Investigating the logging and tracing output for the application server is an excellent way to observe performance, diagnose problems, and gain a general understanding of how the application server is working within your environment. The expected output locations for logging and trace information can be different depending on the operating system on which the application server is running.
Log or trace stream | Expected output |
---|---|
Tracing (both native trace and Java tracing) | SYSPRINT![]() |
Tracing level equal to the Audit level | Transformed into write-to-operator (WTO) output to the hard copy logging stream |
Tracing level equal to or above the Detail level | SYSOUT or your configured error stream |
Messages, including native messages and most trace messages | SYSOUT or your configured error stream |
System.out | SYSPRINT |
System.err | SYSPRINT |
