NetPerf<\/a><\/noindex><\/h2>\n

\nAcesta este un instrument pentru evaluarea l\u0103\u021bimii de band\u0103 a re\u021belei. A fost dezvoltat de inginerii de la Hewlett-Packard. Instrumentul include<\/a><\/noindex> are dou\u0103 fi\u0219iere executabile: netserver \u0219i netclient. Pentru a efectua testul, trebuie s\u0103 le rula\u021bi pe ma\u0219ini diferite. \u00cen mod implicit, netperf folose\u0219te portul 12865, dar acesta poate fi schimbat cu ajutorul flag-ului -p. Utilitarul func\u021bioneaz\u0103 cu TCP \u0219i UDP prin BSD Sockets, DLPI, Unix Domain Sockets \u0219i IPv6.<\/p>\n

Ast\u0103zi, netperf face parte din setul de instrumente pentru benchmarking Flent<\/a><\/noindex>. De asemenea, este utilizat de un num\u0103r considerabil de companii IT, de exemplu, Red Hat<\/a><\/noindex>. Iat\u0103 cum arat\u0103 descrierea serviciului netperf \u00eentr-unul dintre exemplele pentru evaluarea performan\u021bei OpenShift:<\/p>\n

apiVersion: v1\nkind: Service\nmetadata:\n  labels:\n    app-name: netperf\n  name: netperf\n  namespace: your_project\nspec:\n  ports:\n  - port: 12865\n    protocol: TCP\n    targetPort: 12865\n  selector:\n    app-name: netperf\n  sessionAffinity: ClientIP\n  type: ClusterIP\n<\/code><\/pre>\n
\n\u00cen depozitul oficial se men\u021bioneaz\u0103 c\u0103 netperf este distribuit sub o licen\u021b\u0103 special\u0103 de la Hewlett-Packard. Cu toate acestea, autorul utilitarului \u2014 Rick Jones \u2014 afirm\u0103 c\u0103 acesta este conceput \u00een cele mai bune tradi\u021bii ale open source. De asemenea, merit\u0103 men\u021bionat c\u0103, \u00een ultima perioad\u0103, actualiz\u0103rile pentru netperf au \u00eenceput s\u0103 apar\u0103 destul de rar. Probabil, acest lucru este legat de maturitatea produsului.<\/p>\n
Netperf are analogi \u2014 de exemplu, iperf2<\/a><\/noindex> \u0219i iperf3<\/a><\/noindex>. Acestea permit de asemenea testarea l\u0103\u021bimii de band\u0103 a re\u021belei. Dezvoltarea iperf3 a \u00eenceput dup\u0103 ce depozitul iperf2 a intrat \u00een declin. Noua versiune este scris\u0103 de la zero \u0219i nu este compatibil\u0103 cu implementarea anterioar\u0103, de\u0219i con\u021bine o parte din codul ei. Ce este interesant, dup\u0103 lansarea iperf3, activitatea asupra iperf2 a re\u00eenceput. \u00cen cele din urm\u0103, cele dou\u0103 instrumente dispun de<\/a><\/noindex> func\u021bionalitate similar\u0103, dar \u00een acela\u0219i timp diferit\u0103. De exemplu, iperf2 este multi-threaded, iar iperf3 este lucreaz\u0103<\/a><\/noindex> doar cu un singur fir.<\/p>\n
Hardinfo<\/a><\/noindex><\/h2>\n
\nEste un utilitar pentru colectarea informa\u021biilor despre hardware \u0219i sistemul de operare. Acesta afi\u0219eaz\u0103 date despre func\u021bionarea dispozitivelor pe: PCI, ISA PnP, USB, IDE, SCSI, precum \u0219i pe por\u021bi seriale \u0219i paralele. Dar poate fi folosit \u0219i ca benchmark \u0219i instrument de monitorizare.<\/p>\n
HardInfo ofer\u0103 c\u00e2teva teste. De exemplu, CPU Blowfish evalueaz\u0103 performan\u021ba procesorului prin algoritmi criptografici de criptare simetric\u0103 bazat\u0103 pe blocuri. Exist\u0103 CPU N-Queens<\/a><\/noindex> \u2014 un test din combinatoric\u0103. Sistemul rezolv\u0103 problema plas\u0103rii a N regine pe o tabl\u0103 N x N de p\u0103trate. El a\u0219eaz\u0103 piesele astfel \u00eenc\u00e2t niciuna dintre ele s\u0103 nu poat\u0103 ataca celelalte. De asemenea, merit\u0103 men\u021bionat FPU FFT \u2014 un test pentru calculul rapid al transform\u0103rii Fourier discrete \u0219i FPU Raytracing \u2014 calculul ray tracing-ului \u00een timpul rand\u0103rii unei scene 3D.<\/p>\n
Rezultatul \u00een majoritatea testelor se ofer\u0103 \u00een secunde \u0219i, prin urmare, cu c\u00e2t acesta este mai mic, cu at\u00e2t mai bine. Toate rapoartele sunt prezentate \u00een formate HTML \u0219i txt.<\/p>\n
Ini\u021bial, utilitarul a fost dezvoltat \u00een cadrul proiectului BerliOS<\/a><\/noindex>. Acesta includea o platform\u0103 de hosting pentru aplica\u021bii cu surs\u0103 deschis\u0103 (precum SourceForge<\/a><\/noindex>) \u0219i c\u00e2teva baze de date pentru documenta\u021bie \u0219i profiluri de dezvoltatori open source. BerliOS a fost \u00eenchis \u00een 2014 din cauza lipsei de finan\u021bare. Ast\u0103zi, HardInfo se dezvolt\u0103 prin eforturile entuzia\u0219tilor \u00eentr-un depozit separat<\/a><\/noindex> pe GitHub.<\/p><\/blockquote>\n
\nS\u0103 not\u0103m c\u0103 \u00een func\u021bionarea sistemului apar uneori erori. Exist\u0103 cuno\u0219tin\u021be despre erori de segmentare ocazionale<\/a><\/noindex>, probleme cu afi\u0219area dispozitivelor USB<\/a><\/noindex> \u0219i c\u00e2teva altele<\/a><\/noindex>.<\/p>\n
ApacheBench<\/a><\/noindex><\/h2>\n
\nUn instrument pentru testarea de \u00eenc\u0103rcare a serverelor HTTP. ApacheBench (AB) a fost dezvoltat pentru testarea Apache, dar poate func\u021biona pe orice alt server. Instrumentul este preinstalat pe multe distribu\u021bii Linux.<\/p>\n

