Quickly Building Server Monitoring Capabilities

Scenarios

In the actual O&M process of cloud computing, server monitoring is of great importance. To better monitor servers, you can install the Cloud Eye Agent on cloud servers created from Huawei Cloud public images. Then, you can view visualized server monitoring data and configure alarms for key service metrics. This section uses an ECS as an example to describe how to set alarm rules for CPU usage.

Procedure

Preparations

Purchase an ECS. Check that the ECS is displayed in the server monitoring list on Cloud Eye.

Step 1: Install the Agent on the ECS

Basic, OS, and process metrics of ECSs can be reported. The ECS service reports basic metrics every 5 minutes. You can install the Cloud Eye Agent on ECSs to report OS metrics every minute. Once installed, Cloud Eye reports OS metrics every minute with greater accuracy and detail. For better monitoring, you are advised to install the Agent on your ECSs after you buy them.

The following describes how to install the Agent.

Agent installation methods for Windows and Linux OSs are different.

Step 2: View ECS Monitoring Metrics

1. Log in to the Cloud Eye console.
2. In the navigation pane, choose Server Monitoring > Elastic Cloud Server.
3. Locate the target ECS and click View Metric in the Operation column to view the OS monitoring metrics, basic monitoring metrics, and process monitoring metrics.

Step 3: Create an Alarm Rule to Monitor an ECS

In some regions, Cloud Eye has been upgraded to the latest version. The alarm rule page has been optimized. The upgrade is being rolled out in other regions. For details, see the console. This section describes how to configure alarm rules in the latest version. For details about how to configure alarm rules in the earlier version, see Creating an Alarm Rule (Earlier Version).

After purchasing an ECS, configure an alarm rule to monitor key service metrics of the ECS.

Cloud Eye provides a quick entry for creating alarm rules to monitor ECS or BMS metrics. This step describes how to set parameters for creating an alarm rule. For more information, see Creating an Alarm Rule to Monitor a Server.

1. On the Server Monitoring page, locate an ECS and choose More > Create Alarm Rule in the Operation column.
   Figure 7 Server monitoring list
   
2. On the Create Alarm Rule page, the basic information is pre-filled by default. Configure alarm policy parameters as prompted and select an existing alarm template.

3. Configure alarm notifications. For details, see Creating an Alarm Rule.

   Table 1 Alarm notification parameters

   Parameter	Example Value	Description
   Alarm Notifications	Enabled	Whether to send an alarm notification when an alarm is triggered.
   Notified By	Topic subscriptions or Account contact	Select a notification method and recipients. You can select notification policies, contact groups, or topic subscriptions. If you select Account contact, notifications will be sent to the mobile number and email address specified during registration.
   Notification Window	00:00–23:59	If you select Contact groups or Topic subscriptions for Notified By, you need to set the notification window. The system sends notifications only within the notification window.
   Trigger Condition	Generated alarm and Cleared alarm	This parameter is available when Notified By is set to Contact groups or Topic subscriptions. You can select Generated alarm, Cleared alarm, or both.
   Notification Template	System template	This parameter is only available if you set Notified By to Contact groups or Topic subscriptions. You can select an existing template or create one to send alarm notifications.

4. After the configuration is complete, view the alarm rule in the alarm rule list.

Step 4: View Alarm Records

After receiving an alarm notification, you can search for the alarm in the alarm records by resource ID.

Follow-up Operation: Masking Alarm Notifications

If you do not need to receive notifications after an alarm is triggered, you can set a rule to mask the alarm notifications. After the masking rule is applied, only alarm records are generated.

1. Log in to the Cloud Eye console.
2. In the navigation pane, choose Alarm Management > Rule Settings.
   

   In some regions, the path is Alarm Management > Alarm Rules.

3. On the Alarm Rules page, locate the row containing the alarm rule to be masked, click More in the Operation column, and select Mask Alarm. In the displayed dialog box, configure Alarm Masking Duration and click OK.
