Procedure to enable Alibaba Prometheus (ARMS) in Container Cluster Management.
Prometheus, an open-source monitoring toolkit, has been deeply integrated with Alibaba Cloud Kubernetes Service (ACK). This guide will walk you through setting up ARMS (Alibaba Cloud Realtime Monitoring Service) Prometheus in your ACK cluster using different methods.

Pre-requisites

  • Kubectl Installation
    : Ensure you have
    kubectl
     installed on your client. If not, download and install kubectl, and perform the required installation procedure.

Procedure

You can use one of the following methods to enable ARMS Prometheus:

Enable ARMS Prometheus by setting cluster parameters

To enable ARMS Prometheus for monitoring within the Alibaba Cloud Kubernetes Service (ACK), follow these user-centered steps:
  1. Begin by logging into the ACK console.
  2. Navigate to the left-side pane and select
    Clusters
    .
  3. In the Clusters page, find the option to
    Create Kubernetes Cluster
     in the upper-right corner and select it.
  4. Choose the desired cluster template. As you set up the cluster parameters, locate the
    Component Configurations
     wizard page. Here, ensure you select
    Enable Prometheus Monitoring
    .
    By default, Enable Prometheus Monitoring is selected when you create a cluster. After the cluster is created, the system automatically configures ARMS Prometheus.

Enable ARMS Prometheus on the App Catalog page in the ACK console

To streamline the monitoring process using ARMS Prometheus within the Alibaba Cloud Kubernetes Service (ACK), follow these user-centric instructions:
  1. Access the ACK Console
    : Start by logging into the ACK console.
  2. Navigate to the App Catalog
    : In the left-side pane, navigate to
    Marketplace > App Catalog
    .
  3. Locate ARMS Prometheus
    : On the App Catalog page, switch to the
    Alibaba Cloud Apps
     tab. Here, search for and select
    ack-arms-prometheus
    .
  4. Choose the Cluster & Deploy
    : In the
    ack-arms-prometheus
     section, specify the cluster where you intend to enable ARMS Prometheus. Once selected, proceed to the
    Deploy
     section and initiate the process by selecting
    Create
    .
  5. Establish a Connection
    : Ensure you're connected to the ACK clusters using
    kubectl
    .
  6. Access Cluster Details
    : Re-enter the ACK console and navigate to
    Clusters
     using the left-side pane. Identify and select the cluster you're looking to manage either by clicking on its name or by selecting the
    Details
     option in the
    Actions
     column. This will redirect you to the detailed page of your chosen cluster.
  7. Gather Connection Information
    : Within the
    Cluster Information
     page, navigate to the
    Connection Information
     tab. Depending on your preference, choose the required cluster credentials, be it for online access or a private connection.
>By default,
kubectl
 seeks a
config
 file located in the
$HOME/.kube
 directory of the client. This file holds the necessary credentials for cluster authentication. Ensure that you:
  • Opt between
    Public Access
     or
    Internal Access
     and copy the credentials.
  • Store these credentials within the
    config
     file found in the
    $HOME/.kube
     directory. Save and close the file once done.
  • Validate your connection by executing a
    kubectl
     command, ensuring you've established a successful connection to your cluster.
Accessing Prometheus
: Execute the command below to route Prometheus in the cluster to your local port 9090:
arduinoCopy code
kubectl port-forward svc/ack-prometheus-operator-prometheus 9090:9090 -n monitoring
Finally, launch a web browser and access
localhost:9090
. Within the Prometheus interface, navigate to
Status > Targets
 to view all data collection tasks. A task labeled as
UP
 indicates its successful operation.

Activating ARMS Prometheus via the ACK Console's Prometheus Monitoring Page

If you are seeking to enable ARMS Prometheus through the Prometheus Monitoring section of the ACK console, follow these user-friendly steps:
  1. Access the ACK Console
    : Begin by logging into the ACK console.
  2. Navigate to Clusters
    : From the left-side pane, select
    Clusters
    .
  3. Identify Desired Cluster
    : On the
    Clusters
     page, locate the cluster you wish to work on. Select its name or choose the
    Details
     option in the
    Actions
     column. This action will redirect you to the comprehensive details of your selected cluster.
  4. Access Prometheus Monitoring
    : Within the cluster details, navigate to the left pane and select
    Operations > Prometheus Monitoring
    .
  5. Initiate ARMS Prometheus
    : In the central part of the
    Prometheus Monitoring
     page, select
    Install
     to begin the ARMS Prometheus setup.
