check ram libera server unix
Salve a tutti,
c'è una cosa su cui mi sbatto da un paio di giorni.
Sto lavorando su un server linux e non riesco a capire perchè lanciando
il comando free
[pippo@srvdw pippo]$ free
total used free shared buffers cached
Mem: 3934216 3845296 88920 0 4900 3265884
-/+ buffers/cache: 574512 3359704
Swap: 8388472 0 8388472
correggetemi se sbaglio ma da qui vedo che ho quasi tutta la ram occupata.giusto?
se vedo il dettaglio con i processi
[pippo@srvdw pippo]$ ps -aux | awk '{print $2,$3,$4}'

se faccio la somma della terza colonna ho un consumo totale del 64%.
Per quale motivo? non dovrebbero coincidere?
e se no come faccio a vedere tutti i processi e il loro consumo cosicchè da
fare un po di pulizia.
grazie tante
Marco
