Re: Event log counts...

Hi to everyone.

My first idea would be to create a Win2K Service with WMI support. You could
then create a WMI event handler and attach it to the EventLog WMI interface.
Thus, each time a new event is generated you can extract it´s data and send
it to your syslog in whatever format you want.
I don´t know how much CPU-consuming (and network) would be this solution but
it´s a good approach and you don´t have to take care on how big your events
logs are.
Another solution would be avoiding the WMI event handler and instead create
a timer inside your service who would check your Event Logs. If you make
some tests I´m sure you would find a way to reach a performant service.

Hope that helped.

Subject: Event log counts...


I am currently working on implementing a windows syslog solution in which
Win2k servers will dump their application/system/security event logs to a
(likely Kiwi) syslog server in our environment. One of the questions that
needs to get answered in order to implement such a solution is "How many
total event log entries are we generating per minute/hour/day/week/month
across all 200 of our servers?" I'm currently at a loss as to how to
this question, and so I'm turning to the list for ideas. At first, I was
thinking about just picking a small representative sample of our servers,
and counting the number of events generated in a set period of time.
However, I've had a very hard time picking a small representative sample
our overall server farm, and from my (albeit somewhat limited) research
this avenue, there doesn't appear to be one. Is there a way that I could
query this kind of information somewhere in Windows? In the AD? NetIQ App
Manager? Do you guys know of any sort of utility that I could load that
would help me determine event counts? Should I write my own? Could I find
this information by querying WMI in a small VB app or something?

You ideas and suggestions are greatly appreciated.
