title: Monitor Docker Trusted Registry
|
|
---
|
|
|
|
Docker Trusted Registry is a Dockerized application. To monitor it, you can
|
|
use the same tools and techniques you're already using to monitor other
|
|
containerized applications running on your cluster. One way to monitor
|
|
DTR is using the monitoring capabilities of Docker Universal Control Plane.
|
|
|
|
In your browser, log in to **Docker Universal Control Plane** (UCP), and
|
|
navigate to the **Applications** page.
|
|
|
|
To make it easier to find DTR, use the search box to **search for the
|
|
DTR application**. If you have DTR set up for high-availability, then all the
|
|
DTR nodes are displayed.
|
|
|
|
|
|
|
|
**Click on the DTR application** to see all of its containers, and if they're
|
|
running. **Click on a container** to see its details, like configurations,
|
|
resources, and logs.

## Health checks
|
|
|
|
DTR also exposes several endpoints you can use to assess if a DTR replica
|
|
is healthy or not:
|
|
|
|
* `/health`: Checks if the several components of a DTR replica are healthy, and
|
|
returns a simple json response. This is useful for load balancing or other
|
|
automated health check tasks.
|
|
* `/load_balancer_status`: Checks if the several components of a DTR replica
|
|
can be reached, and displays that information in a table. This is useful for
|
|
an administrator to gauge the status of a DTR replica.
|
|
* `/nginx_status`: Returns the number of connections being handled by the
|
|
NGINX front-end used by DTR.
|
|
* `/api/v0/meta/cluster_status`: Returns extensive information about all DTR
|
|
replicas.
