Markers
Markers unambiguously assign semantics to individual log messages.

Examples
Marker formatting is using tabs -
| Jira Legacy | ||||||
|---|---|---|---|---|---|---|
|
Note there are 3 tabs (see p_mak in logback.xml) delimiting the MARKERS (ENTRY and EXIT) at the end of each line
<property name="p_mak" value="%replace(%replace(%marker){'\t', '\\\\t'}){'\n','\\\\n'}"/>| Code Block | ||||
