The SSL Certificate Checker Technology Add-on contains scripts and inputs designed to index the expiration date and name of the SSL certificates you want to monitor. From there you can setup a dashboard/report/alert to monitor when your SSL certificates are about to expire. This is a great tool for monitoring Splunk's Web / Frontend & Splunk's Daemon / Backend SSL certificates both if you've specified your own or if you're using the built in certificates. Now supports automated discovery mode that finds the PEM files you're using to encrypt your Splunk traffic and indexes their expiration date. Use the dashboard provided as an example to configure alerts, and never let a Splunk cert expire again!
