process vmstat log files using script/application

Question

I want to monitor the performance metrics of solaris 10 server like average memory and cpu usage. At the moment i have set up a script to run vmstat once every x seconds and log to a file.

 vmstat x >> perf.log  

  kthr      memory            page            disk          faults      cpu

Now I need to analyse this log file and compute the average memory and cpu usage. Is there any tool available for this, or even a better way to do this.

Edit: Found a tool https://github.com/jsargiot/vmstatly

for java you can use `visualVM` [Link](http://visualvm.java.net) — Jubin Patel, Dec 21 '12 at 11:32
Thank you, I use jvisualVM, but it has the same problem. I want to find out the average CPU & memory usage, it doesn't show the average, it gives a nice graph but that's not what I want. — Radan, Dec 21 '12 at 11:52
