(Required) Enter the serial number of the Panorama appliance that functions as the Log Collector. If the Log Collector is local, enter the serial number of the Panorama management server. Select the certificate that the managed collector must use to securely ingest logs from the Traps™ ESM server. This certificate is called an inbound certificate because the Panorama/ Managed Collector is the server to which the Traps ESM (client) is sending logs; the certificate is required if the Transport protocol for the log ingestion profile is SSL. Select a certificate for secure forwarding of syslogs to an external Syslog server. The certificate must have the Certificate for Secure Syslog option selected (see Manage Firewall and Panorama Certificates). When you assign a Syslog server profile to the Collector Group that includes this Log Collector (see Panorama > Collector Groups, Panorama > Collector Groups > Collector Log Forwarding), the Transport protocol of the server profile must be SSL (see Device > Server Profiles > Syslog). (Optional) Enter the IP address a secondary DNS server to use if the primary server is unavailable. (Optional) Enter the IP address or host name of secondary NTP servers to use if the primary server is unavailable.
