Volcengine Managed Service for Prometheus

Middleware integration

etcd integration

Volcengine Managed Service for Prometheus (VMP) allows you to monitor ETCD instances that are deployed in Volcengine Kubernetes Engine (VKE) clusters.

Background

ETCD is an open source, distributed, consistent key-value store used for shared configuration, service discovery, and scheduler coordination of distributed systems or machine clusters. ETCD helps facilitate more secure automatic updates, coordinates work being scheduled to hosts, and assists in setting up the container overlay networking.

You can use VMP to monitor core metrics such as the status of ETCD nodes deployed in VKE clusters, data consistency, request latency, and storage performance in real time. This ensures the stability of distributed system configuration management and service discovery.

Prerequisites

A VMP workspace has been created. For details, see Creating workspaces.

VKE has been activated.

A cluster has been created. For details, see Creating clusters.

An ETCD instance is deployed in the cluster.

Cloud native observability has been enabled for the cluster, and prometheus-agent has been installed in the cluster. For details, see Enabling observability.

tip

The VMP workspace and the VKE cluster must be deployed in the same region.

Procedure

Configure an integration task

In the top navigation bar, select the target region.

In the left navigation bar, click Integration Center > Component. On the page that appears, find and click ETCD to configure the integration task.

Configure the deployment environment of the collector. Click VKE environment and select an associated cluster.

Click Create Integration Task to specify the details of the integration task.

Parameter	Description
Basic information
Task name	Specify the name of the integration task. It can contain Chinese characters, letters (uppercase and lowercase), digits, and underscores (_), and must be 1 to 40 characters in length.
Scrape configuration
JobLabel	You can select labels from Kubernetes Pod objects, and the label value will be used as the job label for all metrics. For example, if you set the JobLabel parameter to foo and the Pod label is foo: bar, the system will add a job="bar" label to all collected metrics. If this parameter is left empty, the default job label for the metrics consists of the namespace and name of the PodMonitor object, which is in the format <namespace>/<name>.
Metric scraping interval	Configure the collection interval of the collector.
Namespace	Configure the namespace where the collection target is deployed in the cluster. Values: arbitrary: indicates that metrics of resources in any namespace in the cluster can be collected. custom: indicates that you can specify custom namespaces in the cluster, and only metrics of resources in the specified namespaces can be collected. For example, if you set the value to default, only metrics of resources in the default namespace can be collected.
Metric acquisition port	Configure the metric port for the collection target. You can set the value to a port name or a port number.
Metric acquisition path	Configure the metric path of the collection target.
LabelSelector	Select collection targets by using the labels of Kubernetes Pod objects.
Advanced configuration
Metric Relabel configuration	Configure metric relabeling. For more details, refer to Metric relabeling.

Click Confirm to complete the configuration.

Obtain monitoring dashboards

Click the Effect preview tab to view sample monitoring dashboards. Click Get the Grafana template to download the Grafana monitoring dashboard template in JSON format.

Query metrics

Click the Acquisition metric tab to view the list of metrics for the collection targets.

View preset alerts

Click the Alert template tab to view the preset alert templates for ETCD. Click Turn on alert. You are redirected to the alert group creation page, where you can swiftly create and enable alerts based on the current alert template.

Validate results

After the configuration is complete, you can view the status and details of the integration task to check whether the task is running as expected.

In the left navigation bar, click Integration Center > Integration task.

Click VKE environment. You can view the status of the integration task in the task list.

After the integration task is created, you can perform the following O&M operations:

Click the name of the task to go to the task details page.

Click Edit in the Actions column to edit the task.

Click Suspend task in the Actions column to suspend the task.

Click Delete in the Actions column to delete the integration task.

Monitoring information

Query metrics

You can quickly query and display metric data by using the Explore feature of VMP. For more details, refer to Querying metrics.

Create dashboards

You can install Grafana in a VKE cluster or an ECS instance and then use Grafana to view metrics and create dashboards.

Deploying Grafana in a VKE cluster and accessing workspaces

Deploying Grafana on an ECS instance and integrating Grafana with a workspace

Configure alerts

You can configure alerts for Nacos instances in the Alert Center of VMP. For details, see Creating alert rules.
