Returns information related to the current state of the detector and memory usage, including current errors and shingle size, to help troubleshoot the detector. This command helps locate logs by identifying the nodes that run the anomaly detector job for each detector. It also helps track the initialization percentage, the required shingles, and the estimated time left. #### Request ```json GET _plugins/_anomaly_detection/detectors//_profile/ GET _plugins/_anomaly_detection/detectors//_profile?_all=true GET _plugins/_anomaly_detection/detectors//_profile/ GET /_plugins/_anomaly_detection/detectors//_profile/, ``` #### Sample Responses ```json GET _plugins/_anomaly_detection/detectors//_profile { "state":"DISABLED", "error":"Stopped detector: AD models memory usage exceeds our limit." } GET _plugins/_anomaly_detection/detectors//_profile?_all=true&pretty { "state": "RUNNING", "models": [ { "model_id": "cneh7HEBHPICjJIdXdrR_model_rcf_2", "model_size_in_bytes": 4456448, "node_id": "VS29z70PSzOdHiEw4SoV9Q" }, { "model_id": "cneh7HEBHPICjJIdXdrR_model_rcf_1", "model_size_in_bytes": 4456448, "node_id": "VS29z70PSzOdHiEw4SoV9Q" }, { "model_id": "cneh7HEBHPICjJIdXdrR_model_threshold", "node_id": "Og23iUroTdKrkwS-y89zLw" }, { "model_id": "cneh7HEBHPICjJIdXdrR_model_rcf_0", "model_size_in_bytes": 4456448, "node_id": "Og23iUroTdKrkwS-y89zLw" } ], "shingle_size": 8, "coordinating_node": "Og23iUroTdKrkwS-y89zLw", "total_size_in_bytes": 13369344, "init_progress": { "percentage": "70%", "estimated_minutes_left": 77, "needed_shingles": 77 } } GET _plugins/_anomaly_detection/detectors//_profile/total_size_in_bytes { "total_size_in_bytes" : 13369344 } ``` If you configured the category field, you can see the number of unique values in the field and all active entities with models running in memory.
