  • 1.  get CPU statistics without root permissions on AIX

    Posted 10/11/22 09:05 AM

    I want to get the per processor statistics for my AIX machines. I can use the 'sar -P ALL 1 1' (Documentation) command but it requires root privileges. Output of the same:



    Is there a command that can give me PER PROCESSOR statistics WITHOUT requiring root privileges?

    Mpstat will show you the individual cores, down to the smt threads

    Try mpstat -a

    Not one command. You may create a new role for running sar and give it to the user. Then the user should log in again to get access to sar.

    As root:

    # create a new role for statistic tools
    $ mkrole authorizations=aix.system.stat aixstat
    # load the role definition into kernel
    $ setkst
    # give the role to the user
    $ chuser roles=aixstat default_roles=aixstat user

    Then login (or re-login) as normal user:

    # check if the role is there
    $ rolelist -e
    ​aixstat
    $ sar -P ALL 1 1

    You must have AIX 6.1 at least with enabled enhanced RBAC (by default it is enabled).

    Best regards
