<p class="MsoNormal">This is on purpose.<br>
<br>
When Vitrage is started, it first runs a "consistency" round where it gets all the resources from its datasources and inserts them into the entity graph. Once this initial phase is over, the evaluator is run over all the entity graph to check for meaningful
patterns based on it's templates.<br>
<br>
The reason for this process is to avoid too much churn during the initial phase when Vitrage comes up. With so many changes done to the entity graph, it's best to wait for the initial collection phase to finish and then to do the analysis.<br>
