# Marathon Integration

## Overview

The Agent's Marathon check lets you:

- Track the state and health of every application: see configured memory, disk, cpu, and instances; monitor the number of healthy and unhealthy tasks
- Monitor the number of queued applications and the number of deployments

## Setup

### Installation

The Marathon check is included in the [Datadog Agent][1] package. No additional installation is needed on your server.

### Configuration

Follow the instructions below to configure this check for an Agent running on a host. For containerized environments, see the [Containerized](#containerized) section.

<!-- xxx tabs xxx -->
<!-- xxx tab "Host" xxx -->

#### Host

To configure this check for an Agent running on a host:

##### Metrics collection

1. Edit the `marathon.d/conf.yaml` file, in the `conf.d/` folder at the root of your [Agent's configuration directory][2]. See the [sample marathon.d/conf.yaml][3] for all available configuration options:

   ```yaml
   init_config:

   instances:
     # the API endpoint of your Marathon master; required
     - url: "https://<SERVER>:<PORT>"
       # if your Marathon master requires ACS auth
       #   acs_url: https://<SERVER>:<PORT>

       # the username for Marathon API or ACS token authentication
       username: "<USERNAME>"

       # the password for Marathon API or ACS token authentication
       password: "<PASSWORD>"
   ```

   The function of `username` and `password` depends on whether or not you configure `acs_url`. If you do, the Agent uses them to request an authentication token from ACS, which it then uses to authenticate to the Marathon API. Otherwise, the Agent uses `username` and `password` to directly authenticate to the Marathon API.

2. [Restart the Agent][4].

##### Log collection

_Available for Agent versions >6.0_

1. Collecting logs is disabled by default in the Datadog Agent, enable it in your `datadog.yaml` file:

   ```yaml
   logs_enabled: true
   ```

2. Because Marathon uses logback, you can specify a custom log format. With Datadog, two formats are supported out of the box: the default one provided by Marathon and the Datadog recommended format. Add a file appender to your configuration as in the following example and replace `$PATTERN$` with your selected format:

   - Marathon default: `[%date] %-5level %message \(%logger:%thread\)%n`
   - Datadog recommended: `%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n`

   ```xml
     <?xml version="1.0" encoding="UTF-8"?>

     <configuration>
         <shutdownHook class="ch.qos.logback.core.hook.DelayingShutdownHook"/>
         <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
             <encoder>
                 <pattern>[%date] %-5level %message \(%logger:%thread\)%n</pattern>
             </encoder>
         </appender>
         <appender name="async" class="ch.qos.logback.classic.AsyncAppender">
             <appender-ref ref="stdout" />
             <queueSize>1024</queueSize>
         </appender>
         <appender name="FILE" class="ch.qos.logback.core.FileAppender">
             <file>/var/log/marathon.log</file>
             <append>true</append>
             <!-- set immediateFlush to false for much higher logging throughput -->
             <immediateFlush>true</immediateFlush>
             <encoder>
                 <pattern>$PATTERN$</pattern>
             </encoder>
         </appender>
         <root level="INFO">
             <appender-ref ref="async"/>
             <appender-ref ref="FILE"/>
         </root>
     </configuration>
   ```

3. Add this configuration block to your `marathon.d/conf.yaml` file to start collecting your Marathon logs:

   ```yaml
   logs:
     - type: file
       path: /var/log/marathon.log
       source: marathon
       service: "<SERVICE_NAME>"
   ```

4. [Restart the Agent][4].

<!-- xxx tab "Containerized" xxx -->

#### Containerized

For containerized environments, see the [Autodiscovery Integration Templates][5] for guidance on applying the parameters below.

##### Metric collection

| Parameter            | Value                                  |
| -------------------- | -------------------------------------- |
| `<INTEGRATION_NAME>` | `marathon`                             |
| `<INIT_CONFIG>`      | blank or `{}`                          |
| `<INSTANCE_CONFIG>`  | `{"url": "https://%%host%%:%%port%%"}` |

##### Log collection

_Available for Agent versions >6.0_

Collecting logs is disabled by default in the Datadog Agent. To enable it, see [Kubernetes Log Collection][6].

| Parameter      | Value                                                 |
| -------------- | ----------------------------------------------------- |
| `<LOG_CONFIG>` | `{"source": "marathon", "service": "<SERVICE_NAME>"}` |

<!-- xxz tab xxx -->
<!-- xxz tabs xxx -->

### Validation

[Run the Agent's status subcommand][7] and look for `marathon` under the Checks section.
