  • Element Details

    • archiveDiskSpaceLimit

      int archiveDiskSpaceLimit
      Maximum size (in megabytes) of all inactive statistic archive files combined. If this limit is exceeded, inactive archive files are deleted, oldest first, until the total size is within the limit. If set to zero, disk space use is unlimited. Defaults to 0 MB. Use the spring.data.gemfire.stats.archive-disk-space-limit property in application.properties.
      Default:
      0

    • archiveFile

      String archiveFile
      The file to which the running system member writes statistic samples. For example: “StatisticsArchiveFile.gfs”. An empty string disables archiving. Adding .gz suffix to the file name causes it to be compressed. Defaults to unset. Use the spring.data.gemfire.stats.archive-file property in application.properties.
      Default:
      ""

    • archiveFileSizeLimit

      int archiveFileSizeLimit
      The maximum size (in megabytes) of a single statistic archive file. Once this limit is exceeded, a new statistic archive file is created, and the current archive file becomes inactive. If set to zero, file size is unlimited. Defaults to 0 MB. Use the spring.data.gemfire.stats.archive-file-size-limit property in application.properties.
      Default:
      0

    • enableTimeStatistics

      boolean enableTimeStatistics
      Boolean instructing the system to track time-based statistics for the distributed system and caching. Disabled by default for performance reasons and not recommended for production environments. Defaults to false. Use the spring.data.gemfire.stats.enable-time-statistics property in application.properties.
      Default:
      false

    • sampleRate

      long sampleRate
      How often to sample statistics, in milliseconds. Valid values are in the range 100..60000. Defaults to 1000 milliseconds. Use the spring.data.gemfire.stats.sample-rate property in application.properties.
      Default:
      1000L
