Logstash split String


(Thomas) #1

Hallo all togehter,

i have build a new instance with icinga-beat->logstash->elasticsearch->kibana (all with the newest version)

Everything works fine, but i have a litte problem with split one string to an array.

The variable in want to split is "check_result.output" and an sample Output in Kibana would be "c:\ - total: 59.66 Gb - used: 47.92 Gb (80%) - free 11.73 Gb (20%) ". So now i want to split these string to an array (seperator should be "-")

I build up a new logstash.conf file with this filter:

filter {
mutate{
split => ["check_result.output", "-"]
add_field => {
"event" => "%{check_result.output[0]}"
"eventSource" => "%{check_result.output[2]}"
}
}

The new fileds get generated in the Kibana Dashboard, but the values from the array are not visible, it just shows: %{check_result.output[0]}

The syntax for how the reference nested fields is described here: https://www.elastic.co/guide/en/logstash/current/event-dependent-configuration.html#logstash-config-field-references
