Hi I upgraded my NagiosXI test environment from 5.6.14 to 5.7.3, however in the nagiosXI console the status of the hosts and services stay pending.

services_pending.JPG

In NagiosXI I see the Last Check date of services and hosts 1970-01-01 00:00:01

In NagiosCore I do see the services being updated. I also see that gearman is handling the checks.
I also see that events are being handled.

Some research in the database shows:
I selected the hostcheck of a random host and the hoststatus of this same host.
the hostcheck shows the host check is succesful, however the hoststatus is pendng with dates at 1970-01-01 00:00:01

Code: Select all

MariaDB [nagios]> select * from nagios_hostchecks where host_object_id = '88950' ;

Hi!

We have found an issue with check results not being updated if there is a crashed database table, so I would go ahead and run the repair script.

Code: Select all

/usr/local/nagiosxi/scripts/repair_databases.sh

Let us know the results. If the issue persists, please attach or PM a System Profile tarball? You can download it if you go to Admin (top of screen), then click System Config (left menu) => System Profile, then click Download Profile.

Thank you.

The reason the service checks are in a pending state is because NDOUtils is in a state where it can't make updates to the database.

The recommended course of action is to downgrade NDOUtils to a previous version.

DOWNGRADE NDO WITH OFFLOADED DB

Code: Select all

service nagios stop
cd /tmp
rm -rf /tmp/nagiosxi
wget https://assets.nagios.com/downloads/nagiosxi/5/xi-5.6.14.tar.gz
tar zxf xi-5.6.14.tar.gz
cd /tmp/nagiosxi

If you have an offloaded DB you'll need to do these things:

Edit /tmp/nagiosxi/xi-sys.cfg and update 'mysqlpass' value.
Edit /tmp/nagiosxi/subcomponents/ndoutils/mods/cfg/ndo2db.cfg and update 'db_host', 'db_user', and 'db_pass' values.
Edit /tmp/nagiosxi/subcomponents/ndoutils/install and /tmp/nagiosxi/subcomponents/ndoutils/post-install to update all calls to mysql to include -h <db_ip>

Then continue as normal.

Code: Select all

cd /tmp/nagiosxi/subcomponents/ndoutils
./install
systemctl enable ndo2db
service ndo2db start

Then edit your /usr/local/nagios/etc/nagios.cfg and make sure this line is uncommented:

Code: Select all

broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg

Make sure this line is commented:

Code: Select all

#broker_module=/usr/local/nagios/bin/ndo.so /usr/local/nagios/etc/ndo.cfg

Then start the nagios service:

Code: Select all

systemctl start nagios
