Import cbt results to ELK

Creates ELK cluster and watches for LOGSTASH_DIR directory (see .env file).

So far parses only cbt results.

• setup docker, and docker-compose
• check that your system has correct parameters for elk in docker sysctl -w vm.max_map_count=262144
• clone this repo, cd elk_cbt
• docker-compose up -d
• name convention for cbt results directory (see pipeline/general.conf) - branch_tag_cluster_result_desc:
  • branch - name of the branch (jewel, luminous or product ses5)
  • tag - tag name or milestome name
  • cluster - stable cluster config name - so you could identify what cluster you used for this test
  • result_desc - additional info about test - maybe some additional parameters that aren't tracked in fio results
• create directories rados and librbd under LOGSTASH_DIR
• copy your cbt results directory to LOGSTASH_DIR/rados or to LOGSTASH_DIR/librbd
• be aware - logstash will delete all imported json files
• go to Kibana interface in web browser http://your_host:5601 (usually localhost)
• don't forget to change Time Filter in the right corner to something more sane (defaults to 15 Min) - maybe to "Year to date"
• use filters, searches and Time Range to filter and look for you data
• docker-compose down to stop containers
• elasticsearch data would be stored in docker volume
