The general guidelines for writing
Python scripts to run under SLX-OS are as follows:
About this task
- Although previous experience programming in Python is helpful, experience in other high-level languages is enough to get you started with simple Python scripts.
- The Python developer either needs experience with
SLX-OS CLI or access to a resource with such experience.
- To help decide which editor or integrated
development environment (IDE) to use, refer to http://www.python.org.
- Make sure that the appropriate version of the
Python interpreter is installed on your development computer. For the current
version of SLX-OS, install Python 3.5.2.
- Make sure that in the
Extreme SLX-OS Command Reference you are familiar with the
python and the
CLI( ) topics.
- The script must include
from CLI import CLI.
This enables the CLI(
) command, by which Python can interact with SLX-OS.
- Write the Python script and save it, with a
.py suffix. Valid filenames range from 4 through 32 characters (including the suffix). The first character must be alphabetic.
Guidelines for RASLOG event-handler
scripts
The additional guidelines for writing RASLOG event-handler scripts are as follows:
- The script must include
import
json.
- If an event-handler detects
the log messages specified in the triggers and the trigger-function
conditions are met, the script is executed. As part of this execution, the
script is passed a
--raslog-triggers argument with JSON-formatted dictionary
containing the relevant message identifiers (MSGID) as keys and the message
text as values.
- If the trigger-function is
OR, only a single MSGID and message text are present.
- If the trigger function is
AND, all relevant MSGIDs and messages are passed inside the json data
structure.
