Fluentd is written in Ruby for flexibility, with performance-sensitive parts in C. However, some users may have difficulty installing and operating a Ruby daemon.
That is why Fluentd Project provides the stable distribution of Fluentd, called fluent-package (formerly known as td-agent). The differences between Fluentd and fluent-package can be found here.
This article explains the difference between fluent-package v5 and td-agent v4.
{% hint style='danger' %} The series of td-agent had already reached End of Life (EOL). td-agent should not be newly installed because of no support, no new release and no security updates anymore. Use fluent-package instead! {% endhint %}
