Ịwụnye Atop Monitoring Tool na Linux

1. N'isiokwu a, m ga-egosi gị otu esi wụnye na hazi atop na Linux usoro dị ka RHEL/CentOS/Fedora na Debian/Ubuntu dabeere usoro, nke mere na ị nwere ike mfe nyochaa gị usoro usoro.

Nke mbụ, ị ga-eme ka ebe nchekwa epel dị n'okpuru RHEL/CentOS/ sistemu, ka ịwụnye ngwa nleba anya atop.

Mgbe ịmechara ebe nchekwa epel, ị nwere ike iji njikwa ngwugwu yum dị mfe iji wụnye ngwugwu atop dị ka egosiri n'okpuru.

# yum install atop

N'aka nke ọzọ, ịnwere ike budata ngwugwu rpm ozugbo site na iji iwu wget wee gaa n'ihu na ntinye nke atop, yana iwu a.

------------------ For 32-bit Systems ------------------
# wget http://www.atoptool.nl/download/atop-2.1-1.i586.rpm
# rpm -ivh atop-2.1-1.i586.rpm

------------------ For 64-bit Systems ------------------
# wget http://www.atoptool.nl/download/atop-2.1-1.x86_64.rpm
# rpm -ivh atop-2.1-1.x86_64.rpm

N'okpuru sistemụ dabere na Debian, enwere ike itinye atop site na ebe nchekwa ndabara site na iji apt-nweta iwu.

$ sudo apt-get install atop

2. Mgbe wụnye atop, jide n'aka na atop ga-amalite n'elu usoro malite, na-agba ọsọ ndị a iwu:

------------------ Under RedHat based systems ------------------
# chkconfig --add atop
# chkconfig atop on --level 235

$ sudo update-rc.d atop defaults             [Under Debian based systems]

3. Site na ndabara atop ga-abanye ọrụ niile na sekọnd 600 ọ bụla. Ebe ọ bụ na nke a nwere ike ọ gaghị aba uru, m ga-agbanwe nhazi nke atop, ya mere, a ga-abanye ihe omume niile na nkeji 60. Maka ebumnuche ahụ gbasoo iwu a:

# sed 's/600/60/' /etc/atop/atop.daily -i                [Under RedHat based systems]
$ sudo sed 's/600/60/' /etc/default/atop -i              [Under Debian based systems]

Ugbu a i tinyegoro n'elu ma hazie ya, ajụjụ ezi uche na-esote bụ \Olee otu m ga-esi eji ya? N'ezie enwere ụzọ ole na ole maka nke ahụ:

# atop -p

11. Nchịkọta kwa onye ọrụ - \u igodo - ihuenyo a na-egosi ndị ọrụ nọ/na-arụ ọrụ n'oge oge ikpeazụ ma na-egosi usoro ole onye ọrụ ọ bụla na-agba ọsọ.

# atop -u

12. Ojiji netwọk - \n igodo (chọrọ netatop kernel modul) na-egosi ọrụ netwọk kwa usoro.

Iji wụnye ma na-arụ ọrụ netatop kernel modul, ị ga-enwerịrị ngwungwu ndabere ndị a etinyere na sistemụ gị site na ebe nchekwa nkesa.

# yum install kernel-devel zlib-devel                [Under RedHat based systems]
$ sudo apt-get install zlib1g-dev                    [Under Debian based systems]

Ọzọ budata netatop tarball wee wuo modul na daemon.

# wget http://www.atoptool.nl/download/netatop-0.3.tar.gz
# tar -xvf netatop-0.3.tar.gz

Gaa na ndekọ 'netatop-0.3' wee mee iwu ndị a ka ịwụnye ma wuo modul.

# make
# make install

Mgbe arụnyere netatop modul nke ọma, buo modul ma malite daemon.

# service netatop start
OR
$ sudo service netatop start

Ọ bụrụ na ịchọrọ ịkwanye modul na-akpaghị aka mgbe buut, mee otu n'ime iwu ndị a dabere na nkesa.

# chkconfig --add netatop                [Under RedHat based systems]

Ugbu a lelee ojiji netwọkụ site na iji igodo \n.
