Importing Message Tracking Logs into a Database without using WMI

A while ago I wrote a little Message Tracking Log application that I posted here on OutlookExchange. Somebody asked me today for a way to import a lot of tracking logs that they have archived in a directory where using WMI wasn't really going to be applicable. Fortunately this isn't that hard a thing to do, the message tracking logs are in essence a tab delimited text file with a few twists. The first twist is you really want to ignore the first 5 lines and the second is there is a double Line Feed at the end of each line. But because this is consistent it isn't hard to script around this.

So to do the hardwork of sorting out the tab delimited data in VBS you can use the Split command which will split the contents of each line into separate array elements where the delimiter separates the column. You still need to apply the same functions such as converting GMT time to local time and the time and data retrievals are a little different as they are stored in a little bit of a weird format.

The last hurdle was to front the code with something that would go though every file in a directory which can be done using the filesystem object.

The result was the following script that imports tracking log data into the database out of the article I mentioned.



set shell = createobject("wscript.shell")
strValueName = "HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\ActiveTimeBias"
minTimeOffset = shell.regread(strValueName)
toffset = datediff("h",DateAdd("n", minTimeOffset, now()),now())
Set fso = CreateObject("Scripting.FileSystemObject")
Set Cnxn1 = CreateObject("ADODB.Connection")
strCnxn1 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:\Trackinglog.mdb;"
Cnxn1.Open strCnxn1
set f = fso.getfolder("c:\logdir")
Set fc = f.Files
For Each file1 in fc
wscript.echo file1.path
importtodb(file1.path)
next
wscript.echo "Done"

function importtodb(fname)
set wfile = fso.opentextfile(fname,1,true)
for i = 1 to 5
wfile.skipline
next
nline = wfile.readline
do until wfile.AtEndOfStream
if instr(nline," ") then
inplinearray = Split(nline, " ", -1, 1)
if inplinearray(8) = "1020" or inplinearray(8) = "1028" then
ClientIP = inplinearray(2)
if (isnull(ClientIP)) then ClientIP = "N/A"
Entrytype = inplinearray(8)
if (isnull(Entrytype)) then Entrytype = "N/A"
Subject = inplinearray(18)
if (isnull(Subject)) then Subject = "N/A"
RecipientAddress1 = inplinearray(7)
if (isnull(RecipientAddress1)) then RecipientAddress1 = "N/A"
RecipientCount = inplinearray(13)
if (isnull(RecipientCount)) then RecipientCount = "N/A"
SenderAddress = inplinearray(19)
if (isnull(SenderAddress)) then SenderAddress = "N/A"
size1 = inplinearray(12)
if (isnull(size1)) then size1 = "N/A"
datearray = split(inplinearray(0),"-",-1,1)
timearray = split(inplinearray(1),":",-1,1)
odate = dateserial(datearray(0),datearray(1),datearray(2))
otime = timeserial(timearray(0),timearray(1),0)
odate = dateadd("h",toffset,cdate(odate & " " & otime))
wtowrite = "('" & condate(odate) & "','" & formatdatetime(odate,4) & "','" & ClientIP & "','" & EntryType & "','" & RecipientCount & "','" & SenderAddress & "','" & RecipientAddress1 & "','" & left(replace(subject,"'"," "),254) & "','" & size1 & "')"
sqlstate1 = "INSERT INTO TrackingLogRaw ( [Date], [Time], [client-ip], [Event-ID], NoRecipients, [Sender-Address], [Recipient-Address], [Message-Subject], [total-bytes] ) values " & wtowrite
Cnxn1.Execute(sqlstate1)
end if
end if
nline = wfile.readline
loop
wfile.close
set wfile = nothing
end function


function condate(date2con)
dtcon = date2con
if month(dtcon) < 10 then
if day(dtcon) < 10 then
qdat = year(dtcon) & "0" & month(dtcon) & "0" & day(dtcon)
else
qdat = year(dtcon) & "0" & month(dtcon) & day(dtcon)
end if
else
if day(dtcon) < 10 then
qdat = year(dtcon) & month(dtcon) & "0" & day(dtcon)
else
qdat = year(dtcon) & month(dtcon) & day(dtcon)
