Side by side
A pipeline built on the Vector agent that collects, filters, redacts and routes logs to Datadog or other destinations, managed from Datadog.
A plugin-driven agent that collects metrics and logs from systems, databases, MQTT, Modbus, OPC UA and more, and writes them to InfluxDB, Prometheus and other outputs.
Ties the pipeline to Datadog's control plane and pricing.
Configuration files for many plugins get long, and defaults lean toward InfluxDB.
