Hi All,
I have on two CentOS 7 hosts installed Graylog (GL) cluster and I have Mongo cluster running on both boxes,
and elasticsearch (ES) running on one of hosts.
All components are systemd services.
When reboot one host I see ES and Mongo restarted but not GL.
from logs it looks like GL starts first and can not connect to mongo and after 30 sec GL service stops.
But shouldn’t it be that after say every 30 seconds GL tries to reconnect and does it for say 10 times or forever
until mongogo service is available?
