No Monitoring Data Is Displayed After One-Click Restoration Performed for the Agent

Symptom

The Agent is running normally after being restored, but no monitoring data is generated.

Constraints

The restoration method in this section only supports new Agent version. If your Agent is of an earlier version, you are advised to upgrade it to the new version.

Run the following command to check the current Agent version:

if [[ -f /usr/local/uniagent/extension/install/telescope/bin/telescope ]]; then /usr/local/uniagent/extension/install/telescope/bin/telescope -v; elif [[ -f /usr/local/telescope/bin/telescope ]]; then echo "old agent"; else echo 0; fi

Possible Causes

If no OS monitoring data is available for an ECS or BMS with the Agent installed, the possible causes are as follows:

• There is a problem with the Agent process.
• There is a problem with agency configurations.
• The network is not well connected.

Procedure (Linux)

1. Log in to the ECS or BMS as the user root.
2. Run the following command to check whether the telescope process is running:

   ps -ef |grep telescope

   If following information is displayed, the telescope process is normal.

   • If the telescope process is normal, go to 4.
   • If the telescope process is abnormal, go to 3.
3. Run the following command to start the Agent:

   service uniagent restart

4. Run the following command to check whether the required agency has been created:

   curl -ivk https://agent.ces.myhuaweicloud.com/v1.0/agencies/cesagency/securitykey

   • If data is returned, the agency is normal and AK/SK can be obtained. No further action is required.
   • If the request fails or the following information is displayed, go to 5.

5. On the IAM console, in the left navigation pane, choose Agencies, and search for cesagency. Expand the cesagency details, check whether the current region is included in Project [Region]. If no, in the Operation column, click More, and choose Manage Permissions. Click Assign Permissions, search for CES Administrator, click the drop-down list box, and select the current region.

   • If the problem is resolved, no further action is required.
   • Otherwise, go to 6.
6. Run the following command to check whether the DNS service is normal:

   ping agent.ces.myhuaweicloud.com

   • If the network is normal, no further action is required.
   • Otherwise, modify the DNS server address or the Cloud Eye endpoint.
     

     For details about Cloud Eye endpoints for each region, see Regions and Endpoints.

Procedure (Windows)

1. Log in to the ECS or BMS as an administrator.
2. Open the Task Manager and check whether the telescope process is running.

   If there are Figure 5 and Figure 6, the telescope process is running.

   • If the process is normal, go to 4.
   • If the process is abnormal, go to 3.
3. Double-click start.bat in C:\Program Files\uniagent\script to start the Agent.
4. On the IAM console, in the left navigation pane, choose Agencies, and search for cesagency. Expand the cesagency details, check whether the current region is in Project [Region]. If no, in the Operation column, click More, and choose Manage Permissions. Click Assign Permissions, search for CES Administrator, click the drop-down list box, and select the current region.
