我写了一个bash脚本,它在指定的文件夹中找到CSV文件,并使用正确的配置文件将它们管道到logstash中.但是,当运行此脚本时,我遇到以下错误,说关闭进程停止,导致无限循环,直到我用ctrl c手动停止它：

当我用bash logstash -f xyz.config

input {

stdin {

id => "${LS_FILE}"

}

}

filter {

mutate {

add_field => { "foo_type" => "${FOO_TYPE}" }

add_field => { "[@metadata][LS_FILE]" => "${LS_FILE}"}

}

if [@metadata][LS_FILE] == "contacts.csv" {

csv {

separator => ";"

columns =>

[

"IOT",

"OID",

"SUM",

"XID",

"kundenid"

]

}

if [kundenid]{

mutate {

update => { "kundenid" => "n-%{kundenid}" }

}

}

}

}

output {

if [@metadata][LS_FILE] == "contacts.csv" {

file{

path => "~/contacts_file"

codec => json_lines

}

}

}

示例脚本：

LOGSTASH="/customer/app/logstash-6.2.3/bin/logstash"

for file in $(find $TARGETPATH -name *.csv) # Loop each file in given path

do

if [[ $file = *"foo"* ]]; then

echo "Importing $file"

export LS_FILE=$(basename $file)

bash $LOGSTASH -f $CFG_FILE < $file # Starting logstash

echo "file $file imported."

fi

done

我在bash脚本中导出环境变量,并将它们设置为logstash配置中的元数据,以便为不同的输入文件执行一些条件.文件中JSON的输出仅用于测试目的.
