elasticsearch Logstash translate筛选器不添加任何字段

我最近安装了添加到我的netflow筛选器1 translate

---

========================================================================

Logstash说ConfigOK，但我在discover kibana中没有看到任何内容，也没有在映射索引中看到任何新内容

有什么想法吗

    if [netflow][src_addr] {
        translate {
            id => "netflow-translate-suscriberid"
            dictionary_path => "${ANALYTICS_DICT_PATH:/etc/logstash/analytics/dictionaries}/suscriberid-ip.yaml"
            field => "[netflow][src_addr]"
                destination => "[subscriberDeviceID]"
                refresh_interval=> 30
            fallback => "not_found"
        }
}
