Network

Features

Germain monitors Network performance following 2 approaches: via Germain Engine that monitors performance of Network Devices on a hardware or via Germain RUM (extension or js) that monitors performance of Network Interface from a browser 

Configure

Via Germain Engine

Create target server

1. Germain Workspace > Left Menu > Data Source > Add server (...)

Create Network Monitor Instance

1. Germain Workspace > Left Menu > Wizards > Network Monitor 

2. Select Source Server from the drop-down list (This is the server the component will run)

3. Select the target server that we created in previous steps

4. Provide the Monitor Name or use the default name

5. Select Monitoring node and Engine from the drop-down list

6. Set a schedule for how often this component should run

7. If this component will run through SSH, provide credentials for SSH connection

8. Click Next

9. Provide value for threshold (e.g. If 10s is provided, any result that has a response time of greater than 10s will trigger this SLA)

10. Choose or skip Portlet style

11. Choose the dashboard where the Portlet will be added.

12. Click Finish

Via Germain RUM

This applies to both Germain RUM Browser Extension or Javascript.

SLA

The following line can be added to the Germain RUM’s initScript to modify the list of poor grades (i.e. what is considered "poor network"):

settings.plugins.poorNetworkLocation.poorGrades = ['slow-2g', '2g', '3g'];

e.g. '3g' can be removed so only 2g and below are considered poor.

Data Model

KPI: UxMetric

• Type: [Browser:Poor Network]

• Value: [DownlinkMbps] - The values of 'slow-2g', '2g', '3g', and '4g' are determined using observed round-trip times and downlink values.

• Name: [NetworkGrade]

• Location: [LocationDimension]
