Vmstax
Learning Flex 3, i wanted to test the chart functionnalities. As a case study, i took the problematic of drawing charts from a vmstat log. At the end of your load tests, you have to build the charts. It may take a long time to do that using Word or OpenOffice and it is not one of my favorite task. So, i decided to make an application in Flex : you upload a vmstat log file, the charts are displayed and finally, you can export them as images so you can include them into your reports.
Documentation
The allowed vmstat formats are :
- Vmstat (kernel 2.6)
- Vmstat (kernel 2.4)
- Vmstat (Solaris)
- Vmstat (AIX)
Example how to generate the log file with vmstat :
vmstat -n 5 > vmstat.log
Example how to generate the log file with dstat :
dstat --output dstat.log-d -m -p -g -s -n -N eth0,eth1 -c -C 0,1
