Realtime DTrace Analysis
========================
A collection of scripts used for realtime DTrace visualizations and analysis
Stream gnuplot
--------------
`stream-gnuplot.sh` is a script that reads from stdin to generate live gnuplot
graphs. It takes input in the form of:
\n
The DTrace scripts provided will output in this format, so they can be piped into
`stream-gnuplot.sh`.
Examples
--------
### Syscall Latency/Count Visualization
Visualize syscall latency or counts using gnuplot. An example of this can be seen here
