How I can change monitor settings?

These are standard monitor parameters that could be set when creating a new monitor or modified on an existing monitor. Are you familiar with tmsh commands and operation?

create ltm monitor [options...]

modify ltm monitor [options...]

This TMSH command reference is for 11.1, but the commands should be similar and you can find the reference for your version on . Check out the section in the reference titled "LTM Monitor Module components".

Is there a specific monitor or options you are having trouble with?

as Ed said in the first rely it's in the TMSH manual. Below is extract for https monitor

cheers
