Filters narrow by queue system, destination, service or any span attribute. ## Request 14 fields, body `application/json` (required). | Field | In | Type | Required | Description | | ------------------------------ | ---- | --------------------------- | -------- | --------------------------------------------------------------------- | | `end` | body | integer (int64) | — | End is the window's end, epoch nanoseconds. | | `filters` | body | o11y.O11yQueueFilterSet | — | | | `filters.items` | body | o11y.O11yQueueFilterRule\[] | — | Items are the predicates. | | `filters.items[].key` | body | o11y.O11yQueueFilterKey | — | | | `filters.items[].key.dataType` | body | string | — | DataType is the attribute's type: string, int64, float64 or bool. | | `filters.items[].key.isColumn` | body | boolean | — | IsColumn marks an attribute materialized as its own store column. | | `filters.items[].key.isJSON` | body | boolean | — | IsJSON marks an attribute read out of the span's JSON body. | | `filters.items[].key.key` | body | string | — | Key is the attribute name. | | `filters.items[].key.type` | body | string | — | Type says which plane the attribute lives on: tag or resource. | | `filters.items[].op` | body | string | — | Op is the comparison, e.g. =, !=, in, contains. | | `filters.items[].value` | body | any | — | Value is the operand; its JSON type follows the attribute's dataType. | | `filters.op` | body | string | — | Op combines the items: AND or OR. | | `limit` | body | integer (int64) | — | Limit caps how many rows come back. | | `start` | body | integer (int64) | — | Start is the window's start, epoch nanoseconds. | ## Response | Status | Body | Meaning | | --------- | --------------------- | ----------------- | | `200` | o11y.O11yQueueRowsOut | ok | | `202` | Approval | held for approval | | `default` | problem-details | refused | `200` body — 5 fields. | Field | In | Type | Always | Description | | ------------------ | ---- | -------------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------- | | `data` | body | o11y.O11yQueueRow\[] | — | Data holds one row per messaging destination. | | `data[].data` | body | object | — | Data holds the row's cells keyed by column name; each cell's JSON type is the column's own, so the bytes pass through verbatim. | | `data[].data.*` | body | any | — | | | `data[].timestamp` | body | string (date-time) | — | Timestamp anchors the row in time. | | `status` | body | string | — | Status is "success". | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo o11y messaging-queues queue-overview ``` **SDK** **.ts** ```ts import { Configuration, O11yApi } from 'hanzoai'; const api = new O11yApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.postO11yMessaging-queuesQueue-overview({ end: 0, filters: {"items":[{"key":{"dataType":null,"isColumn":null,"isJSON":null,"key":null},"op":"","value":""}],"op":""} }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import O11yApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = O11yApi(client).post_o11y_messaging-queues_queue-overview(end=0, filters={"items":[{"key":{"dataType":null,"isColumn":null,"isJSON":null,"key":null},"op":"","value":""}],"op":""}) ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.O11yAPI.PostO11yMessaging-queuesQueue-overview(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, o11y_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = o11y_api::post_o11y_messaging-queues_queue-overview(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.O11yApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new O11yApi(client).postO11yMessaging-queuesQueue-overview(); ``` The method above is the one at the current release of the document. `hanzoai@8.5.914` (npm) and `hanzoai@8.5.914` (PyPI) were generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree.
