Monitoring

Using the middleware pattern KnightBus can monitor message processing with any tool you’d like.

Already available monitoring middlewares

• New Relic
• Application Insights

New Relic

Install the package KnightBus.NewRelic and configure KnightBusHost to use New Relic.

var knightBus = new KnightBusHost()
    .UseTransport(...)
    .Configure(configuration => configuration
        .UseNewRelic()
        ...
    );

Liveness

TcpAliveListenerPlugin offers monitoring for liveness using TCP that can be used for services that don’t serve http.

var knightBus = new KnightBusHost()
    .UseTransport(...)
    .Configure(configuration => configuration
        .UseTcpAliveListener(port: 13000)
        ...
    );

Example using Kubernetes:

livenessProbe:
 tcpSocket:
  port: {{  .Values.ports.liveness  }}
 initialDelaySeconds: 10
 periodSeconds: 10
 timeoutSeconds: 3
 successThreshold: 1
 failureThreshold: 5

See https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#define-a-tcp-liveness-probe for more information on how to configure liveness with tcp.
