DEPENDENCIES

------------

Install the following packages to be able to build atop (package name

can be different depending on the Linux distro):

* zlib-devel    or libz-dev or zlib1g-dev

* ncurses-devel or libncurses5-dev/libncursesw5-dev

* glib2-devel   or libglib2.0-dev

Install the following packages to be able to execute atop (package name

can be different depending on the Linux distro):

* zlib    or zlib1g

* ncurses or libncurses5/libncursesw5

* glib2   or libglib2.0

INSTALLING AND USING ATOP FROM TARBALL

--------------------------------------

For interactive use, it is sufficient to install ATOP with the command

(as root):

	make install		(systemd based)

		or

	make sysvinstall	(System V init based)

For automatic logging in compressed binary format, see the

description in the manual-page.

NETWORK-RELATED COUNTERS PER PROCESS/THREAD

-------------------------------------------

The kernel module 'netatop' can be downloaded and installed separately

from www.atoptool.nl/downloadnetatop.php

This module is optional and can be used to gather network statistics

per process/thread as described in www.atoptool.nl/netatop.php

Alternatively, the BPF implementation 'netatop-bpf' can be downloaded

and installed from https://github.com/bytedance/netatop-bpf

PROCESS ACCOUNTING WITH PSACCT/ACCT PACKAGE

-------------------------------------------

Preferably, process accounting should be handled by the atopacctd daemon

which is implicitly installed when installing atop. This daemon takes

care that process accounting is only active when at least one atop

process is running. Besides, when process accounting is activated,

atopacctd takes care that the disk utilization is minimal.

See the man page of atopacctd for further details.

When the psacct or acct package is installed in parallel with the

atop package and you want to enable/start the (ps)acct service for

permanent process accounting, the atopacct.service refuses to activate

the atopacctd daemon to avoid clashes.

When the (ps)acct service is enabled, atop automatically uses the

process accounting file that is used by this package.

See also the section PROCESS ACCOUNTING in the man page of atop.

OVERVIEW OF RELATED PROGRAMS

----------------------------

When installing atop the following programs are provided:

  atop        - System and process monitor (live and from raw log)

  atopacctd   - Daemon: handles process accounting records to be used by atop

  atopgpud    - Daemon: gathers metrics from Nvidia GPUs to be used by atop

  atopsar     - System activity reports (live and from raw log)

  atopcat     - Concatenate raw log files and provide raw log information

  atophide    - Make extractions from raw logs and/or anonymize raw logs

  atopconvert - Convert raw log to newer version

SERVICE ACTIVATION AFTER INSTALLATING PACKAGE

---------------------------------------------

After the package has been installed, be sure that the related services

are activated.

To support handling of terminated processes using process accounting,

enable the atopacct service:

	systemctl enable --now atopacct

Notice that this service should not be enabled when the package

psacct or acct (depends on the Linux distribution) has been installed

and enabled. In that case atop uses the daily process accounting file

created via that package.

To support maintaining daily log files to keep track of long-term analysis

information, enable the atop service and the related timer:

	systemctl enable --now atop

	systemctl enable --now atop-rotate.timer
