Using the Currently Selected Database Group Table

The currently selected database group table displays the columns listed below.

 
 
Name
Description
Instance

Sev

The highest severity alarm of the DB2 database (whether a database instance, RAC or RAC node), which determines the database’s health state.

Name

The name of the DB2 instance, RAC or RAC node. In addition, this row includes the Go to Home Page button.

Version

The version number of the DB2 database instance.

Up Since

The date and time that the DB2 database instance (or, in a RAC, the instance that was the earliest to restart) was last restarted.

Workload

The workload (average active sessions) for the DB2 database instance or RAC. When holding the cursor over the workload graph, the dwell displays a chart that shows the workload history over the specified time range.

DB Alarms

The number of warning, critical, and fatal alarms for the DB2 database instance/RAC.

When holding the cursor over one of the alarm counts, the dwell displays the most recent alarms invoked for this database, 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 for details on the alarm information.

System Utilization

Host

The name of the computer that is hosting the database instance or RAC.

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.

Disk (% Busy)

The percentage of time the busiest device spent serving system-wide input/output requests. This metric serves as a measure for the system I/O load.

Monitoring Status

Agent

The operational status of the monitoring agent.

When the agent instance is running, the State icon () is green, and holding the cursor over the icon displays the message Collecting Data.

When the agent instance is running but not collecting data, holding the cursor over the icon displays one of the following status messages listed below.

•
Starting
•
Stopped
•
Stopping
•
Unknown

When SQL PI is configured the SQL PI icon is displayed.

OS

The status of the OS data retrieval.

NOTE: While the Foglight for DB2 LUW agent retrieves OS data, several OS metrics cannot be retrieved without the Infrastructure cartridge agent. IF OS monitoring was disabled during the creation of the Foglight for DB2 LUW agent through the Oracle Monitoring Installer wizard, the wizard cannot automatically create the Infrastructure cartridge agent; However, this agent can be created manually using the Dashboards > Hosts > Hosts dashboard. For details, see Adding a Monitored Host in the Managing the Infrastructure Cartridge User and Reference Guide.
NOTE: If the Infrastructure agent was created, but OS database is collected only by the Foglight for DB2 LUW agent, click the OS status to OS data collection through the Infrastructure agent.
