Monitoring resources
Monitor the status, space usage, and performance of storage devices. You can also monitor the hosts and operational condition of fabrics and switches, the status of their internal resources, and the performance of switches.
Before you begin
To monitor storage systems, applications, departments, general groups, fabrics, switches, and
hosts, complete the following tasks:
- Add the storage systems that you want to monitor so that the metadata about the status, space usage, and performance of the storage systems and their internal resources can be collected and analyzed.
- Add the fabrics and switches that you want to monitor so that metadata about their condition, the status of their internal resources, and about switch performance can be collected and analyzed.
- Add the hosts that you want to monitor so that metadata about their status, space usage, performance and internal resources can be collected and analyzed.
- Create applications that define the relationships between applications and the storage resources that they use so that you can monitor the performance and space usage of applications.
- Create departments that define the relationships between departments and the applications that departments use to monitor the space usage of departments.
- Create general groups to view information about related resources in one place.

About this task
IBM Storage
Insights collects metadata about the status, configuration, capacity, and performance of your
monitored devices. Diagnostic data is also collected into log packages and added to support tickets.
The following types of tasks are used to collect that information:
- Probes
- Probes collect status, configuration, and capacity metadata once every 24 hours.
- For DS8000® storage systems and their pools, the value for used capacity is collected once every hour. To customize that interval, contact IBM Support.
- For some devices, additional probes are automatically run when specific events occur on those devices, or when many events are detected in a short time period. To avoid performance bottlenecks in those cases, probes are not run more than once every 20 minutes.
- Performance Monitors
- Performance Monitors collect performance metadata every 5 minutes.
- For Dell EMC storage systems that manage block storage, performance metadata is automatically collected every fifteen minutes.
- For IBM Spectrum® Scale storage systems that are enabled to collect performance metadata for file storage, the collection schedule can be configured when or after the storage system is added for monitoring. The intervals that can be selected for collecting performance metadata are every 5, 10, 15, 20, 30 or 60 minutes.
Metadata collection tips:
- After probes and performance monitors run, the GUI is updated automatically to display the latest metadata for your monitored devices.
- Only metadata about your monitored devices is collected. The actual data that is stored on devices is never accessed or collected.
