Logging

Configure log files at the cluster server level and project level. A cluster node may contain multiple projects, each with their own project log.

In Event Stream Processor, projects run on local and remote clusters. Cluster-level logging is available for remote clusters only. Therefore, projects that run on the local cluster do not generate a cluster log file. They do, however, generate project-level logs.

Note: Projects started in Studio run on the local cluster unless the project has an explicit connection to a remote cluster defined. For information on running projects on the local cluster, see the Studio Users Guide.

Event Stream Processor stores logs in flat files. Although ESP does not provide built-in tools for analyzing these files, you can use third-party log file analyzer tools to perform analysis on the logs.

Cluster Node Log Configuration File
The configuration file for node logging is cluster.log.properties, which is a log4j property file.
Project Logging
Configure project logs to capture errors in running projects. You can configure logs for single or multiple projects in a cluster.
