We have a server running Tru64 Unix, which is our main production server for a single application our organisation uses. The software vendor has complete control of the hardware and software (we still administer the software, but have no root access).
however the vendor has allowed us to run vmstat, which will produce output every 15 seconds for 10 intervals then exit.
I was going to setup an automated process that would run vmstat, logging the output. I thought this would be quite useful information, especially considering we have had performance issues lately.
Mangement have told me that I cannot do this as vmstat chews up a lot of resources and will slow the system down if it is constantly running.
Can anyone tell me if this is actually true?
