Uptime - IGEL Test

In IGEL deployments, it is essential to monitor the uptime of IGEL Endpoints hosting popular desktop applications in the infrastructure. By tracking the uptime of each of the IGEL Endpoints, administrators can determine what percentage of time an IGEL Endpoint has been up. Comparing this value with service level targets, administrators can determine the most trouble-prone areas of the IGEL deployment.

In some environments, administrators may schedule periodic reboots of their IGEL Endpoints. By knowing that a specific IGEL Endpoint has been up for an unusually long time, an administrator may come to know that the scheduled reboot task is not working on that Endpoint.

This test monitors the uptime of each IGEL Endpoint in the target environment. 

Target of the test : An IGEL Endpoint

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every powered on 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 TCP.

Report By User

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

Report Manager Time

By default, this flag is set to Yes, indicating that, by default, the detailed diagnosis of this test, if enabled, will report the shutdown and reboot times of the virtual desktops in the manager’s time zone. If this flag is set to No, then the shutdown and reboot times are shown in the time zone of the system where the agent is running (i.e., the system on which the remote agent is running).

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG suite 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

Has the thin client been restarted?

Indicates whether this IGEL Endpoint has been rebooted during the last measurement period or not.

Boolean

If this measure shows 1, it means that the IGEL Endpoint was rebooted during the last measurement period. By checking the time periods when this metric changes from 0 to 1, an administrator can determine the times when each IGEL Endpoint was rebooted. 

The detailed diagnosis of this measure helps administrators figure out the exact shutdown date/reboot date, duration for which the endpoint was down and whether/not the endpoint is in maintenance.

Uptime of the thin client during the last measure period

Indicates the time period that this IGEL Endpoint has been up since the last time this test ran.

Secs

If the IGEL Endpoint has not been rebooted during the last measurement period and the agent has been running continuously, this value will be equal to the measurement period. If the IGEL Endpoint was rebooted during the last measurement period, this value will be less than the measurement period of the test. For example, if the measurement period is 300 secs, and if the IGEL Endpoint was rebooted 120 secs back, this metric will report a value of 120 seconds.  The accuracy of this metric is dependent on the measurement period - the smaller the measurement period, greater the accuracy.

Total uptime of the thin client

Indicates the total time that this IGEL Endpoint has been up since its last reboot.

Mins

Administrators may wish to be alerted if an IGEL Endpoint has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions.
