While searching for an elasticsearch tail -f, I stumble upon this nice piece of software that does exactly that. Reading the configuration file I noticed the server_kibana-proxy section and wondered if that meant that elasticsearch could be queried via kibana, and it turns out that yes, you don’t have to expose ES port (:9200), you can use kibana’s API instead, in particular the console API to be able to query ES directly.
Here’s a procedure I came up with in order to migrate an elasticsearch 1.1 database to version 6 (actually 6.4 but probably any 6.x version).
Fetch the tar.gz version from https://www.elastic.co/downloads/past-releases/filebeat-1-1-2 and untar it.
Use the following basic configuration file
$ egrep -v '^[[:space:]]*(#|$)' ~/tmp/elasticsearch-1.1.2/config/elasticsearch.yml
http.port: 9202
transport.tcp.port: 9302
path.conf: /home/imil/tmp/elasticsearch-1.1.2/config
path.data: /var/db/elasticsearch
Note that I changed the standard ports to $((standard_port + 2)).
From the untarred directory, lauch elasticsearch
