Problem Description
In some pages of XI you may come across empty screens, such as no configuration wizards appearing under the Configure menu.
When plugins, components or wizards are not installed through the proper menus, this creates problems in Nagios XI, such as "wiping out" all wizards, so they can not be viewed in the Web interface, blank pages in the Web browser and other weird behaviors.
The proper way is:
Download the dashlet, component or wizard you need to install
Go to the Admin menu and then select the proper sub-menu from the left panel under the System Extensions:
For Dashlets: Manage Dashlets > Browse (select your plugin installation file) > Open > Upload Dashlet
For Components: Manage Components > Browse (select your component installation file) > Open > Upload Component
For Wizards: Manage Config Wizards > Browse (select your wizard installation file) > Open > Upload Wizard
Note: Don't unzip the installation file prior to selecting it through "Browse".
Also, don't rename the installation files. This will cause the installation to fail. The name of the file should be: "somename".zip. If you had a previous copy of the file and you download it again, your new file will be named "somename"(1).zip, which will not work.
If you already made a mistake and erroneously installed a component in place of the wizard or vice versa, here is what you should do:
Remove the problematic component/wizard by running in terminal as a root:
rm -rf /usr/local/nagiosxi/html/includes/components/somedashlet
rm -rf /usr/local/nagiosxi/html/includes/components/somecomponent
rm -rf /usr/local/nagiosxi/html/includes/configwizards/somewizard
Try installing the component/wizard again.
If you have blank pages in the web browser, this usually means there is a PHP error. Run:
tail /var/log/httpd/error_log
right after loading that page to see what the errors are. If you are unsure how to resolve the problem please contact support.
Sometimes, when you try to install a plugin you may receive an error message:
The following error message is produced:
Plugin could not be installed - directory permissions may be incorrect
In order to check the permissions of your "libexec" directory, run in terminal:
ls -l /usr/local/nagios
The owner of "libexec" directory should be nagios:nagios and the permissions should be set to 775 (drwxrwxr-x). If this is not what you have, run in terminal:
chmod 775 /usr/local/nagios/libexec
chown nagios:nagios /usr/local/nagios/libexec
Then attempt to upload the plugin again
