容器资源绑定和查看

news 2025/5/23 8:31:32

CPU部分

查看容器的绑核情况

docker inspect --format='{{.HostConfig.CpusetCpus}}' mysql483-tz-webshard2-m1-4483

查看这台物理机上哪些核没绑

docker ps -q | xargs -I {} docker inspect {} --format '{{.Id}}: {{.HostConfig.CpusetCpus}}'

然后将结果copy导deepseek询问

CPU绑定

docker update --cpuset-cpus='0-15' mysql492-tz-settlementcenter-m1-4492

docker update --cpuset-cpus='1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59,61,63,65,67,69,71,73,75,77,79' mysql307-tz-productcenter-m1-4307

CPU绑核验证

docker inspect --format='{{.HostConfig.CpusetCpus}}' mysql483-tz-webshard2-m1-4483

内存部分

查看内存绑核情况

docker inspect --format='{{.HostConfig.Memory}}' mysql307-tz-productcenter-m1-4307

内存绑定

docker update --memory 32g --memory-swap 32g mysql307-tz-productcenter-m1-4307

查看容器资源使用率

查看CPU和内存

docker stats mysql492-tz-settlementcenter-m1-4492

留痕查看

for x in {1..30};do docker stats mysql492-tz-settlementcenter-m1-4492 --no-stream;sleep 1;done

查看IOPS

sar -d -p 1 30 | grep nvme1n1

查看网络带宽

#!/bin/bash# 定义监控的网卡名称
INTERFACE="bond0"# 初始化变量
prev_rx=0
prev_tx=0# 获取初始字节数
get_bytes() {cat /proc/net/dev | grep "$INTERFACE" | awk '{print $2, $10}'
}# 主循环
while true; do# 获取当前接收和发送的字节数current_rx_tx=$(get_bytes)current_rx=$(echo "$current_rx_tx" | awk '{print $1}')current_tx=$(echo "$current_rx_tx" | awk '{print $2}')# 计算与上一次的差值（即每秒的流量）if [ "$prev_rx" -ne 0 ]; thenrx_diff=$((current_rx - prev_rx))tx_diff=$((current_tx - prev_tx))total_bytes=$((rx_diff + tx_diff))# 转换为 MB（1 MB = 1024 * 1024 字节）total_mb=$(echo "scale=2; $total_bytes / (1024 * 1024)" | bc)# 输出结果echo "$(date '+%Y-%m-%d %H:%M:%S') [${INTERFACE}] Total Bandwidth: ${total_mb} MB/s"fi# 更新上一次的值prev_rx=$current_rxprev_tx=$current_tx# 等待 1 秒sleep 1
done
