Logstash Create and Access Array

问题:

I want to create an array in the logstash config file that is for devices and then access the array value by for a new field that I am creating. example:

filter {
     array_devicetype => ["Cisco ASA", "Cisco 3750"]
     mutate {
            add_field => { "Device Type" => "%{array_devicetype[0]}"
     }
}

Yet, no luck. Can someone help me out with this? Thanks.

If there is no any filter plugin can help you, you can try to use ruby and then do it yourself. For example

filter {
    ruby {
            code => "
                    event['array_devicetype'] = ['Cisco ASA', 'Cisco 3750']
                    event['Device Type'] = event['array_devicetype'][0]
            "
    }
}

Use this filter can do what you want. FYI.
