I am running with COMPSs the Increment application shown in the COMPSs Sample Application Manual. I have added the -m flag to enable the monitoring feature:
$ runcompss -m --debug increment.Increment 5 1 2 3
The application runs and finishes properly (no error shown in the std output/error and the runtime.log inside the .COMPSs folder hasn't got any stack trace).
I have also started the COMPSs Monitor service running the following command (I also add its output)
$ /etc/init.d/compss-monitor start

Tomcat started.
However, when I open the monitor webpage I can't select any application execution because the left menu is empty (see image).
Does anyone know how if I need to configure something more to display the COMPSs monitor? Am I missing any other flag to the runcompss command or on the environment?

Check you are away from any magnetic interference The compass sensors are very sensitive to interference. Make sure you are holding your device away from any electric cables/magnetic objects. Also check you don't have a magnet on your case as this can interfere with the sensors.
With iOS 12, Apple has moved the feature into the new Measure app, completely removing its function in the Compass app. For more help getting the most out of your Apple devices, check out our how to guide as well as the following articles: How to add App Store and iTunes gift cards on iPhone and iPad.
Go to Settings > Privacy & Security > Location Services, then turn on Location Services. Tap Compass, then tap While Using the App.
Calibrate Android GPSHold the device right-side up, then move it in a figure-8 motion a few times. The calibration is complete when the beam becomes narrower and points in an accurate direction.
The COMPSs Monitor has an environment variable that points to the folder that will be used to load the executed applications. You can modify its default value by editing the compss-monitor.conf file. For example, you can run:
$ sudo vi /opt/COMPSs/Tools/monitor/apache-tomcat/conf/compss-monitor.conf
IT_MONITOR=/home/yourUSER/.COMPSs/
$ /etc/init.d/compss-monitor restart
By default this variable is pointing to the /root/.COMPSs folder. In the case you described, the monitor is loading the executed applications from this folder instead of /home/yourUSER/.COMPSs/ folder (and that is why you can't see any application's execution).
If you are not willing to modify the default value of this variable remember that you can log in to the monitor (in the wellcome page) using unix user or an absolute path.
For more information please check: COMPSs Application Execution Manual, Section 4.2. COMPSs Monitor.
