HP-UX Reference (11i v2 07/12) - 1M System Administration Commands N-Z (vol 4)

sar(1M) sar(1M)

blocks in memory (blkcnt) and the number of MemFS blocks in swap (swpcnt). The number of

MemFS blocks is expressed in terms of 4 KB only.

Note that the -z option does not record MemFS data into a ﬁle. However, if the

-z and -o

options are used together, then the data for all the options except the MemFS option is

recorded into a ﬁle. You can then query this data.

It is also not possible to use the

-z option with the -f option. Using the -A option and the

-f option together will not display the MemFS data. However, using the

-A option with t and

n will display the MemFS data.

EXAMPLES

Watch CPU activity evolve for 5 seconds:

sar 1 5

Watch CPU activity evolve for 10 minutes and save data:

sar -o temp 60 10

If the SAR-MEMFS product is installed, watch MemFS activity evolve for 10 minutes and save data; all

data other than MemFS data is stored in ﬁle temp:

sar -z -o temp 60 10

Review disk and tape activity from that period later:

sar -d -f temp

Review CPU utilization on a multiprocessor system later:

sar -u -M -f temp

WARNINGS

Users of sar must not rely on the exact ﬁeld widths and spacing of its output, as these will vary depending

on the system, the release of HP-UX, and the data to be displayed.

The output of sar is unpredictable if a corrupted or wrong data ﬁle is given as argument with the

-f

option.

The behavior of the sa1 and sa2 scripts and the sadc command remain unaltered with the SAR-

MEMFS

product; these scripts and command do not record data reported by the -z option.
