Event Logging from ASP.NET

[Andrew Robinson]

In the past, I remember all kinds of security related issues when trying to
write to the event log but don't remember the specifics. Was there an issue
with creating a new source?

Can you write if you are using the ASP.NET account or Network Services
account? Did this change with .NET v2.0 and/or Win 2003 SP1?
thanks,

Yes. My understanding is that you can write to a log that's been
created, but you can't create a new log.

We have a little Windows.Forms app that creates a log with a given name.
ASP.NET and Web service applications can then write to that log.
Whether or not this is the best solution, I have no idea, but it works
for us.

The "issue" is still there. You can not create new source. But since you do
it only once simply have a desktop program that does it and run it under
Admin account.

Then your ASP.NET will be able to write into event log.

Ok, if I can't create a new Source and I really don't want to require a user
to first run some type of desktop app, any suggestions on an existing source
that is likely to exist that I can use?

Not sure what type of solution you looking for.
New "source" is a simple entry in a registry.
You can
a) created manually
b) create using program that runs under Admin rights.
You choose.

Another option would be not to log into event log and intead send an email
with error info.
That is how all my online application work.

So usually i am there fixing bugs before user called me.

The Application Event Log is a good candidate.

I am afraid you a bit misleading the guy. "Applicatio n" Event Log is a name
of the log and not a source.
There are 2 components when writing into even log.

Source and Log Name.

Log Name identifies which event log. "Applicatio n", "System"... . You can
create your own name and it will be shown in the Even Viewer as a root node.

Then there is a Source of the event. Source basically points to which
application has created that entry in event log. You can see Source as a
column in the event viewer.

So folowing code
if (!EventLog.Sour ceExists("TEST" ))

EventLog.Create EventSource("TE ST", "Applicatio n");

EventLog.WriteE ntry("TEST", msg, EventLogEntryTy pe.Error);

will create even source TEST connected to event log "Applicatio n" and then
write there with source "TEST"

You need to have admin rights to create both new Log (usually "Applicatio n"
is used so no need to create it).
and new source.

George.
