Charting Metric Data
Charting Metric Data
A metric chart is a graphical representation of the metric data that Hyperic HQ collects for each resource. Each resource type support a different set of metric data, so chart vary by resource type also. Charts can help you see trends in resource behavior, which can in turn be helpful for capacity planning, cost analysis, and other operational decision-making.
HQ displays all full-page metric charts in the "Metric Chart" screen, where you can adjust how the metric is displayed. (Indicator charts are more minimally displayed on the "Current Health" screen.) Consult the help for those screens for the nitty gritty about viewing and interpreting charts.

Chart Types: What They Are and How to View Them
There are three kinds of charts, and each gives you a different perspective on resource health. For any chart, you have to select the metrics to be charted: this selection occurs on the "Current Health"" screen for the resource (or for the parent group if looking at multiple resources), on the 
tab, on the 
tab, which lists all the metrics collected for the resource being viewed. The chart of the selected metric(s) is displayed on the "Metric Chart" screen.
| Type | Description |
|---|---|
| Single Metric Single Resource | This chart shows a single metric for a single resource. To chart a single metric:
|
| Multiple Metrics Single Resource | This chart shows up to a maximum of ten metrics simultaneously for a single resource, which is handy for getting an overall sense of the resource's health. To chart multiple metrics for a single resource:
|
| Single Metric Multiple (Group) Resources | This chart shows a single metric for a maximum of ten resources, which allows you to compare the behavior of different resources. The resources must be members of a single compatible group or of a single autogroup.

next to the metric whose chart you want to see.
.
To view the chart for an indicator metric:
- Instead of the tab, on the
tab, click the name of the indicator metric above the chart.
A full-page chart is displayed.
How a Chart is Constructed
A metric chart by default displays only the measured metric data values over a user-selected time frame. You can also chart peak (highest observed), lowest and highest acceptable, and average values, and you can change the time frame that the chart covers. If you are charting a single metric for a single resource, you can also establish and chart baseline values. Depending on the display range over which you are charting the metric data and whether the metric data is cumulative (for example, throughput), the values may be averaged over time.
For more information about reading a chart, read the help for the "Metric Chart" screen.
