Metrics
Dapr exposes a Prometheus metrics endpoint that you can scrape to gain a greater understanding of how Dapr is behaving and to setup alerts for specific conditions.
Configuration
The metrics endpoint is enabled by default, you can disable it by passing the command line argument
--enable-metrics=false to daprd.
The default metrics port is 9090. This can be overridden by passing the command line argument
--metrics-port to darpd.
Metrics
Dapr will expose metrics for Darp's HTTP pipeline, gPRC pipeline, Go runtime, metrics server and process.
Note: The gRPC metrics are all initialized with zero values and are therefore immediately visible on the metrics endpoint. HTTP metrics are not zero initialized so will only become visible once a HTTP request has passed through the HTTP pipeline.
Prometheus
To consume these metrics you'll need to install Prometheus or something compatible with scraping Prometheus metrics.
For more detailed instructions on installing and configuring Prometheus to work with Dapr, please refer to the Observe Metrics with Prometheus article.
