Using Extended Accounting Functionality

How to Activate Extended Accounting for Processes, Tasks, and Flows

To activate the extended accounting facility for tasks, processes, and flows, use the acctadm(1M) command. The optional final parameter to acctadm indicates whether the command should act on the process, system task, or flow accounting components of the extended accounting facility.

1. Become superuser.

2. Activate extended accounting for processes.

   # acctadm -e extended -f /var/adm/exacct/proc process

3. Activate extended accounting for tasks.

   # acctadm -e extended,mstate -f /var/adm/exacct/task task

4. Activate extended accounting for flows.

   # acctadm -e extended -f /var/adm/exacct/flow flow

How to Activate Extended Accounting With a Startup Script

Activate extended accounting on an ongoing basis by linking the /etc/init.d/acctadm script into /etc/rc2.d.

# ln -s /etc/init.d/acctadm /etc/rc2.d/Snacctadm
# ln -s /etc/init.d/acctadm /etc/rc2.d/Knacctadm

The n variable is replaced by a number.

See "Extended Accounting Configuration" for information on accounting configuration.

How to Display Extended Accounting Status

Type acctadm without arguments to display the current status of the extended accounting facility.

# acctadm
                 Task accounting: active
            Task accounting file: /var/adm/exacct/task
          Tracked task resources: extended
        Untracked task resources: none
              Process accounting: active
         Process accounting file: /var/adm/exacct/proc
       Tracked process resources: extended
     Untracked process resources: host,mstate
                 Flow accounting: active
            Flow accounting file: /var/adm/exacct/flow
          Tracked flow resources: extended
        Untracked flow resources: none

In the previous example, system task accounting is active in extended mode and mstate mode. Process and flow accounting are active in extended mode.

In the context of extended accounting, microstate (mstate) refers to the extended data, associated with microstate process transitions, that is available in the process usage file (see proc(4)). This data provides much more detail about the activities of the process than basic or extended records.

How to View Available Accounting Resources

Available resources can vary from system to system, and from platform to platform. Use the -r option to view the available accounting resources on the system.

# acctadm -r
process:
extended pid,uid,gid,cpu,time,command,tty,projid,taskid,ancpid,wait-status,flag
basic    pid,uid,gid,cpu,time,command,tty,flag

How to Deactivate Process, Task, and Flow Accounting

To deactivate process, task, and flow accounting, turn off each of them individually.

1. Become superuser.

2. Turn off process accounting.

   # acctadm -x process

3. Turn off task accounting.

   # acctadm -x task

4. Turn off flow accounting.

   # acctadm -x flow

5. Verify that task accounting, process accounting, and flow accounting have been turned off.

   # acctadm Task accounting: inactive Task accounting file: none Tracked task resources: extended Untracked task resources: none Process accounting: inactive Process accounting file: none Tracked process resources: extended Untracked process resources: host,mstate Flow accounting: inactive Flow accounting file: none Tracked flow resources: extended Untracked flow resources: none
