Ksar

This article is about getting statistics about past system activity like this:

To get this graph,

• collect all system data, in this example for 20 intervals lasting 1 second each, using the data file /tmp/sar.out:

sar -o /tmp/sar.out 1 20

• convert the binary data to a human-readable format. -A stands for "all".

export LC_ALL=C; sar -A -f /tmp/sar.out >/tmp/sar.out.txt

• Download and install kSar
• run kSar using the human-readable data file:

java -jar kSar.jar -input /tmp/sar.out.txt
