Performance Graphs

The following performance graphs are available:

Sample Values Graph

Displays a single attribute.

Use this graph to see the raw values of the 12 most recent samples. Where applicable, that is for gauge attributes, this graph also displays the baseline values.

Sample Hourly Rates Graph

Displays a single attribute.

Use this graph to see the equivalent rates per hour of the 12 most recent sample values. Baselines are also displayed.

Hourly Summary Graph

Displays a single attribute.

Use this graph to see the hourly summary values for the last 24 hours. Hourly summaries are aggregated from all of the samples taken during that hour. Baselines are also displayed.

Attribute Types

The following types of attributes are available:

Gauge

Displays a non-negative numeric value that may increase or decrease in a range. For example, processor memory usage varies between zero and the physical limit of the hardware.

Counter

Displays the rate of increase in units per hour in a sample period. The rate is derived from sample data, which is an accumulated count that increases in value over time (for example, bytes received). This type is also referred to as COUNT.

Enumerated

Displays the value from a defined set of discrete values. For example, the state of a device can be ACTIVE or INACTIVE. Multiple values are aggregated so that a percentage of a particular value over time is available. This type is also referred to as ENUM.

Total

Displays the rate of increase in units per hour in a sample period. The rate is derived from sample data, which is the total increase in value in a sample period.
