Nagios Support Forum

I'm not sure how many graphing tools you looked at, but http://oss.oetiker.ch/rrdtool/ seems to be releasing more often...or at least more recently. It might be worth a look if you are going to start over.

This is not to say we can't continue to help with the nagiosgraph issue. It's just that since it is not our product, it is hard for us to support.

That's understood. After all it clearly isn't a problem with Nagios itself.
Looking at other solutions might be worth a try. I have a dislike for things that break silently.

Could you PM me the HTML output of the page showing the error? If there's nothing that needs to be scrubbed, you could just post it in the thread (or scrub it).

This is a screenshot of a typical page (note the blank spaces in the selector box in the upper right - apart from that, the page is working). I can only post a snippet of the file because

Your message contains 211746 characters. The maximum number of allowed characters is 60000.

This seems to be relevant: The first line calls nagiosgraph.js; in my case, the URI is http ://mymachine/nagios/nagiosgraph.js, which IS present and can be displayed in a browser when called directly.

Edit: file attached, with extension changed from .html to .txt

I poked around for weird javascript issues and the below suggestions seem to be working for people. You may already have done these things, but going back through the thread I didn't see mention of them.

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

"Remove Cookies" from sites causing problems:

Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Safe Mode (https://support.mozilla.org/en-US/kb/tr ... -safe-mode) to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Don't make any changes on the Safe mode start window.

Firefox is also on version 49 now, so maybe upgrading will help. You might also try a different browser, such as Chromium (or Chrome, or Opera or whatever).

Please let us know if any of the above solves your issue.

It's not a local issue. The problem is present with any computer, any OS, any browser. I wrote earlier that it wouldn't appear on a local machine running OpenBSD; that was wrong. It does appear there, too.

You're still on 4.1.1, right? Can you upgrade to 4.2.2? That way we can make sure if there's a bug that it still exists. Here are the instructions for upgrading: https://assets.nagios.com/downloads/nag ... ading.html

Done. The problem persists. I think it's fair to say that Nagios itself is out. Must be something else...

I mentioned rrdtool earlier in the thread, but have you looked at PNP4Nagios? I know some people that were not satisfied with nagiosgraph moved to PNP4Nagios. Of course, their use case may be different.

dwhitfield wrote:have you looked at PNP4Nagios?

For a couple of reasons (systemd, among others), I am indeed thinking about abandoning Linux altogether in favour of OpenBSD. OpenBSD 6.0 comes with PNP4Nagios, but with an apparently buggy Nagios version (4.0.8).
