Network Details - Chrome OS Test

High network latencies, poor signal strength, weak network link connection unavailability or high traffic during transmission/reception can cause significant slow-downs in functions of the applications running on the devices. Hence, monitoring signal strength, speed and quality of the Wifi network, traffic flow and connection availability between the devices and network is important to ensure better user experience on the devices. Using this test, an administrator can instantly identify poor network strength/quality, high latency, connection unavailability and excessive data flow over the network.

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	To enable the eG agent to communicate to the devices managed by the target Google Chromebooks Group within the Google Workspace console and make REST API calls to collect metrics, the tests should be configured with the customer ID. To know how to obtain the customer ID mapped to the organization to which the target Google Chromebooks Group is mapped fron the Google Workspace console, refer to How does eG Enterprise Monitor Google Chromebooks Group? topic.
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.
Proxy Username, Proxy Password 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

Wi-Fi signal strength

Indicates the signal strength of the WiFi network accessed by this device.

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

Measure value	Numeric Value	Signal Quality Range
Poor	0	0
Weak	1	1%-25%
Fair	2	26%-50%
Good	3	51%-75%
Excellent	4	Above 75%

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the Wi-Fi signal strength. However, in the graph of this measure, signal strength will be represented using the corresponding numeric equivalents only - i.e., 0 to 4.

The detailed diagnosis of this test reveals the LAN IP address, gateway IP address and signal strength of the Wifi network accessed by the Chromebook.

Connection state

Indicates the current network connection state 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:

Measure value	Numeric Value
Unspecified	0
Connected, internet available	1
Connected, internet may not be available	2
Connected, internet may be limited	3
Connecting	4
Connected	5

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the connection state. However, the graph of this measure will be represented using the corresponding numeric equivalents only - i.e., 0 to 5.

Connection type

Indicates the current network connection type 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:

Measure value	Numeric Value
Network connection type unspecified	0
Cellular network connection	1
Ethernet network connection	2
Tether network connection	3
VPN network connection	4
Wi-Fi network connection	5

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the connection type. However, the graph of this measure will be represented using the corresponding numeric equivalents only - i.e., 0 to 5.

Network data transmitted

Indicates the amount of data transmitted through the network accessed by the device.

Mbps

Network data received

Indicates the amount of data received through the network accessed by this device.

Mbps

Wi-Fi link quality

Indicates the percentage of signal strength of the WiFi network accessed by this device.

Percent

A high value is preferred for this measure.

HTTP latency

Indicates how long the device waited to get response for the HTTP requests.

Seconds

A high value is a cause for concern, as it indicates a potentially latent function.

Download speed

Indicates the rate at which data was downloaded over the network accessed by this device.

Kbps

A low value for this measure is a cause for concern.
