Hi,

as far as I'm concerned, I log some information in F5 /var/log/ltm when I have to investigate issues. If you want to store logs you can send logs directly to the remote syslog using HSL without storing them locally.

So for me Persistent logs are not important, unless you want to investigate because of unexpected behavior. So you can remove logs in irule.

For this, just add a in front of all command beginin with 

log local0.
:

 log local0. "bla bla bla"

If you need help to deploy HSL, keep me update. for more info:
