<div class="block">Statistics for a replicated environment.
<p>
The statistics are logically grouped into four categories. Viewing the
statistics through <a href="../../../../com/sleepycat/je/rep/ReplicatedEnvironmentStats.html#toString--"><code>toString()</code></a> displays
the values in these categories, as does viewing the stats through the <a href="../../../../../jconsole/JConsole-plugin.html">RepJEMonitor
mbean</a>. Viewing the stats with <a href="../../../../com/sleepycat/je/rep/ReplicatedEnvironmentStats.html#toStringVerbose--"><code>toStringVerbose()</code></a> will provide more detailed
descriptions of the stats and stat categories.
<p>
The current categories are:
<ul>
<li><b>FeederManager</b>: A feed is the <a
href="../../../../../ReplicationGuide/introduction.html#replicationstreams">replication
stream</a> between a master and replica. The current number of feeders
gives a sense of the connectivity of the replication group.
</li>
<li><b>BinaryProtocol</b>: These statistics center on the network traffic
engendered by the replication stream, and provide a sense of the network
bandwidth seen by the replication group.
</li>
<li><b>Replay</b>: The act of receiving and applying the replication stream
at the Replica node is called Replay. These stats give a sense of how much
load the replica node is experiencing when processing the traffic from the
replication group.
</li>
<li><b>ConsistencyTracker</b>: The tracker is invoked when consistency
policies are used at a replica node. This provides a measure of delays
experienced by read requests at a replica, in order to conform with the
consistency specified by the application.
</li>
