Suggestion: Handle problems based on alarm details.

Alarm

If a critical or major alarm exists, the resource status is Alarm.

Suggestion: Handle problems based on alarm details.

Silent

If the ICAgent fails to collect resource metrics, the resource status is Silent. The causes include but are not limited to:

• Cause 1: The ICAgent is abnormal.

  Suggestion: In the navigation pane, choose Configuration Management > Agent Management. On the page that is displayed, check the ICAgent status, as shown in Figure 1. If the status is not Running, the ICAgent is uninstalled or abnormal. For details about how to solve the problem, see Table 1.

  Table 1 ICAgent troubleshooting suggestions

  Status	Suggestion
  Uninstalled	Install the ICAgent according to Installing the ICAgent (Linux).
  Installing	Wait for 1 minute to install the ICAgent.
  Installation failed	Uninstall the ICAgent according to Uninstalling the ICAgent Through Logging In to the Server and then install it again.
  Updating	Wait for 1 minute to upgrade the ICAgent.
  Upgrade failed	Uninstall the ICAgent according to Uninstalling the ICAgent Through Logging In to the Server and then install it again.
  Offline	Ensure that the Access Key ID/Secret Access Key (AK/SK) and Elastic Cloud Server (ECS) agency configurations are correct.
  Faulty	Submit a service ticket according to Submitting a Service Ticket.

• Cause 2: Application Operations Management (AOM) cannot monitor the current resource.

  Suggestion: Check whether your resources can be monitored by AOM. Specifically, AOM can monitor hosts, Kubernetes containers, and user processes, but cannot monitor system processes.

• Cause 3: The local time of the host is not synchronized with the NTP server time.
  

  NTP Sync Status: indicates whether the local time of the host is synchronized with the NTP server time. The value can be 0 or 1. 0 indicates the synchronized status while 1 indicates the asynchronized status.

  Suggestion: In the navigation pane, choose Monitoring > Metric Monitoring, and check the NTP Sync Status metric of the host, as shown in Figure 2. If the value of NTP Sync Status is 1, implement synchronization according to Does HUAWEI CLOUD Provide the NTP Server and How Can I Install It?

• Cause 4: The resource is deleted or stopped.

  Suggestion:

  • On the ECS page, check whether the host is restarted, stopped, or deleted, as shown in Figure 3.

  • On the Cloud Container Engine (CCE) page, check whether the service is stopped or deleted, as shown in Figure 4.

  • If an application discovery rule is disabled or deleted, the application discovered based on the rule will also be disabled or deleted. On the AOM page, check whether the application discovery rule is disabled or deleted, as shown in Figure 5.
