  • Very confused with using fluentd to filter out PII sent to cloudwatch.
    Lastly, I know the question was around Fluentd - however if you are looking for super high performance I also recommend taking a look at Fluent Bit (https://fluentbit.io) it's more performant sub-project. Simliar functionality with grep (https://docs.fluentbit.io/manual/pipeline/filters/grep) exists, and there are examples of using the in-built LUA scripting for more processing type filtering (https://github.com/couchbase/couchbase-fluent-bit#redaction)
  • Four months since my last post, I finally finished my series on self-hosted monitoring including config files and example configurations - sorry it took so long!
    Missing from you fluentbit setup - you need to add the parser "iptables" into parser.conf, which you can find in https://github.com/fluent/fluent-bit/blob/master/conf/parsers_extra.conf
    Yikes, considering that I wrote that parser, I probably should have remembered to include it!
  • Fluentd use case in Kubernetes ... Help
  • Containers for log collection across multiple servers and tools?

    As far as understand your question, have tried fluentbit yet? It's an open-source log processor and forwarder.
  • So, I'm new here, what do you all use your servers for?

    Fluentd.org and fluentbit.io are responsible for collecting all and any logs and passing them to https://grafana.com/oss/loki/ which stores the log messages for future searching.

    The first link in this article is about switching from fluentbit to fluentd.

    Me too. I have issue with fluenbit. Especially around their JSON processing. As in this issue: https://github.com/fluent/fluent-bit/issues/1588

    If you want a simple log forwarding, fluentbit is really good. But if you found yourself started to tweak fluentbit config, or write custom plugin in C and (recompile yourself) then it's time to move to fluentd.
