OS : Centos 7.4, ELK Version: 7.6.2
I am trying to count how many hosts are configured in the ELK stack and for some reason beat.hostname.keyword
is not pulling any data.
If i use the default metric without any other filter, i see the count ( about 10000 )
Also, i see the the index has a field agent.hostname
however i am not seeing it in kibana filters / terms.
Any suggestions how i can use the agent.hostname
field to count the hosts ?
