CLIENT-CERT 
Checks that the client certificate to download Icinga and other configuration generated on Sown-auth2 is not expired. This is checked via an Admin Site check script and returns CRITICAL if the certificate has expired or will expire in the next 30 days. It reports WARNING if the certificate will expire in the next 90 days.
IDO2DB
