Import and Synchronization
|
|
==========================
|
|
|
|
Icinga Director offers very powerful mechanisms when it comes to fetching data
|
|
from external data sources.
|
|
|
|
The following examples should give you a quick idea of what you might want to
|
|
use this feature for. Please note that Import Data Sources are implemented as
|
|
hooks in Director. This means that it is absolutely possible and probably very
|
|
easy to create custom data sources for whatever kind of data you have. And you
|
|
do not need to modify the Director source code for this, you can ship your very
|
|
own importer in your very own Icinga Web 2 module.
|
|
|
|
Examples
|
|
--------
|
|
|
|
### Import Servers from MS Active Directory
|
|
|
|
#### Create a new import source
|
|
|
|
Importing data from LDAP sources is pretty easy. We use MS Active Directory
|
|
as an example source:
|
|
|
|

|
|
|
|
You must formerly have configured a corresponding LDAP resource in your Icinga Web.
|
|
Then you choose your preferred object class, you might add custom filters, a search
|
|
base should always be set.
|
|
|
|
The only tricky part here are the chosen Properties. You must know them and you
|
|
are required to fill them in, no way around this right now. Also please choose one
|
|
column as your key column.
|
|
|
|
In case you want to avoid trouble please make this the column that corresponds to
|
|
your desired object name for the objects you are going to import. Rows duplicating
|
|
this property will be considered erroneous, the Import would fail.
|
|
|
|
#### Property modifiers
|
|
|
|
Data sources like SQL databases provide very powerful modifiers themselves. With a
|
|
handcrafted query you can solve lots of data conversion problems. Sometimes this is
|
|
not possible, and some sources (like LDAP) do not even have such features.
|
|
|
|
This is where property modifiers jump in to the rescue. Your computer names are
|
|
uppercase and you hate this? Use the lowercase modifier:
|
|
|
|

|
|
|
|
You want to have the object SID as a custom variable, but the data is stored
|
|
binary in your AD? There is a dedicated modifier:
|
|
|
|

|
|
|
|
You do not agree with the way Microsoft represents it's version numbers? Regular
|
|
expressions are able to fix everything:
|
|
|
|

|
|
|
|
#### Preview
|
|
|
|
A quick look at the preview confirms that we reached a good point, that's the data
|
|
we want:
|
|
|
|

|
|
|
|
#### Synchronization
|
|
|
|
The Import itself just fetches raw data, it does not yet try to modify any of your
|
|
Icinga objects. That's what the Sync rules have been designed for. This distinction
|
|
has a lot of advantages when it goes to automatic scheduling for various import and
|
|
sync jobs.
|
|
|
|
When creating a Synchronization rule, you must decide which Icinga objects you want
|
|
to work with. You could decide to use the same import source in various rules with
|
|
different filters and properties.
|
|
|
|

|
|
|
|
For every property you must decide whether and how it should be synchronized. You
|
|
can also define custom expressions, combine multiple source fields, set custom
|
|
properties based on custom conditions and so on.
|
|
|
|

|
|
|
|
Now you are all done and ready to a) launch the Import and b) trigger your synchronization
|
|
run.
