This is a BOSH-release add-on for Logsearch tool. It extends base ELK stack, which provides Logsearch, to work with CloudFoundry logs.
So, If you have CloudFoundry deployment and want to make logs management with ELK stack then you choose right product to use. Out-of-the box you’ll get retrieving and parsing logs from your CloudFoundry platform, authorized access to these logs in Kibana and useful dashboards and search queries to start your log analysis with.
