Monitoring the health of cloud services software

Use the mmcloudgateway command to monitor the health of cloud services.

To monitor the status of cloud services, issue a command according to this syntax:

mmcloudgateway service status [-N {alltct | Node[,Node...] | NodeFile | NodeClass}]
   [--cloud-storage-access-point-name CloudStorageAccessPointName] [-Y]

For example,

To check the status of all available transparent cloud tiering nodes in your cluster, issue this command:

mmcloudgateway service status -N alltct

The system displays output similar to this:


 Cloud Node Class:  tct

To check the status of all available transparent cloud tiering nodes in a specific node class (TctNode), issue this command:

mmcloudgateway service status -N TcTNode

The system displays output similar to this:


Cloud Node Class:  TcTNode

To check the status of all available transparent cloud tiering nodes in a specific CSAP, issue this command:

mmcloudgateway service status -N TctNode --cloud-storage-access-point-name swift-point

The system displays output similar to this:


Cloud Node Class: TctNode

Note: ONLINE status here means container exists on the cloud, but it does not guarantee that the migrations would work. This is because there could be storage errors on object storage, due to which new object creation might fail. To verify container status for migrations, issue the mmcloudgateway containerpairset test command.

For more information on all the available statuses and their description, see transparent cloud tiering status description..

GUI navigation

To work with this function in the GUI,

Log on to the IBM Storage Scale GUI and select Files >Transparent cloud tiering
Log on to the IBM Storage Scale GUI and select Monitoring>Statistics

Additionally, you can check the cloud services status by using the mmhealth node show CLOUDGATEWAY command.
