Get System Information of a Remote Machine (Using Java)

Question

As the question\'s title says, I want to get the system information (like OS name, version, etc.) of a remote system using Java. But before anyone answers this question, I j

Answer 1

well as mentioned above, you can try them. By the way after getting connected you can use following codes:(if you wish)

 import java.util.Properties;
  public class GetCompleteSystemInfo {

public static void main(String args[]) {
    //1.Get Java Runtime
    Runtime runtime = Runtime.getRuntime();
    System.out.println("Runtime=" + Runtime.getRuntime());

    //2. Get Number of Processor availaible to JVM
    int numberOfProcessors = runtime.availableProcessors();
    System.out.println(numberOfProcessors + " Processors ");

    //2. Get FreeMemory, Max Memory and Total Memory
    long freeMemory = runtime.freeMemory();
    System.out.println("Bytes=" + freeMemory + " |KB=" + freeMemory / 1024 + " |MB=" + (freeMemory / 1024) / 1024+" Free Memory in JVM");

    long maxMemory = runtime.maxMemory();
    System.out.println(maxMemory + "-Bytes " + maxMemory / 1024 + "-KB  " + (maxMemory / 1024) / 1024 + "-MB " + " Max Memory Availaible in JVM");

    long totalMemory = runtime.totalMemory();
    System.out.println(totalMemory + "-Bytes " + totalMemory / 1024 + "-KB " + (totalMemory / 1024) / 1024 + "-MB " + " Total Memory Availaible in JVM");


    //3. Suggest JVM to Run Garbage Collector
    runtime.gc();

    //4. Suggest JVM to Run Discarded Object Finalization
    runtime.runFinalization();

    //5. Terminate JVM
    //System.out.println("About to halt the current jvm");//not to be run always
    //runtime.halt(1);
    // System.out.println("JVM Terminated");

    //6. Get OS Name
    String strOSName = System.getProperty("os.name");
    if (strOSName != null) {
        if (strOSName.toLowerCase().indexOf("windows") != -1) {
            System.out.println("This is "+strOSName);
        } else {
            System.out.print("Can't Determine");
        }
    }

    //7. Get JVM Spec
    String strJavaVersion = System.getProperty("java.specification.version");
    System.out.println("JVM Spec : " + strJavaVersion);
    //8. Get Class Path
    String strClassPath = System.getProperty("java.class.path");
    System.out.println("Classpath: " + strClassPath);

    //9. Get File Separator
    String strFileSeparator = System.getProperty("file.separator");
    System.out.println("File separator: " + strFileSeparator);

    //10. Get System Properties
    Properties prop = System.getProperties();
    System.out.println("System Properties(detail): " + prop);

    //11. Get System Time
    long lnSystemTime = System.currentTimeMillis();
    System.out.println("Milliseconds since midnight, January 1, 1970 UTC : " + lnSystemTime + "\nSecond=" + lnSystemTime / 1000 + "\nMinutes=" + (lnSystemTime / 1000) / 60 + ""
            + "\nHours=" + ((lnSystemTime / 1000) / 60) / 60 + "\nDays=" +   (((lnSystemTime / 1000) / 60) / 60) / 24 + "\nYears=" + ((((lnSystemTime / 1000) / 60) /  60) / 24) / 365);
      }
   }
