# Summarize pipeline health for one or more pipelines

GET https://api.mezmo.com/v3/pipeline/health

Returns overall ingestion health as well as pipeline-specific health, such as lag in a pipeline's sources.

Reference: https://mezmo.ferndocs.com/api-reference/pipeline/pipelines/summarize-pipeline-health-for-one-or-more-pipelines

## Authentication

- `Authorization` header (required) (prefixed with ` Token  `) — Header authentication of the form `Token <token>`

## Request

### Query parameters

- `interval_minutes` (integer, optional, default: 15) — The window interval for measuring ingestion volume
- `pipeline_ids` (list of string, optional) — Return only pipelines with the given IDs

## Response

### 200

Default Response

- `meta` (map from string to any, optional)
- `data` (PipelineHealthGetResponsesContentApplicationJsonSchemaData, optional) — Overall health of data ingestion and pipeline sources

## Types

### PipelineHealthGetResponsesContentApplicationJsonSchemaData

Overall health of data ingestion and pipeline sources

- `interval_minutes` (integer, optional) — The window interval for measuring ingestion volume
- `ingestion_health` (PipelineHealthGetResponsesContentApplicationJsonSchemaDataIngestionHealth, optional)
- `pipeline_health` (PipelineHealthGetResponsesContentApplicationJsonSchemaDataPipelineHealth, optional)

### PipelineHealthGetResponsesContentApplicationJsonSchemaDataIngestionHealth

- `ingestion_metrics_status` (string, optional) — A success or failure message for the ability to fetch metrics related to ingestion routes
- `routes` (list of PipelineHealthGetResponsesContentApplicationJsonSchemaDataIngestionHealthRoutesItems, optional) — Ingestion status code health metrics per route

### PipelineHealthGetResponsesContentApplicationJsonSchemaDataPipelineHealth

- `lag_metrics_status` (string, optional) — A success or failure message for the ability to fetch lag metrics
- `pipelines` (list of PipelineHealthGetResponsesContentApplicationJsonSchemaDataPipelineHealthPipelinesItems, optional) — All active and published pipelines. Inactive or unpublished pipelines are not included.

### PipelineHealthGetResponsesContentApplicationJsonSchemaDataIngestionHealthRoutesItems

- `route` (string, optional) — The route path
- `health` (list of PipelineHealthGetResponsesContentApplicationJsonSchemaDataIngestionHealthRoutesItemsHealthItems, optional) — The health of a specific route measured by changes in status code

### PipelineHealthGetResponsesContentApplicationJsonSchemaDataPipelineHealthPipelinesItems

- `id` (string, optional) — The pipeline id
- `title` (string, optional) — The pipeline title
- `published_at` (datetime, optional) — The date/time of the pipeline's last publish (if at all)
- `sources` (list of PipelineHealthGetResponsesContentApplicationJsonSchemaDataPipelineHealthPipelinesItemsSourcesItems, optional) — Sources associated with this pipeline

### PipelineHealthGetResponsesContentApplicationJsonSchemaDataIngestionHealthRoutesItemsHealthItems

- `status_code` (integer, optional) — The HTTP status code
- `change_percent` (double, optional) — The percentage change for the status code over time. The result is a comparison of the current interval and the same interval offset by `interval_minutes` ago. For example, when `{interval_minutes: 5, offset_minutes: 5}`, that calculates the percentage change in a 5-minute window from 5 minutes ago to a 5-minute window 10 minutes ago.

### PipelineHealthGetResponsesContentApplicationJsonSchemaDataPipelineHealthPipelinesItemsSourcesItems

- `id` (string, optional) — The source id, which can also be the consumer group id
- `type` (string, optional) — The type of source component
- `title` (string, optional) — The title of the source component
- `is_consumer_group` (boolean, optional) — Whether this source is a consumer group that could have lag
- `lag_event_count` (double, optional, nullable)
