Hi,

I am using multiple files as input, where type =\> csv is for loading csv file into elatsicsearch and type =\> syslog is for tracking the exception.

My config looks like below:

input  
{  
file {  
path =\> "path-to-csv-file/\*.csv"  
type =\> "csv"  
start\_position =\> beginning  
}  
file {  
path =\> "path-to-log-file/logstash-plain.log"  
type =\> "syslog"  
sincedb\_path =\> "null"  
}  
}  
filter  
{  
if [type] == "csv"  
{  
csv  
{  
columns =\> [............................]  
separator =\> ","  
}  
mutate  
{  
remove\_field =\> ["message","path","host","type"]  
}  
}  
if [type] == "syslog"  
{ .......................}  
}  
output  
{  
if [type] == "csv"  
{  
elasticsearch  
{ ................ }  
}  
if [type] == "syslog"  
{ .................}  
stdout{}  
}

Any ideas how can I make it work.

Thank you.
