1147.0. "writing captured data to disk (probewatch/ultrix)" by GIDDAY::STRAUSS (talking through my binoculars) Wed Jun 22 1994 23:38

    If this is the wrong place to ask, I hope someone can redirect me ...
    
    A customer using Probewatch for Ultrix V1.0 wants to understand how
    captured frames are written to disk.  Presumably captured frames are
    stored in a buffer, and the buffer is periodically written to disk.
    
    Is this how it's done?  If so, how big is the buffer, and what triggers
    the write?  (buffer full, or something else?)
    
    Thanks in advance for any help.

    ps - I don't know why the customer wants to know this ...

	The packets are captured according to the filters set up and stored in dynamic RAM on the probe. It is kept there, either wrapping when the buffer is full, or stopping when full, as directed by PROBEwatch. I believe it can store 1 Megabyte. The data is uploaded to disk, when directed by the PROBEwatch user, through a click on UPLOAD. If power is lost to the probe prior to uploading to disk, the captured data is gone forever.
