The following IBM Spectrum Scale services can be managed through the Services page in the GUI.
GPFS daemon
The GPFS daemon performs all I/O operations and buffer management for GPFS. You can perform the following actions from the GPFS Daemon section:
CES
The cluster export service (CES) provides highly available file and object services by using NFS, SMB, and Object protocols. The nodes that support these protocol services are referred as CES nodes. You can perform the following actions from the CES section:
CES network
Provides the details of the nodes that are part of the CES network. You can perform the following actions from the CES network section:
NFS
You need to configure the NFS services on the system to use NFS protocol for data transfer between client and the IBM Spectrum Scale system. You can use NFSv3, NFSv4, or both to use for communication between server and client. You can perform the following actions from the NFS section:
- Start and Stop NFS service
- View the details and health status of the NFS service that is configured on the CES nodes
- View the events that are raised against the NFS service
- Configure the lease lifetime, domain, and NFS protocol version at the NFS server level
SMB
You can monitor the SMB service and change global SMB configuration parameters from the GUI.
The following options are available under the respective tabs in the SMB section:
Object
You need to enable and start the object services to use the Object Storage facility.
You can monitor start, and stop object service on all or individual CES nodes, from the Object section in the Services page. In addition, object specific events and object administrator credential settings can also be managed from this section.
File authentication
Use the File Authentication section to view the existing authentication method that is used for NFS and SMB users. You can also view the events that are reported against the authentication configuration.
Object authentication
The Object Authentication section shows the existing object user authentication configuration details and the events that are raised against the object authentication service in the cluster.
Hadoop connector
The IBM Spectrum Scale system provides access to the Hadoop Distributed File System Transparency (HDFS) clients. You can monitor the status of the HDFC transparency service from the Hadoop Connector section of the Services page.
GUI
The GUI service manages the GUI, and REST APIs that are used to configure, monitor and manage the IBM Spectrum Scale system. You can perform the following actions from the GUI section:
- Monitor the GUI node configuration in the cluster
- Configure a login message. This message appears in the login page of the GUI, which is typically used to display some important information that needs to be shared with the users who are attempting to log in.
- Configure session timeout.
- Create SSL certificate request
- Install self-signed certificate or certificate issued by the certificate authority
- View the certificate information of the GUI node
Performance monitoring
The performance monitoring tool collects metrics from various components of the IBM Spectrum Scale system and provides performance information.
The Performance Monitoring section in the Services page organizes the monitoring and configuration aspects of performance monitoring under the following tabs:
File auditing
The file auditing logs data access to the files. Each file operation is generated as a local event on the node that serves the file operation.
The following details are available in the File Auditing section:
Message queue
The message queue collects and stores events that are published by the producers running on nodes in an IBM Spectrum Scale cluster. This provides a scalable infrastructure for file auditing services.
