Search logs are kept for the search cluster as well as for each node in the search cluster. The cluster logs are stored in the \cluster\log folder, for example, C:\bea\alui\cluster\log\cluster.log. The cluster logs include cluster-wide state changes (such as cluster initialization, node failures, and node recoveries), errors, and warnings.

The node logs are stored in the node’s logs folder, for example, C:\bea\alui\ptsearchserver\6.5\node1\logs. There are two kinds of node logs: event logs and trace logs. Event logs capture major node-local state changes, errors, warnings, and events. Trace logs capture more detailed tracing and debugging information.

A new cluster log is created with each new checkpoint. The log that stores all activity since the last checkpoint is called cluster.log. When a new checkpoint is created, the cluster.log file is saved with the name checkpoint.log, for example, 0_1_5116.log.
