I'm seeing this error over and over, could you shed some light on this issue?

That's an old component that shouldn't exist on your system (it's not even downloadable anymore), please run this command to remove the command and it will remove that message, it will not impact your system:

Code: Select all

rm -rf /usr/local/nagiosxi/html/includes/components/nagiosim

Let's see if you have the old active_directory or ldapauth components, those shouldn't exist either (it's a single component now called ldap_ad_integration):

Code: Select all

ls -l /usr/local/nagiosxi/html/includes/components/

[scheived]

Shows you how long we've been using nagios.

I removed the nagiosim and no longer see error.

I tried deleting ldap_ad_integration but could no longer log in. We are using ladp and have servers configured under Admin, LDAP/AD Integration.
This has been working fine, but Is there another preferred way we should be doing ldap login?

*edit, I mean to say I could no longer log in after deleting active_directory or ldapauth

[ssax]

You'll need to put the ldapauth and active_directory ones back (see attached for all 3 if you need), you can do this in Admin > Manage Components and upload the zip files there.

Then you'll need to follow this process:

First, set nagiosadmin to a local account (if it isn't already) and logout/log back into the system with it.

Then, disable active directory authentication in Admin > Manage Components > Active Directory > Settings, double check Admin > Manage Components > LDAP Auth > Settings is disabled as well.

Then setup the new component (copying the info from the old) in Admin > LDAP / AD Integration.

See here as well if you have issues:

https://support.nagios.com/kb/article/a ... n-600.html

Once you've done that and tested login functionality you can run these commands to get rid of the old components:

Code: Select all

rm -rf /usr/local/nagiosxi/html/includes/components/active_directory
rm -rf /usr/local/nagiosxi/html/includes/components/ldapauth

Having the old ones and the new ones on the same system can cause slowness issues which is why this needs to be done to clean it up after you get the new one working.

Worked great thanks so much.

Hi,

Worked great thanks so much.

Great. Did you have any other questions or may we close this thread?

Just one question about configurations upgraded over the years, I see there is documentation for converting from PostgreSQL to MariaDB. Is there any preference for Nagios to convert sooner than later or at all?

[benjaminsmith]

Hi @scheived,

We continue to support both postgres or MySQL for the nagiosxi database, so it's safe to leave it as is.

If you would like to migrate this to MySQL, then I would recommend setting up a test instance and follow the steps in the doc. Most customers are able to migrate this over without much trouble.

Let us know if you have any other questions.

Benjamin
