18.5.6 Event Reports Generated in NDB Cluster

In this section, we discuss the types of event logs provided by NDB Cluster, and the types of events that are logged.

NDB Cluster provides two types of event log:

Both types of event logs can be set to log different subsets of events.

Each reportable event can be distinguished according to three different criteria:

Both the cluster log and the node log can be filtered on these properties.

The format used in the cluster log is as shown here:
