Comando para obter registos de um eventId:


LogParser "SELECT * Strings AS Parameters FROM Application WHERE EventID=20503 

LogParser - More Commands


Examples
Keep in mind that most of the examples that I give here are all-in-one command line queries (even though many wrap to multiple lines when displayed here). However, queries can also be run as
logparser file:XXXXX.sql
where XXXXX is the name of a file containing a logparser-friendly sql query. There are a couple examples of this in the following list.
The examples given here have been obtained from a variety of sources, including the documentation that ships with the tool, blogs and online documentation, and my own experience. Unfortunately, I don’t have a record of the origin of each individual example, as I’ve compiled these piecemeal over the last two or three years.
I hope you’ll find something useful here and gain an appreciation for just how robust this tool is.
1) All pages hits by a given IP address
logparser "select cs-uri-stem, count(cs-uri-stem) as requestcount from [LogFileName] where c-ip = ’000.00.00.000′ group by cs-uri-stem order by count(cs-uri-stem) desc"

21) Search the Event Log for W3SVC (IIS) log entries and color-coordinate as to Error, Warning, Information. This example writes the output of the query to an HTML file that is generated using a template file.
logparser "SELECT TimeGenerated,EventTypeName,Strings,Message,CASE EventTypeName WHEN ‘Error event’ THEN ‘RED’ WHEN ‘Warning event’ THEN ‘YELLOW’ WHEN ‘Information event’ THEN ‘WHITE’ ELSE ‘BLUE’ END As Color INTO file.html FROM System WHERE SourceName = ‘W3SVC’" -tpl:IISEventLogEntries.tpl

23) Top 10 images by size sent. Note that this example also shows how to query multiple log files at once.
logparser "Select Top 10 StrCat(Extract_Path(TO_Lowercase(cs-uri-stem)),’/') AS RequestedPath, Extract_filename(To_Lowercase(cs-uri-stem)) As RequestedFile, Count(*) AS Hits, Max(time-taken) As MaxTime, Avg(time-taken) As AvgTime, Max(sc-bytes) As BytesSent INTO TOP10ImagesBySize.txt FROM logs\iis\ex*.log WHERE (Extract_Extension(To_Lowercase(cs-uri-stem)) IN (‘gif’;'jpg’;'png’)) AND (sc-status = 200) GROUP BY To_Lowercase(cs-uri-stem) ORDER BY BytesSent, Hits, MaxTime DESC"
24) Browser types (two different approaches)

25) Unique visitors per day. This requires two queries. The first query selects from the IIS logs into a CSV file, and the second selects from that CSV file.
logparser "SELECT DISTINCT cs-username, date INTO tempUniqueVisitorsPerDay.csv FROM logs\iis\ex*.log WHERE cs-username <> NULL Group By Date, cs-username"
logparser "SELECT date, count(cs-username) as UniqueVisitors into test.txt FROM tempUniqueVisitorsPerDay.csv GROUP BY date"
26) Top 10 largest ASPX pages.
logparser "Select Top 10 StrCat(Extract_Path(TO_Lowercase(cs-uri-stem)),’/') AS RequestedPath, Extract_filename(To_Lowercase(cs-uri-stem)) As RequestedFile, Count(*) AS Hits, Max(time-taken) As MaxTime, Avg(time-taken) As AvgTime, Max(sc-bytes) As BytesSent INTO top10pagesbysize.txt FROM logs\iis\ex*.log WHERE (Extract_Extension(To_Lowercase(cs-uri-stem)) IN (‘aspx’)) AND (sc-status = 200) GROUP BY To_Lowercase(cs-uri-stem) ORDER BY BytesSent, Hits, MaxTime DESC"
27) Top 10 slowest ASPX pages

28) Top 10 slowest ASPX pages on a specific day
logparser "SELECT TOP 10 cs-uri-stem, max(time-taken) as MaxTime, avg(time-taken) as AvgTime INTO toptimetaken.txt FROM logs\iis\ex*.log WHERE extract_extension(to_lowercase(cs-uri-stem)) = ‘aspx’ AND TO_STRING(To_timestamp(date, time), ‘MMdd’)=’1003′ GROUP BY cs-uri-stem ORDER BY MaxTime DESC"
29) Daily bandwidth
logparser "Select To_String(To_timestamp(date, time), ‘MM-dd’) As Day, Div(Sum(cs-bytes),1024) As Incoming(K), Div(Sum(sc-bytes),1024) As Outgoing(K) Into BandwidthByDay.gif From logs\iis\ex*.log Group By Day"
30) Bandwidth by hour
logparser "SELECT QUANTIZE(TO_TIMESTAMP(date, time), 3600) AS Hour, SUM(sc-bytes) AS TotalBytesSent INTO BytesSentPerHour.gif FROM logs\iis\ex*.log GROUP BY Hour ORDER BY Hour"

logparser "Select Top 20 cs-username AS UserName, AVG(time-taken) AS AvgTime, Count(*) AS Hits INTO AvgTimePerUser.txt FROM logs\iis\ex*.log WHERE cs-username IS NOT NULL GROUP BY cs-username ORDER BY AvgTime DESC"
32) Ave page load time for a specific user
logparser "Select cs-username AS UserName, AVG(time-taken) AS AvgTime, Count(*) AS Hits INTO AvgTimeOnSpecificUser.txt FROM logs\iis\ex*.log WHERE cs-username = ‘CONTOSO\User1234’ GROUP BY cs-username"
33) Error trends. This query is quite long, and is easier expressed in a text file than on the command line. So, Log Parser reads and executes the query contained in the specified text file.
logparser file:errortrend.sql
Where errortrend.sql contains the following:
SELECT
TO_STRING(To_timestamp(date, time), ‘MMdd’) AS Day,

How Transactional Replication Works

Transactional replication is implemented by the SQL Server Snapshot Agent, Log Reader Agent, and Distribution Agent. The Snapshot Agent prepares snapshot files containing schema and data of published tables and database objects, stores the files in the snapshot folder, and records synchronization jobs in the distribution database on the Distributor.
The Log Reader Agent monitors the transaction log of each database configured for transactional replication and copies the transactions marked for replication from the transaction log into the distribution database, which acts as a reliable store-and-forward queue. The Distribution Agent copies the initial snapshot files from the snapshot folder and the transactions held in the distribution database tables to Subscribers.
Incremental changes made at the Publisher flow to Subscribers according to the schedule of the Distribution Agent, which can run continuously for minimal latency, or at scheduled intervals. Because changes to the data must be made at the Publisher (when transactional replication is used without immediate updating or queued updating options), update conflicts are avoided. Ultimately, all Subscribers will achieve the same values as the Publisher. If immediate updating or queued updating options are used with transactional replication, updates can be made at the Subscriber, and with queued updating, conflicts might occur. For more information, see How Updatable Subscriptions Work.
