# Spark History Server provider

The **Spark History Server provider** collects metrics from a Spark History Server instance and makes them available to Akamas.

Prerequisites

This section provides the minimum requirements that you should match before using the Spark History Server telemetry provider.

### Supported versions <a href="#supported-versions" id="supported-versions"></a>

* Apache Spark 2.3

### Network requirements <a href="#network-requirements" id="network-requirements"></a>

* Spark History Server API must be reachable at the provided address and port (the default port is `18080`).

## Supported component types <a href="#supported-component-types" id="supported-component-types"></a>

* spark-application

You can check [Spark History Server provider metrics mapping](https://docs.akamas.io/akamas-docs/3.6/reference/optimization-packs/spark-pack) to see how component-types metrics are extracted by this provider.

## Akamas supported version <a href="#akamas-supported-version" id="akamas-supported-version"></a>

* Versions < 2.0.0 are compatible with Akamas until version 1.8.0
* Versions >= 2.0.0 are compatible with Akamas from version 1.9.0

## Workflow requirements <a href="#workflow-requirements" id="workflow-requirements"></a>

This section lists the workflow operators this provider depends on:

* [SparkSubmit Operator](https://docs.akamas.io/akamas-docs/3.6/reference/workflow-operators/sparksubmit-operator)
* [SparkSSHSubmit operator](https://docs.akamas.io/akamas-docs/3.6/reference/workflow-operators/sparksshsubmit-operator)
* [SparkLivy Operator](https://docs.akamas.io/akamas-docs/3.6/reference/workflow-operators/sparklivy-operator)

## Components configuration

Akamas uses components to identify specific elements of the system to be monitored and optimized. Your system might contain multiple components to model, for example, a Spark application and each host of the cluster. To point Akamas to the right component when extracting metrics you need to add a property called `sparkApplication` to your Spark Application component. The provider will only extract metrics for components for which this property has been specified.

```yaml
name: My Application
properties:
 sparkApplication: "true"
```
