Adding stress test script

[dwang3851]

Adds a script for basic stress test functionality. This script uses the Tango CLI to simulate various submissions scenarios. The number of submissions can be adjusted as well as the rate at which they are submitted. Required parameters include the autograder image, the path to the Tango directory, the job name, and the path to the job.

Example command to run script:

• python3 stressTest.py --num_submissions 10 --submission_delay 1.0 --autograder_image autograding_image_py --tango_port 4567 --tango_path ~/Tango --job_name assessment1 --job_path ~/Tango/clients/job1/

To get metrics, simply add --get_metrics True to the end of this command, this will not spawn any new jobs.

Walkthrough

The changes introduced in this pull request consist of the addition of a new script, stressTest.py, which facilitates stress testing using the Tango framework. This script includes two main functions: run_stress_test, which submits jobs to the Tango CLI, and get_metrics, which retrieves job completion metrics from a log file. Additionally, the worker.py file has been updated to enhance logging and error handling within the Worker class, improving the tracking of job execution and failure scenarios.

Changes

File	Change Summary
stressTest.py	Introduced a new script with two functions: run_stress_test for submitting jobs with parameters and logging, and get_metrics for retrieving job completion metrics from a log file. Includes command-line argument parsing.
worker.py	Enhanced logging and error handling in the Worker class. Added start_time for tracking job duration, improved error logging in rescheduleJob, and refined exception handling in notifyServer.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
