How should a Portworx administrator enable the Alertmanager?
A.
Create a config map with the Alertmanager configuration and enable Alertmanager via the pxctl CLI.
B.
Create a secret with the Alertmanager configuration and enable Alertmanager in the StorageCluster object.
C.
Deploy Alertmanager by following the official Alertmanager documentation and integrate it with Portworx by enabling monitoring webhook in the StorageCluster object.
Comprehensive and Detailed Explanation From Exact Extract:
Enabling Alertmanager in Portworx involves creating a Kubernetes Secret containing the Alertmanager configuration (such as alert routing rules and notification channels) and referencing this secret in the Portworx StorageCluster manifest. This integration allows Portworx’s monitoring stack to forward alerts to Alertmanager for centralized alert processing and notifications. Unlike ConfigMaps, which are generally used for non-sensitive data, Secrets protect sensitive alert configuration. Enabling Alertmanager via pxctl CLI is not supported as Portworx relies on Kubernetes declarative configuration for monitoring components. Additionally, deploying Alertmanager independently and integrating through webhooks requires manual setup but is not the recommended or integrated approach. Portworx official observability documentation details the secret-based configuration as the standard and secure method to enable and manage Alertmanager within Portworx clusters for robust alert handling【Pure Storage Portworx Monitoring Guide†source】.
