System Health - Chrome OS Test

Monitoring and maintaining the system health of devices in the Google Chromebooks Group is a proactive approach to maintain reliability, performance, and security of the devices. This ensures that devices are running efficiently, reduces the risk of unexpected failures, and enhances the overall user experience. Using the System Health - Chrome OS test, administrators can monitor the current status, CPU utilization, whether/not the OS is updated, battery health and capacity of each device.

Target of the Test : Google Chromebooks Group

Agent deploying the test: A remote agent

Output of the test: One set of results for each device in the target Google Chromebooks Group

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed. By default, this is set to 5 minutes.

Host

The host for which the test is to be configured.

Customer ID

 

Private Keyfile Name

To connect to the Google Chromebooks Group, the eG agent requires a private key of a service account with Compute Viewer, Monitoring Viewer, and Cloud Asset Viewer roles in the target project. If a service account pre-exists in the project, then you can download the private key as a JSON file. Save this JSON file in the <eG_Install_Dir>/agent/lib folder and provide the name of that file against this parameter. However, if no such service account pre-exists, you will have to create one for monitoring the project. To know how to create a service account and download its private key, refer to How does eG Enterprise Monitor Google Chromebooks Group? topic.

Proxy Host and Proxy Port

In some environments, all communication with the Google Chromebooks Group be routed through a proxy server. In such environments, you should make sure that the eG agent connects to the devices in the group via the proxy server and collects metrics. To enable metrics collection via a proxy, specify the IP address of the proxy server and the port at which the server listens against the Proxy Host and Proxy Port parameters. By default, these parameters are set to none, indicating that the eG agent is not configured to communicate via a proxy, by default.

ProxyUsername, ProxyPassword and Confirm Password

If the proxy server requires authentication, then, specify a valid proxy user name and password in the Proxy Username and Proxy Password parameters, respectively. Then, confirm the password by retyping it in the Confirm Password text box.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measures made by the test
Measurement Description Measurement Unit Interpretation

CPU utilization

Indicates the percentage of CPU utilized by this device.

Percent

A value close to 100% is a cause for concern.

Heartbeat status

Indicates the current heartbeat status of this device.

 

The table below indicates the values that this measure can report and their corresponding numeric equivalents along with the signal quality range:
