Titolo: Tuning sistema Linux ... ossia ?

Salve a tutti, mi sto imbattendo in sempre più annunci di lavoro che
richiedono "Esperienza nel tuning di server Linux". 
Posto che ovviamente, è un'attività da amministratore "navigato", 
vorrei solo chiedervi quali sono i comandi e gli strumenti che ad
esempio usate per fare il tuning (nice? ...etc) . 
Mi bastano i nomi, poi me li vado a spulciare io ... 
Grazie in anticipo
Ciao
Stighy

 esempio usate per fare il tuning (nice? ...etc) .
E' un termine abbastanza vago. Significa tutto e nulla. Volendo dare una 
definizione a tutti i costi, io direi "ottimizzare le prestazioni per 
l'utilizzo che si intende fare della macchina".
Quindi...dipende. Un server web ha esigenze differenti da un database, tanto 
per dire, o da un server usato come host per la virtualizzazione. 
Piu' che specifici comandi, a livello software molto spesso si interviene ad 
esempio nel kernel, modificando opportunamente certi parametri che 
riguardano la gestione interna delle risorse, come alcuni parametri che 
stanno in /proc (gestione memoria virtuale, scheduling di CPU e I/O, 
modifica di parametri riguardanti la rete, come numero di porte da usare, 
buffer TCP, o centomila altre cose).
Ovviamente si puo' anche intervenire a livello hardware, quindi, sempre 
sapendo cio' che il server deve fare, si puo' espandere la RAM, montare 
dischi piu' grandi o in RAID, aggiungere schede di rete, aggiungere altri 
server in clustering, e (anche qui) altre centomila cose.
Alla base di tutto c'e' pero' sempre la conoscenza di cio' che il server e 
le applicazioni che ci girano sopra devono fare. TUTTO e' relativo a quello, 
e il tuning va fatto di conseguenza.

Cio' che si vede, e'.

 
Ovviamente, attendersi una risposta concreta e non arrogante, è chiedere
troppo in questo ng. 
Per chi possa esserne interessato sto leggendo questo interessante
articolo: 
http://www.linuxforums.org/articles/linux-performance-tuning_107.html
Tra i vari comandi si citano ad esempio: ps, vmstat, hdparm, Sysctl
etc. 

 troppo in questo ng.
Veramente piu` che arrogante, la risposta mi e` sembrata sintetica e
assai pertinente, mentre la tua denota mancanza di comprensione di
quanto ti e` stato detto (non solo da Davide). Inoltre sei
platealmente sprovvisto di spirito BOFH e senza di questo non potrai
arivare da nessuna parte.

Se ad una domanda uno risponde "usa il cervello" mi sembra proprio una
risposta del c***o ed... arrogante .. 
Comunque finiamola qua ... non ho voglia di fare polemiche
kilometriche..
Eviterò l'uso di questo newsgroup per far domande, l'ho capito da
tempo ..  mi limiterò a rispondere agli sventurati che ci capitano in
cerca di risposte... sempre se ne avrò le competenze  ...

 arivare da nessuna parte.

 risposta del c***o ed... arrogante .. 
Ok.
Se ti dico che uno dei principali strumenti per il tuning di una
macchina è "vi" tu come reagisci?
E se ti dico che un altro strumento indispensabile è "ls" mi dai
del matto, vero?

Tralasciando Zamboni che come sempre non merita risposta nella sua
inutilità (e non è il primo thread che non ne merita),  dico solo che
sono risposte inutili e supponenti .. 
La risposta utile (e non solo a me ma a tutti) poteva essere: "carissimo
utente, alcuni strumenti e comandi sono ps, vmstat, hdparm, Sysctl,
glxgears, poi lascio a te cercare su google ... "

 glxgears, poi lascio a te cercare su google ... "
No.
La risposta giusta, anche se a te non va giù, è quella di davide.
Il tuning dipende dal compito della macchina che devi analizzare.
Quelli che hai elencato sono un misto tra strumenti di analisi e
strumenti di tuning.
E gli strumenti di analisi sono tutti i comandi di sistema, quello
di tuning è al 90% vi.

EH  GRAZIE ALLA CIORLA .. COSA "TUNIZZO" (perdonate il francesismo) se
prima non analizzo ...  ?!?!?!?!??!?
E la mia risposta è comunque e di sicuro PIU' UTILE che la risposta di
DAVIDE ... 
Ah dimenticavo di dirti ... "Usa il cervello" ...

 inutilità (e non è il primo thread che non ne merita)
ROTFL, adesso ho capito il tuo problema con la risposta di Davide: tu il 
cervello non ce l'hai :-)
porello, addio

 risposta del c***o ed... arrogante ..
Sbagli,una risposta arrogante e' "che cazzo vuoi fare,che non capisci una 
minchia!",chiaro ?
Davide ha semplicemente sintetizzato un'argomento immenso.

 cerca di risposte... sempre se ne avrò le competenze  ... 
Mi auguro solo che la qualità delle risposte sia superiore a quella delle 
domande. Un prof. di filosofia, oltre 20 anni fa, diceva che era molto più 
difficile fare delle buone domande che dare delle buone risposte.

C'era un articolo (forse di una serie) proprio sul tuning sull'ultimo
LJ.
In ogni caso attento a non confondere le posate con quello che hai nel
piatto (come ti hanno gia` fatto notare in diversi), perche' solo con
le prime non riusciresti a mangiare molto (per niente), mentre senza
di esse ma con qualcosa nel piatto, comunque riusciresti a mangiare.
