Segue anexo o pequeno patch pra net taskstats accounting. Exemplo de userland: [root][hm2306][.c0] # cat ustatsd.log | grep -i comlines1 { "host" : "hm2306", "uid" : "11606", "name" : "comlines1", "time" : "2010:05:12:13:44", "ucpu" : "29864000", "pucpu" : "49.77", "scpu" : "5936000", "pscpu" : "9.89", "mem" : "1727.23" } { "host" : "hm2306", "uid" : "11606", "name" : "comlines1", "time" : "2010:05:12:13:45", "ucpu" : "30180000", "pucpu" : "50.29", "scpu" : "5236000", "pscpu" : "8.73", "mem" : "1535.17" } { "host" : "hm2306", "uid" : "11606", "name" : "comlines1", "time" : "2010:05:12:13:46", "ucpu" : "33064000", "pucpu" : "55.11", "scpu" : "5892000", "pscpu" : "9.82", "mem" : "1669.16" } O PUCPU eh porcentagem de utilizacao (ncpus * 100) e o PSCPU eh porcentagem de utilizacao de system do mesmo uid. Memoria hoje em dia eh um high watermark de todos procs que estao ativos e/ou morreram no timequantum medido. O userland gera um xmpp em json de mais de 1500 usuários por máquinas falando o consumo total de cpu, memoria, disco e (com meu patch) rede. Tem um frontend que gera os graficos de utilizacao de recursos por usuário.
