COMPSs Monitor doesn't show any application

Question

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
* Starting COMPSs Monitor
* Checking JAVA Installation...
   Success
* Checking IT_HOME...

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?

Have you checked if the user used to log in the monitor is the same than the one you use to run the application? – Carolanncarole

I have logged in the monitor without specifying any user. However, when I use my user the applications appear. So I guess the default user for the monitor is not right. Do you know how can I change this? – Thirteen

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.
