centos下如何查看調(diào)優(yōu)apache狀態(tài)的相關(guān)命令

1、查看apache連接數(shù)

ps aux | grep httpd | wc -l

2、實(shí)時(shí)監(jiān)控apache連接數(shù)

watch -n 1 -d "pgrep httpd|wc -l"

3、查看服務(wù)器網(wǎng)絡(luò)情況

netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'

4、查看apache占用的內(nèi)存數(shù)

ps aux|grep -v grep|awk '/httpd/{sum+=$6;n++};END{print sum/n}'
