Hi Team,
I have basic ELK use case wherein I am consuming syslog data from client through Logstash, storing in ES & visualize in Kibana.
In addition to this, In Syslog incoming data I have IP address field, but I don’t have hostname of respective IP address. Now my requirement is I want to consume this respective Hostname of given IP address from my Oracle DB table. I have a ‘Device’ table in my DB which has ‘IP Address’ & ‘Hostname’ field. Which is the correct way to consume this info & how?
-
Is there any Logstash or Elastic search plugin which can make query to DB in runtime to get this hostname info? If so, will there be any DB performance issue as I may have many such request in production environment.
-
Should we write some script to get ‘Device’ table info from DB & store in some CSV file(some folder/filepath) then make query from Logstash/ES to get this hostname info ?
Thanks
