Opened: May 13, 2022 Severity: 1-Blocking
On affected BIG-IP v15.1.x versions starting with BIG-IP v15.1.4, boot_marker log messages marking system startup events do not include ISO formatted dates.
1. For log files covering a long period of time, it may not be obvious in which year a particular recorded boot event occurred, and the precise timing much be inferred by other data. 2. The ISO date format is not used for boot_marker logs when ISO date format is enabled (tmsh modify sys syslog iso-date enable), breaking ICSA compliance. 3. The boot_marker log message format is inconsistent with other BIG-IP versions (v14.1.x and earlier, v16.0.0 and later).
This occurs on affected BIG-IP v15.1.x versions starting with BIG-IP v15.1.4.
