Endpoint Performance - IGEL Test

High network latencies, poor signal strength, or packet losses during transmission can cause significant slow-downs in the request processing capability of IGEL Endpoints. Hence, monitoring latencies between the IGEL Endpoints and individual client terminals is important.

Using this test, an administrator can identify user sessions that are being impacted by high latencies or by excessive packet drops. In some cases, an IGEL Endpoint may regard a user session as active, even though the network link connecting the user terminal to the IGEL Endpoint was disrupted and failed. The Endpoint Performance - IGEL test alerts administrators to such situations. In addition, this test also reports the signal strength and quality of WiFi network accessed by the IGEL Endpoints.

Target of the test : An IGEL Endpoint

Agent deploying the test : A remote agent

Outputs of the test : One set of outputs for every user currently connected to the IGEL Endpoint

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The nick name of the IGEL Endpoints component for which this test is to be configured.

Port

Refers to the port at which the specified host listens to. By default, this is NULL.

Inside View Using

To obtain the 'inside view' of performance of the IGEL Endpoints - i.e., to measure the internal performance of the IGEL Endpoints - this test uses a light-weight Endpoint Agent software deployed on each of the IGEL Endpoints. The Endpoint Agents collect performance metrics from the IGEL Endpoints and communicate the metrics to the eG remote agent using TCP protocol. Accordingly, by default, this parameter is set to eG VM Agent.

Report By User

Since this test runs for an 'IGEL Endpoints' component, this flag is set to No by default.

Report Powered OS

Since this test runs for an 'IGEL Endpoints' component, this flag is set to Yes by default.

Is Cloud VMs

Since this test runs for an 'IGEL Endpoints' component, this flag is set to Yes by default.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. For instance, if you set to 1:1, it means that detailed measures will be generated every time this test runs, and also every time the test detects a problem.

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.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total devices connected to local router

Indicates the number of IGEL Endpoints connected to the local router.

Number

This measure is only applicable for Summary descriptor.

Wi-Fi signal strength

Indicates the signal strength of the WiFi network accessed by this IGEL Endpoint.

 

By default, the Endpoint Agent executes the netsh wlan show interface command on the IGEL Endpoint to determine the WiFi signal strength and the quality of the signal. eG Enterprise determines the WiFi signal strength based on the signal quality range determined upon execution of the command. 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.

Wi-Fi signal quality

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

Percent

A high value is preferred for this measure.

Local router latency

Indicates the time taken by the local router to respond to the requests made by this IGEL Endpoint.

Milliseconds

A high value is a cause for concern, as it indicates a potentially latent function. The detailed diagnosis of this measure reveals the IP address of the local router.

Local router packet loss

Indicates the percentage of packets lost during data exchange between this IGEL Endpoint and the local router.

Percent

 

ISP latency

Indicates the time taken by the ISP (Internet Service Provider) to respond to the requests made by this IGEL Endpoint.

Milliseconds

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

The detailed diagnosis of this measure reveals the IP address of the Internet Service Provider.

ISP packet loss

Indicates the percentage of packets lost during data exchange between this IGEL Endpoint and the ISP (Internet Service Provider).

Percent

 

Internet latency

Indicates how long this IGEL Endpoint waited to get response from internet.

Milliseconds

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

Internet packet loss

Indicates the percentage of packets lost during data exchange between this IGEL Endpoint and the internet.

Percent

 

Cloud gateway latency

Indicates how long this IGEL Endpoint waited to connect to the IGEL Cloud Gateway.

Milliseconds

 

Cloud gateway packet loss

Indicates the percentage of packets lost during data exchange between this IGEL Endpoint and the IGEL Cloud Gateway.
