Reading Data From a Log File

Enabling an application to read data from a log file to a log viewer involves the following tasks:

How to Get an Instance of the Solaris_LogRecord Class and Read Data

  1. Import all the necessary Java classes. The classes listed below are the minimum required.

    import java.rmi.*;
import com.sun.wbem.client.CIMClient;
import com.sun.wbem.cim.CIMInstance;
import com.sun.wbem.cim.CIMValue;
import com.sun.wbem.cim.CIMProperty;
import com.sun.wbem.cim.CIMNameSpace;
import com.sun.wbem.cim.CIMObjectPath;
import com.sun.wbem.cim.CIMClass;
import com.sun.wbem.cim.CIMException;
import com.sun.wbem.solarisprovider.*;
import java.util.*;
import java.util.Enumeration;

  2. Declare the class ReadLog.

    public class ReadLog 
    {
    public static void main(String args[]) throws 
    CIMException 
    {
    if ( args.length != 3) 
    {
    System.out.println("Usage: ReadLog host username 
    password"); 
	    System.exit(1);

  3. Set the CIMClient, CIMObjectPath, and CIMNameSpace values of the ReadLog class.

    } 	
CIMClient cc = null; 
	CIMObjectPath cop = null; 
try { 	    CIMNameSpace cns = new CIMNameSpace(args[0]); 
cc = new CIMClient(cns, args[1], args[2]); 
cop = new CIMObjectPath("Solaris_LogRecord");

  4. Enumerate the instances of Solaris_LogRecord.

    Enumeration e = cc.enumInstances(cop, true);
    for (; e.hasMoreElements(); ) {

  5. Send the property values to an output device.

    System.out.println("---------------------------------");
			CIMObjectPath op = (CIMObjectPath)e.nextElement();
			CIMInstance ci = cc.getInstance(op);
			System.out.println("Record ID : " + 
      (((Long)ci.getProperty("RecordID").getValue().
      
      getValue()).longValue()));
			System.out.println("Log filename : " + 
      ((String)ci.getProperty("FileName").getValue().
      getValue())); 

			int categ = (((Integer)ci.getProperty("category").
      getValue().getValue()).intValue());
			if (categ == 0)
				System.out.println("Category : Application Log");
			else if (categ == 1)
				System.out.println("Category : Security Log");
			else if (categ == 2)
				System.out.println("Category : System Log");

			int severity = (((Integer)ci.getProperty
      ("severity").getValue().getValue()).intValue());
			if (severity == 0)
				System.out.println("Severity : Informational");
			else if (severity == 1)
				System.out.println("Severity : Warning Log!");
			else if (severity == 2)
				System.out.println("Severity : Error!!");

			System.out.println("Log Record written by :" + 
      ((String)ci.getProperty("AppName").getValue().
      getValue()));

			System.out.println("User : " + ((String)ci.
      getProperty("UserName").getValue().getValue()));

			System.out.println("Client Machine : " + ((String)ci.
      getProperty("ClientMachineName").getValue().getValue()));

			System.out.println("Server Machine : " + ((String)ci.
      getProperty("ServerMachineName").getValue().getValue()));

			System.out.println("Summary Message : " + ((String)
      ci.getProperty("SummaryMessage").getValue().getValue()));

			System.out.println("Detailed Message : " + ((String)
      ci.getProperty("DetailedMessage").getValue().getValue()));

			System.out.println("Additional data : " + ((String)
      ci.getProperty("data").getValue().getValue()));

			boolean syslogflag =((Boolean)ci.getProperty("syslogflag").getValue().
      getValue()).booleanValue();
		   if (syslogflag == true) {
			System.out.println("Record was written to syslog as well");
			} else {
			System.out.println("Record was not written to 
      syslog");
			}
			System.out.println("---------------------------------");

  6. Return an error message to the user if an error condition occurs.

    ...
	catch (Exception e) {
	    System.out.println("Exception: "+e);
		e.printStackTrace(); }
...

  7. Close the session when the data has been read from the file.

    // close session.
	if(cc != null) {
	    cc.close();
	}
}
}
