To display Storage Mapping and I/O statistics information at repeated intervals
◆
Use the vxstorage_stats command with the -i interval and -c count
options to display storage mapping and I/O statistics information at repeated
intervals. The -i interval option specifies the interval frequency for
displaying updated I/O statistics and the -c count option specifies the number
of times to display statistics.
$ /opt/VRTSdbed/bin/vxstorage_stats -m [-s] \
[-i interval -c count ] -f file_name
$ /opt/VRTSdbed/bin/vxstorage_stats [-m] -s \
[-i interval -c count ] -f file_name
For example, to display statistics twice with a time interval of two seconds:
$ /opt/VRTSdbed/bin/vxstorage_stats -s -i2 -c2 \
-f /snap_data11r1/FLAS11r1/system01.dbf
Output similar to the following is displayed:
