Using Capacity Utilization recommendations

The IBM FSM Capacity Utilization gauges represent categories of utilization assessment. In addition to the status of each utilization gauge, the Capacity Utilization dashboard shows recommendations for each gauge that has a warning (yellow) or critical (red) status. If you complete the recommended action, the capacity utilization will be optimal.

Recommendations for individual capacity and resource utilization gauges are consolidated the Overall Utilization status and displayed at the top of the dashboard. If you complete the recommendations, the utilization gauge status changes after the management node is polled again, after either the next polling interval or after a few polling intervals. If the calculated utilization for a gauge exceeds the critical threshold for a gauge, the status is red and an actionable recommendation is displayed at the top of the dashboard. If you complete the recommendation, the utilization gauge status changes after the management node is polled again.

For example, if there are 13 average active user sessions on your management node over the last eight hours, the Average active users status is red, and the displayed recommendation is: Reduce the average number of concurrent users to 10 or less. If you end three of the 13 active sessions, the Average active users status is green after the management node is reassessed by the monitoring service after a few polling intervals.

Note: The CPU, memory, disk IO, and active user gauges measure capacity that changes often. Therefore, these gauges display the average capacity utilization over the last eight hours. If a gauge has a status of Unknown, more data sampling must occur before the status can be assessed.

To view the recommendation for each gauge in the Capacity Utilization dashboard, move the mouse pointer over the question-mark icon for the gauge.

The following table provides links to documentation that might help you complete the recommendations, organized by each capacity or resource utilization gauge.

Gauge	Recommendation	Related information
Current managed endpoints	Reduce the number of managed endpoints.	See the topics in the section Unmanaging a chassis for information about removing managed compute nodes, virtual servers, and compute node operating systems.
Current managed endpoints	Manage additional endpoints.	See Discovering systems and collecting inventory data.
Average active users	Reduce the number of concurrent users.	See Users tab for information about using the web interface to end user sessions.
	Reduce the number of concurrent users.	See endSession command for information about using the command-line interface (CLI) to end user sessions.
	Add users.	See Users tab for information about creating users.
Average CPU utilization Average disk IO utilization Average memory utilization	Reduce CPU, disk IO, and memory usage.	Reduce the amount of concurrent activity by increasing the Verify Connection Interval and Query Vital Properties Interval for each managed resource type. From the IBM FSM Explorer, click Utilities > Management Server.
		Schedule tasks for non-peak hours. See Tasks and scheduled jobs commands for information about using the CLI to specify when jobs and tasks are run.
		Use discovery profiles to reduce discovery activity. See Discovery profiles.
		Use inventory profiles to reduce inventory activity. See Inventory data and collection profiles.
		Reduce the number of concurrent discoveries or inventories that are performed by submitting smaller groups.
Current disk space utilization	Reduce disk space usage.	If the /home partition is full, remove unneeded operating system images, update files, or other large files that were copied to the management node. Delete any unneeded, large files (greater than 500 MB) from the /home/pe directory. See Removing update files.
		If the /var, /, /boot, or /opt partition is full, contact IBM Support.
		If the /updateslib partition is full, remove unneeded update files with the cleanupd command. Use the cleanupd command to clean (or delete) update files and information from the update library.
		If the /mirror0 partition is full, use inventory profiles to reduce the amount of inventory data that is collected. See Collecting and viewing inventory data.
		If the /tmp partition is full, restart the IBM Flex System Manager management node to clear the disk usage condition. See Turning off the management node for more information.
