When scanning the log is not sufficient, you can monitor your applications programmatically. For example, you can send messages of a certain type in an email.
You can write methods that are passed a class representing every error or warning message that is printed to the log. This may help you monitor and audit a MobiLink server.
The following code installs a LogListener for all warning messages, and writes the information to a file.
class TestLogListener implements LogListener {
FileOutputStream _out_file;
public TestLogListener( FileOutputStream out_file ) {
_out_file = out_file;
}
public void messageLogged( ServerContext sc,
LogMessage msg ) {
String type;
String user;
try {
if(msg.getType() == LogMessage.ERROR) {
type = "ERROR";
} else if(msg.getType() == LogMessage.WARNING) {
type = "WARNING";
} else {
type = "UNKNOWN!!!";
}
user = msg.getUser();
if( user == null ) {
user = "NULL";
}
_out_file.write(
("Caught msg type=" + type +
" user=" + user +
" text=" +msg.getText() +
"\n").getBytes() );
_out_file.flush();
} catch( Exception e ) {
// Print some error output to the MobiLink log.
e.printStackTrace();
}
}
}
The following code registers TestLogListener to receive warning messages. Call this code from anywhere that has access to the ServerContext such as a class constructor or synchronization script.
// ServerContext serv_context;
serv_context.addWarningListener(
new MyLogListener( ll_out_file ));
