In this presentation we are going to create a Heat Map.
Sample below is a heat-map of volume-utilization of a SVC vdisk.

HEAT-MAP
A heat-map gives you a quick overview of a performance metric compared over a couple of
weeks and hours.

HEAT-MAP OF SVC NODE PROCESSOR UTILIZATION
Within TPC go to Cognos – Create performance reports.

Select – Storwize System Nodes – Node Hourly Data – Other Metrics – Processor Utilization Percentage
After selecting the metric: right-click: insert

Select – Storwize System metrics– Storage Node Data – Storage System Name
After selecting the metric: right-click: insert

Select – Storage System Name and click secties maken.

Select – Storage System Name and click secties maken.
This will result in screen on the right

Select – Storage Node Name and right-click - insert.

Select – Storage Node Name and click Create Sections.

Result: All SVC nodes by Cluster.

Add Hour .Add Date .

HEAT-MAP OF NODE PROCESSOR UTILIZATION
Select Hour and click on create crosstable.

Result of creating crosstable:

Select a cel and right-click to select summary

In the bottom select: none

Select a cel and right-click to select conditions:

Create range values with styles:

Result of a SVC Node:

Select a column (hour) and right click to Sort:
Select a ascending

Result: Save report for future use.

Instead of performance per Hour it’s also possible to create the heat-map per sample (5 minutes)
