Nagios Graph Explorer not working after upgrade to 2.8c

[WillemDH]

Hello,

All my created dashboards no longer work since I upgraded to 2.8c. They seems to still exist on the dasboard, but they are blank... Also when I go to Graph Explorer, Top Alerts, Host Health and Service Health seems to work, but Scalable Performance graph, Time Stacked Performance Graph and Multistacked Performance Graph is loading eternally and does not show any graphs.

Please advice.

Willem

When I tail /var/log/httpd/error_log, it get the following errors after opening a dashboard with Grap Explorer dashlets on it:

Code: Select all

[Mon Jan 27 11:26:05 2014] [error] [client xx.xx.xx.xx] File does not exist: /usr/local/nagiosxi/html/http:, referer: http://nagios/nagiosxi//dashboards/dashboard.php?id=trl0bgfp

I tried

Code: Select all

service npcd restart

and shift reload web page, but still same problem..

This isue is quite urgent as we have several endusers who have no dashlets on their created dashboards anymore.

http does not exist apparently...

Code: Select all

It seem I have two problems.

1) The Grap Explorer does not work on Internet Explorer 11 and Firefox 26.0, but it does seem to load on Chrome

2) Our dashboards are not working on any browser and the httpd errorlog shows

Code: Select all

[Mon Jan 27 11:26:05 2014] [error] [client xx.xx.xx.xx] File does not exist: /usr/local/nagiosxi/html/http:, referer: http://nagios/nagiosxi//dashboards/dashboard.php?id=trl0bgfp

when browsing to a dashboard with highcharts on it.

[WillemDH]

Ok problem 1) can be solved by emptying temporay Internet Files.
I've been testing for problem 2) When I add a new dashlet to a dashboard it does seem to show. Does this mean I will have to add all my dashlets again from scratch? Please say no.....

[WillemDH]

Just wanted to say the new dashlet system and graph explorer system is very nice, I did found a minor issue with the order of services added to a multistacked graph. made a usability issue for it: http://tracker.nagios.com/view.php?id=494

So any news on the blank dashlets on my dashboards and the missing file /usr/local/nagiosxi/html/http?

You upgraded from 2012R2.7, correct? Did you install from source or used one of our VMs? 32- or 64-bit? We are having difficulties recreating the issue in house, so the more info we get, the getter. What kind a dashlets did you create? Anything specific?

[WillemDH]

Hello,

Yes I upgraded from 2012R2.7. I installed following the documentation competely (latest tar). The created dashlets are normal CPU, memory, SQL related perf data, pings rta and pl etc.

There is not one dashlet working from before the 2.8c update. They are all still there, but completely blank. The only thing I can do is delete them, pin and unpin and move them or change size, but they stay blank.

The only thing non default I changed in the past was changeing the default width and height, seehttp://support.nagios.com/forum/viewtop ... lit=+graph for information.

As I said when I add new graphs they are displayed nicely. The multistacked graphs are just perfect. Very nice work on that.

Did some new tests. When I go to a dashboard with 'the old dashlets' on I get the

When I go to a dashboard with new (multistacked) dashlets on, I get:

But I guess these errors are some other bug.

I was able to recreate the issue on one of my test boxes. It is a bug, which should be fixed in the next release. Meanwhile, you can try the following patch (workaround). Make a backup of your "dashlet.inc.php" file:

Code: Select all

cd /usr/local/nagiosxi/html/includes/components/graphexplorer
cp -p dashlet.inc.php dashlet.inc.php.backup

Open the "dashlet.inc.php" in a text editor, and file the following line (around line 20):

Code: Select all

$url = get_base_url().$url;

Change it, so it is going to look like this:

Code: Select all

if (strpos($url,"://") ===false){
$url = get_base_url().$url;
}

Save and exit. Let me know if this brings your old dashlets to life.

[WillemDH]

Yes! They are all back. I checked the httpd error log and no errors reported for the 'old' dashlets. Thanks you.
