Email notification action

You can configure an alert to send an email notification to specified recipients when the alert triggers. You can send the email notification as a multipart MIME message that includes both HTML and text parts. You can also send the notification as plain text.

You configure the email notification action for an alert when you save the alert from the Search page. You can also configure email notification from the Alerts Page and directly from a search command.

Email notification contexts

There are several contexts from which you can send email notifications. The email options available differ, depending on the context.

• Alert actions
  Send email notifications as an alert action from a search. Specify the notification from the Search Page, a listing in the Alerts Page, or directly from the search command.

• Scheduled report
  Configure email notifications for a scheduled report either from a listing in the Reports Page or from a report.

• Scheduled PDF delivery of dashboards
  Configure PDF delivery either from a listing in the Dashboards Page or from a dashboard.

This topic covers alert actions from a search job. See Schedule reports and Generate Dashboard PDFs for information on the other contexts for email notification.

Configure email notification for alerts

You can configure email notifications when you save a search as an alert. You can also configure email notifications for when editing an alert's actions. The procedure is the same in both cases.

After running a search, save the search as an alert and configure email notification settings.

1. Run the search.
2. Select Save As > Alert.
3. Provide a Title and other information about the alert.
4. From the Add Actions menu, select Send email.
   
   
   
   
5. Specify the following:
   
   
   • To, CC, and BCC email recipients.
     Specify a comma-separated list of email recipients.
   • Priority
     Enforcement of priority depends on your email client.
   • Subject
   • Message
   • Include
     You can include the following items:
     
     Information about the search
       Link to the alert
       Search string
       Trigger condition
       Trigger time
     
     Information about search results
       Link to results
       Inline listing of results, as a table, raw events, or CSV file
       Results as a PDF attachment
       Results as a CSV attachment
   • Type
     Select HTML & Plain Text (multi-MIME message) or Plain Text
6. Specify other alert actions.
   See set up alert actions for more information.
7. Click Save.

Send email notification from a search command

You can send email notifications directly from the sendemail search command. For example:

index=main | head 5 | sendemail to=example@splunk.com server=mail.example.com subject="Here is an email notification" message="This is an example message" sendresults=true inline=true format=raw sendpdf=true

See the sendemail command listing in the Search Reference for details.

Send email to different recipients based on search results

This search example works with a token in the To email notification field to handle different notifications based on the result count. If there are more than 3500 results, a notification goes to recipient1. If there are fewer than 500 results, the notification goes to recipient2. If neither condition applies, then no notification is sent.

Here is the search.

"error" | stats count | eval recipient=case(count > 3500, "recipient1@domain.com", count >= 500, "recipient2@domain.com", 1==1, null()) | where isnotnull(recipient)

When the search is saved as an alert, configure the Send email alert action with the following token in the To recipient field.

$result.recipient$

Use tokens in email notifications

A token is a type of variable that represents data generated by a search job. Splunk Enterprise provides tokens that you can use to include information generated by a search in the fields of an email:

• To
• Cc
• Bcc
• Subject
• Message
• Footer

Access the value of a token with the following syntax:

$<token-name>$

For example, place the following token in the subject field of an email notification to reference the search ID of a search job.

Search results from $job.sid$

Tokens available for email notifications

This section lists common tokens you can use in email notifications. There are four categories of tokens that access data generated from a search. The context for using the tokens differ.

Category	Description	Context

Search results	Access results of a search	Alert actions from search Scheduled reports
Job information	Data specific to a search job	Alert actions from search Scheduled reports
Server information	Information about the Splunk Enterprise server	Alert actions from search Scheduled reports Scheduled PDF delivery of dashboards

In addition to the common tokens listed in this topic, the savedsearches.conf and alert_action.conf configuration files list attributes whose values are available from tokens. To access these attribute values, place the attribute between the '$' token delimiters. For example, to access the subject of an email notification, reference the following attribute listed in savedsearches.conf:

$action.email.subject$

User role configuration to schedule PDF delivery of dashboards
