How Do I Fix an Abnormal Agent?
Updated on 2024-09-25 GMT+08:00
Your agent is probably abnormal if it is in Not installed or Offline state. Agent statuses and their meaning are as follows:
- Uninstalled: No agent has been installed on the server, or the agent has been installed but not started.
- Offline: The communication between the agent and the server is abnormal. The agent on the server has been deleted, or a non-Huawei Cloud server is offline.
- Online: The agent on the server is running properly.
Possible Causes
- The agent status on the console is not updated.
The agent status has not been updated. After the agent is installed, it takes 5 to 10 minutes for the console to update its status.
- OS version not supported.
- The network is faulty.
The agent or the cloud protection center is abnormal. For example, the NIC is faulty, the IP address changes, or the bandwidth is low.
- The agent process is abnormal.
Solution
- Check whether the agent status remains Offline on the console for more than 10 minutes after the agent was installed.
- If yes, go to 2.
- If no, wait until the agent goes online. No further action is required. After the agent was installed, it takes 5 to 10 minutes for the console to update its status.
- Check whether your server OS is within the scope of support in "Constraints" in "Service Overview".
- If yes, go to 3.
- If no, the HSS agent cannot be installed or run on your server. Upgrade the OS to a version supported by HSS and try again.
- Check whether the server network is normal.
- If yes, go to 4.
- If no, ensure the security group of your server allows access to port 10180 of the 100.125.0.0/16 CIDR block in the outbound direction and the server can access the network. After the server can access the network, check the agent status.
- Check whether the available memory of the server is greater than 300 MB.
- If yes, go to 5.
- If no, the agent will go offline due to insufficient server memory. After the capacity expansion is complete, the agent will go online again.
- Restart the agent process.
- Windows
- Log in to the server as user administrator.
- Open the Task Manager.
- On the Services tab page, select HostGuard.
- Right-click the service and choose Restart.
- Linux
Run the following command in the CLI as user root to restart the agent:
/etc/init.d/hostguard restart
If the following information is displayed, the restart is successful:root@HSS-Ubuntu32:~#service hostguard restart/etc/init.d/hostguard restart Stopping Hostguard... Hostguard stopped Hostguard restarting... Hostguard is running
After the process is restarted, wait for about 2 minutes.
- If the agent status is Online, no further action is required.
- If the agent status is still Not installed or Offline, uninstall the agent and install it again.
- Windows
