    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,

Could you review in the Central Manager "Main for you" the path /var/log/ltm, the logs structure in the Big-IQ looks in some cases as in Big-IP devices.

Hi thanks for for your input.

In /var/log there is many logfiles, deamon, maillog, cron, restjavad etc. And as you said there is also ltm. Do you know what kind of event i would be looking for in that file? I'm not sure i can orchestrate a failover to try it out.

Also, do you happen to know if there is any documentation on this?

Thanks!
