For more information about column customizations, see Reference: Column customizations.

Schedule the connection

Connections can run at a highly configurable time interval, such as multiple times per hour, day, week, or month.

Connections scheduled to run during a Tanium Cloud maintenance window might be interrupted or fail. Schedule your connections to run outside of the Tanium Cloud maintenance window. For information on configuring a custom maintenance window start time, see Tanium Cloud Deployment Guide: Configure custom maintenance window.

Connections scheduled to run during an upgrade of Connect, or any Tanium solution configured as a connection source, might be interrupted or fail. Schedule your connections to run at a different time than your Tanium upgrades.

If you do not enable the schedule, the connection only runs when you manually run it, unless you configure an Event source. Connections with Event sources only run when a configured event is detected, and cannot be scheduled or manually run.

Use the Schedule section to update the schedule:

  • Select Enable schedule.
  • In the Schedule Type, select Basic to build a schedule with the provided controls.
  • To view or edit the cron expression directly, select Advanced - Define as a Cron Expression, and use the Advanced field to edit the cron expression.

If a user that owns a scheduled connection is deleted, future scheduled instances of that connection do not run. For more information, see Issue: Scheduled connection owned by a deleted user no longer runs.

For more information about cron syntax, see Reference: Cron syntax.

Save and verify connection

  1. After you enter the details for the connection, click Save.

    To save the connection and immediately run the connection, click Run and Save.

    If needed, resolve any errors or missing information. After the connection creates successfully, the connection details display.

  2. To view details when the connection runs, click the Logs tab.
  3. To view an individual run log, expand the row table. For more information on resolving errors, see Troubleshooting.
