Description

This ticket adds a simple command line tool for posting Solr logs to a solr index. The tool works with the out of the box Solr log format. Still a work in progress but currently indexes:

• queries
• updates
• commits
• new searchers
• errors - including stack traces

Attached are some sample visualizations using Solr Streaming Expressions and Math Expressions after the data has been loaded. The visualizations show: time series, scatter plots, histograms and quantile plots, but really this is just scratching the surface of the visualizations that can be done with the Solr logs.
