Which of the following best represents the information that is typically contained in the debug output?

Ping products (e.g., PingFederate, PingAccess) write debug entries in the same Log4j-based format.

Each record begins with a timestamp header, then the Java thread ID, the originating component (logger name), the configured log level, and the human-readable message. When an exception occurs, a full Java stack trace is appended. Option A lists every one of those mandatory and optional parts; the other options each omit at least one required element.

B – Omits the running thread ID, which is always written.

C – Omits the debug level.

D – Omits the component/logger name.

1. PingFederate 11.3 Administrative Guide, “Server logging,” §3.4.1, p. 135–136 – describes timestamp, thread, logger, level, message, stack trace.

2. PingAccess 9.2 Admin Guide, “Understanding log files,” p. 47 – identical field list for DEBUG output.

3. Apache Log4j 2 Manual, “Layout,” §PatternLayout – corroborates required fields for Ping’s default pattern.
