Viewing Data about the Exadata Cells

The table displayed in the Exadata tab contains the following columns.

Table 4. Exadata table
Name	Description
Exadata
Sev	The highest severity alarm invoked within all cells monitored by the selected agent, which determines the agent’s health state.
Name	The name of the Exadata agent.
Version	The version number of the Oracle Linux used for running the Exadata storage server.
Online Cells	The number of cells monitored by the selected agent that are currently online.
Temperature Status	The temperature status of all cells monitored by the selected agent, as provided by the Baseboard Management Controller (BMC); indicates whether the temperature is normal. Any deviation from the normal temperature value, which is determined by Oracle, invokes an alarm indicated using an orange color on this column.
Total Read Rate (Mb/S)	The rate (megabytes/second) at which data was read from all celldisks during the specified time range.
Total Written Rate (Mb/S)	The rate (megabytes/second) at which data was written on all celldisks during the specified time range.
Alarms	The number of warning, critical, and fatal alarms for the celldisks. When holding the cursor over one of the alarm counts, the dwell displays the most recent alarms invoked for these celldisks, sorted by severity. Clicking this field displays the Alarms list, which is listed by severity order. See the Foglight Online Help, “Monitoring System-Wide Alarms” topic for details on the alarm information.
System Utilization
CPU Load (%)	The overall operating system CPU usage by all processes (including CPU usage by the database).
Memory (%)	The percentage, within the total memory, of memory consumed by all operating system processes (including the database). This value includes both RAM resident memory and swapped memory.
Monitoring Status
	Indicator whether data is being collected.

Foglight for Oracle Overview Dashboard

Foglight for Oracle Overview Dashboard

The Foglight for Oracle Overview dashboard provides various detailed views that are accessible using the toolbar.

The Overview dashboard contents depends on whether a RAC (Real Application Cluster) or an Oracle database instance is selected.

Breakdown and Baseline Chart Formats

Several charts can display information in either of the following formats:

•

Baseline format — where a selected individual metric is displayed as a single line.

•

Breakdown format — a representation of actual activity of a metric or a set of metrics, compared with the typical behavior of these metrics for the selected time range. A breakdown display can also present a single metric divided into various components. For example, space utilization is broken down by the various components that occupy the space.
