Opened: Apr 02, 2015
Severity: 4-Minor

Symptoms

When configuring the time zone for a BIG-IP system, the time zone selection may not be applied to the AOM subsystem. In this case, the time zone for the AOM subsystem will be set to UTC instead. For example: # tmsh lis sys ntp sys ntp { timezone US/Pacific } # date Fri Apr 3 11:01:55 PDT 2015 # ssh aom date Fri Apr 3 18:01:55 UTC 2015 # tmsh lis sys ntp sys ntp { timezone Japan } # date Fri Apr 3 07:32:08 JST 2015 # ssh aom date Thu Apr 2 22:32:08 UTC 2015

Impact

Timestamps associated with events logged by the AOM may be encoded to a different time zone (UTC) from events logged by the BIG-IP/EM host system. In circumstances where AOM-generated logs are analyzed and compared with BIG-IP/EM logs, the time zone differences will have to be reconciled/accounted-for manually.

Conditions

This issue may affect the following F5 appliances which use the "AOM" type of Always-On Manager subsystem: BIG-IP 1600, 3600, 3900, 6900, 6900S, 8900, 8950, 8950S, 11000, 10050 appliances Enterprise Manager EM-4000 appliance

Workaround

In circumstances where AOM-generated logs are analyzed and compared with BIG-IP/EM logs, the time zone differences will have to be reconciled/accounted-for manually.

Fix Information
