Memória Livre no AIX
Criar um arquivo showFreeMemory.sh
vi showFreeMemory.sh
colar esse conteúdo:
memory=`prtconf -m | awk 'BEGIN {FS=" "} {print $3/1024}'`
usedmem=`svmon -G | grep memory | awk 'BEGIN {FS=" "} {print $3/256/1024}'`
freemem=`echo $memory-$usedmem | bc -l`
# Conclusion
echo "Avai Mem: $memory GB"
echo "Free Mem: $freemem GB"
echo "Used Mem: $usedmem GB"
Salvar
Alterar a permissão
chmod 755 showFreeMemory.sh
saida é isso:
Avai Mem: 8 GB Free Mem: 2.24053 GB Used Mem: 5.75947 GB 16:29:02
