    Hi,

    Without documentation, I recommend you open a support case with F5 level 4 " how-to ", because I am almost sure that these events are in var/log/ltm, but it's better if support confirms it if you can´t perform a failover.

    and the other question, the answer is Yes, Big-IQ is based on TMOS, and the OS is similar to Big-IP that runs TMOS inside too, you can try this command without any wrong behavior tmsh show /cm failover-status.

Hi,

If you made the failover this week, you probably have in the system files like ltm1, ltm2, ltm3 etc. these correspond to each day, so you can explore and research words like "failover" , "Standby", "HA".

Additional, you can refer to the LTM documentation because for Big-IQ I never saw something relating to logs files:
