\n0. \u00davod, alebo trochu odbo\u010denia<\/b>Tento \u010dl\u00e1nok vznikol len preto, \u017ee je extr\u00e9mne \u0165a\u017ek\u00e9 n\u00e1js\u0165 porovn\u00e1vacie charakteristiky podobn\u00e9ho softv\u00e9ru, niekedy aj len zoznam, na jednom mieste. Je potrebn\u00e9 prejs\u0165 mno\u017estvo materi\u00e1lu, aby sme dospeli aspo\u0148 k nejak\u00e9mu z\u00e1veru.<\/p>\n

V s\u00favislosti s t\u00fdm som sa rozhodol trochu u\u0161etri\u0165 \u010das a \u00fasilie t\u00fdch, ktor\u00fdch t\u00e1to ot\u00e1zka zauj\u00edma, a zhroma\u017edil na jednom mieste maxim\u00e1lne mo\u017en\u00e9, \u010d\u00edtaj, \u010do som zvl\u00e1dol, mno\u017estvo syst\u00e9mov pre network mapping.<\/p>\n

Niektor\u00e9 syst\u00e9my pop\u00edsan\u00e9 v tomto \u010dl\u00e1nku som osobne vysk\u00fa\u0161al. Je pravdepodobn\u00e9, \u017ee ide o zastaran\u00e9 verzie. Niektor\u00e9 z ni\u017e\u0161ie uveden\u00fdch syst\u00e9mov vid\u00edm prv\u00fdkr\u00e1t a inform\u00e1cie o nich boli zhroma\u017e\u010fovan\u00e9 v\u00fdhradne v r\u00e1mci pr\u00edpravy tohto \u010dl\u00e1nku.<\/p>\n

Ke\u010f\u017ee som sa t\u00fdchto syst\u00e9mov dot\u00fdkal d\u00e1vno a niektor\u00e9 z nich som v\u00f4bec nesk\u00famal, \u017eiadne sn\u00edmky obrazovky alebo pr\u00edklady mi nezostali. Tak\u017ee som si osvie\u017eil vedomosti cez Google, Wikip\u00e9diu, YouTube, str\u00e1nky v\u00fdvoj\u00e1rov, tam som na\u0161iel aj sn\u00edmky obrazovky, a nakoniec vznikol tento preh\u013ead.<\/p>\n

<\/p>\n

1. Te\u00f3ria<\/h2>\n

<\/p>\n

1.1. Pre\u010do?<\/h3>\n

\nAby sme odpovedali na ot\u00e1zku \"Pre\u010do?\", najprv mus\u00edme pochopi\u0165, \u010do je \"Mapa siete\". Mapa siete je (\u010dastej\u0161ie) logicko-grafick\u00e9-schematick\u00e9 zobrazenie vz\u00e1jomn\u00e9ho p\u00f4sobenia sie\u0165ov\u00fdch zariaden\u00ed a ich prepojen\u00ed, ktor\u00e9 popisuje ich najv\u00fdznamnej\u0161ie parametre a vlastnosti. V s\u00fa\u010dasnosti sa \u010dasto pou\u017e\u00edva v spojen\u00ed s monitorovan\u00edm stavu zariaden\u00ed a syst\u00e9mom upozornen\u00ed. Cie\u013eom je ma\u0165 predstavu o umiestnen\u00ed uzlov siete, ich interakcii a vz\u0165ahoch medzi nimi. V spojen\u00ed s monitorovan\u00edm m\u00e1me pracovn\u00fd n\u00e1stroj na diagnostiku spr\u00e1vania sa a predpovedanie spr\u00e1vania siete.<\/p>\n

1.2. L1, L2, L3<\/h3>\n

\nS\u00fa to Layer 1, Layer 2 a Layer 3 pod\u013ea modelu OSI. L1 \u2013 fyzick\u00e1 \u00farove\u0148 (k\u00e1ble a komut\u00e1cia), L2 \u2013 \u00farove\u0148 fyzick\u00e9ho adresovania (mac-adresy), L3 \u2013 \u00farove\u0148 logick\u00e9ho adresovania (IP-adresy).
\n<\/a><\/noindex>
\nVytv\u00e1ra\u0165 mapu L1 v podstate nem\u00e1 zmysel, logicky vyplynie z L2, ak ner\u00e1tame mediakonvertory. A aj tie dnes existuj\u00fa mediakonvertory, ktor\u00e9 je mo\u017en\u00e9 tie\u017e sledova\u0165. <\/p>\n

Logicky - L2 vytv\u00e1ra mapu siete na z\u00e1klade mac-adres uzlov, L3 - na z\u00e1klade IP-adres uzlov.<\/p>\n

