short_description: Sends task result events to Splunk HTTP Event Collector
author: "Stuart Hirst (!UNKNOWN) <support@convergingdata.com>"
description:
- This callback plugin will send task results as JSON formatted events to a Splunk HTTP collector.
- The companion Splunk Monitoring & Diagnostics App is available here U(https://splunkbase.splunk.com/app/4023/).
- Credit to "Ryan Currah (@ryancurrah)" for original source upon which this is based.
requirements:
- Whitelisting this callback plugin
- 'Create a HTTP Event Collector in Splunk'
- 'Define the URL and token in C(ansible.cfg)'
options:
url:
description: URL to the Splunk HTTP collector source.
env:
- name: SPLUNK_URL

key: url
authtoken:
description: Token to authenticate the connection to the Splunk HTTP collector.
env:
- name: SPLUNK_AUTHTOKEN
ini:
- section: callback_splunk
key: authtoken
validate_certs:
description: Whether to validate certificates for connections to HEC. It is not recommended to set to
V(false) except when you are sure that nobody can intercept the connection
between this plugin and HEC, as setting it to V(false) allows man-in-the-middle attacks!

sent to the Splunk HTTP collector.
