manumoh@johnsom Hey, I was trying to perform a controlled failover by setting a large value to health manager heartbeat_timeout , its works as expected but one strange thing I noticed . I accidentally set the  heartbeat_timeout to 10 instead of default value which is 60, now all lbs are getting failedover  continuously. If I set the value to 60 things are all fine. Any thoughts on this  ?16:30
johnsomYeah, that would be expected with the default settings.16:31
johnsomOne second16:32
johnsommanumoh The default heart beat interval is 10 seconds. So if the heart beat timeout is also 10 seconds, the health manager will think that all of the amphora are not responding. By default, we expect 60 seconds for the timeout to allow the amphora six tries to send a heart beat packet to one of the controllers.16:35
manumohthe default heartbeat_timeout is 60 sec as per documentation https://docs.openstack.org/octavia/latest/configuration/configref.html#health-manager16:37
