i try to start logstash with config file but it can't work

ERROR:

my conf file :
input {
file {
path => ["/home/zhenqinghe/elk/testlog/*.log"]
type => "kettle_log"
start_position => "beginning"
}
}

filter {
grok {
patterns_dir => ["/home/zhenqinghe/elk/logstash-6.6.0/config/patterns"]
match => {
"message" => ["%{KETTLE_DATE}:kettle_date"]
}
}

date {
    match => ["kettle_date", "dd/MMM/yyyy:HH:mm:ss Z"]
}

}

output {
file {
path => "/home/zhenqinghe/elk/resultlog/%{host}.log"
message_format => "%{message}"
}
}

That configuration would not generate that error. Do you have any other files in the directory that contains the configuration? If you point -f at a directory then logstash will concatenate all the files in the directory to create the configuration.

"message" => ["%{KETTLE_DATE}:kettle_date"]

If you want to capture the string that matches the KETTLE_DATE pattern then that should be

"message" => ["%{KETTLE_DATE:kettle_date}"]

This is not valid either. If you want to specify the format you would use the codec option on the output.

message_format => "%{message}"

Thanks for you help!

if i have own patterns file , I just need to add patterns_dir in configuration file ？
like:

patterns_dir => ["/home/zhenqinghe/elk/logstash-6.6.0/config/patterns"]

That is correct.
