Allow to add nodes based on filter

[ValeDaRold]

This pull request represents a first iteration for solving issue #295 .

Use Case

As a Business Process user, I want to easily add new child hosts/services to an existing business process covering two different scenarios:

1. when the services check the same thing (have usually the same names) and are on multiple hosts. There can be a great number of hosts with the same check: e.g. Host1;Ping, Host2;Ping, ... Host<N>;Ping
2. when there are multiple identical services (e.g. Memory, CPU, Network) on multiple host instances of the same type e.g.

esx1;Memory, esx1;CPU, esx1;Network,
esx2;Memory, esx2;CPU, esx2;Network,
esx3;Memory, esx3;CPU, esx3;Network,

Proposed Solution

As agreed with @lippserd, we added two new node types in the AddNodeForm.php:

1. Host from filter that allows the user to filter hosts with the help of a monitoring filter
2. Service from filter that allows the user to filter services with the help of a monitoring filter
   

Once the user selects one of these two new node-type entries an input field called Filter and the Next button will appear.

The user will then insert the monitoring filter and press the button: the list of filtered host/services will populate the children multi-select. The Next button will then change into a Refresh button that allows the user to change the monitoring filter and reload the list of the monitored objects, visible in the multi-select.

• Please rebase, the change in module.info shouldn't be necessary
• The changes in the gettext catalogs have no effect here since Icinga Web 2 v2.8.0
  • Please open a PR with the same changes in https://github.com/Icinga/L10n

Hello, I used "Host from filter" option with filter hostgroup="Cloud-production" and received ALL hosts in "Hosts*" list, not only these having hostgroup = Cloud-production. (This filter works well in Overview). Can you please advise how / if this function works? Thanks, Tomas

Doesn't work anymore for me as well. Please create a new issue.

Thanks for the nice feature!
An improvement would be, implementing a synchronization job/feature, that updates all objects automatically based on set filters.

This feature would could improve the flexibility and the dynamic of the tool.

Thanks in advance, Mustafa

The feature would be nice if working. If the objects are not automatically updated based on set filters, then what are these filters for?

My state of knowledge is, that filters are currently just being used (one time) for the first init of the objects and need an interaction from the user, who would have to select all objects to be imported into the view. No usage afterwards for updating new/deleted objects (hosts/services).
