View replica logs for a model using the CLI

When a model is deployed, CDSW enables you to specify the number of replicas that must be deployed to serve requests. If a replica crashes or fails to come up, you can diagnose it by viewing the logs for every replica using the model CLI.

Obtain the modelReplicaId by using the following command:
```
cdswctl models listReplicas --modelDeploymentId=<model_deployment_ID>
```
where the model_deployment_ID is the ID of a successfully deployed model.

To view the replica logs, run the following command:

cdswctl models getReplicaLogs --modelDeploymentId=<model_deployment_ID> --modelReplicaId="<replica_ID>" --streams=stdout

For example:

cdswctl models getReplicaLogs --modelDeploymentId=2 --modelReplicaId="petal-length-predictor-1-2-6d6496b467-hp6tz" --streams=stdout

The valid values for the streams parameter are stdout and stderr.
