Hi,

Is the way I can run a clover graph as a result of External Agent. The requirement of my project is,

Data comes as a mail each day, now the execution has to begin as a result of the mail.

Regards,  
Rama.

Hello Rama,

yes, there is the way.  
There are basically two possibilities.

1] Solution on the mail server  
You can execute script for incoming message. The script can execute Clover.  
Here is some thread about similar topic on Linux Questions:  
[http://www.linuxquestions.org/questions … ved-55835/](http://www.linuxquestions.org/questions/linux-general-1/run-script-when-email-is-received-55835/)

2] solution on the client  
Make a script which periodically looks up for new messages on the server and when new message comes, it executes Clover graph.  
Or you can use Clover graph instead of the script  
\* Data Generator component generates some dummy data  
\* Speed Limiter component defines periodicity  
\* System Execute component executes script which looks up for new messages on the server  
… or you can use Java execute and implement java code which reads the messages from the server  
\* Run Graph executes the graph as a response for each message

Regards,  
Martin
