About Cluster Events

Cluster events report topology changes, performance issues, and errors in operations. These events are logged by both Terracotta server (L2) and client (L1), and can also be viewed in the TMC (see the Terracotta Management Console User's Guide).

By default, the L2 stores a maximum of 100 events in memory, and this is the number pulled by the TMC. To edit that number, use the Terracotta property l2.operator.events.store. To set the property in the Terracotta configuration file, use:

<tc-properties>
  ...
  <property name="l2.operator.events.store" value="500" />
</tc-properties>
