Applications

Monitor the capacity, the space usage, and the performance of the applications and the application subcomponents in your data center.

To monitor the capacity, space usage, and performance of applications and their subcomponents, you create applications and application subcomponents and then add filters to associate storage resources with the applications and the application subcomponents.

Information about applications

The following information is available for each monitored application and application subcomponent:
Tip: You can add or edit some of the properties of the application after you create it such as the name, type, and subtype. Right-click the application and click View Properties. Click Edit and make your changes.
Block Capacity (GiB)
The total amount of block storage space that is allocated to the volumes for the application. For example, if the filter associates a volume resource and a hostresource with the application, the block capacity includes the capacity of the volume and the capacity of the volumes that are assigned to the host. The capacity of the mirror copies and replication targets for the volumes is also included.
Custom tag 1, 2, and 3
Any user-defined text that is associated with an application. This text can be included as a report column when you generate a report for applications. To edit the custom tags for an application or add a custom tag, right-click it and select View Properties and click Edit.
Departments
The name of the department that the application belongs to. If the application belongs to more than one department, the number of departments is displayed.
File Capacity (GiB)
The total amount of file-level storage space that is allocated to file systems that belong to the application, either directly or through related resources. The space is exported space, which is the space on the file systems that is made available to remote clients over a network. For example, if the application contains a file system and a host, the file capacity includes the capacity of the file system of the export and the capacity of the file systems that are mounted by the host.

If the application contains a fileset and the fileset has a quota that is defined, the file capacity is the hard limit of the quota. If the fileset does not have a defined quota, then the file capacity is the capacity of the file system on which the fileset is based.

Name
The user-defined name that was assigned to the application when it was created.
Object Capacity (GiB)
The total amount of storage space that is used by all the vaults in the application and, if applicable, in the application's subcomponents. This value does not include space that is reserved for disk overhead and dispersal overhead.

This column applies only to IBM Cloud Object Storage.

Hosts
The IP address or fully qualified domain name of the host in the application. If there is more than one host in the application, the number of hosts is displayed.
Subtype
An extra category that you can use to distinguish the application from other applications. For example, you can organize you database applications by the environment that they use such as test, preproduction, and production.
Type
The categorization of the application to distinguish it from the other applications that you create. For database applications, for example, you can organize your applications by the database vendor such as IBM® for Db2®.
Vaults
The number of vaults from IBM Cloud Object Storage that are included in the application. For more information about the vaults, click the number.
Volumes
The number of storage volumes that are used by the application. For more information about the volumes, click the number.

View performance

View the aggregated performance information for all of the volumes that are associated with an application in the performance view. By default, the Total I/O Rate and the Total Data Rate are displayed in the performance chart. You can also select to display the read and write I/O rates, and the read and write data rates in the chart.
Tip: To add or change the metrics that are displayed for a resource, click the select metrics icon select metrics icon and select the metrics to display.
Note: The application performance feature isn't available to all IBM Storage Insights users. Look for news from IBM about when this feature will be available to you.