Utilitarul \"bombardiereaz\u0103\" serverele cu un num\u0103r mare de cereri. Pentru a rula, trebuie introdus\u0103 urm\u0103toarea comand\u0103:<\/p>\n
ab -n 100 -c 10 http:\/\/www.example.com\/<\/code><\/pre>\n
\nAceasta va trimite o sut\u0103 de cereri GET (subliniind c\u0103 vor fi trimise simultan maximum zece dintre ele) c\u0103tre resursa de testare. La ie\u0219ire, sistemul va afi\u0219a timpul mediu de procesare a cererilor, volumul total de date transmise, l\u0103\u021bimea de band\u0103 \u0219i num\u0103rul de erori.<\/p>\n
Ast\u0103zi, \u00een jurul utilitarului s-a adunat o comunitate extins\u0103. Online apar regulat ghiduri noi<\/a><\/noindex> despre cum s\u0103 configur\u0103m \u0219i s\u0103 folosim ApacheBench.<\/p><\/blockquote>\n

De exemplu, permite generarea de solicit\u0103ri de pe mai multe computere, gestion\u00e2nd procesul de pe unul dintre acestea. De asemenea, programul include mecanisme de autorizare pentru utilizatori virtuali, sus\u021bine sesiuni personalizate. Acest instrument este folosit de multe companii IT, inclusiv<\/a><\/noindex> provideri de cloud, de exemplu Qualys<\/a><\/noindex>.<\/p>\n
