HI,
Is there anyway in splunk to set the "email" as default trigger action for an alert.
You can use [default]
stanza in savedsearches.conf to assign an attribute to all saved searches. You can use attributes described in below link to setup your email alert.
http://docs.splunk.com/Documentation/Splunk/6.5.3/Admin/Savedsearchesconf#Settings_for_email_action
Please note that this will get applied to all scheduled searches (unless overridden at search level).
Can i set the webhook as default trigger action as in the documentation i see only for email.
