The goal of netlasso is to create a automation tool designed to test network bandwidth while gathering system and hardware data. By using both tcp and udp tests, netlasso can help clarify the best protocol and rate to send data over a link. Netlasso reports the test results in a number of files and statistically analyzies the data. Netlasso is developed in Python and does not require root access nor does it need to be compiled. This tool uses point to multipoint in a client server model where the client connects to servers to run application and networking tests. The tool that generates the data to send by using nuttcp and iperf, but furthers its capabilities by running multiple tests while gathering system information. Later implementations of netlasso will use newer protocols such as rbudp and LamdaStream as well as offer a data archiving format that can later generate rrd graphs.
I'll explain the configuration file by including a sample from the default config.
[global]You should make sure you define the hosts before you make refrence for them in the [global] section.
There are a few flags such as verbose (-v) and brief (-b).
I would always suggest running the program with the brief tag, as it provides you with a summary of the tests in progress. It also provides you with a statistically analized output file.
The verbose flag will give you a lot of information going on. If you are really interested in observing the testing, turn on both the brief and verbose flags.
The logs will be generated by timestamps. If you select the brief option 2 logs will be created. One log will contain all the raw data and the other will contain system and statistical data.
