The Capacity Heat Map shows a weekly view of how often application or infrastructure capacity gets close to its configured limits. Only Capacity KPIs feed it. Each Capacity KPI represents a resource limit in the application’s infrastructure or code.

Open the heat map

1. Open the Application Summary page. See Application Summary.

2. Click View Capacity Heat Map.

Capacity KPI categories

Infrastructure level.

• CPU. KPIs for CPU consumption.
• Memory. KPIs for memory consumption.
• I/O. KPIs for I/O levels.

Application level.

• Application. KPIs for virtual resources like thread pool, DB connection pool, DB locks, and DB sessions.

What’s on the screen

1. Application name. The application this heat map is for.

2. CF Baseline Timestamp. The timestamp of the last completed CF baseline. The duration defaults to the number of months covered by the last baseline. Available views: 1, 2, or 3 months. The baseline starts at the displayed date and time and goes back 60 days.

3. Workload Mix. A combination of transactions of different types. Shows volume growth over selected data points using a stacked bar of the top 10 transactions.

4. Bubble size in Capacity KPIs. The bubble size shows frequency, that is, how often the KPI value approached its maximum limit during the week. Hover any bubble to see five frequency buckets, with the first being the most severe and the last the least.

5. Bubble color in Capacity KPIs. Five shades of red. The darker the shade, the closer the KPI is to its limit.
