I can't see the tags of my own patterns

hello,

i have written my own patterns file with plenty of tags but i can't see the tags in Kibana?

for example:

RVS_FINEST %{RVS_BASE}, (%{RVS_MESSAGE_RECEIVED:log_message}|%{RVS_MESSAGE_RECEIVED2:log_message}|%{RVS_MESSAGE_RECEIVED3:log_message}|%{GREEDYDATA:log_message})

but i can't see the tags...

could you please reply ? thanks in advance

best regards,
Alok

How do you know they work in Logstash?
