In complex environments it is useful to have a global view of all running systems. A frequently used technique is to concentrate logs in a database and to query these logs to build reports and useful metric data. the ELK suite is frequently use for this purpose. See how Convertigo can integrate with ELK and become part of a global monitoring system.
You can find all the information for integrating ELK with Convertigo here
https://github.com/convertigo/elk-kibana-logstash
You will find there all the necessary files to run an ELK stack using docker and docker-compose. Of course, if you have your own running ELK stack you can use the configuration files as samples to build your own Convertigo ELK integration.
