Configuring Disk Free Space Monitoring
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 disable 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:
