A python tool for simplifying collection of measurements over repetitive tasks
Project description
roBob is python automation tool that simplifies the collection of measurements over repetitive tasks, and the automatic creation of reports.
Do you have to run some benchmarks? Do you need to run some tasks over night and collect the numbers? Are you using custom solutions to achieve this? Robob helps you achieve this in every environment! It launches your application on a virtual terminal, starts your application, cralws it’s output, collects numbers and creates reports for you!
It uses a powerful, extensible, human-readable YAML ruleset for defining your specifications.
You can learn more on the Wiki Page: https://github.com/wavesoft/robob/wiki !
Installing
Robob is available on PyPI so you can install it with pip:
pip install robob
Usage
To launch a benchmark you only need to specify the path to the specifications file you want to use:
robob benchmarks/mybenchmark.yaml
Example
The following specification file from the Simple Example (https://github.com/wavesoft/robob/wiki/Simple-Example) demonstrates how to use roBob to run iperf between two machines for different window sizes:
# What metrics we will be tracking
metrics:
- name: bandwidth
units: "B/s"
# Which test cases are we going to run
test-case:
window_size: [ 64, 128, 256, 512, 1024, 2048 ]
# Which nodes are involved on this test
nodes:
- name: node1
host: 192.168.1.1
access:
- class: robob.access.ssh
username: user
password: secret
- name: node2
host: 192.168.1.2
access:
- class: robob.access.ssh
username: user
key: /path/to/private_key
# What application(s) to start
apps:
- name: iperf_server
binary: /usr/bin/iperf
args: [ "-y", "C", "-s", "-w", "${window-size}" ]
parser: iperf_parser
- name: iperf_client
binary: /usr/bin/iperf
args: [ "-y", "C", "-c", "${remote}", "-w", "${window-size}" ]
parser: iperf_parser
# How to parse their output
parsers:
- name: iperf_parser
class: robob.parser.split
separator: "," # Split on commas
match:
- col: 8 # Get the 9th column (0=first)
name: bandwidth # And put it on the bandwidth metric
# Which streams to open in order to run the test
streams:
- node: node1 # On node 1
app: iperf_server # Start iperf server
- node: node2 # On node 2
app: iperf_client # Start iperf client
delay: 5s # After 5 seconds
# We also need to define the '${remote}' macro
# to point on the IP address of the server
define:
remote: "${node1.host}"
