Great news!! New Metrics Support!

For a long time our community have asked for native metrics support. Despite Fluent Bit has metrics collectors for CPU, Disk I/O, Network, Memory and others the data payload was handled as a simple structured log, that is called ‘logs as metrics’. Now we are introducing ‘native metrics’. For Fluent Bit and Fluentd projects, getting into metrics is really exciting, and our vendor-neutral approach has always been to integrate to what the industry is using as a standard, so we approached Prometheus and OpenMetrics first from an integration point of view. Our new Metrics support has been a huge effort to implement several components. The initial implementation consists on: New input plugin called Node Exporter Metrics (Linux only): a small copy of the great Prometheus Node Exporter. This plugin implement a sub-set of the available metrics but respecting all the namespaces and metrics names. So you can collect your host metrics as you usually do with Prometheus Node Exporter, but this is a built-in functionality. New output plugin called Prometheus Exporter: creates an HTTP end-point to expose metrics payloads in Prometheus format, so any metric can be scraped. We developed new library CMetrics to handle all the metrics needs: counters, gauges and shortly histograms (this last one is under development).
