+ * Check a host's certificate
+ *
+ * This command utilizes this module's database to check if the given host serves valid certificates.
+ *
+ * USAGE
+ *
+ * icingacli x509 check host [options]
+ *
+ * OPTIONS
+ *
+ * You can either pass --ip or --host or both at the same time but at least one is mandatory.
+ *
+ * --ip A hosts IP address
+ * --host A hosts name
+ * --port The port to check in particular
+ * --warning Less remaining time results in state WARNING
+ * Default: 25%
+ * --critical Less remaining time results in state CRITICAL
+ * Default: 10%
+ * --allow-self-signed Ignore if a certificate or its issuer has been
+ * self-signed
+ *
+ * EXAMPLES
+ *
+ * icingacli x509 check host --ip 10.0.10.78
+ * icingacli x509 check host --host mail.example.org
+ * icingacli x509 check host --ip 10.0.10.78 --host mail.example.org --port 993
+ *
+ * THRESHOLD DEFINITION
+ *
+ * Thresholds can either be defined relative (in percent) or absolute
+ * (time interval). Time intervals consist of a digit and an accompanying
+ * unit (e.g. "3M" are three months). Supported units are:
+ *
+ * Year: y, Y
+ * Month: M
+ * Day: d, D
+ * Hour: h, H
+ * Minute: m
+ * Second: s, S
