Splunk Cloud Platform

Search Reference

sendemail

Description

Use the sendemail command to generate email notifications. You can email search results to specified email addresses.

You must have a Simple Mail Transfer Protocol (SMTP) server available to send email. An SMTP server is not included with the Splunk instance.

This command is considered risky because, if used incorrectly, it can pose a security risk or potentially lose data when it runs. As a result, this command triggers SPL safeguards. See SPL safeguards for risky commands in Securing the Splunk Platform.

server
Syntax: server=<host>[:<port>]
Description: If the SMTP server is not local, use this argument to specify the SMTP mail server to use when sending emails. The <host> can be either the hostname or the IP address. You have the option to specify the SMTP <port> that the Splunk instance should connect to.
If you set use_ssl=true, you must specify both <host> and <port> in the server argument.
This setting takes precedence over the mailserver setting in the alert_actions.conf file. The default setting for mailserver is localhost:25.

If an alert action is configured to send an email notification when an alert triggers, the sendemail command might not be able to use the server you specify in the server argument. The values in the Email domains setting on the Email Settings page might restrict the server you can use. The sendemail command uses the Mail host that is set on the Email Settings page. For more information, see Email notification action in the Alerting Manual.

Usage

If you set sendresults=true and inline=false and do not specify format, a CSV file is attached to the email.

If you use fields as tokens in your sendemail messages, use the rename command to remove curly brace characters such as { and } from them before they are processed by the sendemail command. The sendemail command cannot interpret curly brace characters when they appear in tokens such as $results$.

Capability requirements

To use sendemail, your role must have the schedule_search and list_settings capabilities.

Examples

1: Send search results to the specified email

Send search results to the specified email. By default, the results are formatted as a table.

... | sendemail to="elvis@splunk.com" sendresults=true

2: Send search results in table format

Send search results in a raw format with the subject "myresults".

... | sendemail to="elvis@splunk.com,john@splunk.com" format=raw subject=myresults server=mail.splunk.com sendresults=true

3. Include a PDF attachment, a message, and raw inline results

Send an email notification with a PDF attachment, a message, and raw inline results.

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

4: Use email notification tokens with the sendemail command

You can use the eval command in conjunction with email notification tokens to customize your search results emails. The search in the following example sends an email to sample@splunk.com with a custom message that says sample sendemail message body.

|makeresults |eval custommessage="sample sendemail message body" |eval dest="sample@splunk.com" |sendemail to="$result.dest$" message="$result.custommessage$"

See Use tokens in email notifications in the Splunk Cloud Platform Alerting Manual.
