# Create Dynatrace telemetry instances

The installed provider is shared with all users of your Akamas installation and can monitor many different systems, by configuring appropriate telemetry provider instances.

To create an instance of the Dynatrace provider, build a YAML file (`instance.yml` in this example) with the definition of the instance:

```yaml
# Dynatrace Telemetry Provider Instance
provider: Dynatrace
config:
  url: https://wuy711522.live.dynatrace.com
  token: XbERgThisIsAnExampleToken
```

Then you can create the instance for the `system` using the Akamas CLI:

```bash
akamas create telemetry-instance instance.yml system
```

### Configuration options <a href="#configuration-options" id="configuration-options"></a>

When you create an instance of the Dynatrace provider, you should specify some configuration information to allow the provider to correctly extract and process metrics from Dynatrace.

You can specify configuration information within the `config` part of the YAML of the instance definition.

#### Required properties <a href="#required-properties" id="required-properties"></a>

* `url` - URL of the Dynatrace installation API (see <https://www.dynatrace.com/support/help/extend-dynatrace/dynatrace-api/> to retrieve the URL of your installation)
* `token` - A Dynatrace API Token with the [proper permissions](https://docs.akamas.io/akamas-docs/3.6/integrating/integrating-telemetry-providers/dynatrace-provider/..#permissions)

#### Collect additional metrics <a href="#collect-additional-metrics" id="collect-additional-metrics"></a>

You can collect additional metrics with the Dynatrace provider by using the `metrics` field:

```yaml
config:
  url: https://wuy71982.live.dynatrace.com
  token: XbERgkKeLgVfDI2SDwI0h
metrics:
- metric: "akamas_metric"                     # extra akamas metrics to monitor
  datasourceMetric: builtin:host:new_metric   # query to execute to extract the metric
  labels:
  - "method"      # the "method" label will be retained within akamas
```

#### Configure a proxy for Dynatrace <a href="#configure-a-proxy-for-dynatrace" id="configure-a-proxy-for-dynatrace"></a>

In the case in which Akamas cannot reach directly your Dynatrace installation, you can configure an HTTP proxy by using the `proxy` field:

```yaml
config:
  url: https://wuy71982.live.dynatrace.com
  token: XbERgkKeLgVfDI2SDwI0h
  proxy:
    address: https://dynaproxy  # the URL of the HTTP proxy
    port: 9999                  # the port the proxy listens to
```

### Telemetry instance reference <a href="#telemetry-instance-reference" id="telemetry-instance-reference"></a>

This section reports the complete reference for the definition of a telemetry instance.

```yaml
provider: Dynatrace  # this is an instance of the <name> provider
config:
  url: https://wuy71982.live.dynatrace.com
  token: XbERgkKeLgVfDI2SDwI0h
  proxy:
    address: https://dynaproxy # the URL of the HTTP proxy
    port: 9999            # the port the proxy listens to
    username: myusername  # http basic auth username if necessary
    password: mypassword  # http basic auth password if necessary
  tags:
    Environment: Test       # dynatrace tags to be matched for every component

metrics:
- metric: "cpu_usage"  # this is the name of the metric within Akamas
  # The Dynatrace metric name
  datasourceMetric: "builtin:host.cpu.usage"
  extras:
    mergeEntities: true  # instruct the telemetry to aggregate the metric over multiple entities
  aggregation: avg  # The aggregation to perform if the mergeEntities property is set to true
```

This table shows the reference for the `config` section within the definition of the Dynatrace provider instance:

## Use cases <a href="#use-cases" id="use-cases"></a>

This section reports common use cases addressed by this provider.

### Collect system metrics <a href="#collect-system-metrics" id="collect-system-metrics"></a>

Check the Linux optimization pack for a list of all the system metrics available in Akamas.

As a first step to start extracting metrics from Dyntrace, [generate your API token](https://www.dynatrace.com/support/help/extend-dynatrace/dynatrace-api/basics/dynatrace-api-authentication/) and make sure it has the right permissions.

As a second step, choose a strategy to map your Linux component (*MyLinuxComponent*) with the corresponding Dyntrace entity.

Let’s assume you want to **map by id** your Dynatrace entity, you can find the id in the URL bar of a Dyntrace dashboard of the entity:

<figure><img src="https://4103111959-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzrIhBBVa4sw46ol13SWX%2Fuploads%2Fgit-blob-d2f85e5277af378c5cf1bbeb04b6d61a4db15d6f%2Fdyna-dash-url.png?alt=media" alt=""><figcaption></figcaption></figure>

Grab the id and add it to the Linux component definition:

```yaml
name: MyLinuxComponent
description: this is a Linux component
properties:
  dynatrace:
    id: HOST-A987D45512ABCEEE
```

You can leverage the name of the entity as well:

```yaml
name: MyLinuxComponent
description: this is a Linux component
properties:
  dynatrace:
    name: Host1
```

As a third and final step, once the component is all set, you can create an instance of the Dynatrace provider and then build your first studies:

```yaml
name: Dynatrace
config:
  url: https://my_dyna_installation_url
  token: MY_DYNA_TOKEN
```
