First Release

For details, kindly refer to: http://arcolife.github.io/blog/2016/06/06/sarjitsu-a-project-on-visualizing-your-systems-activity/

Offerings

Sarjitsu offers visualizations for Operating System stats for:

• Paging
• Disks / block device activity*
• Kernel Tables [Inode Files, others]
• Task creation and system switching
• Hugepages
• I/O and Transfer rate statistics
• Swap usage / statistics
• Memory utilization / page usage by system
• CPU utilization*
• Queue: Load Averages
• Network statistics*

Note (): Features marked with asterix () are currently not directly
consumable through sarjitsu v1.0, due to Grafana 3.0.0's inability
to deal with nested documents inside elasticsearch (which is what
sarjitsu uses for data ingestion). However, there's a PR #4694 that
has been submitted to deal with the same (but hasn't been merged yet).
