# Compute an SLO instance summary at a point in time

`GET /s/{spaceId}/api/observability/slos/{sloId}/_snapshot`

Compute the summary of an SLO at a given point in time. When `instanceId` is provided, returns that instance. When `instanceId` is omitted or set to `'*'`, returns all matching instances (up to 1000). The endpoint is synchronous and returns results directly. You must have the `read` privileges for the **SLOs** feature in the **Observability** section of the Kibana feature privileges.

## Path parameters

- `spaceId` string, required
- `sloId` string, required

## Query parameters

- `at` string, date-time, required
- `instanceId` string

## Headers

- `kbn-xsrf` string, required

## Response `200`

Successful response

- SLOsSnapshotResponse — The snapshot SLO response returns the point in time and the per-instance results. Each result contains either a summary (success) or an error (per-instance failure).
  - `at` string, date-time, required — The point in time at which the summaries were computed
  - `results` SLOsSnapshotResult[], required — The per-instance computation results
    - `error` object — Error information when the computation failed for this SLO instance. Present when the computation failed.
      - `message` string, required — The error message
      - `statusCode` number, required — The HTTP status code of the error
    - `id` string, required — The SLO definition id
    - `instanceId` string, required — The SLO instance id. '*' represents the default (ungrouped) instance.
    - `summary` object — The SLO instance summary at the requested point in time. Present when the computation succeeded.
      - `errorBudget` object, required
        - `consumed` number, nullable, required — The error budget consumed, or null when no data is available
        - `initial` number, required — The initial error budget, derived from the SLO objective
        - `remaining` number, nullable, required — The error budget remaining, or null when no data is available
      - `good` number, required — The number of good events
      - `sliValue` number, nullable, required — The SLI value at the requested point in time, or null when no data is available
      - `status` 'NO_DATA' | 'HEALTHY' | 'DEGRADING' | 'VIOLATED', required — The SLO health status
      - `total` number, required — The total number of events
