Using conditionals to decide which logs to filter

Hi, I'm using the beat utilities to ship logs to Logstash. I only want to parse the logs using the grok filter when it's coming from filebeat, but I can't seem to get it to work. The parsing works the way I want it to, but when I add the conditional, it doesn't go through.

Here's what my filter section looks like:

filter {
  if [input.type] == "log" {
    grok {
      match => { "message" => "%{TIMESTAMP_ISO8601:ltm.timestamp}\s%{}\s%{LOGLEVEL:log.level}\s%{PROG:program}(?:\[%{POSINT:pid}\])?:\s%{GREEDYDATA:ltm.message}" }
    date {
      match => [ "time", "ISO8601" ]

Any insight on how to use the conditional correctly would be greatly appreciated! Thanks!

[input.type] refers to a field with a period in the name. You probably want the type field within the input object, which would be [input][type]

Works now! Thanks!
