La solita spiegazione per un elevato carico medio con poco utilizzo della CPU in Linux è troppa I / O (o sonno più ininterrottamente corretto ).
Ho un servizio in esecuzione su un cluster di macchine virtuali a 2 core che mostrano un utilizzo della CPU modesto (~ 55-70% inattivo) ma superiore a 2 medie di carico mentre si verificano quasi IO, switch di contesto modesti e nessuno scambio. Polling con ps
non vedo mai D
nella colonna dello stato del processo.
Il servizio è ruby 1.9 in esecuzione sotto unicorno. Si collega a due database postgres upstream che stanno eseguendo esecuzioni di istruzioni avg molto veloci (~ 0,5 ms). Il servizio sta registrando durate delle richieste scadute circa il doppio della produzione rispetto a un carico di stress maggiore sulla nostra rete di test delle prestazioni. L'unico segnale di monitoraggio che sembra fuori portata è la media del carico (e ovviamente la durata della risposta media), tutto il resto (CPU, memoria, io, rete, interruttore, intr) è proiezioni nominali e corrispondenti.
Il sistema è Ubuntu 10.04.4 LTS "Lucido". uname è Linux dirsvc0 2.6.32-32-server #62-Ubuntu SMP Wed Apr 20 22:07:43 UTC 2011 x86_64 GNU/Linux
. Hypervisor è VMWare ESX 5.1.
AGGIORNAMENTO: Ulteriori informazioni come richiesto da @ewwhite. L'archiviazione è un dispositivo a disco virtuale associato a un innesto NFS sull'host vm collegato a NetApp. Sottolineerò che tutte le indicazioni indicano che non si sta verificando un significativo IO del disco. Il servizio legge e scrive sui socket di rete (~ 200 KB / s) e esegue l'accesso normale e la registrazione degli errori (a una velocità di circa 20 KB / s). L'host vm ha una coppia di porte gigabit che vanno su due switch rack superiori, ognuno dei quali ha collegato quattro porte gigabit a un router core, tutto in rame. Ogni host VM ha 24 (4x6) core fisici e 150 GB di memoria e in genere ospita circa 30 guest VM di dimensioni simili che eseguono una varietà di servizi diversi. Nella produzione questi host non sono mai sottoposti a commit eccessivo in memoria e solo in modo modesto in CPU.
Gradirei idee per spiegare l'alto carico.
Ecco alcuni estratti dei dati sar da un mezzogiorno di due ore oggi:
