 With [ECII-246](https://jira.eso.org/browse/ECII-246), it is possible to change the log levels of the MAL loggers at run-time via a method call:
 
 ```plaintext
+#include <mal/util/MalLoggingUtil.hpp>
 ::elt::mal::util::logging::setLogLevelForLoggers( ... )
+
+    // set all mal loggers to INFO...
+    std::vector<elt::mal::util::logging::LoggerInfo> loggers = elt::mal::util::logging::getLoggers();
+    std::vector<elt::mal::util::logging::LoggerInfo> info;
+    for (auto const& logger : loggers) {
+      info.push_back(elt::mal::util::logging::LoggerInfo(logger.loggerName, ::log4cplus::INFO_LOG_LEVEL));
+    }
+    elt::mal::util::logging::setLogLevelForLoggers(info);  
+
+    // print all mal loggers and log level
+    loggers = elt::mal::util::logging::getLoggers();
+    std::cout << "Loggers:\n";
+    for (auto const& logger : loggers) {
+      std::cout << "\t" << logger.loggerName << ": " << logger.logLevel << std::endl;
+    }
+
 ```
 
 The allowed logger names are listed below.
