Re: Calculating events per sec

For what it's worth, I've calculate that Windows 2000/2003 events take up an
average of just under 1.5Kb (if you include all fields and the message text
portion). If you're just collecting the field values, they average about 500
bytes

For example, the message text for a 680 event appears as:
  Logon attempt by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0  Logon
account:USERID  Source Workstation:WORKSTATION  Error Code:0xC0000072

However, since the actual text and field data are stored separately (the
text is in audite.dll, while the field values are in the secevent.evt file),
you can retrieve just the values:
 MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
USERID
WORKSTATION
0xC0000072

I chose a small event for illustrative purposes, but you can see how there
can be significant space savings depending on how the SIM solution handles
the message. There can also be some space savings if the SIM solution stores
the decimal value for some fields (type, source, category) rather than their
text representations, but this is a lesser issue.
