Hello everyone, Was wondering if it possible for Observium to create an alert for https certificate validity check? Anyone managed to do this or is it not possible? In an ideal case I want an alert 90 days before the certificate expires. With kind regards David S. _______________________________________________ observium mailing list observium@observium.org http://postman.memetic.org/cgi-bin/mailman/listinfo/observium
