This table explains how to configure disk free space monitoring in VMware Tanzu GemFire.
To modify disk-usage-warning-percentage
and disk-usage-critical-percentage
thresholds, specify the parameters when executing the gfsh create disk-store
command.
gfsh>create disk-store --name=serverOverflow --dir=c:\overflow_data#20480 \
--compaction-threshold=40 --auto-compact=false --allow-force-compaction=true \
--max-oplog-size=512 --queue-size=10000 --time-interval=15 --write-buffer-size=65536 \
--disk-usage-warning-percentage=80 --disk-usage-critical-percentage=98
By default, disk usage above 80% triggers a warning message. Disk usage above 99% generates an error and shuts down the member cache that accesses that disk store. To deactivate disk store monitoring, set the parameters to 0.
To view the current threshold values set for an existing disk store, use the gfsh describe
disk-store command:
gfsh>describe disk-store --member=server1 --name=DiskStore1
You can also use the following DiskStoreMXBean
method APIs to configure and obtain these thresholds programmatically.
getDiskUsageCriticalPercentage
getDiskUsageWarningPercentage
setDiskUsageCriticalPercentage
setDiskUsageWarningPercentage
You can obtain statistics on disk space usage and the performance of disk space monitoring by accessing the following statistics:
diskSpace
maximumSpace
volumeSize
volumeFreeSpace
volumeFreeSpaceChecks
