SACCT reporter
The goal of this project was to improve the metrics reporting of SACCT via a CLI tool to make managing a customers cluster easier.
What was done
- Creation of a command line tool into SACCT that is able to convert line by line metrics into general metrics of cluster usage
- Able to filter to specific time periods, users, states and overall metrics to see how the cluster changed over time
- Export metrics to CSV tables for later processing
What was learned
- How Ruby command line tools can interface with an active database
- How metrics can be used and displayed as require
SACCT API
The goal of this project was to use the knowledge from the SACCT CLI tool to act as an API to return JSON data on a SACCT cluster to result in a logical tree of the current usage of said cluster.
What was done
- An API that interfaces with SACCT and allows for you to filter out SACCT metrics by user to see their usage
- Allows you to see the time spread (7/30/90 days) of change or allows you to put in a specific amount of days back of usage
- A CLI tool that allows for the API to be called without using Curl on your device.
- Said CLI tool also stores the current API address to make operations easier.
What was learned
- How an API can accept calls to query an active database
- How to construct command line tools from a API call
- How to return a structured JSON dump that contains all the necessary information
- How to visualise and collate single point data into a summary
- How to deploy an API on a cluster
- How to make the user experience worthwhile and make management easier.
