PyXtremIO

PyXtremIO is a python library that can be used to facilitate storage automation of Dell EMC's XtremIO. It uses ReST API to make call to XtremIO's XMS server for storage automation. Portion of this code is adapted from https://github.com/ciarams87/PyU4V. You may get XtremIO XMS's ReST API documentation from https://support.emc.com website.

What Is Supported?

PyXtremIO supports XMS 4.x and 6.0.X

• Current Features:
  • Storage Allocation
  • Storage Deallocation
  • Snapshot Management
• Potential Future Features:
  • Performance Metrics Gathering
  • Alert Management
  • Inventory Discovery

How To Install This Library?

Please run following command to install this library. (You will need GIT CLI & pip3(or pip) installed on your server.)

cd /AnyNewDictory
git clone https://github.com/chiragadm/PyXtremIO
sudo pip3 install .
  

Setting Up PyXtremIO.yaml File For Tracking Logging:

Once this library is installed, you will have an option to create PyXtremIO.yaml file that contains configuration settings to enable rotational logs. Upon appropriate setting in the yaml file, log files will retain any informational or error logs. Please find following example of PyXtremIO.yaml file.

cat PyXtremIO.yaml
---
version: 1
disable_existing_loggers: False
formatters:
    simple:
        format: "%(asctime)s - %(name)s - %(levelname)s - %(message)s"

handlers:
    console:
        class: logging.StreamHandler
        level: DEBUG
        formatter: simple
        stream: ext://sys.stdout

    info_file_handler:
        class: logging.handlers.RotatingFileHandler
        level: INFO
        formatter: simple
        filename: /tmp/PyXtremIO_info.log
        maxBytes: 10485760 # 10MB
        backupCount: 20
        encoding: utf8

    error_file_handler:
        class: logging.handlers.RotatingFileHandler
        level: ERROR
        formatter: simple
        filename: /tmp/PyXtremIO_errors.log
        maxBytes: 10485760 # 10MB
        backupCount: 20
        encoding: utf8

loggers:
    PyXtremIO:
        level: DEBUG
        handlers: [console, info_file_handler, error_file_handler]
        #handlers: [console]
        propagate: no

root:
    level: INFO
    handlers: [console, info_file_handler, error_file_handler]  

You may put this yaml file in direcotry of your choice. By default, this library looks for environment variable called PYXTREMIO_LOG_CFG. This environment variable should contains full path of your PyXtremIO.yaml file. If this environment variable is not set, library will check PyXtremIO.yaml file in our working directory. At last if this file do not exists there, library will use default logging method. This default method will not log your events.

• How To Setup Environment Variable? Please use following procedure to setup environment variable on Unix based systems

export PYXTREMIO_LOG_CFG="/directory/that/contains/file/PyXtremIO.yaml"

Please use following procedure to setup environment variable on Windows systems

set PYXTREMIO_LOG_CFG="\directory\that\contains\file\PyXtremIO.yaml"
