SSL Certificate Checker

Splunk Cloud
Overview
Details
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!

Many thanks to Christian Cloutier (https://answers.splunk.com/users/229355/christian.cloutier.html) for the idea behind this app as well as development efforts.

IF YOU LIKE THIS APP, PLEASE LEAVE A RATING. THANKS IN ADVANCE!!!

Troubleshooting directions are provided under the details tab here on Splunkbase.

THIS APP WORKS ON SPLUNK CLOUD and ENTERPRISE - BUT NOT UNIVERSAL/LIGHT FORWARDERS

  • Doesnt work on Universal Forwarders / Light Forwarders
  • Requires Splunk's built in Python 2.7 and OpenSSL binaries / libraries
  • Tested on AWS Linux

Installation Instructions

1st - Install the app, and restart Splunk
2nd - Setup your own Splunk searches, alerts, dashboards (see index=main by default)
3rd - Profit

Troubleshooting:

Be sure the python scripts in /bin are executable ("chmod +x /path/to/ssl_checker/bin/.py")
Be sure to restart Splunk after configuration (Enables scripted inputs)
Check for logged errors ("index=_internal log_level=err
OR log_level=warn ssl_checker")
