| ------------------------------ | ----------- |
| `/ui/exec/:job_id/:task_group` | `text/html` |
### Parameters
- `allocation` `(string: "")` - An allocation ID that specifies which allocation to exec into.

## Optimize
~> **Enterprise Only!** This feature depends on functionality only present in Nomad Autoscaler Enterprise.
This page lists all recommendations surfaced by [dynamic application sizing](/tools/autoscaling#dynamic-application-sizing). This page will automatically redirect to the recommendation summary route for the first recommendation sorted by relevance.
Each recommendation in the list will contain information including the job and task group the recommendation is for, the time the recommendation was surfaced, the number of allocations impacted, the difference in CPU the recommendation suggests, the difference in memory the recommendation suggests, and the aggregate change in CPU and memory given the number of allocations impacted.
| Path | Produces |
| -------------- | ----------- |
| `/ui/optimize` | `text/html` |
### Parameters
- `namespace` `(string: "")` - Specifies the namespace all recommendations should be a member of. This is specified as a query string parameter.
- `all-namespaces` `(boolean: false)` - Overrides the namespace parameter and returns all recommendations for all namespaces the active ACL token is authorized for.
- `search` `(string: "")` - Specifies a regular expression used to filter the list of visible recommendations. This is specified as a query string parameter.
- `type` `(string: "")` - Filters the list of recommendations to only those for jobs with a matching type.
- `status` `(string: "")` - Filters the list of recommendations to only those for jobs with a matching status.
- `dc` `(string: "")` - Filters the list of recommendations to only those for jobs allowed in a matching datacenter value.
- `prefix` `(string: "")` - Filters the list of recommendations to only those for jobs with names that start with a matching prefix.
## Recommendation Summary
This page includes the same list of recommendations as the optimize route as well as the recommendation card for the job and task group specified in the URL. The recommendation card includes a list of all tasks for the task group as well as toggles for each recommendation available (potentially CPU and memory for each task). The card also shows before, after, and delta values for each recommendation. The before and after values are also presented in a chart that overlays the mean, p99, and max utilization values of the task a recommendation is for.
| Path | Produces |
| --------------------------------------- | ----------- |
| `/ui/optimize/:job_id/:task_group_name` | `text/html` |
### Parameters
- `namespace` `(string: "")` - Specifies the namespace of the job the recommendation is for.
## Topology Visualization
This page includes a visualization of all starting and running allocations grouped by client and by datacenter.
| Path | Produces |
| -------------- | ----------- |
| `/ui/topology` | `text/html` |
## ACL Tokens
This page lets you enter an ACL token (both accessor ID and secret ID) to use with the UI.
If the cluster does not have ACLs enabled, this page is unnecessary. If the cluster has an
anonymous policy that grants cluster-wide read access, this page is unnecessary. If the
anonymous policy only grants partial read access, then providing an ACL Token will
authenticate all future requests to allow read access to additional resources.
