linux 下監控keepalived進程

ps -ef | grep  "keepalived" | grep -v grep | awk '{print $2}'| wc -l

ps -ef                               顯示全部進程

grep "keepalived"           顯示包含「keepalived」的行

grep -v grep                   排除顯示包含grep的行

awk '{print $2}'               按須要篩選文本，本例是顯示第二列（可選）

wc -l                                統計行數
