You can override the system default syslog templates.

To use a new template, add one of the following entries to /etc/cb/cb.conf :

BinaryInfoSyslogTemplateGroupObserved=/etc/cb/my_bininfo_group_observed_template.txt
BinaryInfoSyslogTemplateHostObserved=/etc/cb/my_bininfo_host_observed_template.txt
BinaryInfoSyslogTemplateObserved=/etc/cb/my_bininfo_observed_template.txt
FeedIngressSyslogTemplateBinary=/etc/cb/my_feed_ingress_binary_template.txtx
FeedIngressSyslogTemplateProcess=/etc/cb/my_feed_ingress_process_template.txt
FeedStorageSyslogTemplateBinary=/etc/cb/my_feed_storage_binary_template.txt
FeedStorageSyslogTemplateProcess=/etc/cb/my_feed_storage_process_template.txt
WatchlistSyslogTemplateBinary=/etc/cb/my_wathlist_process_template.txt
WatchlistSyslogTemplateProcess=/etc/cb/my_watchlist_binary_template.txt
FeedQuerySyslogTemplateBinary=/etc/cb/my_feed_query_binary_template.txt
FeedQuerySyslogTemplateProcess=/etc/cb/my_feed_query_process_template.txt

The watchlist search process will automatically pick up the new template when the next watchlist hit occurs.
