Seldon Core is an open-source platform designed to deploy machine learning models on Kubernetes. It provides a robust framework for scaling, managing, and monitoring machine learning models in production environments. By leveraging Kubernetes, Seldon Core allows for seamless integration and scalability, making it a popular choice for organizations looking to operationalize their machine learning workflows.
One common symptom that users may encounter when using Seldon Core is the lack of effective monitoring of model servers. This can manifest as an inability to track model performance metrics, unexpected downtimes, or difficulty in diagnosing issues with deployed models. Without proper monitoring, it becomes challenging to ensure the reliability and performance of machine learning models in production.
The primary root cause of monitoring issues in Seldon Core is often the lack of integrated monitoring tools or misconfigured monitoring settings. Seldon Core relies on external tools like Prometheus and Grafana to provide monitoring capabilities. If these tools are not properly configured or integrated, users may face challenges in tracking and analyzing model performance metrics.
To address monitoring issues in Seldon Core, it is essential to ensure that the necessary monitoring tools are installed and configured correctly. Below are the steps to set up and configure monitoring for Seldon Core:
Prometheus is a powerful monitoring and alerting toolkit. To install Prometheus, you can use Helm, a package manager for Kubernetes:
helm install prometheus stable/prometheus
Ensure that Prometheus is running and accessible within your Kubernetes cluster.
Grafana is used to visualize the metrics collected by Prometheus. Install Grafana using Helm:
helm install grafana stable/grafana
After installation, access the Grafana dashboard and configure data sources to connect to Prometheus.
Ensure that your Seldon Core deployment is configured to expose metrics. This can be done by setting the appropriate annotations in your SeldonDeployment YAML:
apiVersion: machinelearning.seldon.io/v1
kind: SeldonDeployment
metadata:
annotations:
prometheus.io/scrape: 'true'
prometheus.io/port: '8000'
These annotations enable Prometheus to scrape metrics from the model server.
Use Grafana to create dashboards that visualize the metrics collected by Prometheus. You can find pre-built dashboards for Seldon Core here.
By following these steps, you can effectively monitor your Seldon Core deployments and ensure that your machine learning models are performing optimally. Proper monitoring not only helps in diagnosing issues but also aids in maintaining the reliability and performance of models in production.
