I have read in my Apache logfiles into Elasticsearch. They contain a field "server_name" which specifies the domain name of the site that was visited. Possible values are "domain-1.com", "domain-2.com", etc. (eight domains in all).
Here is an (anonymized) example line from the original logfiles, which specifies the site as "domain-1.com":
207.87.175.xxx - - [15/Sep/2018:00:04:49 +0800] "GET /index.html HTTP/1.1" 200 13252 www.domain-1.com "-" "Mozilla/5.0 (...)" "-"
I would like to create a graph with days on the x-axis and the number of entries for each day on the y-axis, with one line for each of my eight domains. Like this:
I've seen some tutorials on the web, this site among them, which make use of a Split Line graph that I cannot find in my version of Kibana (6.4.0).
How can I create such a graph?
I'm using Elastic Stack 6.4.0