1.3. Ak\u00e9 \u00fadaje zobrazova\u0165<\/h3>\n

\nZ\u00e1vis\u00ed to od \u00faloh a po\u017eiadaviek. Mne osobne sa chce vedie\u0165, \u010di je zariadenie \"\u017eiv\u00e9\", na akom porte \u010do \"vis\u00ed\" a v akom stave je port \u2013 up alebo down. To m\u00f4\u017ee by\u0165 L2. A v\u00f4bec, L2 sa mi zd\u00e1 by\u0165 najviac aplikovate\u013enou topol\u00f3giou na mape siete. Ale, ka\u017ed\u00fd m\u00e1 svoj vkus.<\/p>\n

R\u00fdchlos\u0165 pripojenia na porte \u2013 nie je zl\u00e1, ale nie je kritick\u00e1, ak je tam koncov\u00e9 zariadenie \u2013 tla\u010diare\u0148PC. Bolo by fajn ma\u0165 mo\u017enos\u0165 pozrie\u0165 sa na \u00farove\u0148 za\u0165a\u017eenia procesora, mno\u017estvo vo\u013enej RAM a teplotu na zariaden\u00ed. Ale to u\u017e nie je tak\u00e9 jednoduch\u00e9, tu bude potrebn\u00e9 nastavi\u0165 monitorovac\u00ed syst\u00e9m, ktor\u00fd dok\u00e1\u017ee \u010d\u00edta\u0165 SNMP a analyzova\u0165 z\u00edskan\u00e9 d\u00e1ta. O tom nesk\u00f4r.<\/p>\n

\u010co sa t\u00fdka L3, na\u0161iel som toto \u010dl\u00e1nok<\/a><\/noindex>. <\/p>\n

1.4. Ako?<\/h3>\n

\nM\u00f4\u017ee sa to robi\u0165 ru\u010dne, alebo automaticky. Ak ru\u010dne \u2013 tak to trv\u00e1 dlho a je potrebn\u00e9 zoh\u013eadni\u0165 \u013eudsk\u00fd faktor. Ak automaticky \u2013 je potrebn\u00e9 zoh\u013eadni\u0165, \u017ee v\u0161etky sie\u0165ov\u00e9 zariadenia musia by\u0165 \"inteligentn\u00e9\", vedie\u0165 SNMP a tento SNMP mus\u00ed by\u0165 spr\u00e1vne nastaven\u00fd, aby syst\u00e9m, ktor\u00fd bude zhroma\u017e\u010fova\u0165 \u00fadaje z nich, mohol tieto \u00fadaje na\u010d\u00edta\u0165.<\/p>\n

Na prv\u00fd poh\u013ead to nie je zlo\u017eit\u00e9. Ale s\u00fa tu skryt\u00e9 \u00faskalia. Za\u010d\u00edna to t\u00fdm, \u017ee nie ka\u017ed\u00fd syst\u00e9m dok\u00e1\u017ee zo zariadenia na\u010d\u00edta\u0165 v\u0161etky \u00fadaje, ktor\u00e9 by sme chceli vidie\u0165, alebo nie v\u0161etky sie\u0165ov\u00e9 zariadenia dok\u00e1\u017eu tieto \u00fadaje poskytn\u00fa\u0165, a kon\u010d\u00ed to t\u00fdm, \u017ee nie ka\u017ed\u00fd syst\u00e9m dok\u00e1\u017ee automaticky vytv\u00e1ra\u0165 mapy siete.<\/p>\n

Proces automatick\u00e9ho vytv\u00e1rania mapy je pribli\u017ene tak\u00fdto:<\/p>\n

\u2014 syst\u00e9m na\u010d\u00edta \u00fadaje z sie\u0165ov\u00e9ho vybavenia
\n \u2014 na z\u00e1klade \u00fadajov vytvor\u00ed pre ka\u017ed\u00fd port smerova\u010da tabu\u013eku zhodnosti adries na portoch
\n \u2014 porovn\u00e1va adresy a men\u00e1 zariaden\u00ed
\n \u2014 buduje prepojenia port-zariadenie
\n \u2014 vizualizuje to v\u0161etko vo forme sch\u00e9my, \"intuit\u00edvne pochopite\u013enej\" pre pou\u017e\u00edvate\u013ea<\/p>\n

2. Praktika<\/h2>\n

\nTak, teraz sa porozpr\u00e1vajme o tom, pomocou \u010doho m\u00f4\u017eeme vytvori\u0165 mapu siete. Za\u010dneme predpokladom, \u017ee chceme tento proces samozrejme maxim\u00e1lne automatizova\u0165. No, t.j. Paint a MS Visio vypad\u00e1vaj\u00fa\u2026 hoci\u2026 Nie, predsa len vypad\u00e1vaj\u00fa.<\/p>\n

