Foglight for Oracle (Cartridge) 5.7.5.41

Defining Data Collection and Storage Options

The Foglight for Oracle agent collects and stores data at all times, even when the browser window that displays the data is not active. Use the Collection Frequencies view in the Databases Administration dashboard to specify:

•

Which collections are sampled and stored.

•

The data collection values when sampling is carried out in offline, online, and real-time frequency modes.

•

The collection frequency.

When a user is currently focusing on a screen, the sampling frequency for all of the collections associated with this screen automatically switches to Real-Time. The collection frequency setting determines the sampling frequencies of the other collections, which do not run in Real-Time mode).

The available collection frequencies, which can be selected from the field The selected agent's current collection frequency is, are:

•

Low — all collections are running in Offline mode, regardless of whether a Client is connected

•

Normal — the collections' running mode (Online/Offline/Real-time) adjusts dynamically to the Client's connection status (disconnected/connected/focusing on a screen).

•

High — all collections are running in Online mode, regardless of whether a Client is connected.

•

The Query timeout for on-demand collections.

This setting defines the number of seconds that a query for on-demand collections can run before it times out.

On-demand collections are collections whose data is retrieved not by predefined time intervals but upon entering a screen or clicking a button.

The default setting of this parameter is 60 seconds, but it can be modified by clicking the number that indicates the parameter’s value in the field Query timeout for on-demand collections:.

The Collections table contains the following columns.

Table 30. Collections
Column	Description
Collection Enabled	Defines whether the selected collections are sampled and stored.
Collection Name	The name of the collection. This list is sorted in alphabetical order.
Offline Frequency (Sec)	Used for defining the collection interval, in seconds, in offline mode (for example: 300). Offline frequency refers to the longest interval possible for sampling the monitored instance.
Online Frequency (Sec)	Used for defining the collection interval, in seconds, in online mode (for example: 60).
Real-time Frequency (Sec)	Used for defining the collection interval, in seconds, in real-time mode (for example: 20). Only one collection can be sampled at real-time frequency at any given moment.
Query Timeout (Sec)	The amount of time, in seconds, that elapses before the query times out.


	IMPORTANT: In the Normal collection frequency, when the browser window that displays Foglight for Oracle is active, the collection frequency mode in the active screen (for example: the Current Sessions panel in the Activity drilldown) switches to the fastest frequency possible - once every 20 seconds.

To modify the values of a specific collection:

Select the collection’s row in the table.

Click Edit.

The Edit the Collection dialog box opens.

Select whether to enable the collection and storage of the selected collection.

Set the collection interval, in seconds, in offline frequency mode (if available).

Set the collection interval, in seconds, in online frequency mode (if available).

Set the collection interval, in seconds, in real-time frequency mode.

Set the query timeout, in seconds.

Click Set to apply these settings or Cancel to reject them.

Customizing Alarms for Foglight for Oracle Rules

Many Foglight for Oracle multiple-severity rules trigger alarms. To improve your monitoring experience, you can customize when alarms are triggered and whether they are reported. You can also set up email notifications.

This section covers the following topics:

•

Introducing the Alarms View

•

Setting and Modifying Alarm Sensitivity Levels

•

Modifying Alarm Settings

•

Configuring Email Notifications

•

Cloning Agent Settings

•

Reviewing Rule Definitions

Introducing the Alarms View

The Alarms view enables you to modify global settings and agent-specific settings for alarms.

To open the Alarms view:

Open the Administration dashboard as described in Opening the Databases Administration Dashboard .

Click Alarms.

The list of agents that you selected on the Databases dashboard is shown in the upper right corner of the view.

From the Alarms view, you can complete the following tasks:

•

Setting and Modifying Alarm Sensitivity Levels

•

Modifying Alarm Settings

•

Configuring Email Notifications

•

Cloning Agent Settings

Setting and Modifying Alarm Sensitivity Levels

Foglight for Oracle has three sensitivity levels that control which alarms are reported:

•

Essential — Enables only the most important alarms.

•

Normal — Enables a selection of alarms from different rule categories, including all Essential alarms.

•

Tuning — Enables all alarms.

You can change the sensitivity level assigned to each agent. If a sensitivity level does not include all the alarms you want to track or includes too many alarms, you can view a list of multiple-severity rules and modify the sensitivity level that is mapped to each severity.

Changes made to a sensitivity level affect all agents that are assigned that sensitivity level. If you want to enable or disable alarms for the selected agents, see Enabling or disabling alarms for selected agents .

Setting the alarm sensitivity level by agent

Each agent has its own sensitivity level setting. The default is Normal.


	TIP: Select a sensitivity level that is closest to what you want, then customize it as necessary. For instructions, see “Viewing and modifying alarms assigned to severity levels” on page 177.

To change the sensitivity level used by an agent:

In the Alarms view, click the Sensitivity Level tab.

Select the check boxes for agents you want to edit, and then click a sensitivity level button, such as Essential.

Click Save changes.

Viewing and modifying alarms assigned to severity levels

You can view a list of multiple severity rules to see which severities are assigned to which sensitivity level. If desired, you can change the assignments. Changes to sensitivity levels affect all agents.
