Na semana passada, precisei monitorar e identificar problemas de latência nos discos que compõem o ASM de um servidor Oracle Database em produção. Durante minhas pesquisas, não encontrei nenhuma solução pronta que atendesse a essa necessidade. Diante disso, desenvolvi o script abaixo, que pode ser útil para outros profissionais que enfrentem situações semelhantes.
O script ira realizar o refresh a cada 5 segundos:
iostat -xnz 5 | nawk '
BEGIN {
print "------------------------------------------------------------------------------------------------------------------------------"
printf "%-15s | %-6s | %-6s | %-11s | %-9s | %-7s | %-9s | %s\n", "DEVICE", "IOPS", "MB/s", "AVG SZ", "LATENCY", "BUSY", "STATUS", "DATE"
print "------------------------------------------------------------------------------------------------------------------------------"
}
!/device/ && !/extended/ && NF > 2 {
dev = $NF;
r_s = $1;
w_s = $2;
kr_s = $3;
kw_s = $4;
latency = $8;
busy = $10;
total_iops = r_s + w_s;
total_kb = kr_s + kw_s;
if (total_iops > 0) {
avg_io_size = total_kb / total_iops;
} else {
avg_io_size = 0;
}
if (latency > 20 || busy > 90) {
status = (latency > 50) ? "CRITICAL" : "WARNING";
cmd = "date +\"%d/%m/%Y %H:%M:%S\"";
cmd | getline agora;
close(cmd);
printf "%-15s | %-6.1f | %-6.1f | %-8.1f KB | %-6.1f ms | %s%% | %-9s | %s\n", dev, total_iops, total_kb/1024, avg_io_size, latency, busy, status, agora;
}

IOPS (r/s + w/s): IOPS (Input/Output Operations Per Second) mede quantas operações de leitura e escrita um disco ou sistema de storage consegue realizar por segundo.
MB/s (Throughput): A largura de banda consumida.
AVG SZ (Payload): Tipo de carga (Random vs. Sequential).
LATENCY (asvc_t): Latência dos discos.
- < 10ms: Saudável (Flash/Cache hit).
- 20ms – 50ms: Degradação perceptível (Wait Events de User I/O sobem).