Existuje \u0161pecializovan\u00fd softv\u00e9r, ktor\u00fd rie\u0161i \u00falohu vytv\u00e1rania mapy siete. Niektor\u00e9 softv\u00e9rov\u00e9 produkty m\u00f4\u017eu len poskytn\u00fa\u0165 prostredie pre \u201eru\u010dn\u00e9\u201c prid\u00e1vanie obr\u00e1zkov so vlastnos\u0165ami, kreslenie spojen\u00ed a sp\u00fa\u0161\u0165a\u0165 \u201emonitoring\u201c v extr\u00e9mne obmedzenej forme (\u010di je uzol \u017eiv\u00fd, alebo u\u017e nereaguje). In\u00e9 v\u0161ak dok\u00e1\u017eu nielen samostatne nakresli\u0165 sch\u00e9mu siete, ale aj po\u010d\u00edta\u0165 mno\u017estvo parametrov cez SNMP, informova\u0165 pou\u017e\u00edvate\u013ea cez SMS v pr\u00edpade por\u00fach, poskytn\u00fa\u0165 mno\u017estvo inform\u00e1ci\u00ed o portoch sie\u0165ov\u00e9ho zariadenia, a to v\u0161etko je len \u010das\u0165ou ich funkcionality (rovnako ako NetXMS).<\/p>\n

3. Porovn\u00e1vacia tabu\u013eka<\/h2>\n

\nAko sa uk\u00e1zalo, vymyslie\u0165 aktu\u00e1lne a d\u00f4le\u017eit\u00e9 parametre na porovnanie syst\u00e9mov a pritom ich zmesti\u0165 do jednej malej tabu\u013eky je dos\u0165 zlo\u017eit\u00e9. Narodil sa mi tento koncept:<\/p>\n

\"Mapy
\n
\n*Parametr \u201eUser Friendly\u201c je mimoriadne subjekt\u00edvny a to si uvedomujem. Ale inak, ako op\u00edsa\u0165 \u201enepreh\u013eadnos\u0165 a \u0165a\u017ekop\u00e1dnos\u0165\u201c, som zatia\u013e nevymyslel.<\/p>\n

**\u201eMonitorovanie nie len siete\u201c znamen\u00e1 fungovanie syst\u00e9mu ako \u201emonitorovacieho syst\u00e9mu\u201c v be\u017enom zmysle tohto term\u00ednu, teda schopnos\u0165 \u010d\u00edta\u0165 metriky z OS, hostite\u013eov virtualiz\u00e1cie, z\u00edskava\u0165 \u00fadaje z aplik\u00e1ci\u00ed v hos\u0165ovac\u00edch OS a pod. <\/p>\n

4. Osobn\u00fd n\u00e1zor<\/h2>\n

\nZ osobnej sk\u00fasenosti \u2014 pou\u017e\u00edvanie softv\u00e9ru samostatne na monitorovanie siete nevid\u00edm zmysel. Viac mi vyhovuje my\u0161lienka pou\u017ei\u0165 syst\u00e9m monitorovania v\u0161etk\u00e9ho s mo\u017enos\u0165ou vytvori\u0165 mapu siete. So Zabbixom je to... \u0165a\u017ek\u00e9. Takisto s Nagiosom a Icingou. A iba NetXMS ma v tomto oh\u013eade pote\u0161il. Hoci, ak sa zamysle\u0165 a vytvori\u0165 mapu v Zabbixe, vyzer\u00e1 to dokonca perspekt\u00edvnej\u0161ie ako NetXMS. Existuje e\u0161te Pandora FMS, PRTG, Solarwinds NTM, AdRem NetCrunch, a pravdepodobne mno\u017estvo \u010fal\u0161\u00edch, ktor\u00e9 neboli zahrnut\u00e9 do tohto \u010dl\u00e1nku, ale videl som ich len na obr\u00e1zkoch a vo vide\u00e1ch, tak\u017ee o nich nem\u00f4\u017eem poveda\u0165 ni\u010d.<\/p>\n

O NetXMS bol nap\u00edsan\u00fd \u010dl\u00e1nok<\/a><\/noindex> s mal\u00fdm preh\u013eadom schopnost\u00ed syst\u00e9mu a s mal\u00fdm n\u00e1vodom.<\/p>\n

P.S.:<\/h2>\n

\nAk som sa niekde pom\u00fdlil, a pravdepodobne som sa pom\u00fdlil, bu\u010fte tak laskav\u00ed a opravte ma v koment\u00e1roch, uprav\u00edm \u010dl\u00e1nok, aby t\u00fdm, ktor\u00fdm s\u00fa tieto inform\u00e1cie u\u017eito\u010dn\u00e9, nemuseli v\u0161etko overova\u0165 na vlastnej sk\u00fasenosti.<\/p>\n

\u010eakujem.
