Not seeing anything that should throw off a JSON parser like that, and it looks pretty similar to mine. I'm going to have to show this to our Core dev and see what he has to say about it.

The record dumps you provided were for "query": "programstatus", which is unlikely to cause any problem. You should have some other requests to either statusjson.cgi or objectjson.cgi. One or more of them will have the json parse error you showed earlier. That's the one we need to take a look at.

Hi,

right, i'll come to that. You're right, there is one from objectjson.cgi as well:

https://cloud.united-networking.eu/nagi ... y=hostlist

As you can see, this asks for a complete hosts enumeration, which covers several hundred entities and is somewhat sensitive, as it includes our clients' hosts, too. To me, it looks completely normal, though. An anonymized sample:

I believe nothing much in the way of error causes can be gleaned from that.

But i noted something about angular.min.js, probably also relevant, from the Console Error tab (End line references moved above code lines for clarity):

And yes, i felt moved to check on owner and permissions:
They were nagios:nagios and 664, respectively, for all of the files under /nagios and /nagios/js.

We will need to do some more digging into this, and will get back to you within the next 24 hours.

Ok, as I suspected, here's the problem. I added line numbers to the JSON object. As the error message says, go to line 33, column 29.

Code: Select all

        "check_interval": 5,00,
....+....1....+....2....+....3

That check_interval number is Five Point Zero Zero. The JSON parser expects numbers to be in 5.00 with a decimal point. The parser saw the comma and expected another object, but it just found 00.

Did you ever put in the fix I proposed in my message from 2016-Apr-14? That fix should be exactly what this needs. It will cause floating-point numbers to be printed in the "correct" format.

Posted: **Fri Apr 22, 2016 2:57 am**

Hi,

...meaning, in the format that angular.min.js can stomach.

Yes you were apparently right with your proposal on Apr 14. I will go and do that ASAP.

If this remedies the problem, will there be a bugfix release?

Posted: **Fri Apr 22, 2016 8:46 am**

Hi,

a colleague (for whom the map works) gave me the inspiration for a less painful solution than recompiling and replacing our otherwise working Nagios installation:

In Firefox 45.0.1 (and probably earlier as well), there's a Settings > Content > Language > Choose preferred languages for web page display. This is translated from german, so probably not necessary the same as in an english Firefox.
The following dialogue window listed German, English (US), English.
In about:config, this means changing intl.accept_languages from de,en-US,en to en-US.

I removed all but English (US), [OK]ed that and re-opened that objectjson.cgi list. Lo and behold, the numbers now had a decimal full stop. And also, the Nagios map now works again. Yay!

Since i have no pressing need to read english web pages in german, this means my problem is SOLVED, IMHO.

Posted: **Fri Apr 22, 2016 8:56 am**

Great! And yes, the fix is in the code for the next release.

I'm happy it's working for you now!
