Hello,
I have one Nagios XI instance which has stopped adding new hosts via the API. However, adding them manually in the web UI works fine, and after manually adding them the API works just fine to remove them.

The API results show success, whether it's a new target or trying to add a target which already exists:

Code: Select all

success
-------
Added <new host name> to the system. Config imported but not yet applied.
Apply config command has been sent to the backend.

I found another topic describing a similar problem, which led me to finding out that STRICT_TRANS_TABLES were enabled. I disabled them by following this KB article, but that didn't seem to help.

This is on CentOS Stream 9 (x64), Nagios XI 2024R1.1.2. I am also having trouble trying to upgrade this system, which I'll open another topic for.

Hey @cbeattie-unitrends

Sorry you are having this issue. Could you post what CLI command you are running to hit the api to try to add a new host? First line of thought is to check all the flags to make sure everything is correct. The response makes me think that the flag to apply the config isnt being sent. That being said if its not, does it still not show up if you apply config in the web gui?

Here's the code:

Code: Select all

$irm = @{
	Method      = "Post"
	Uri         = "$($nagios.url)config/host?apikey=$($nagios.password)"
	Body        = "host_name=$target&address=$($dns.Name)&use=generic-host&hostgroups=replication-targets&force=1"
	ErrorAction = 'Stop'
}
try {
	Invoke-RestMethod @irm
}

That particular bit doesn't use the &applyconfig=1 because the script it is part of calls the applyconfig URL ("$($nagios.url)system/applyconfig?apikey=$($nagios.password)") later in case there are multiple hosts being added to Nagios (which is where "Apply config command has been sent to the backend." is coming from. However, if I update the first URL to include &applyconfig=1, the output is:

Code: Select all

success
-------
Added <new host name> to the system. Config applied, Nagios Core was restarted.

But the added host still does not show up.

If I do not apply configs via either URL, there is no notification in the web UI that there is a configuration change awaiting application.

This script works just fine adding hosts to other Nagios instances and has successfully added hosts to this instance in the past, so I'm fairly certain the problem exists only in this one Nagios XI instance.

To add some more to it, as far as I can tell, the database tables are in good shape:

Code: Select all

[root@nagios ~]# db_user='root'; db_host='localhost'; db_pass=$(/usr/local/nagiosxi/scripts/get_mysql_passwords.sh | awk 'NR==1 {print $4}')
[root@nagios ~]# mysqlcheck --force --check --host=${db_host} --user=${db_user} --password=${db_pass} --all-databases

1. Check Nagios XI Configuration
Ensure that Nagios XI's configuration files are correctly set up and that there are no issues with how configurations are applied. Sometimes, issues can arise if the configuration files are not being updated or if there are syntax errors.

Review Nagios XI Logs: Check the logs for any errors or warnings related to configuration changes.

Log file locations:
Nagios XI Logs: /usr/local/nagiosxi/var/ (look for audit.log or other relevant logs)
Nagios Core Logs: /usr/local/nagios/var/ (e.g., nagios.log, debug.log)
Configuration Files: Ensure that the configuration files in /usr/local/nagios/etc/objects/ (or other directories where your objects are stored) are being updated as expected.

2. Verify API and Configuration Import
When you add a hostslope via the API, it should trigger a configuration import, and then a configuration apply.

Manual Apply Config: Try manually applying the configuration from the Nagios XI web UI after adding a host via the API to see if it then appears correctly.

API Success Message: The success message you receive from the API indicates that the configuration import process was triggered. However, confirm that this process is completing successfully. Check the nagiosxi log for any import-related errors.
