Hi Mike and Sastry,
Thanks for your information and that makes sense. I am thinking adding dot
graph and pdf output dump, an exercise for me to get familiar with whirl.
Let me know if there are things that need to be specially handled.
Thanks
Yonghong

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
