Magento2 Prometheus Exporter





Requires (dev)










Magento 2 Prometheus Exporter

Branch stable codecov pipeline status

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


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:

- job_name: 'Magento 2 Exporter'
  scrape_interval: 5m
  scrape_timeout: 60s
  metrics_path: /metrics
  - 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.


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

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:

<type name="RunAsRoot\PrometheusExporter\Metric\MetricAggregatorPool">
            <argument name="items" xsi:type="array">
                <item name="OrderAmountAggregator" xsi:type="object">RunAsRoot\PrometheusExporter\Aggregator\Order\OrderAmountAggregator</item>
                <item name="OrderCountAggregator" xsi:type="object">RunAsRoot\PrometheusExporter\Aggregator\Order\OrderCountAggregator</item>
                <item name="OrderItemAmountAggregator" xsi:type="object">RunAsRoot\PrometheusExporter\Aggregator\Order\OrderItemAmountAggregator</item>
                <item name="OrderItemCountAggregator" xsi:type="object">RunAsRoot\PrometheusExporter\Aggregator\Order\OrderItemCountAggregator</item>
