You may talk about Graphite, but graffit is crap: > http://grisha.org/blog/2015/05/04/recording-time-series/ > A few years ago, Alfred Perlstein wrote a tool called Eagleeye: https://github.com/splbio/eagleeye This tool did a few things: -> ran various tools like netstat, vmstat, gstat -> parsed the output of the various tools -> produce web based reports for doing correlation of the data This was very useful for performance analysis. Since the code for Eagleeye is on GitHub, maybe some FreeBSD coders who have interest can update Eagleeye to produce output from the system with libxo. Having more tools use libxo will definitely make it easier to write tools like Eagleeye. -- Craig -- Craig
