Health Overview

Before using this function, ensure that the current administrator has the read and write permissions of the health check function. If the administrator does not have the required permissions, the system administrator must grant the permissions to the administrator.

Log in to the web UI as the system administrator, choose System > Administrator > Administrator Role, click Edit, and change the Monitor > Heath Check permission under Permission to Read/Write. The system administrator has the read and write permissions by default. Therefore, this step can be skipped for the system administrator.

After networking planning and configuration on the device are complete, you can perform health check for the device.

1. Choose Health Overview and click Check Now. In the Configure Check Item dialog box that is displayed, select the check items and click OK to start check. The check results, including the health index, are displayed.

   

   In the scenario of server or network detection under network and service health, the device can perform health check only based on the route query result. It does not support health check if users specify the source IP address, source interface, or server where the VPN instance is configured.

   The health index is the weighting coefficient multiplying by the average value of four-dimension scores. The weighting coefficient is determined by the lowest score. That is, the weighting coefficient is 1 for 100 points, 0.9 for 80 to 99 points, 0.8 for 60 to 79 points, and 0.7 for 59 points and less.

   The total health index score is calculated using this formula: S = (S1 + S2 + S3 + S4)/4 x W. In this formula, S indicates the total score; Si (i = 1, 2, 3, or 4) indicates the score of each dimension. W indicates the weighting coefficient of the dimension with the lowest score.

2. Click Fix Issues. In the Health Check dialog box displayed, view details about the hardware, network, service, resource usage, and signature database update, and troubleshooting suggestions. You can optimize the device based on the handling suggestions.
