https://www.paessler.com/manuals/prtg/ssl_certificate_sensor describes the sensor has having;
Days to expiration (with predefined lower warning and error limits)
However I cannot find any documentation of what these predefined limits are, if they do exist.
All my SSL sensors show "Days to Expiration" as green all the way down to 0 days, which makes me concerned that qthere is no lower limit.
I can obviously manually set a warning and error limit on each and every sensor, but I'd rather not have to edit individual sensors.
Alternatively I could look at customising the OVL file, but there's no prtg.standardlookups.sslcertificatesensor.*.ovl file for expiration (and if the sensor handles it then why would I?).
How many days until expiry will this sensor warn and when will it error?
Thanks
