GTM Failover to other datecenter (other pool)

Folks,

 

 

we have a GTM and one of wide ip configured for last resort pool , with Manual resume.

 

whenever parent pool goes down or GTM sense issue in between GTM and LTM _1 it will failover d trafiic to last resort pool i.e. LTM_2 (in other datacenter).

 

in this case we have to manual enable pool at LTM_1. after which we start finding root cause of failover, we didn't find any issue in the network.. .below r my question:

 

 

1) what could be d possible reason for failover?

 

2) if this happen due to any network glitch between GTM & LTM, can we set any time interval on GTM which GTM keep monitoring LTM.

 

 

our alert system didnt showed network issue for such instance.

 

 

 

Thanks in Advance,

    I have seen issues in the past where a pool appears like it is up and working but will drop at times. When I looked at config there was a health monitor on the pool's for the GTM. If this is the case remove health monitor. LTM VS status is determined by iquery.
