- Difficult to monitor and debug Fluentd internal issues (ex. out of bufffer).

You'll need DataDog [2] or using Prometheus to collect fluentd metrics.

- Even there are high availability configurations [3],

it still needs extra design to ensure service availability.

I have used Fluentd on real-time distributed logging machines hosted on cloud to gather raw logs, filter logs, parse raw logs to well-formed JSON, forward all well-formed JSON logs to central fluentd machine (with backup node) central fluentd machine acts as an intermediate node which further forwards logs to the elastic search cluster master node. I had configured Kibanna and Elast alerts on master elastic search node to view and get real time business alerts. Review collected by and hosted on G2.com.

Performance is little show - each Fluentd instance can only process around 18,000 events per second.

We can enable multi-process workers to increase throughput, but this may cause problems with plugins that don’t support this feature. Review collected by and hosted on G2.com.

Fluentd is light weight process and when you are setting up an cluster of k8s, it's best to use and logging agent which has less overhead for resources.

There is no dislike but as an improvement suggestion, similar to Prometheus , it should be have capability to collect windows events or application metrics so that with less service one stop solution can be used. Review collected by and hosted on G2.com.

using fluentd, one can easily ship host or container logs to multiple configurable destinations pretty quickly and with so many customization options available before sending them, it makes it much more powerful Review collected by and hosted on G2.com.

its a bit bulky on the memory and cpu side Review collected by and hosted on G2.com.
