accounting - How can I enable pid and ppid fields in psacct dump-acct?

itemprop="text">


I am currently using the
psacct package on Centos to perform accounting on processes run by
users.



The info file href="http://www.gnu.org/software/acct/manual/html_chapter/accounting_7.html#SEC24"
rel="nofollow noreferrer">1 suggests that it is possible to output pid and
ppid depending on what information your operating system provides in it's struct
acct.



pid and ppid are listed in
/usr/include/linux/acct.h on my
system:



struct
            acct_v3
{
 char ac_flag; /* Flags */

 char
            ac_version; /* Always set to ACCT_VERSION */
 __u16 ac_tty; /* Control
            Terminal */
 __u32 ac_exitcode; /* Exitcode */
 __u32 ac_uid; /*
            Real User ID */
 __u32 ac_gid; /* Real Group ID */
 __u32 ac_pid; /*
            Process ID */
 __u32 ac_ppid; /* Parent Process ID
            */
...



But
pid and ppid are not output when I run
dump-acct:

Is it likely that
there is no support in my kernel for this feature or that my psacct version does not
support this?



How can I add pid and ppid to my
accounting logs?



CentOS release
5.6




Kernel
2.6.18-238.19.1.el5



psacct
6.3.2



Answer




I just found this in the href="http://pkgs.org/centos-6-rhel-6/centos-rhel-i386/psacct-6.3.2-63.el6.i686.rpm.html"
rel="nofollow noreferrer">changelog for the psacct
RPM:



* Fri Nov 13 2009
            Ivana Varekova  - 6.3.2-56
 - fix the psacct to
            deal with all acct types and
 if it is possible and wanted then add the
            possibility

 to display the pid and ppid
            number


So it looks
like it depends in exactly which release you are using.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...
