This Magento 2 Module exposes a new route under /metrics with Magento 2 specific metrics in the format of
[prometheus](https://prometheus.io). The different metrics are grouped into modules and can be enabled/disabled via the
Magento Backend.

## Installation

Install the Module via composer by running:

```
composer require run-as-root/magento2-prometheus-exporter
php bin/magento setup:upgrade
```

## Module Configuration

The modules system configuration is located under `Stores -> Configuration -> Prometheus -> Metric Configuration`. You
can enable or disable specific metrics by using the multiselect.

## Prometheus Configuration

After installing the Magento Module, your Prometheus needs to get pointed to your Magento Metrics endpoint. To do so,
add the following lines to your prometheus.yml under scrape_configs:

``` yaml
- job_name: 'Magento 2 Exporter'
scrape_interval: 5m
scrape_timeout: 60s
metrics_path: /metrics
# The bearer token can be generated in the Magento Admin. Using the auth is optional.
# bearer_token: YOUR_BEARER_TOKEN
static_configs:
- targets:
- your-magento-url
```

## Module functionality

The module registers a cron job that runs every minute. The cronjob is responsible for aggregating the metric data. The
aggregated data is stored in the table `run_as_root_prometheus_metrics`. The added controller collects the data stored
in the table and renders the correct response for prometheus.

## Metrics

The following metrics will be collected:

| Metric | Labels | TYPE | Help |
|:-------------------------------------|:--------------------------------|:--------|:--------------------------------------------------------------------------------|
| magento_orders_count_total | status, store_code | gauge | All Magento Orders |
| magento_orders_amount_total | status, store_code | gauge | Total amount of all Magento Orders |
| magento_order_items_count_total | status, store_code | gauge | Total count of orderitems |
| magento_cms_block_count_total | store_code | gauge | Total count of available cms blocks |
| magento_cms_page_count_total | store_code | gauge | Total count of available cms pages |
| magento_customer_count_total | store_code | gauge | Total count of available customer |
| magento_cronjob_broken_count_total | | gauge | Broken CronJobs occur when when status is pending but execution_time is set. |
| magento_cronjob_count_total | status, job_code | gauge | Total count of available CronJob Count. |
| magento_indexer_backlog_count_total | title | gauge | Total count of backlog item in indexer (the data from `indexer:status` command) |
| magento_shipments_count_total | source, store_code | counter | Count of Shipments created by store and source. |
| magento_catalog_category_count_total | status, menu_status, store_code | gauge | Count of Categories by store, status and menu status. |
| magento_store_count_total | status | gauge | Total count of Stores by status. |
| magento_website_count_total | | gauge | Total count websites. |
| magento_products_by_type_count_total | project_type | gauge | Total count of products by type. |

## Add you own Metric

To add a new metric, you need to implement the `\RunAsRoot\PrometheusExporter\Api\MetricAggregatorInterface`. The metric
aggregator object is responsible for collecting the necessary information for the specific metric from magento and then
add a new metric record. New records can be easily added via
`\RunAsRoot\PrometheusExporter\Service\UpdateMetricService`.

In addition to the implementation of the MetricAggregatorInterface, you have to add your specific Aggregator to the
`MetricAggregatorPool` defined in the `di.xml`. For example:

``` xml



RunAsRoot\PrometheusExporter\Aggregator\Order\OrderAmountAggregator
RunAsRoot\PrometheusExporter\Aggregator\Order\OrderCountAggregator
RunAsRoot\PrometheusExporter\Aggregator\Order\OrderItemAmountAggregator
RunAsRoot\PrometheusExporter\Aggregator\Order\OrderItemCountAggregator



```
