Very limited. You can subscribe to CONFD_NOTIF_NETCONF events and your subscriber would get data structured according to
struct confd_syslog_notification {
int prio; /* from syslog.h */
int logno; /* number from confd_logsyms.h */
char msg[BUFSIZ];
}
where some of what you ask for is in the message field. See the misc/notification example: do make START_FLAGS=-N all start, run NETCONF requests and watch the output to see if there is what you need.
