I have observed a huge difference in the display of screens in NagiosXI for non-Admin users.
As an examle, simple screens such as Host Status Detail or Service Status Detail are taking approx 60 seconds to display. This has been tested on both Firefox & Chrome browsers.
The same pages using the same browsers on the same desktop take 3 seconds to display for an Admin user.

When the non-Admin user selects one of the Status Details Page, the top part of the screen (up to the four icons -view status/notifications/history/availability) displays immediately, the rest of the screen (from the tabs onwards) is what takes 1minute to display.

System profile follows:

Code: Select all

Fred,
Can you have a look at this forum post and see if any of this helps:

https://support.nagios.com/forum/viewto ... 74#p188567

If possible I would like to see if you can access XI from a machine in the same subnet as the XI server and see if the problem occurs.

Posted: **Fri Jul 29, 2016 3:43 am**

Thanks Troy - it might be a task to get access to another machine in that subnet.
I had a quick look at the forum link and it looks like what I am experiencing - however there is no reolution listed?
Personally, I can't see it being a network/firewall/dns issue as exactly the same desktop and browser are used to login as both a Nagios user & Nagios Admin user.

The user account has "See all objects" & "Can access advanced features" selected
I did some further testing as per the OP and can confirm that the screen displayed normally when I unticked "Can access advanced features".
When I tick it again, the screen delay comes back.

regards... Fred

When the "admin" views the data, all of the objects are shown right away (there are no checks in place to verify that the user is actually "authorized" to view the objects). If this is a "non-admin" user, there are checks in place. I would imagine, if you had a very large environment, it would take some time to go through all objects. How many hosts/services are you monitoring?

FYI, I am not able to recreate the issue but I am not monitoring too many hosts/services. In any case, I am going to discuss the issue with our developers to see if they can provide you with a possible solution.

I am having the exact same issue just starting today. I am finding even going to services from core config does not load. Is something going on? even for admin users.

@sujitt
This may/may not be the same issue. Please start your own (separate) thread. Explain in details the issue that you are having. Show relevant logs, screenshots, etc.

@Fred Kroeger
I am sorry - somehow I failed to see the number of hosts/services that you are monitoring. They are not too many. It is strange that it takes 60 sec or more to load the page.

Let's try the following:

1. Open the "/usr/local/nagiosxi/html/includes/utils-objects.inc.php" file in a text editor, and change the line below the " is_authorized_for_object_id" function (around line 963) from this:

Code: Select all

$debug = false;

to this:

Code: Select all

$debug = true;

2. Log in as a "non-admin" user, click on a host or a service under Host/Service Detail page, and show us a screenshot.

I logged in as normal user and it works fine. It looks like when I login as admin user I have the service detail screen not loading at all.

As @lmiltchev mentioned, please open a separate thread for your issue as another customer opened this one and we need to keep them separate.

Sorry for the delay - been away for a couple of days.
Good & bad news first. I have tested this on the test Nagios instance at this site and while it is monitoring fewer servers, there doesn't appear to be any difference with the speed of the screen displays. I have now tested this at another Site and didn't see any difference either. So it would appear that the problems I am having are restricted to just the one Nagios instance. (They are all set-up much the same and are all using the same version of NagiosXI)

With Advanced Features turned on (60 sec delay in displaying screen)

With Advanced features turned off (no delay)

Fred,

For further debugging, please fire up your text editor of choice and open the file /html/includes/components/xicore/ajaxhelpers-hoststatus.inc.php. In the function xicore_ajax_get_host_status_quick_actions_html (around line 562) there is a line:

Code: Select all

$auth_command = is_authorized_for_host_command(0, $hostname);

Comment that line out, and then directly underneath it add:

Code: Select all

$auth_command = true;

So, when finished it should look like this:

Code: Select all

//$auth_command = is_authorized_for_host_command(0, $hostname);
$auth_command = true;

Now, try viewing the Host Status pages again with 'Advanced Features' turned on and let us know if there is any speed difference.

Thanks.
