| <title>CloudMonkey</title> |
| <para>CloudMonkey is the &PRODUCT; Command Line Interface (CLI). It is written in Python. CloudMonkey can be used both as an interactive shell and as a command line tool which simplifies &PRODUCT; configuration and management. It can be used with &PRODUCT; releases since the 4.0.x branch.</para> |
| <warning> |
| <para>CloudMonkey is still under development and should be considered a Work In Progress (WIP), the wiki is the most up to date documentation:</para> |

| <para>There are three ways to get CloudMonkey. Via the official &PRODUCT; source releases or via a community maintained distribution at <ulink url="http://pypi.python.org/pypi/cloudmonkey/">the cheese shop</ulink>.

| <para>To configure CloudMonkey you can edit the ~/.cloudmonkey/config file in the user's home directory as shown below. The values can also be set interactively at the cloudmonkey prompt. Logs are kept in ~/.cloudmonkey/log, and history is stored in ~/.cloudmonkey/history. Discovered apis are listed in ~/.cloudmonkey/cache. Only the log and history files can be custom paths and can be configured by setting appropriate file paths in ~/.cloudmonkey/config</para> |

| <section id="cliapidiscovery"> |
| <title>API Discovery</title> |
| <note> |
| <para>In &PRODUCT; 4.0.* releases, the list of api calls available will be pre-cached, while starting with &PRODUCT; 4.1 releases and above an API discovery service is enabled. CloudMonkey will discover automatically the api calls available on the management server. The sync command in CloudMonkey pulls a list of apis which are accessible to your user role, along with help docs etc. and stores them in ~/.cloudmonkey/cache. This allows cloudmonkey to be adaptable to changes in mgmt server, so in case the sysadmin enables a plugin such as Nicira NVP for that user role, the users can get those changes. New verbs and grammar (DSL) rules are created on the fly.</para> |
| </note> |
| <para>To discover the APIs available do:</para> |
| <programlisting> |
| > sync |
| 324 APIs discovered and cached |
| </programlisting> |
| </section> |
| |
| <section id="clitabularoutput"> |
| <title>Tabular Output</title> |
| <para>The number of key/value pairs returned by the api calls can be large resulting in a very long output. To enable easier viewing of the output, a tabular formatting can be setup. You may enable tabular listing and even choose set of column fields, this allows you to create your own field using the filter param which takes in comma separated argument. If argument has a space, put them under double quotes. The create table will have the same sequence of field filters provided</para> |
| <para>To enable it, use the <emphasis>set</emphasis> function and create filters like so:</para> |
| <programlisting> |
| > set tabularize true |
| > list users filter=id,domain,account |
| count = 1 |
| user: |
| +--------------------------------------+--------+---------+ |
| | id | domain | account | |

| <title>Interactive Shell Usage</title> |
| <para>To start learning CloudMonkey, the best is to use the interactive shell. Simply type CloudMonkey at the prompt and you should get the interactive shell.</para> |
| <para>At the CloudMonkey prompt press the tab key twice, you will see all potential verbs available. Pick on, enter a space and then press tab twice. You will see all actions available for that verb</para> |
