Hi Akla,

The sensor can only monitor HTTPS certificates. Are those certificates stored in the Windows cert store? If so, you could use the WinCertExpiration Sensor from PRTGToolsFamily to monitor it.

Kind regards,

I got it to work also, but from the command line. How do I incorporate that into PRTG with an alert for 30 days till expiration?


WinCertExpiration.exe -h=hhradius1 -t=3b7b47e9fc4218e3c161e0bee2cfdee068830627 -s=My 

Connecting to certificate store LocalMachine/My on remote machine.
Enummerating certificates in My store.......
271:The certificate expires in 271 days.

an alert can be triggered with putting a limit onto the channel which shows time until expiration.

Please also make sure the sensor has a notification trigger inherited (or an individual one created) alerting on the status set by the limit.
