Error trying to add a second dimension if the first applies to some hosts only

[buzzdeee]

Hi,

I'm with icingaweb2 2.4.0, I get to reporting/cube, and then add a first dimension, and that works, i.e. 'hostgroup'

Then getting under "show settings" and want to add another dimension, clicking on 'Add a dimension' The selection pops up, and on selection what I want, i.e. 'os', then instead of adding the second dimension the only thing I get is the following error message:

Undefined property: stdClass::$os

When I reverse the example, i.e. first dimension 'os' and then try second dimension 'hostgroup', the first dimension for the 'os' works, but then on the second dimension I get similar error message:

Undefined property: stdClass::$hostgroup

Running the module from git commit: 3107867c9aeb5c0df08f29d2489089d0e267e854

That's strange... are you using PostgreSQL or MySQL? And in case you get a full stack trace: could you please share the full output?

[mateusz-gozdek-sociomantic]

This is also happening to me. I think this is happening when some hosts don't have specific variable defined.

Here is the stacktrace:

Not tested steps to reproduce: define two hosts:

object Host "foo" {
  var.foo = "foo"
  var.bar = "bar"
}

object Host "bar"
  var.foo = "bar"
  # Missing var.bar
  #var.bar = "foo"
}

Then add two dimentions in cube: first foo as it's set for both hosts and then for bar. 2nd dimention should crash now.

I'm not able to reproduce this.

[voiprodrigo]

This is also happening to me. Using IcingaWeb 2.5.3, and PostgreSQL

[voiprodrigo]

FYI, I reconfigured Icingaweb2 to use Mysql (MariaDB), and the problem went away.

[buzzdeee]

I don't feel alone anymore. But switching to a new DB backend, just because of this is a no-go. That would be the one and only mysql/mariadb I run. Everything runs happily on PostgreSQL.

[voiprodrigo]

@dnsmichi mentioned he could not reproduce. I wonder if it was tested only with MySQL?

[dnsmichi]

Right, this happens on PostgreSQL only. My previous tests only were with MySQL, this information came in later.

Steps to reproduce

Important: It does not work the other way around.

• Add dimension, the one which only one host has, bar
• Add a second dimension which applies to both hosts, foo

I ran today in the same issue, should be fixed with #29
