Loki with filebeat metricbeat

hello
simple question? do I need to use promtail or I can use filebeat metricbeat or others?
what are the advantages of using promtail?

Hello @dtskitishvili,

as far as I know, Elastic Beats agents do not support output to Loki. Maybe there are some community outputs for them…

You can use Promtail/Grafana Agent, Fluentd, Fluent-bit, etc. There is also some sort of Logstash output plugin for Loki.
