 In case a model plugin doesn't work correctly (ios, procurve, etc.), you can enable live debugging of SSH/Telnet sessions. Just add a `debug` option containing the value true to the `input` section. The log files will be created depending on the parent directory of the logfile option.

+# Creating and Extending Models
+
+Oxidized supports a growing list of [operating system types](Supported-OS-Types.md). Out of the box, most model implementations collect configuration data. Some implementations also include a conservative set of additional commands that collect basic device information (device make and model, software version, licensing information, ...) which are appended to the configuration as comments.
+
+A user may wish to extend an existing model to collect the output of additional commands. Oxidized offers smart loading of models in order to facilitate this with ease, without the need to introduce changes to the upstream source code.
+
+This methodology allows local site changes to be preserved during Oxidized version updates / gem updates.
+
+## Extending an existing model with a new command
+
+The example below can be used to extend the `JunOS` model to collect the output of `show interfaces diagnostics optics` and append the output to the configuration file as a comment. This command retrieves DOM information on pluggable optics present in a `JunOS`-powered chassis.
+
+Create the file `~/.config/oxidized/model/junos.rb` with the following contents:
+
+```ruby
+require 'oxidized/model/junos.rb'
+
+
+class JunOS
+
+
+    cmd 'show interfaces diagnostics optics' do |cfg|
+        comment cfg
+    end
+
+
+end
+```
+
+Due to smart loading, the user-supplied `~/.config/oxidized/model/junos.rb` file will take precedence over the model with the same name included in the Oxidized distribution.
+
+The code then uses `require` to initially load the Oxidized-supplied model, and extends the class defined therein with an additional command.
+
+Intuitively, it is also possible to:
+
+* Completely re-define an existing model by creating a file in `~/.config/oxidized/model/` with the same name as an existing model, but not `require`-ing the upstream model file.
+* Create a named variation of an existing model, by creating a file with a new name (such as `~/.config/oxidized/model/junos-extra.rb`), Then `require` the original model and extend its base class as in the above example. The named variation can then be specified as an OS type for specific devices that can benefit from the extra functionality. This allows for preservation of the base functionality for the default model types.
+* Create a completely new model, with a new name, for a new operating system type.
+* Testing/validation of an updated model from the [Oxidized GitHub repo models](https://github.com/ytti/oxidized/tree/master/lib/oxidized/model) by placing an updated model in the proper location without disrupting the gem-supplied model files.
+
+## Advanced features
+
+The loosely-coupled architecture of Oxidized allows for easy extensibility in more advanced use cases as well.
+
+The example below extends the functionality of the `JunOS` model further to collect `display set` formatted configuration from the device, and utilizes the multi-output functionality of the `git` output to place the returned configuration in a separate file within a git repository.
+
+It is possible to configure the `git` output to create new subdirectories under an existing repository instead of creating new repositories for each new defined output type (the default) by including the following configuration in the `~/.config/oxidized/config` file:
+
+```yaml
+output:
+    git:
+        type_as_directory: true
+```
+
+Then, `~/.config/oxidized/model/junos.rb` is adapted as following:
+
+```ruby
+require 'oxidized/model/junos.rb'
+
+
+class JunOS
+
+
+    cmd 'show interface diagnostic optics' do |cfg|
+        comment cfg
+    end
+
+    cmd 'show configuration | display set' do |cfg|
+        cfg.type = "junos-set"
+        cfg.name = "set"
+        cfg
+    end
+
+
+end
+```
+
+The output of the `show configuration | display set` command is marked with a new arbitrary alternative output type, `junos-set`.  The `git` output will use the output type to create a new subdirectory by the same name. In this subdirectory, the `git` output will create files with the name `<devicename>--set` that will contain the output of this command for each device.

+=====================

+
+The main differences are:
+- the prompt for username is different (looks quite strange for older models)
+- enable password
+  - the older model prompts for enable password and it expects empty string
+  - the newer model does not prompt for enable password at all
+

+## Custom SQL Query Support
+
+You may also implement a custom SQL query to retrieve the nodelist using  SQL syntax with the `query:` configuration parameter under the `sql:` stanza.
+
+### Custom SQL Query Examples
+
+You may have a table named `nodes` which contains a boolean to indicate if the nodes should be enabled (fetched via oxidized). This can be used in the custom SQL query to avoid fetching from known impacted nodes.
+
+In your configuration, you would add the `query:` parameter and specify the SQL query. Make sure to put this within the `sql:` configuration section.
+
+```sql
+query: "SELECT * FROM nodes WHERE enabled = True"
+```
+
+Since this is an SQL query, you can also provide a more advanced query to assist in more complicated oxidized deployments. The exact deployment is up to you on how you design your database and oxidized fetchers.
+
+In this example we limit the nodes to two "POPs" of `mypop1` and `mypop2`. We also require the nodes to have the `enabled` boolean set to `True`.
+
+```sql
+query: "SELECT * FROM nodes WHERE pop IN ('mypop1','mypop2') AND enabled = True"
+```
+
+The order of the nodes returned will influence the order that nodes are fetched by oxidized. You can use standard SQL `ORDER BY` clauses to influence the node order.
+
+You should always test your SQL query before using it in the oxidized configuration as there is no syntax or error checking performed before sending it to the database engine.
+
+Consult your database documentation for more information on query language and table optimization.
