What are Log Collectors (Aggregators)?

Data System Architecture


A log collector will collect log file, optionally transform them and deliver them to one or more destination such as:


Name Type Log to Log Log To Metrics Description
Vector (Rust, DataDog) observability pipeline tool Yes Yes
Telegraph (Go, InfluxDb)
Promtail (Graphana) Log Collector Yes Yes 1) Graphana tool to insert log Loki
Logstash (Java, Elastic) Log Collector Yes Yes 2) Elastic log collector
FluentBit Log Collector ? ? Successor to FluentD
Fluentd Log Collector ? ? Example: BigQuery
Flume Log Collector ? ?

Log to Metrics means extracting metrics from application logs to be exported into a metrics server
