====Modular Output System====

The **Modular Output System** is designed to help you get your output information to where you need it.

The system is primarily designed around transmitting [[key-value|key-value]] information (ie. a point with both a //name// and a //value//) and [[event log|event logs]] to the destination(s) of your choice.

The modular output system is found in [[model:start|ModelHost]], [[agency:Welcome|Agency]], [[trigger:Trigger]] and ARDIs internal alert management system, but can also be used in other projects.

===Configuring===

Each app that supports the Modular Output System includes an //output configuration file// (usually called 'output.json', which is a JSON-encoded file that provides instructions on where output data should be sent.

The file looks like the example below...

<code>
[
   { 
      "type": "value_or_event",
      "method": "methodname",
      "paramername": "parametervalue" 
   }
]
</code>

===Methods===

Each object indicates a single **method** of processing your output.

A method normally indicates a particular protocol, such as sending data to MySQL or the Prometheus time-series database.

Some of these methods will need additional parameters - for instance, you'll need the database name, table name, host and user credentials if you're sending data to a relational database like Microsoft SQL Server.

===Method List===

Below you'll find the pre-made output methods that are included with ARDI.

The examples given show the options available for the specific //method//. There are also some [[common options|common options]] for output modules that can be set.
