Tracking Throughput

The Real-time Throughput section enables tracking of the amount of activity running on the instance, using the speedometer charts displayed in the following sections:

•

Logons — the rate per second of sessions that were initiated during the specified time range

•

Executions — rate per second of statement executions during the specified time range

•

Physical Data Processed — the total size (MB) of data processed through physical read and write operations during the specified time range

Monitoring Historical Activity

The History pane indicators, described in the following sections, provide information for tracking the instance activity during the time range selected at the upper right corner of the screen:

•

•

Top 3 busiest resources

The Workload chart displays the workload of the average active sessions, plotted over time.

The workload can be plotted as either:

•

Baseline — workload plotted over time

•

Breakdown — the amount of time the database spent waiting for various wait events, plotted over time

To display the wait events breakdown, click the arrow to the right of the Breakdown link.

Top 3 busiest resources

The Top 3 busiest resources section displays the three resources whose wait time constituted the highest percentage of the total active time during the specified time range.

Monitoring Alarms

The Alarms pane displays color-coded indicators of the monitored host status.

The alarms are divided into the following types:

•

Baseline deviations — invoked for several of the metrics for which a baseline is configured

•

Thresholds — displays alarms about metrics or workloads, whose configured threshold has been exceeded

When metrics or workload resources behave normally, without any deviations, the alarm representation is displayed in gray. When a configured baseline or threshold has been exceeded, alarms are displayed in colors that represent levels of severity, ranging from yellow to red. See the Foglight Online Help for details on the alarm information.

The following indicators apply to all alarm types, including thresholds.


	NOTE: The numbers displayed inside the indicators show the number of alarms encountered for each alarm type.


Indicator	Description
Yellow (Warning)	The metric (or workload resource) has exceeded the configured threshold or deviated from the baseline.
Orange (Critical)	The metric (or workload resource) has significantly exceeded a threshold or deviated greatly from the baseline.
Red (Fatal)	A severe connectivity issue was encountered, thereby triggering a fatal alarm. Such an issue can occur in one or more of the components that take place in the monitoring process; for example, if Oracle database is not responding, the listener is down, or the number of connections reached the number of sessions defined in the init.ora file.

Enabling or disabling baseline calculation

The Enable/Disable Baseline command under the Databases Technical Support dashboard allows enabling or disabling the baseline calculation for selected metrics.

To enable or disable baseline calculation:

1

Go to Dashboards > Databases > Support Dashboard > Databases Technical Support.

2

near the Enable/Disable Baseline command.

3

Select the Oracle tab.

4

Select the requested metrics under the Metric Name column.

5

Select the requested command, either Enable Baseline or Disable Baseline.
