Doesn't work when trying to match on "source" and "message" in the same grok

Good day everyone!

I'm using filebeat and logstash.

Here is the part of logstash filter which is not working as I'm expecting.

if "app_name" in [tags] {

mutate {
    gsub => ["message", "\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]", ""]

  grok {
     match => [
                "source" => "/opt/data/app/logs/%{GREEDYDATA:service_name}/%{GREEDYDATA:log_file_name}",
                "message" => "\[%{GREEDYDATA:severity}\] %{TIMESTAMP_ISO8601:timestamp} - %{GREEDYDATA:message}"
       overwrite => [ "message" ]

  date {
    match => [ "timestamp", "yyyy-mm-dd HH:mm:ss" ]
    target => "@timestamp"
    timezone => "UTC"
    remove_field => ["timestamp"]

As you can see, I'm trying to match and extract values from "source" field and "message" field in the same grok. But works only the first one (in this example - "source").

Is there a way how to achieve that?

Any help will be extremely appreciated!

By default, Grok stop after the first match successful, which mean that if first parsing is successful (source), message parsing will not be 'invoqued'.

To allow it to match your multiple fields / formats, you will need to disable the option break_on_match
