Configuring email destinations
Before your connections can successfully send data to a destination, your Tanium Cloud instance, CMP network egress allow list, and network allow list must be configured. Note the following:
- Sign in to the CMP and configure a network egress allow list rule for each destination fully qualified domain name (FQDN) and associated port. For more information on configuring the network egress allow list, see Tanium Cloud Deployment Guide: Configuring network egress allow list rules in the CMP.
- Tanium Cloud does not support non-TLS plaintext HTTP URLs.
Tanium does not support sending data over TCP port 25 outbound. If you create a rule with external access for an SMTP email server destination (default TCP port 465 or TCP port 587), you can only associate the port with 1 FQDN.
For other destinations, you can reuse a port for multiple destination FQDNs.
Your Tanium Cloud instance has a proxy cluster with 2 public IP addresses. If a destination is in your network, add inbound traffic from these IP addresses to your network allow list.
You can send information from a connection source to a set of email addresses. You can either include the results in the email body, or create an attachment.
- Email addresses for sending and receiving email results.
- Information about your mail server, including host, port, user name, password, and authentication information.
- On the Connect Overview page, scroll to the Connections section and click Create Connection.
- Enter a name and description for the connection.
- (Optional) In the General Information section, expand Advanced to configure the following settings:
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.
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.
The action history is a record of all actions issued by console operators. To view this record in Tanium, go to Administration > Actions > Action History. For more information, see Tanium Console User Guide: Manage actions that are completed or in progress.
Client Status, previously named System Status, includes the state of all the endpoints, including some useful information about the endpoint like IP Address, position in the network, and the last time it registered with the Tanium Server. For more information about the Client Status data, see Tanium Console User Guide: View the status of Tanium Client registration and communication.
Tanium solutions, like Tanium™ Discover,
The question history log is a history of every question that has been asked. When you are using the question log as a data source in Connect, you can filter the log in several ways to reduce the total volume of data being sent. For more information, see Tanium Console User Guide: Question history.
A saved question is a Tanium question that you want to ask on a repeated basis. For more information about saved questions, see Tanium Interact User Guide: Managing saved questions.
When you select a saved question as a source, the Computer Group drop-down defaults to No Filter, which does not filter the saved question with a computer group. Select No Filter if you want to send recent saved question results from all endpoints to the destination. The endpoint results are subject to the computer group management rights of the user configuring the connection, and might not match the endpoint membership of the All Computers computer group. Select the All Computers computer group if you want to explicitly filter the saved question on the All Computers computer group.
You can use the following settings for saved question sources:
|Flatten Results||You might want to enable the Flatten Results setting to process results as individual records. For example, you might want to get notified when you see a new MD5 hash on a machine. Without the Flatten Results setting enabled, the entire data set that is retrieved by the saved question from a machine, such as all MD5 hashes, is considered to be a single record. Any change that is made to this data set shows up in the destination. By enabling the Flatten Results setting, Connect processes the new hashes on an individual basis (one MD5 hash from one machine) instead of all hashes from a machine as a single record.|
|Hide Errors||If the saved question returns an error, you can use the Hide Errors setting to prevent the error results from getting sent to the destination.|
|Hide No Results||If the saved question returns [No results], you can use the Hide No Results setting to prevent this result from being sent to the destination.|
|Include Recent Answers||
If you want to include results from machines that are offline, select Include Recent Answers, which returns the most recent answer to the saved question for the offline endpoint.
If you select Include Recent Answers, for the best results, you should also select No Filter from the Computer Group drop-down.
|Answer Complete Percent||Results are returned when the saved question returns the configured complete percent value. Any results that come in after the configured percent value has passed are not sent to the destination. If you are finding that the data returned from the saved question is incomplete in your destination, you can disable this setting by setting it to 0. If disabled, all data is returned after the timeout passes.|
|Timeout||Minutes to wait for clients to reply before returning processed results when Answer Complete Percent is set to 0. If the Answer Complete Percent value is not met at the end of the time limit, then the connection run is marked as a failure. The maximum timeout is 10 minutes.|
|Batchsize||Number of rows that are returned for the saved question results at one time. This setting might vary depending on your destination.|
Server Information Source
Use the server information in the following location as a connection source: https://<tanium_server>/info.json.

- Provide the host name, port, user name, and password.
Select Secure if the connection with the SMTP server is authenticated and uses TLS encryption.
Tanium Cloud does not support using self-signed certificates for authentication with an SMTP server. You must provide a CA-signed certificate.
If you do not select Secure, authentication information is encrypted at rest, but passed unencrypted to the destination.
- Specify a Timeout value for sending the message. The default is 0, which means that there is no timeout. A recommended timeout value is 10 seconds.
If you submit an external access request for traffic, your configured destination FQDN or IP address, port, and protocol must match the FQDN or IP address, port, and protocol submitted in the external access request.
- (Optional) Specify advanced settings. Some fields also support variable substitution, as listed in Reference: Variables.
- You can configure CC and BCC addresses for the email and specify the settings for the email attachment.
- If you specify an Attachment File Name, include a file extension with the file name. The file extension does not need to match the format option you select in the Format section. Note the option that you select in the Format section does not add or change the file extension.
- You can compress the attachment into a zip or gzip file. If you select a compression method, the file extension for the compression method is automatically added to the end of the file name.
(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.
You can choose from any of the available formats for your email. The data is sent in the body of the email by default.
If you want to attach a file to the email instead of having the data in the body of the email, edit the Advanced settings for the Email destination and select Attachment. Specify a file name and whether the file should be compressed.
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.
Connections can run at a highly configurable time interval, such as multiple times per hour, day, week, or month.
