HI Team ,
i'm using metrics filter plugin for different files with their respective count. but i'm unable to get the metrics results.
here is my logstash conf
input{
**reading log file here**
}
filter{
\*\*using grok to extract file\_name \*\*
metrics {
meter =\> ["%{file\_name}"]
add\_tag =\> "metrics"
id =\> "file\_count"
}
}
output {
if "metrics" in [tags] {
stdout {
codec =\> line {
format =\> " %{file\_name} --\> COUNT : %{[file\_name][count]}"
}
}
}
OUTPUT i'm getting is
%{file\_name} --\>COUNT : %{[file\_name][count]}
%{file\_name} --\>COUNT : %{[file\_name][count]}
%{file\_name} --\>COUNT : %{[file\_name][count]}
Expected output
file1--\> COUNT:100
file2--\> COUNT:100
file3--\> COUNT:100
could you please help here?
