Resource: ModelMonitor
Vertex AI Model Monitoring service serves as a central hub for the analysis and visualization of data quality and performance related to models. ModelMonitor stands as a top level resource for overseeing your model monitoring tasks.
name 
 
  string 
 
Immutable. Resource name of the ModelMonitor. Format: projects/{project}/locations/{location}/modelMonitors/{modelMonitor} 
.
displayName 
 
  string 
 
The display name of the ModelMonitor. The name can be up to 128 characters long and can consist of any UTF-8.
modelMonitoringTarget 
 
  object (  ModelMonitoringTarget 
 
) 
 
The entity that is subject to analysis. Currently only models in Vertex AI Model Registry are supported. If you want to analyze the model which is outside the Vertex AI, you could register a model in Vertex AI Model Registry using just a display name.
trainingDataset 
 
  object (  ModelMonitoringInput 
 
) 
 
Optional training dataset used to train the model. It can serve as a reference dataset to identify changes in production.
notificationSpec 
 
  object (  ModelMonitoringNotificationSpec 
 
) 
 
Optional default notification spec, it can be overridden in the ModelMonitoringJob notification spec.
outputSpec 
 
  object (  ModelMonitoringOutputSpec 
 
) 
 
Optional default monitoring metrics/logs export spec, it can be overridden in the ModelMonitoringJob output spec. If not specified, a default Google Cloud Storage bucket will be created under your project.
explanationSpec 
 
  object (  ExplanationSpec 
 
) 
 
Optional model explanation spec. It is used for feature attribution monitoring.
modelMonitoringSchema 
 
  object (  ModelMonitoringSchema 
 
) 
 
Monitoring Schema is to specify the model's features, prediction outputs and ground truth properties. It is used to extract pertinent data from the dataset and to process features based on their properties. Make sure that the schema aligns with your dataset, if it does not, we will be unable to extract data from the dataset. It is required for most models, but optional for Vertex AI AutoML Tables unless the schem information is not available.
encryptionSpec 
 
  object (  EncryptionSpec 
 
) 
 
Customer-managed encryption key spec for a ModelMonitor. If set, this ModelMonitor and all sub-resources of this ModelMonitor will be secured by this key.
createTime 
 
  string (  Timestamp 
 
format) 
 
Output only. timestamp when this ModelMonitor was created.
Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" 
, "2014-10-02T15:01:23.045123456Z" 
or "2014-10-02T15:01:23+05:30" 
.
updateTime 
 
  string (  Timestamp 
 
format) 
 
Output only. timestamp when this ModelMonitor was updated most recently.
Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" 
, "2014-10-02T15:01:23.045123456Z" 
or "2014-10-02T15:01:23+05:30" 
.
satisfiesPzs 
 
  boolean 
 
Output only. reserved for future use.
satisfiesPzi 
 
  boolean 
 
Output only. reserved for future use.
default_objective 
 
  Union type 
 
 default_objective 
can be only one of the following:tabularObjective 
 
  object (  TabularObjective 
 
) 
 
Optional default tabular model monitoring objective.

ModelMonitoringTarget
The monitoring target refers to the entity that is subject to analysis. e.g. Vertex AI Model version.
source 
 
  Union type 
 
 source 
can be only one of the following:vertexModel 
 
  object (  VertexModelSource 
 
) 
 
Model in Vertex AI Model Registry.

VertexModelSource
Model in Vertex AI Model Registry.
model 
 
  string 
 
Model resource name. Format: projects/{project}/locations/{location}/models/{model}.
modelVersionId 
 
  string 
 
Model version id.

| { "model" : string , "modelVersionId" : string } | 
ModelMonitoringSchema
The Model Monitoring Schema definition.
featureFields[] 
 
  object (  FieldSchema 
 
) 
 
feature names of the model. Vertex AI will try to match the features from your dataset as follows:  * For 'csv' files, the header names are required, and we will extract the  corresponding feature values when the header names align with the  feature names.  * For 'jsonl' files, we will extract the corresponding feature values if  the key names match the feature names.  Note: Nested features are not supported, so please ensure your features  are flattened. Ensure the feature values are scalar or an array of  scalars.  * For 'bigquery' dataset, we will extract the corresponding feature values  if the column names match the feature names.  Note: The column type can be a scalar or an array of scalars. STRUCT or  JSON types are not supported. You may use SQL queries to select or  aggregate the relevant features from your original table. However,  ensure that the 'schema' of the query results meets our requirements.  * For the Vertex AI Endpoint Request Response Logging table or Vertex AI  Batch Prediction Job results. If the instanceType 
is an array,  ensure that the sequence in  featureFields 
 
matches the order of  features in the prediction instance. We will match the feature with the  array in the order specified in [featureFields].
predictionFields[] 
 
  object (  FieldSchema 
 
) 
 
Prediction output names of the model. The requirements are the same as the  featureFields 
 
. For AutoML Tables, the prediction output name presented in schema will be: predicted_{targetColumn} 
, the targetColumn 
is the one you specified when you train the model. For Prediction output drift analysis:  * AutoML Classification, the distribution of the argmax label will be  analyzed.  * AutoML Regression, the distribution of the value will be analyzed.
groundTruthFields[] 
 
  object (  FieldSchema 
 
) 
 
Target /ground truth names of the model.
