[dev.icinga.com #8587] Clicking small perf graph opens wrong page about icingaweb2-module-pnp HOT 11 CLOSED

Hi Mathias,

what is your base Icinga Web 2 url? Are you running it at the root (/) of a dedicated domain? If so, you must configure PNP4Nagios to run at an URL different from /pnp4nagios as it would collide with /pnp4nagios from this Icinga Web 2 module.

Cheers,
Thomas

Hi Thomas,

Thanks for your quick reply!

I was indeed running Icingaweb2 in the root of my domain. I changed my apache config so that it is now running in the default location (/icingaweb2).
Unfortunately, this did not solve my issue. The small graphs are still displayed, but clicking them returns a "Server error: Service not found" error (I did change the file I mentioned above back to default).

If I understand correctly from your explanation, the module should be accessible on /icingaweb2/pnp4nagios. However, this is not the case (This results in a "Page not found" error).

Best regards,
Mathias

That's partially correct. The module occupies /icingaweb2/pnp4nagios in your current configuration, but it has no own "base url" as there is nothing "generic" it could show. That explains this issue:

However, this is not the case (This results in a "Page not found" error).

When you click on a small icon, this should open a link like this one:

/icingaweb2/pnp4nagios?host=localhost&srv=ping&view=3

That URL builds nothing but a very simple iFrame and will load the "real" PNP4Nagios url as follows:

/pnp4nagios/graph?host=localhost&srv=ping&view=3

Works fine for me - but this does by no way mean that we are bug-free ;) So please, dig deeper we'll find a solution for you.

Thanks for your feedback!

Clicking the small graph, it does indeed point to a url like

/icingaweb2/pnp4nagios?host=localhost&srv=ping&view=3

However, the page opened in the iFrame does not redirect to

/pnp4nagios/graph?host=localhost&srv=ping&view=3

but rather looks like this:

When I open this url directly, this is the "Page not found" error I was talking about.

Opening the URL /pnp4nagios/graph... directly does work and points to the working pnp4nagios page.

Best regards,
Mathias

Could you please open such link, show the HTML source code in the browser, search for id="col1" and paste me it's HTML? Should be just a div and an iFrame.

Aha! Thanks for your insanely fast reply :D it was redirecting to a wrong url.
When I was looking for a fix for the issue I had earlier, I made some changes in IndexController.php as well I forgot about. My bad..

After changing this back, everything does work as expected. Thanks again for your feedback!

If I would like to run icinga2 in the root of my domain, and have to change the default pnp4nagios url, do I also have to point the module to the new pnp4nagios url somehow?

NP, glad that it works!

Correct. Please find instructions for how to tell the module about your new URL at /icingaweb2/pnp4nagios/config :)

Correct. Please find instructions for how to tell the module about your new URL at /icingaweb2/pnp4nagios/config :)
Using the information on this page, I created a config file in /etc/icingaweb2/modules/pnp4nagios/config.ini containing the following:

[pnp4nagios]
config_dir = /etc/pnp4nagios
base_url = /p4n

I also changed my Icinga web 2 base url back to / and the base url for pnp4nagios to /p4n.
Both urls work separately, however the iframe still tries to open /pnp4nagios/graph?host...

It seems like the IndexController is not using the right base url. After changing

$baseUrl = rtrim($this->Config()->get('pnp4nagios', 'base_url', '/pnp4nagios'), '/');

to the following (based on baseUrl used in the Grapher class):

$cfg = $this->Config()->module('pnp4nagios')->getSection('pnp4nagios');
$baseUrl = rtrim($cfg->get('base_url', '/pnp4nagios'), '/');

It does work as expected.

No idea if this is caused by an error on my side or not..?

Mathias
