Profile detector
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.

If you have configured the category field, you can see the number of unique values in the field and also all the active entities with models running in memory. You can use this data to estimate the memory required for anomaly detection to help decide the size of your cluster. For example, if a detector has one million entities and only 10 of them are active in memory, then you need to scale up or scale out your cluster.

The profile operation also provides information about each entity, such as the entity’s last_sample_timestamp and last_active_timestamp.
No anomaly results for an entity indicates that either the entity doesn't have any sample data or its model is removed from the model cache.
last_sample_timestamp shows the last document in the input data source index containing the entity, while last_active_timestamp shows the timestamp when the entity’s model was last seen in the model cache.
