Conditional Output Not Working


(Bjmaynard01) #1

I have come across an interesting problem that is causing me to bash my head against the wall. I'm trying to parse nginx access logs and eventually dump them into ES. However, for testing purposes, I am using stdout. in the below config, when I remove the conditional for [id] I get output to stdout as expected. But when I configure it with a conditional, as will be needed for indexing, no output is generated.

The input is:

input {
syslog {
port => 2359
id => "cookbook_access"
type => "nginx_access"
host => "XXX.XXX.XXX.XXX"
timezone => "American/New_York"
}
}

Now, when I use this as the output, I get output generated, as expected.

stdout {
codec => rubydebug
}

However, when I change the output to be

if [id] == "cookbook_access" {
stdout {
codec => rubydebug
}
}

No output is generated.

The id option adds an identifier to the plugin. It won't attach an id field to each event processed by the input. You should probably be using the type or the add_field option instead.
