the map is blank. Error still.

[United-Networking]

Hi,

i have Nagios Core 4.1.1 on Debian Wheezy and the new Map worked until about a month ago.

Anyway, Symptoms look just like with zurrachillo on Thu Feb 24: Map is a framed, empty square with a little menu at top left, nothing else.
Firefox 45.0.1, Vivaldi TP4 (a Chrome mod) and IE 11.162 all show the same.

The only thing that comes to mind is that Firefox updated maybe once or twice in that timeframe, which doesn't explain the other browsers.

Now, zurrachillo wrote Thu Feb 25, 2016 10:15 am,

The problem is the link because in the new versions Map and Legacy appears, if I click on map appears to me empty but if I press legacy if it works, so I modified the "side.php" to make good link.

I believe he just switched to using the old style map, which i believe does not solve the original problem.

Looking at the source, it appears to draw SVGraphics via Javascript. Shouldn't be a problem, but in 3 different browsers here and on another machine, it is.

What gives?

Did ANYTHING change at all about a month ago when this stopped working?

[United-Networking]

Hi,

yeah, as i said, my main browser, Firefox, updated once or twice in that timeframe.
Now the map doesn't work anymore:
* in Windows 8.1 or Windows 10,
* with Firefox since about v42,
* with Vivaldi TP4 (NO updates in that time frame)
* IE 10 (subject to Win. updates)
So, several platforms, several browsers, no joy, where it _did_ work before.

But - i just tried Iceweasel (a rebranded & reconf'd Firefox) v38 on Debian Testing, where the map worked!

So it's IMHO not OS-specific, but something more modern browsers do different or not any more, in the Javascript or SVG realm.
Frankly, i'm stumped.

What's the locale of your core machine?

[United-Networking]

Hi,

our Nagios Core machine has:

Code: Select all

$ locale
LANG=de_DE.UTF-8
LANGUAGE=
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER="de_DE.UTF-8"
LC_NAME="de_DE.UTF-8"
LC_ADDRESS="de_DE.UTF-8"
LC_TELEPHONE="de_DE.UTF-8"
LC_MEASUREMENT="de_DE.UTF-8"
LC_IDENTIFICATION="de_DE.UTF-8"
LC_ALL=

The Windows machines i tested browsers on are all german, too.
The Debian machine where the map works has

Code: Select all

$ locale
LANG=en_US.UTF-8
LANGUAGE=en_US:en
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

Would it be possible to change the locale of the Core machine to en_US to see if this is causing the problem? There were some issues with core being in a different locale that are going to be pushed out in the 4.1.2 update. Nagios Core 4.1.2 prerelease is on GitHub, if you want to test it for yourself.

[United-Networking]

Hi,

yes, and no. A /etc/default/locale with

Code: Select all

LANG="en_US.UTF-8"

now, and the map display remains the same as before.
In Debians Iceweasel it works, elsewhere not.

[thegaby]

Same Issue here.

[hsmith]

Can you hit F12 to pull up the console(Firefox/Chrome), and see if you notice any errors in the network tab?

[United-Networking]

Hi,

Oh yeah, that probably hit pay dirt!
Got an error after "GET map-popup.html":
