Network Packet Traffic - OS Test

This is an internal test that monitors the incoming and outgoing traffic through each Linux system in the target Linux Systems Group.

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 systemname:network_interface combination

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.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Incoming network traffic	Indicates the rate of incoming traffic.	Pkts/Sec	An increase in traffic to the system can indicate an increase in accesses to the system (from users or from other applications) or that the system is under an attack of some form.
Outgoing network traffic	Represents the rate of outgoing traffic.	Pkts/Sec	An increase in traffic from the system can indicate an increase in accesses to the system (from users or from other applications).
