Most applications today run as replica sets (k8s pods/VM asgs) so log aggregators are another interesting part of the problem. Most shops are moving to saas logging for log collection which presents another failure mode: your logs are only as reliable as the saas provider. It is true however that looking at the individual replica, application logs should be very reliable.
