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

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">
<arguments>
<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>
</argument>
</arguments>
</type>
