# Observability
|
|
|
|
In order to take advantage of Connect's L7 observability features you will need
|
|
to:
|
|
|
|
- Deploy sidecar proxies that are capable of emitting metrics with each of your
|
|
services. We have first class support for Envoy.
|
|
- Define where your proxies should send metrics that they collect.
|
|
- Define the protocols for each of your services.
|
|
- Define the upstreams for each of your services.
|
|
|
|
If you are using Envoy as your sidecar proxy, you will need to [enable
|
|
gRPC](/docs/agent/options.html#grpc_port) on your client agents. To define the
|
|
metrics destination and service protocol you may want to enable [configuration
|
|
entries](/docs/agent/options.html#config_entries) and [centralized service
|
|
configuration](/docs/agent/options.html#enable_central_service_config).
|
|
|
|
If you
|
|
are using Kubernetes, the Helm chart can simplify much of the necessary
|
|
configuration, which you can learn about in the [observability
|
|
guide](https://learn.hashicorp.com/consul/getting-started-k8s/l7-observability-k8s).
|
|
|
|
### Metrics Destination
|
|
|
|
For Envoy the metrics destination can be configured in the proxy configuration
|
|
entry's `config` section.
|
|
|
|
```
|
|
kind = "proxy-defaults"
|
|
name = "global"
|
|
config {
|
|
"envoy_dogstatsd_url": "udp://127.0.0.1:9125"
|
|
}
|
|
```
|
|
|
|
Find other possible metrics syncs in the [Connect Envoy documentation](/docs/connect/proxies/envoy.html#bootstrap-configuration).
|
|
|
|
### Service Protocol
|
|
|
|
You can specify the [service protocol](/docs/agent/config-entries/service-defaults.html#protocol)
|
|
in the `service-defaults` configuration entry. You can override it in the
|
|
[service registration](/docs/agent/services.html). By default, proxies only give
|
|
you L4 metrics. This protocol allows proxies to handle requests at the right L7
|
|
protocol and emit richer L7 metrics. It also allows proxies to make per-request
|
|
load balancing and routing decisions.
|
|
|
|
### Service Upstreams
|
|
|
|
You can set the upstream for each service using the proxy's
|
|
[`upstreams`](/docs/connect/registration/service-registration.html#upstreams)
|
|
sidecar parameter, which can be defined in a service's [sidecar
|
|
registration](/docs/connect/registration/sidecar-service.html).
