Grayed out hosts and services - process state not running

[drug]

Nagios XI 5.5.6

Under Monitoring Engine the "process state" reports "not running". I've restarted npcd and ndo2db and nagios. All hosts and services are "grayed" out. When clicking on any host or service, only "Object Does Not Exist" is returned.

This all began shortly after running repair_databases.sh (the MySQL server is running on another system).

How do we get this working?

Thanks.

The issue was resolved after:

Code: Select all

systemctl stop ndo2db
systemctl stop nagios
rm /usr/local/nagios/var/retention.dat
systemctl start ndo2db
systemctl start nagios

Hi, @drug. Thanks for the update. I suspect it was the NDO2db issue that got resolved after you restarted it.
Is your XI fully functional at this point? Do you have any further questions before I lock the thread?
