LogParser to count number of emails

The task was to count emails sent in and sent out from the organization. LogParser 2.2 presented as an easy tool to parse logs in exchange server for counting the emails. For some reason, COUNT DISTINCT was not working so, I had take a round about.

1. Parse log files and count all MSGID and save the output to as a CSV file.
2. Parse the CSV file created above and count the MSGID
3. Here, I created a graphs as output for few and for others I used the result in excel for further manipulation.

Here are few queries I used:

internal email

SELECT DATE, MSGID, COUNT(MSGID) FROM

WHERE Recipient-Address NOT LIKE '%excludeThis@my.org'

AND Sender-Address NOT LIKE '%excludeThis@my.org%'

AND Sender-Address LIKE '%@my.org%'

For external Emails

LogParser -i:W3C "SELECT Date, MSGID, COUNT(MSGID) FROM \\LogFileLocation\2012*.log WHERE Sender-Address NOT LIKE '%@my.org%' AND Recipient-Address NOT LIKE '%excludeThis@my.org%' AND STRLEN(Sender-Address) > 3 GROUP BY Date, MSGID ORDER BY Date" -o:CSV > X:\ExternalEmail2012.csv

Then used above file to create user usable output file

LogParser -i:CSV "SELECT Year, Month, COUNT(MSGID) FROM X:\ExternalEmail2012.csv GROUP BY Year, Month ORDER BY Month" -o:CSV > H:\MonthlyBreakDown2012.CSV

Few commands for ref:

LogParser /?

LogParser -h -o:chart

LogParser -h -i:CSV

Memory Access Violation

Lesson learnt today!

The old application designed for 16 bit or 32-bit may not run properly in new terminal server setting. Believe me we had a big one!! The application was originally designed in/or 16-bit architecture and we tried to run it in new MS Terminal Server will all bell and whistle but it did not work and gave us memory access violation.

4. Click on Settings under Advance > Performance
5. Select Data Execution Prevention tab
6. Select Turn on DEP for all programs and services except those I select: option
7. Click Add

Padding zeros (0) in front of number or numerical string in T-SQL

To skip story start from the START:
I had to create a Alternate ID from the Employee ID in the following format
ABCD00000
4 characters followed by 5 digits. Employee ID was 4 or 5 digit so would have to pad 0 if 4 digits. I used STR combined with REPLACE function to do this.

START:
Syntax
STR (expression [, length [, decimal] ] )

Return type: varchar

expression: numerical vaue (numerical string would work too)
length: Length of resulting string including - + sign, decimal and digits
decimal: digits after decimal

REPLACE(string, pattern, replacement)

Return type: nvarchar or varchar
string: where you want to replace
pattern: what you want to replace
replacement: string to replace with

Example:

SELECT REPLACE(STR(123.45,10,4), ' ', '0')
SELECT REPLACE(STR('123.45',10,4), ' ', '0')
Result:
00123.4500


SELECT REPLACE(STR(123.45,10,0), ' ', '0')
SELECT REPLACE(STR('123.45',10,0), ' ', '0')
Result:
0000000123


SELECT REPLACE(STR(12345,10,0), ' ', '0')
SELECT REPLACE(STR('12345',10,0), ' ', '0')
Result:
0000012345
