No longer seeing nginx log indexes after ILM deployed

[maxhyjal]

Hey all, after I set up the index lifecycle management system in ELK stack, I can no longer see the nginx indexes generated in Kibana, can anyone point out what I might have done wrong?

My setting on filebeat:

setup.ilm.enabled: auto
setup.ilm.rollover_alias: "webaccess"
setup.ilm.pattern: "{now/d}-000001"
setup.ilm.policy_name: "mylogs_policy"

fields:
source_log: web_access
index_prefix: web_access
app: all

configs on elasticsearch:

    {
      "indices" : {
      "web_access-000001" : {
      "index" : "web_access-000001",
