Loggregator Agent
Loggregator Agent is a Cloud Foundry component that forwards logs and metrics into the Loggregator subsystem by taking traffic from the various emitter sources (diego, router, etc) and routing that traffic to one or more dopplers. An instance of Loggregator Agent runs on each VM in an environment and is therefore co-located on the emitter sources.
Traffic is routed to Dopplers in the same AZ, but it can fall back to any Doppler if none are available in the current AZ. All Loggregator Agent traffic is randomly distributed across available Dopplers.
Loggregator Agent only listens to local network interfaces and all logs and metrics are immediately signed before forwarding to Dopplers. This prevents man-in-the-middle attacks and ensures data integrity.
Compatibility
The Loggregator Agent is compatable with Loggregator v96+.
Using Loggregator Agent
go-loggregator
There is Go client library: [go-loggregator][go-loggregator]. The client library has several useful patterns along with examples to interact with a Loggregator Agent.
