Hi , I am stuck in parsing the date field in CSV and tried my best but no luck.

CSV contains 2 fields, Data and Responsetime (separated by comma) and I want to plot graph in KIBANA with x axis as Date and response as Y axis. I am able to load the data to elastic search through logstash but it is failing with Date parsing.

Sample format of CSV  
2017-04-20 10:00:01.789,2  
2017-04-20 10:00:03.061,2  
2017-04-20 10:00:07.247,2  
2017-04-20 10:00:07.471,2

Conf file for uploading, filtering and output

input {  
file {  
path =\> "/home/ubuntu/Logsheet3.csv"  
type =\> "sportium"  
start\_position =\> "beginning"  
}  
}  
filter {  
csv {

columns =\> ["date","responsetime"]  
separator =\> ","  
}  
date {  
match =\> ["date","YYYY-MM-dd HH:mm:ss.SSS","ISO8601"]  
target =\> "@timestamp"  
}  
mutate {  
convert =\> ["responsetime", "float"]  
}  
}  
output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "sportiumcsv"  
}  
stdout { codec =\> rubydebug }  
}

Jsonoutput in elasticsearch

"\_index": "sportiumcsv",

Why is there a trailing ",1" in the `date` field? And where's the `responsetime` field? Aha. Your `message` field is double-quoted, so the csv filter (correctly) assumes that the input contains a single column. You can use the mutate filter and its gsub option to remove the quotes, but it would be better to fix the problem at the source.

Thanks Magnus

CSV file as 2 column data- Date and responsetime which is separated by comma. I will try to correct the CSV file content to get ride of the double quotes and let you know whether it worked out.

Thanks,

Hi Magnus,

I tried below gsub mutate it didn't work, can you please guide me here.

I found the source from : [http://stackoverflow.com/questions/22534325/syntax-for-a-grok-mutate-gsub-to-replace-double-quotes-with-single-quotes/22548499#22548499](http://stackoverflow.com/questions/22534325/syntax-for-a-grok-mutate-gsub-to-replace-double-quotes-with-single-quotes/22548499#22548499)

I am not replacing with single quotes but trying to get rid of double quotes inserted by CSV

filter {  
mutate {  
gsub =\> ["message",""",""]  
}  
}

Below is full conf file data, but no luck

input {  
file {  
path =\> "/home/ubuntu/Logsheet3.csv"  
type =\> "sportium"  
start\_position =\> "beginning"  
}  
}

filter {  
csv {

columns =\> ["timestamp","responsetime"]  
separator =\> ","  
}  
mutate {  
gsub =\> ["message",""",""]  
convert =\> ["responsetime", "float"]  
}  
date {  
match =\> ["timestamp", "YYYY-MM-dd HH:mm:ss.SSS", "ISO8601"]  
target =\> "@timestamp"  
}  
}

output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "sucess-%{+YYYY.MM.dd}"  
}  
stdout { codec =\> rubydebug }  
}

Thanks,  
Manju

Try this:

```
gsub => ['message', '"', '']
```

I tried it but still had issues. So corrected at source by opening the CSV in notepad++ and removed the double quotes and saved it. then used it below code it worked perfectly!!

input {  
file {  
path =\> "/home/ubuntu/Logsheet4.csv"  
type =\> "Success"  
start\_position =\> "beginning"  
}  
}

filter {  
csv {  
columns =\> ["timestamp","responsetime"]  
separator =\> ","  
}  
mutate {  
convert =\> ["responsetime", "float"]  
}  
date {  
match =\> ["timestamp", "YYYY-MM-dd HH:mm:ss.SSS", "ISO8601"]  
target =\> "@timestamp"  
}  
}

output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "succesful-%{+YYYY.MM.dd}"  
}  
stdout { codec =\> rubydebug }  
}
