Bug ID 1106521: Boot Marker logs missing ISO formatted date

Last Modified: Feb 14, 2024

Affected Product(s):
BIG-IP All(all modules)

Known Affected Versions:
15.1.4, 15.1.4.1, 15.1.5, 15.1.5.1, 15.1.6, 15.1.6.1, 15.1.7, 15.1.8, 15.1.8.1, 15.1.8.2, 15.1.9, 15.1.9.1, 15.1.10, 15.1.10.2, 15.1.10.3

Opened: May 13, 2022

Severity: 1-Blocking

Symptoms

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.

Impact

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).

Conditions

This occurs on affected BIG-IP v15.1.x versions starting with BIG-IP v15.1.4.
