sar command to generate only CPU utilization and network statistics in Linux
- by Vijay Shankar Kalyanaraman
I want to be able to generate the system activity report every 30 seconds or every minute and store in a file and use it for diagnostic purposes on my VM. So I give an output file for the sar command and read it using the "-f" option. But I only use the CPU utilization and network utilization part of the report and so rest is all that I don't want to save (waste the space in the disk to store these reports). Also the sar files that are generated are all binary. Is there a way to collect these stats for the CPU and network utilization alone? and so save almost 2/3rds the space on the disk?
