With WMI running on a computer, and sufficient administrative credentials owned by the user running WMIC, local or remote monitoring of a computer is available at the command line. In noninteractive mode, multiple commands can be contained in a batch file that is run either manually or on an automated schedule. These WMIC commands can be output to a CSV file, text file, or HTML page to be viewed and analyzed. Following are examples of common monitoring scenarios and output that illustrate the use of WMIC for monitoring.

PRODUCT This command will output to the console the results of a query for all installed software on the local computer.

/OUTPUT:c:\applog.htm NTEVENT WHERE "eventtype<3 AND logfile='Application'" GET Logfile, SourceName, Eventtype, Message, TimeGenerated/FORMAT:htable:"sortby=EventType This command will output to an HTML file (C:\applog.htm) any events with types 0, 1, or 2 from the Application Log of the local computer. The list will be formatted in an HTML table (using the XML stylesheet htable.xsl) and sorted by Event Type.

/OUTPUT:c:\applog.csv/NODE:@"c:\serverlist.txt NTEVENT WHERE eventtype<3 AND logfile='Application'" GET Logfile, SourceName, Eventtype, Message, TimeGenerated/FORMAT:csv:"sortby=EventType This command will output to a CSV file (c:\applog.csv) any events with types 0, 1, or 2 from the Application Logs of the computers in the file serverlist.txt.

In this practice, you will extract data from the Event Viewer and publish it to a Web page. 1. Logged on as Administrator on Server01, open a command window, type wmic, and press ENTER. This enters WMIC in interactive mode. 2. At the WMIC prompt, type the following command to access the Security Log data from Lesson 1, Exercise 3: NTEVENT WHERE "EVENTTYPE=5 AND LOGFILE='SECURITY'" GET LOGFILE, SOURCENAME, EVENTTYPE, MESSAGE, TIMEGENERATED This outputs the Failure Audit entries to the console. 3. At the WMIC prompt, type the following command to output the same information to a Web page called C:\seclog.htm. /OUTPUT:C:\seclog.htm NTEVENT WHERE "EVENTTYPE=5 AND LOGFILE='SECURITY'" GET LOGFILE, SOURCENAME, EVENTTYPE, MESSAGE, TIMEGENERATED/FORMAT:htable 4. Double-click the file C:\Seclog.htm to open the file in Microsoft Internet Explorer.
