Managed Service for Prometheus:Use Managed Service for Prometheus to monitor Tencent Cloud resources

Procedure

The following figure describes how to use Managed Service for Prometheus to monitor a Tencent Cloud resource:

Step 1: Deploy the QCloud exporter

1. Build an image.

   git clone https://github.com/tencentyun/tencentcloud-exporter.git
   make build

2. Configure the resource and the instances.

   • Configure the credentials of TencentCloud API.

   • Configure the resource and the instances whose metrics you want to export.

   If you want to export all metrics of all CVM instances, you can use the following code:

   credential:
     access_key: "access_key"  #The SecretId of TencentCloud API.
     secret_key: "secret_key"  #The SecretKey of TencentCloud API.
     region: "ap-nanjing" #The region where the instances reside.
   
   rate_limit: 15              #The maximum number of API calls that CM can make per second to pull data. Example: 20. For more information, see https://cloud.tencent.com/document/product/248/31014.
   
   products:
     - namespace: QCE/CVM      #For more information about the metrics, see https://cloud.tencent.com/document/product/248/6843.
       all_metrics: true       #Specifies that all supported metrics are exported.
       all_instances: true     #Specifies that the metrics of all instances in the specified region are exported.
       #only_include_metrics: []
       #only_include_instances: [ins-xxxxxxxx]
       extra_labels: [InstanceId, InstanceName] #The metric labels to which the fields of instances are exported.
       #statistics_types: [last]
       #period_seconds: 60
       #metric_name_type: 2

   Note

   For more information about how to configure the QCloud.yaml file, see tencentcloud-exporter.

3. Deploy the QCloud exporter.

   Create a Docker image by using the preceding YAML file and upload the image to an image repository, such as DockerHub or Alibaba Cloud Container Registry.

   1. Log on to the ACK console. In the left-side navigation pane, click Clusters.

   2. On the Clusters page, find the cluster that you want to manage and click Applications in the Actions column.

   3. Create a container group.

      1. In the left-side navigation pane, choose Workloads > Deployments.

      2. On the Deployments page, click Create from YAML.

      3. On the Create page, enter the following code in the Template code editor and click Create:

         apiVersion: apps/v1
         kind: Deployment
         metadata:
           generation: 5
           labels:
             app: qcloud-exporter-demo
           name: qcloud-exporter-demo
           namespace: default
         spec:
           replicas: 1
           selector:
             matchLabels:
               app: qcloud-exporter-demo
           template:
             metadata:
               labels:
                 app: qcloud-exporter-demo
             spec:
               containers:
                 - args:
                     - '--config.file=/usr/local/etc/qcloud-cvm-product.yml'
                   image: 'registry.cn-hangzhou.aliyuncs.com/fuling/qcloud-exporter:v0.1'
                   imagePullPolicy: Always
                   name: qcloud-exporter
                   ports:
                     - containerPort: 9123
                       name: web-normal
                       protocol: TCP

   4. Create a service.

      1. In the left-side navigation pane, choose Network > Services.

      2. On the Services page, click Create Resources in YAML.

      3. On the Create page, enter the following code in the Template code editor and click Create:

         apiVersion: v1
         kind: Service
         metadata:
           labels:
             app: qcloud-exporter-demo
           name: qcloud-exporter-demo-svc
           namespace: default
         spec:
           ports:
             - name: qcloud-exporter-metrics
               port: 9123
               protocol: TCP
               targetPort: 9123
           selector:
             app: qcloud-exporter-demo

Step 2: Add a service discovery configuration

1. Log on to the Managed Service for Prometheus console.

2. In the left-side navigation pane, click Instances.

3. In the top navigation bar, select the region where the ACK cluster resides, and click the name of the cluster.

4. In the left-side navigation pane, click Service Discovery. Then, click the Configure tab.

5. On the Configure tab, click the ServiceMonitor tab and click Add ServiceMonitor. In the Add ServiceMonitor dialog box, enter the following code and click OK.

   apiVersion: monitoring.coreos.com/v1
   kind: ServiceMonitor
   metadata:
     name: qcloud-exporter-sm
     namespace: default
   spec:
     endpoints:
     - interval: 60s
       path: /metrics
       port: qcloud-exporter-metrics
       scrapeTimeout: 60s
     namespaceSelector:
       any: true
     selector:
       matchLabels:
         app: qcloud-exporter-demo

   The service discovery configuration is displayed on the ServiceMonitor tab.

   

Step 3: Create an alert rule

Create an alert rule. For more information, see Create an alert rule for a Prometheus instance.
