<h1>Monitor Object Lifecycle</h1>
<p>You can monitor the object lifecycle statistics of db4o to find out more about the runtime behavior of your application.</p>
<h2>Configure the Object Lifecycle Monitoring Support</h2>
<p>In order to monitor the object lifecycle statistics, you need to add the monitoring support to the configuration.</p>

If there's a lot of time spend with activating objects, you may want to reduce the amount of activated objects. One of the best way to activate only the minimum set of objects is to use <a href="../../basics/activation_concept/transparent_activation_framework.htm">transparent activation</a>.</p>
