How to analysis qkview

The very best way, in my opinion, is with iHealth:

https://ihealth.f5.com/qkview-analyzer/

In lieu of that, a qkview is essentially a tarball of the relevant portions of the filesystem (config directory, logs, etc.), so you can break it open and analyze it yourself (albeit manually).

Could you please explain How to analysis qkview ? for device reboot issue, tmm restarting issue.

Go to https://ihealth.f5.com/qkview-analyzer/, log in with your support account, and then upload the qkview. iHealth will expand and analyze the qkview for you and generate a report of high/medium/low issues.

If that is not an option, open a support case.

for device reboot issue, tmm restarting issue.

looking for log prior to the time tmm restarted. as Kevin mentioned, you may open a support case to get assistance from support team. qkview/ihealth, log tarball (if log is truncated in qkview), core and its md5 checksum (if had) are required.
