DOWN status of application still show the UP status in eureka page?

[kenttanl]

Hi ,

I encountered a problem, the eureka page is shown like this:

Application	AMIs	Availability Zones	Status
GATEWAY	n/a (2)	(2)	UP (2) - WCMIS208:GateWay:10020 , WCMIS209:GateWay:10020

but 'GATEWAY' has been closed on 'WCMIS208', so its status should be 'DOWN' or not displayed.

Although this does not affect the normal use, but I still want to where is the problem? thank you all

What do you mean it has been closed? Is Eureka in "self-preservation mode"? If it is it won't evict any down instances.

@ryanjbaxter Thanks, you are right, and I saw this:

EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.

So, can I manually remove it? Thanks again

It is not recommended but you can disable self preservation mode by setting eureka.server.enableSelfPreservation to false
