If you do not want to install VRAdvisor and VxVM is installed on your system, use the vxstat command to collect data.
To collect data using vxstat
# export LC_ALL=C
# vxstat -g dgname -i interval -c count volumes > filename
where:
interval is the data collection interval in seconds.
count is the number of samples to collect.
volumes is a list of volume names separated by spaces.
For example, use the following command to collect a sample of data every 120 seconds and to collect 5040 samples. The volumes are the data volumes hr_dv01 and hr_dv02 in the disk group hrdg. The results are collected in the file vra_in.
# vxstat -g hrdg -i 120 -c 5040 hr_dv01 hr_dv02 > vra_in
After the data collection completes, the file filename (for example, vra_in) contains the sample of data in the vxstat format, which can be used for analysis by VRAdvisor. You can proceed to analyze the collected data using VRAdvisor.
