zjtest7-frontend:/usr/local/logstash-2.3.4/config# cat g01.conf
input {stdin{}}
filter {
grok {
match => {
"message" =>"\s+(?<request_time>\d+(?:\.\d+)?)\s+"
}
}
mutate {
convert => [ "request_time", "float"]
}
}
output {
stdout {
codec => rubydebug{}
}
} zjtest7-frontend:/usr/local/logstash-2.3.4/config# ../bin/logstash -f g01.conf
Settings: Default pipeline workers: 1
Pipeline main started
begin 123.456 end
{
"message" => "begin 123.456 end",
"@version" => "1",
"@timestamp" => "2016-09-11T05:31:32.576Z",
"host" => "0.0.0.0",
"request_time" => "123.456"
} 此时 "request_time" => "123.456" 输出的是字符串 zjtest7-frontend:/usr/local/logstash-2.3.4/config# cat g01.conf
input {stdin{}}
filter {
grok {
match => {
"message" =>"\s+(?<request_time>\d+(?:\.\d+)?)\s+"
}
}
mutate {
convert => [ "request_time", "float"]
}
}
output {
stdout {
codec => rubydebug{}
} zjtest7-frontend:/usr/local/logstash-2.3.4/config# ../bin/logstash -f g01.conf
Settings: Default pipeline workers: 1
Pipeline main started
begin 123.456 end
{
"message" => "begin 123.456 end",
"@version" => "1",
"@timestamp" => "2016-09-11T05:34:13.040Z",
"host" => "0.0.0.0",
"request_time" => 123.456
} 把字符串转换为 float型
