Nimbostratusdynamic ratio
we have several application servers and load balancing using the observed mode.We have also a montiroing system which works fine.And now thinking to move towards dynamic ratio load balancing.
And for we are not sure about the method mfor dynamic ratio;
1)is it best if we use wmi for windows and simulate the f5isapi.dll by a servlet on java app. servers, but it may be expensive to use server threads
2)using an external type monitor on F5 and get the data from the monitoring system and set the ratio by scripting, but it may be expensive for F5 resources
3)on a 3rd party server , we can deploy a servlet and get the data from the monitoring and set it on F5 via icontrol., again is it too expensive to execute such a web service call on F5 every 60 seconds,,
Finally is it possible configure fallback monitor on dynamic ratio load balancing, in this case if the load configuring monitor stops, what would be the ratio,the last set values?

What about using SNMP to have LTM poll the pool members for CPU, memory, etc usage?Finally is it possible configure fallback monitor on dynamic ratio load balancing, in this case if the load configuring monitor stops, what would be the ratio,the last set values?
I don't think so, though I'm not sure what happens if LTM can't reach the devices to poll them. You might try testing this. You could also open a case with F5 Support to ask about this and/or ask to have new functionality created to handle the scenario better.

yuce_sungur_100What we need is to monitor the thread pool of application server so any Os resource is not our exact health indicator.
I will try fallback monitor for dynamic ratio
