If the private DNS configuration of the Cloud Virtual Machine (CVM) is incorrect, the Agent will fail to be downloaded and monitoring components will fail to report data. For more information on the private DNS configurations of Tencent Cloud CVMs, see Private network access.
The installation on Windows is automatic. The installer automatically exits after installation. If you want to view the prompt during installation, run the installer in CLI mode.
After the installation is complete, the sgagent process will start first, followed by the barad_agent process to be launched within 5 minutes. Before installation, check whether the disk partition where the installation directory resides is full, whether inode is full, whether the write permission has been granted, and whether the network is normal.
If the network is normal, users can view the monitoring data at the frontend 5 minutes after the barad_agent process is started.
Run the uninstallation script in the
admin sub-directory under the Agent installation directory to automatically uninstall Agent.
/usr/local/qcloud/monitor/barad/admindirectory, run the stop.sh script to stop Agent, and then run the trystart.sh script to start Agent.
If you see a yellow exclamation mark (!) on the monitoring list page in Cloud Monitor > Cloud Product Monitor > Cloud Virtual Machine, log in to the CVM and check if Agent is running. If Agent is running properly, the reported failure may be caused by a network error, and the backend fails to detect the Agent status of the CVM, and a yellow exclamation mark (!) is displayed in the console. In this case, you can try enabling the firewall. If the problem persists, you can Submit Ticket or contact customer service for troubleshooting.
Troubleshoot the problem by referring to CVM has no monitoring data.
