yes , If you configure " Availability Requirement " to "ALL" and one of your assigned monitors fails " the whole node will be marked down >>> this is for Nodes level.
- If you did this on Pool Level , and " Availability Requirement " to "ALL" and one of your assigned monitors fails " the whole Pool will be marked down and wouldn’t recieve anymore traffic and this will appeare that " the impacted virtual server will reset the traffic that destinated to with a reason of ( no pool_members available ) in reset packets "

yes, so that wouldn´t work for us. As one one of the monitors should only have an impact if a string is read.. not on a timeoout or anything else, only string.

okay , you have one pool contains , two members.
> Do you assign both of monitors on pool Level , or on Nodes "members" level ?
> Do you loadbalance traffic to both of them ? , also maybe what makes the monitor down " All servers Marked down " the server owner or what ever the person who change the "File" that you monitor on tampers this file on both of servers so you see both of them marked down not only one of them .
> your Request is :
you want to detect the change of this file , or a way to restrict this file on server and not make anyone to tamper it.
Specifiy your request more

I’m looking forward to your reply.

I dont think you understand the question. The file is not the issue, its how to limit the monitor to only act on file content and not on timeout or anything else.

kimhenriksen ,
you can not disable the Timeout.
you can put a very large value instead of "16" seconds (default) , you can put "86400" this value.
that is mean your monitor will not be marked down for a full day "86400" seconds , it means almost you disabled this timeout.
I do not why you want to do that really ?
