Common command line tools are often the best for analyzing and understanding HPC clusters and issues. People have often asked me for tools and web pages to figure out how to understand and figure out issues in our cluster, or asked if we could use some tool like Hadoop, Spark, or some Azure/GCP/AWS tool to do it faster. I've said that if they want to spend the effort to use those tools, it could be valuable; but if it takes me 10min to use those tools and <1min using command line tools, I'll always fall back to the command line.

That's not to say that fancy tools don't have their use; but people often forget how much you can do with a few simple commands if you understand a pipeline and how the commands work.
