This sets the minimum severity level, from panic (the most severe, and the CLI name for what the pre-filter table calls emergency) down through debug, that a message must meet to be forwarded to the configured Syslogd server; anything below this threshold is not forwarded even though it may still be logged locally. This is a second, independent severity filter layered on top of sysEvtLogPreFilterSeverity, letting an admin log more detail locally than gets sent to the remote syslog server. For example, keeping the local pre-filter at debug while setting this Syslogd threshold to warning would let an admin retain full local detail while only burdening the remote syslog server with warning-and-above events.
