Hello,<br><br>I&#39;m using GSN on a computer science laboratory and I&#39;m trying to understand some of the attributes of the XML description of a VS.<br>Can some body explain to me the meaning of the following attributes ?
<br><br clear="all">&lt;life-cycle pool-size=&quot;X&quot; /&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I have read that X is the number of VS GSN can execute at the same time. So, is-it possible to have several instances of a VS during the run ?<br><br>
&lt;storage history-size=&quot;Y&quot; /&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp; I know that it is possible to execute SQL requests on a time window. If I write history-size=&quot;1m&quot; my request will only be compute on the last 1 minute values ?
<br><br>&lt;source storage-size=&quot;Z&quot;&gt;<br>&nbsp;&nbsp;&nbsp; Here again I would like to know if I can explain a time window. If it is, what is the relation between this time window and the previous one previously explained ?<br>
About this 2 windows, is it possible to define a set of elements instead of time ? (for example the 10 last values)<br><br>Ok, thank you for your help,<br><br>Cheers ;)<br><br><br>-- <br>=============================<br>Olivier PASSALACQUA
