Sporadic "An unexpected error occurred" while starting up logstash #77
Description
I am facing a, possible, issue with logstash 1.2.1. Sporadically, when starting it up, I receive the following error:
java -jar logstash-1.2.1-flatjar.jar agent -f conf/logstash.conf -- web

Using milestone 2 input plugin 'file'. This plugin should be stable, but if you see strange behavior, please let us know! For more information on plugin milestones, see http://logstash.net/docs/1.2.1/plugin-milestones {:level=>:warn}

The error reported is:
pattern %{GREEDYDATA:message_id} not defined
My configuration file looks like this:
input {
file {
type => "my-component"
path => [ "/path/to/my/log/directory/*.log" ]
add_field => [ "API", "mycomponent"]
}
...
}
filter {
if [type] == "my-component" {
grok {
match => [ "message", "(%{GREEDYDATA:message_id}) %{TIMESTAMP_ISO8601:log_timestamp} %{LOGLEVEL:loglevel} %{GREEDYDATA:message_remainder}" ]
add_field => ["raw_message", "%{@message}"]
}
mutate {
replace => ["message", "%{message_remainder}" ]
}
multiline {
pattern => "^\s"
what => "previous"
}
}
}
output {
elasticsearch { embedded => true }
}
It works if I kill it and start it again.
