Integrate ALB with Prometheus monitoring

Managed Service for Prometheus monitors your Application Load Balancer (ALB) instances and provides metrics, dashboards, and alerts. This topic explains how to set up the integration and use Managed Service for Prometheus.

Overview

Alibaba Cloud Prometheus Service integrates with the open source Prometheus ecosystem. It monitors various components, includes a variety of out-of-the-box monitoring dashboards, and provides a hosted Prometheus service. For more information, see What is Prometheus Service?.

ALB integrates with Managed Service for Prometheus through Enterprise CloudMonitor Integration (Paid). For more information, see the table below.

Description

Storage fee

Enterprise Cloud Monitor integration (paid)

Prometheus monitoring retrieves metrics through the Cloud Monitor API. After you integrate ALB with Prometheus monitoring, you can monitor the ALB service and configure alarms using the cloud service dashboard and alarm rules.

Cloud Monitor charges traffic fees for reporting ALB metrics.

Prometheus monitoring stores the reported metrics free of charge.

Billing example

The billing example in the following figure is for reference only. For actual fees, see the purchase page.

An ALB instance has 2 listeners and 3 forwarding rules. There are 27 metrics for the instance and for each listener, 16 for each forwarding rule, and 11 for each server group.

Total metrics per minute = 27 × 1 ALB instance + 27 × 2 listeners + 16 × 3 forwarding rules + 11 × 2 server groups = 151

Total data points per day for CloudMonitor pay-as-you-go = 151 × 60 × 24 = 217,440

Prerequisites

You have activated Application Real-Time Monitoring Service (ARMS). For details, see Activate ARMS.
You have activated Managed Service for Prometheus Pro Edition. For details, see Activate Managed Service for Prometheus Pro Edition.

Create a Prometheus instance

Important

Monitoring data is available only at minute-level granularity. Displayed second-level metrics are one-minute averages and may not accurately reflect sudden changes within that minute. For second-level monitoring, enable the access log feature. For more information, see ALB access log.

Log on to the Cloud Monitor console.
In the top navigation bar, select a region, and then click Create Prometheus Instance.

On the Create Instance page, configure the following parameters and then click Create.

Parameter	Description
Instance type	Select general-purpose instance or global aggregation instance. Note general-purpose instance: A standard Prometheus instance suitable for various scenarios. It serves as remote write storage (Remote Write) for self-managed Prometheus services or ingests metrics from containers, cloud services, and hosts. global aggregation instance: A virtual instance that aggregates data from multiple Alibaba Cloud Prometheus instances or self-managed Prometheus clusters. It provides unified metric queries, a single Grafana data source, and centralized alerting across all aggregated sources.
Retention period	Select a retention period of 90 days or 180 days.

ALB and Prometheus integration

Log in to the ARMS console.
In the left-side navigation pane, click Integration Center.
On the Integration Center page, click the Middleware tab, and then click Alibaba Cloud ALB.
In the Alibaba Cloud ALB panel, select the region to store your data and click OK. It takes about 1 to 2 minutes to integrate the ALB monitoring data.

Metrics

You can view ALB monitoring metrics on the Metrics tab.

Metric count: The number of metrics written to the database within the last 10 minutes.

Dashboard

On the Get Started tab, go to Access Management > Component Management > Dashboard and click ALB to view its performance metrics.
Alerts

You can create Prometheus alerting rules on the Alerting rule template tab and view monitoring alerts. For instructions on how to create an alerting rule, see Create a Prometheus alerting rule.

Third-party Prometheus instance

After integrating Application Load Balancer (ALB) with Managed Service for Prometheus, you can use remote write to integrate a self-managed Prometheus instance. For more information, see Prometheus instance for General-purpose.

Disable ALB monitoring

Log on to the Cloud Monitor console.
On the Instances page, select the target region in the top navigation bar, find the target instance, and click Uninstall in the Actions column.
In the confirmation dialog box, click OK.
