CirrusMonitor response time
CirrusThe timeout is using the default 5 seconds. The customer wants me to make the timeout lower, my concern is that I am going to flood there logs with any timeout shorter and was wondering if there was a different setting that can be used.

Like I said, if monitor is failing even on the final attempt, only then it will mark it down. And once it gets a positive response on the 1st attempt, it marks it up.
Here's the F5 explanation:
BIG-IP LTM monitors
- At regular intervals, the bigd process sends a request to each monitored object and evaluates the response.
- By default, BIG-IP LTM monitors use a 3:1 timeout:interval ratio.
- If the bigd process receives at least one correct monitor response during the timeout interval, the object is considered Available.
- If the bigd process does not receive at least one correct monitor response during the timeout interval, the object is considered Unavailable.
Regarding your issue, its a jsp file, similar to other asp or php pages but containing javacode. If your requirement is to mark it down when its really down for 5 seconds, then your timeout should be 5 seconds. You can keep your interval to 5sec also instead of 1sec. But F5 recommends 3x+1 timeout value. Hope this should work.

Thanx Jaikumar
I will relay message to customer and work on how we can customize the monitor as per there requirements.
