GemFire output files are optional and can
become quite large. Work with your system administrator to determine where to place them to
avoid interfering with other system activities.
GemFire includes several types of optional output files as described below.
- Log Files. Comprehensive
logging messages to help you confirm system configuration and to debug
problems in configuration and code. Configure log file behavior in the
gemfire.properties file. See Logging.
- Statistics Archive Files.
Standard statistics for caching and distribution activities, which you can
archive on disk. Configure statistics collection and archival in the
archive-file-size-limit. See gemfire.properties and gfsecurity.properties (GemFire Properties).
- Disk Store Files. Hold
persistent and overflow data from the cache. You can configure regions to
persist data to disk for backup purposes or overflow to disk to control
memory use. The subscription queues that servers use to send events to
clients can be overflowed to disk. Gateway sender queues overflow to disk
automatically and can be persisted for high availability. Configure these
through the cache.xml. See Disk Storage.
