Site Sonar Job Submission Tool

This repository contains the source code for a Site Sonar Job Submission Tool. This tool is used to automate the submission of jobs to the WLCG to analyse the Grid site information.

Prerequisites:

Please make sure following prerequisites are met before starting the program.

  • Start a MySQL instance and source the db.sql SQL file to create the database
  • Update the database configurations and grid configurations in config.py
  • Update the job script with your desired commands
  • Enter the xjalienfs environment
  • Start Site Sonar MonAlisa client

Updating the Job Script

  • The job script is available at scripts/stat.py
  • Make sure you change only the monitors variable in the job script
  • The monitors is a python dictionary of the following format

monitors = { identifier : command, identifier : command } The identifier will be used as the key when searching the collected information

Running the Program

If you are running the tool on a local instance, initialized the database using python3 site-sonar.py init

This command is intended to be used only for development purposes. It will be removed in the future. Run only once.

Use the command python3 site-sonar.py submit to start job submission

The job results will be added to the database by Site Sonar MonAlisa client.

A full grid run will take around 36 hours. Therefore use nohup <command> & to run the submit command

Aborting a Run

If you want to abort the current run use the command python3 site-sonar.py abort

If the tool is running in the background, make sure to bring it to the foreground before using the above command

If you abort a run, its data will not be available for searching

If you want to abort the run while preserving the collected results, use --clean flag. clean flag kills the remaining jobs and update the processing states of the sites and the run.

python3 site-sonar.py abort --clean

If the run has completed and you want to kill the remaining jobs, use --finish flag. finish flag kills the remaining jobs without changing any processing states.

python3 site-sonar.py abort --finish

Finishing a Run

The run will be marked as COMPLETED if any of the following conditions are met.

  • All the Grid Sites are marked as STALLED or COMPLETED

A Grid site will be marked as COMPLETED if 90% of the jobs submitted to it have finished the excution. A Grid site will be marked as STALLED if none of its jobs have run since 12 hours from the last job execution.

  • The run will be marked as TIMED_OUT if none of the jobs have completed since 24 hours from the last job execution

A COMPLETED or TIMED_OUT run is considered as a finished run and its data will be available for search in the website.

  • There is a possibility that the run won't meet either of the above conditions. The run will have to be manually marked as TIMED_OUT in such a case. Use the command python3 site-sonar.py abort --clean for this.

The remaining jobs will be killed when abort command is used

Starting a New Run

  • To start a new run, start a fresh environment by using the command python3 site-sonar.py reset
  • Submit the jobs using python3 site-sonar.py submit

Obtaining a Run Analysis

  • To get a summary of all the runs, use python3 site-sonar.py summary
  • To get a summary of a specific run, use python3 site-sonar.py summary -r <run_id>

Query Results

You can either use the Site Sonar website or the CLI tool to query the collected results. Use the following command to search the results. ./site-sonar.py search -r <run_id> -q A="<identifier>: <value>" -eq "<relationship among queries>"

  • To add multiple queries use the format <next_english_letter>="<identifier>: <value>"
  • Define the relationship as a boolean expression A & ( B | ~C) (Only the english letter in order the symbols [&,|,~,(,)] are allowed)

./site-sonar.py search -r 1 -q A="Singularity: SUPPORTED" -q B="Max Namespaces:15000" -eq "A | B"
