Linux Systems Test

This test reports the number and names of Linux systems for which the VM agents reported metrics during the last hour. Additionally, the test also reveals those systems that are currently powered-on, and those systems that have users logged into them currently. This way, administrators can quickly identify the powered-off systems and those that are not in use currently.

Target of the test : A Linux Systems Group

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every Linux system

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed.
Host	The nick name of the Linux Systems Group 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 systems - i.e., to measure the internal performance of the systems - this test uses a light-weight eG VM Agent software deployed on each of the systems. Accordingly, this parameter is by default set to eG VM Agent.
Report By User	This flag is set to No by default. This implies that the Linux systems in environments will always be identified using the system name. In other words, this test will, by default, report measures for every systemname. On the other hand, if you want this test to report the measures for every user on a system, then set this flag to Yes. In such a case, this test will report the measures for every username_on_systemname.
Report Powered OS	By default, this flag is set to Yes, then the 'inside view' tests will report measures for even those Linux systems that do not have any users logged in currently. The systems will be identified by their name and not by the username_on_systemname. On the other hand, if this flag is set to No, then this test will not report measures for those systems to which no users are logged in currently.
Is Cloud VMs?	This flag is set to Yes by default. The value of this flag cannot be changed. This implies that the cloud-based Linux systems in environments will always be identified using the login name of the user. In other words, in cloud environments, this test will, by default, report measures for every username_on_systemname.
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 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
Total systems reported in the last one hour	Indicates the total number of systems in the target Linux Systems Group that reported measures in the last one hour.	Number	The detailed diagnosis of this measure if enabled, provides the name and IP address of the Linux system, the operating system on which the system is running, public IP address of the system and country, region and city from which the system is accessed.
Currently powered on systems	Indicates the number of systems that are currently powered on in the target group.	Number	The detailed diagnosis of this measure if enabled, provides the name and IP address of the Linux system, the operating system on which the system is running, public IP address of the system and country, region and city from which the system is accessed.
Systems with users	Indicates the number of powered on systems with users logged in.	Number	The detailed diagnosis of this measure if enabled, provides the name and IP address of the Linux system, the operating system on which the system is running, public IP address of the system and country, region and city from which the system is accessed.
Systems without users	Indicates the number of powered on systems without any users logged in.	Number
Overall Systems reported for this component	Indicates the total number of systems in the target group.	Number
Systems reporting currently	Indicates the number of systems that are currently reporting measures.	Number	The detailed diagnosis of this measure if enabled, provides the name and IP address of the Linux system, the operating system on which the system is running, public IP address of the system and country, region and city from which the system is accessed.
Systems not reporting currently	Indicates the number of systems that are not currently reporting measures.	Number	The detailed diagnosis of this measure if enabled, provides the name and IP address of the Linux system, the operating system on which the system is running, public IP address of the system and country, region and city from which the system is accessed.
