一些shell 收集

获取多个pod的错误日志及数量统计

#!/bin/sh

if [ $1 ];then
    if [ $2 ];then
        if [ $3 ];then
            for i in `kubectl get po -n $1 | grep -i $2 | awk 'NR>=2 {print $1}'`
            do
            printf "%-40s Exception:%-10s Error:%-10s\n" $i `kubectl logs -n $1 $i -c $3 | grep -i Exception|wc -l` `kubectl logs -n $1 $i -c $3 | grep -i error |wc -l`
            done
        else
            echo "please input the container name"
        fi
    else
        echo "please input the pod name"
    fi
else
  echo "please input the namespace"
fi

在docker容器中获取一些java运行时信息

#!/bin/bash
pid=`jps | grep my-app |awk '{print $1}'`

for i in $(seq 10)
do
    top -Hp $pid -n 2 > /app/top_$i.log;
    /usr/lib/java/latest/bin/jstack -l $pid > /home/jeeapp/stack$i.log
    if [ `expr $i % 5` -eq 0 ]
    then
        /usr/lib/java/latest/bin/jmap -dump:format=b,file=/app/$pid_$i.hprof $pid
    fi
    sleep 60
    echo "please waiting for completed.... $i minute passed"
done
