  Netmore

  Mar 2018 - Jun 2018

  Software designer/data engineer

  Project: System monitoring based on Elastic SearchIntegrated ELK stack to monitor Linux Clusters and daily log files. Developed a Ruby plugin to ELK stack to send instant alarms automatically. In order to do this I designed and developed a self-contained system without external scheduling like Cron, data was pulled from Elasticsearch to Logstash in addition to the typical push of events from Logstash to Elasticsearch. This was done by a filter that executes Ruby code in the Logstash event processing. As Logstash may process a very number of events in parallel, and run on a cluster, this required some care to get good performance and thread safety. (The employment was terminated due to the company’s financial problem, but they were very satisfied with my work and wrote me good reference. Om deras ekonomisk situation ändras och de behöver min kompetens, har de sagt att de skall kontakta mig först.) Show less
