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.
