Hi,

the health status is pretty stupid simple call to database:

https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/services/src/main/java/org/ovirt/engine/core/services/HealthStatus.java

https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/CheckDBConnectionQuery.java#L21

https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/dal/src/main/java/org/ovirt/engine/core/dal/dbbroker/DbConnectionUtil.java#L33

https://github.com/oVirt/ovirt-engine/blob/master/packaging/dbscripts/common_sp.sql#L421

So it should definitely not hang forever unless there is some serious issue in the engine start up or PostgreSQL database. Could you please share logs? Especially interesting would server.log and engine.log from /var/log/ovirt-engine

Hi,

I'm trying out (I think) the latest build of ovirt-engine in OST [1] and
the basic suite
fails when we do engine reconfiguration and then restart the service [2].
After restarting we wait on the health check endpoint status here [3].
This however ends with a timeout.
I tried running manually:

curl -D - http://engine/ovirt-engine/services/health

and that command also hangs forever.
In the engine log the last related entry seem to be:

2020-11-26 16:20:15,761+01 DEBUG
[org.ovirt.engine.core.utils.servlet.LocaleFilter] (default task-7) []
Incoming locale 'en-US'. Filter determined locale to be 'en-US'
2020-11-26 16:20:15,761+01 DEBUG

2020-11-26 16:20:15,761+01 DEBUG

Has anyone else also encountered that?

Regards, Marcin
