1. Introduction to cloud monitoring service CES

Cloud Eye is a monitoring platform for Huawei cloud resources, providing real-time monitoring, timely alarms, resource grouping, site monitoring and other capabilities. Protect your cloud business and be your personal steward of cloud resources.

2. Introduction to this practice

1. Introduction to this practice

This experiment is based on the ECS environment and introduces how to use the cloud monitoring service CES to perform ECS monitoring related operations. Including monitoring of main CPU usage, disk read bandwidth, disk read IOPS, disk write IOPS, inbound bandwidth, outbound bandwidth, inbound traffic, outbound traffic, etc., as well as message notifications on the use of SMN services.

2. Directory of this practice

Be familiar with Huawei Cloud CES related operations
Be familiar with the related operations of Huawei Cloud SMN

3. Purchase Huawei Cloud ECS cloud server

1. Enter the ECS cloud server console

In the service list - elastic cloud server

2. Purchase ECS cloud server

Basic configuration

Choose to purchase an elastic cloud server,
Region: North China - Beijing IV
Billing mode: On-demand billing
Availability Zone: Availability Zone 1
CPU architecture: x86
Specifications: General Computing Enhanced, c7.large.2
Mirror selection: centos7.6 version
The rest of the configuration can be defaulted.

Network Configuration

Select the default private cloud VPC and security group, or choose to create your own VPC and security group independently.
Flexible public network: Choose to buy now
The rest of the configuration can be freely selected according to your own needs.

Advanced configuration

Set the login password for the elastic cloud server and leave the rest of the configuration as default.

Confirm configuration and purchase

Check and confirm the configuration information of ECS and confirm the purchase.

3. Check the status of the ECS elastic cloud host

In ECS Controller, check the ECA elastic cloud host status.

4. Monitor ECS elastic cloud host performance

1. Connect to ECS remotely

Open Terminal through the "Xfce Terminal" on the experimental desktop and connect using the elastic public IP of ECS.

connection command

LANG=en_us.UTF-8 ssh root@EIP

2. Enter the cloud monitoring service CES page

Service list->"Management and Monitoring"->"Cloud Monitoring Service CES", enter the "Cloud Monitoring Service CES" page

3. Use the cloud monitoring service CES interface

In the monitoring overview interface, check the host monitoring. At this time, it is found that there is no monitoring data. You need to install the Agent monitoring plug-in on the ECS server to display the data.

4. Install the Agent monitoring plug-in

Execute the following command to install the Agent monitoring plug-in.

cd /usr/local && curl -k -O https://obs.cn-north-4.myhuaweicloud.com/uniagent-cn-north-4/script/agent_install.sh && bash agent_install.sh

5. Edit the test script

Enter the following command and shell script in the Xfce terminal.

[root@ecs-67a3 local]# cd ~
[root@ecs-67a3 ~]# vim test.sh
[root@ecs-67a3 ~]# cat test.sh 
#/bin/bash
a=1
while true
do
a=$(($a+1))
echo $a
sleep 0.01
done
[root@ecs-67a3 ~]#

6. Execute the test shell script

Execute test shell script

sh test.sh

7. Return to the cloud monitoring service CES page

Wait for 5-10 minutes (it takes a certain amount of time to collect data), return to the "Cloud Monitoring Service CES" page, click on the ECS name to enter the monitoring page.
In the basic monitoring module, you can see the fluctuations in cloud disk read and write, as well as network inlet and outlet traffic and other information.

8. Shell script to stop ECS running

Enter the ctrl+z command in the Xfce terminal to stop the running program.

5. Collection of CES indicators

1.Set alarm rules

On the cloud monitoring service page, click "Alarm Notification" under "Alarm" and click "Create Notification Group"

Enter the group name (the name can be customized) and click OK to create the notification group

2. Create alarm rules

Name: alarm-test
Resource type: Elastic cloud server
ECS dimension: cloud server
Monitoring scope : Specify resources, check the previously created ECS
Trigger rule: Custom creation
Alarm policy: CPU usage, the maximum value is within 5 minutes of the monitoring period> ;=0.5% and for 1 consecutive cycle, the alarm will occur every 5 minutes
Notification method: Notification group Notification group: myecs
Effective time: Default
Trigger condition: Default

After selecting the parameters, click "Create Now" to return to the "Alarm Rules" page, where you can view the created alarm rules.

3. Test trigger alarm

Enter the following command in the Xfce terminal

cd ~
sh test.sh

4. View alarm records

After waiting for 5-10 minutes (it takes a certain amount of time to collect data), return to the "Cloud Monitoring Service CES" page, click "Alarm Rules" under "Alarms", and click "Alarm Record".

5. Stop the program running on ECS

Enter the ctrl+z command in the Xfce terminal to stop the running program

6. Actual deployment operations of SMN and CES

1. Introduction to SMN services

The message notification service (Simple Message Notification) provides users with fast and easy, stable and reliable, simplified operation and maintenance, highly scalable, safe and trustworthy message notification capabilities. End users can receive notification information through HTTP, HTTPS, email, SMS, trigger function execution, instant messaging tools, etc. Huawei Cloud users can also use message notification services to integrate application functions between applications to reduce system complexity.
