Display remaining time for deployment

System

Hi,

We have a requirement like displaying the remaining time for the deployment, in a graphical representation. Its like showing a progress bar kind of thing which should show the remaining time period for the deployment.

We have the below mentioned strategical implementation for this (Ref: Open Deploy Administration Guide). There are two input params for the calculation.
1. Elapsed column. 2. Average Data Rate column.

Remaining Data to be transfered = Total Size of the attachments - (Elapsed column * Average Data Rate column.)

Remaining time for the deployment = Remaining Data to be transfered / Average Data Rate column

**************************************************************
We have planned to implement this using CGI. But right now, we are not sure how to read the above mentioned data (Elapsed column & Average Data Rate column) in CGI.

Is there a way to read these data? If yes, then please suggest the steps.

If there is any other approach then kindly suggest.

Thanks in advance.
