Hi @khozy,

yes, there are at least two ways to check ssl certificates :

  1. Use the ssl check of check_http that actively connects and checks SSL Certificates of websites / webservices
  2. Use the check written by @r.sander for local certificates in windows and linux :


Thanks. Do you any instructions on how to use the Option 2 within CMK?

Any help you can provide with instructions on how to use the option 2 plugin as per your suggestion?


frst you need to download and install the mkp File.
After that there will be new rules for the deployment and configuration of the monitoring of the SSL certificates you want to monitor.
If you are using Enterprise Edition you can configure the plugin deployment in the agent bakery.
