Nagios XI - Last Check Time Not Updating

[scharft]

Hi,

since "2020-11-21 03:05:03" the last check result doesn't update only in Nagiosxi, in Nagios Core everything is fine.
Database repair script and reboot doesn't fix it.

e.g. https://support.nagios.com/kb/article.p ... %20checks).
https://assets.nagios.com/downloads/nag ... ptions.pdf
doesn't help.

Any Ideas?

Hi @scharft,

When did this start happening? After an upgrade?

It looks like a ndo (database component) issue. If you can send me the system profile, I can review the logs and settings to double check.

Benjamin

To send us your system profile.
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button

Hi Benjamin,

this happening started last Saturday night, date & tiime you can see in the screenshot ~ 03:00:00 for all of the checks.
We upgraded Nagios XI to Version 5.7.5 after this problem, we hoped this will fix it.

The profile is attached.

thank you

Attached to the post is an updated NDO3 broker.
Copy the mod-master.tar.gz file to the XI server and run the following to compile, install it and to restart nagios.

Code: Select all

tar xvfz ndo-master.tar.gz
cd ndo-master
./configure
make all
make install

Save the file and then restart nagios.

Code: Select all

service nagios restart

See if this helps the issue you are having.

Hi,

thank you.
the error has been fixed.
Can you please explain what was the problem?

There was a bug in the older NDO3 broker that would not update the checks in the MYSQL database which the XI interface uses to display the data.
The new broker fixed that.

[scharft]

ok, thank you.
Can you check if we have an error in the ndo on our new server?
After applying a new configuration we have to wait ~10 - 30 minutes until the last check result updates the values.

This is shown => 18598d 13h 46m 31s 0/0 1970-01-01 00:00:01 No check results for service yet.

I am going to need to see the nagios.log file from the server to determine if there are any errors.

Restart nagios by running this.

Code: Select all

systemctl restart nagios

Wait for an hour and post the /usr/local/nagios/var/nagios.log file so I can view it.
