HTTP timeouts help

Hi,     Can anyone tell me what the default threshold for HTTP monitoring is please? Or, where can I check what it is set to?     I've created a HTTP monitor using the default in...

I'm seeing the same with GTM 10.1.

 

 

Timeouts for custom monitor are default: 30 sec interval, 120 sec timeout, 5 sec probe-interval.

 

 

This monitor is configured to probe a host that is not reachable at all.

 

 

T0 = when I enable the host, which is a virtual server.

 

 

tcpdump shows a syn go out at T0, then at T0+5sec, /var/log/gtm shows the virtual server go from blue to red.

 

 

So what gives? Seems like only the Interval and Probe-Timout values are actually referenced.

 

 

"timeout" is never used at all, from what I'm seeing.

 

 

 

Another bit of info:

 

I adjusted both up and downward the interval and probe-timeout values in my custom http monitor. Neither change actually has an impact on the probing of this test virtual server. Tcpdump shows that probes always occur at 30 seconds, and /var/log/gtm continues to show the VS turns red at T0+5sec.

 

 

Any thoughts?

 

 

thanks much!
