Is the column command available at all on your system?
As it is, i suppose there isn't:

Hi All,
I am trying to find the physical memory usage by each process/users.
Can you please let me know how to get the memory usage?.
Thanks,

Hi i just wanted to know what is the code to display amount of RAM and also the percentage used? I know i can possibly use the vmstat code but what part indicates the RAM? Any help would be much appreciated. Thanks (1 Reply)
Hi
one of our applications that runs on our Linux server leaks memory resulting in Ram that was used by the program not being released back to the operating system once a file has been processed. the result is over a very short period virtual all the memory has been used. an example currently

Hi RAM of my system is 24 GB however when i checked the processes pids and counted the memory usage by pmap i found out that the total memory usage is 36 GB
It s obvious that my system might be using some of virtual memory or swap space . How can i check which memory it is using and how ..

Hi,
I will be creating a process myself and I want to know the average CPU and RAM used by the process over the lifetime of the process. I see that there are various tools available(pidstat) for doing , I was wondering if it possible to do it in a single command while creation.

cronjob_selinux
cronjob_selinux(8) SELinux Policy cronjob cronjob_selinux(8)NAME
cronjob_selinux - Security Enhanced Linux Policy for the cronjob processes
DESCRIPTION
Security-Enhanced Linux secures the cronjob processes via flexible mandatory access control.
The cronjob processes execute with the cronjob_t SELinux type. You can check if you have these processes running by executing the ps com-
mand with the -Z qualifier.
For example:
ps -eZ | grep cronjob_t
ENTRYPOINTS
The cronjob_t SELinux type can be entered via the user_cron_spool_t, shell_exec_t file types.
The default entrypoint paths for the cronjob_t domain are the following:
/var/spool/at(/.*)?, /var/spool/cron, /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/zsh.*, /usr/bin/ksh.*, /bin/esh,
/bin/mksh, /bin/sash, /bin/tcsh, /bin/yash, /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash, /usr/bin/tcsh, /usr/bin/yash,
/usr/bin/fish, /usr/bin/mksh, /usr/bin/bash, /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2, /usr/sbin/smrsh, /usr/bin/scponly,
/usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell, /usr/libexec/git-core/git-shell
PROCESS TYPES
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux cronjob policy is very flexible allowing users to setup their cronjob
processes in as secure a method as possible.
The following process types are defined for cronjob:
cronjob_t
Note: semanage permissive -a cronjob_t can be used to make the process type cronjob_t permissive. SELinux does not deny access to permis-
sive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. cronjob policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run cronjob with the tightest access possible.
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
MANAGED FILES
The SELinux process type cronjob_t can manage files labeled with the following file types. The paths listed are the default paths for
these file types. Note the processes UID still need to have DAC permissions.
user_home_t
/home/[^/]*/.+
user_tmp_t
/var/run/user(/.*)?
/tmp/hsperfdata_root
/var/tmp/hsperfdata_root
/tmp/gconfd-.*
COMMANDS
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
