Summary

Auto-Discovery
• A way for EM12c to automatically search
environment for targets.
• Must be set up in EM

• Main Targets are ready to be configured, simple
set up via the console.

Monitoring Templates
• Sets distinct, consistent monitoring for
individual targets or groups.
• Still allows for individual metric policies and
thresholds to be set and not overridden by
templates.
• Easy to maintain and can be automated to be set
as “default” template for targets/groups.

Creating a Monitoring Template

• Or part of administration group creation step.
• Preference to create Templates outside of group
setup.
• Plan out templates required before building.
• Build out any and all target type templates, but don’t
feel you are required to create a template for all!

Monitoring Template Design
• Base Templates off Existing Targets
• Build by Target Type
• Make Templates DEFAULT for Crucial Target
Types.

Incident Rule Sets
• Two Default Rule Sets
• “Create Like” for the Default Rules
Sets
• Build out New Ones
• Disable the Defaults

A Rule Set Can…..
• Be assigned to a Target, Target Type or a
GROUP.
• Build out rule sets as complete as you need.

Rules
• Think about…
▫ What is important to be ACTUALLY notified for?
▫ What is TRULY mission critical?
▫ What should be managed during the business
day?
▫ More notifications are NOT better notifications
▫ No, NO WHITE NOISE- make every notification
count.

Defining Rules for Efficiency
• From default rule, but have eliminated all
categories but Availability and Capacity that are
Critical.
• Email who is required to be notified AND
• Set the owner and the priority in the incident.

The Rest of the Categories
• Created a second rule
▫ Still severity has to be critical
▫ Covers all categories removed from original rule.
▫ No email notification- I want these to just create
an incident.
▫ Sets the owner and the priority automatically.

Auto-Clear of Metric Rules
• Update how long till auto-clear
• Remove notification- no, I don’t want an email!

What about Warnings??
• No, there aren’t any rules set for warnings.
• I choose to use the incident manager to track
warnings and pro-actively manage from it.
• Severity Warning, creates and incident, sets the
owner to Sysman and priority to LOW.
• This is a PROFESSIONAL PREFERENCE.

When to Know to Change a Rule
• Notification does not provide value.
• Notification is triggered by a bug, isn’t critical or
can’t be resolved by the one notified.
• Always retain the email notification to ensure
you are editing the correct notification.
• Break down the rule to ensure that metrics
grouped in one category are not mistakenly set
to not notify.

Edit the Rule from the Rule Set..

Search the Target Type and Metric

Add the Device to Exclusion List

Tips on Event Building
• Create New Rules and Break Down Categories
• Inspect Each Notification the Impacts Effective
Alerting.

• Recognize when a metric threshold vs. a rule set
is the “culprit”.

Edit Actions
• Choose if this should be done for all actions.
• Create Incident, automatically assign.
• Set a priority and even update information
automatically in the incident.

Incident Management
• Critical Notifications are now ONLY for Mission
Critical and Production Down
• The Incident Manager interface now can be
utilized for review and management.

An Incident

High Level Information regarding incident and links to details.

Incident Events
Steps covered in incident and escalation.

Incident Updates
• Steps through the updates to the incident.
• If any notifications have been sent, this is where
you look!

Editing Thresholds for Incidents
• If Metrics Involved, Edit from Incident:

Set the New Metric Thresholds
• Suggestions Have Verified- no Guessing.
• Upped Number of Occurrences to Eliminate
False Alerts
• Choose if Monitoring Templates Can Override.

Groups and Admin Groups
• Groups ease management of targets, allowing
assignment of tasks, monitoring and other features
through a single alias for multiple targets.
• Groups are still supported, but limited vs. what
Administration groups offer you. The one
advantage is multiple group assignment of a single
target.
• Administration groups set hierarchy and automate
management by assigning monitoring templates,
compliance standards, and cloud policies.

Groups- Simple
• Original, Backward Compatible Groups
• Add targets to a group or more than one group
at any time.
• Edit standard groups down the road.
• Groups can be used with rule sets to assign alerts
to multi-level escalation in actions.

Administration Groups- Complex
• Plan out first, including “Line of Business”,
“Lifecycle Status” and what types of databases
exist in environment, (production, mission
critical, staging, development, QA, etc.)
• Once created, most design elements of the
Administration group are not open to edits.
• All hierarchy for each target is available in the
“target properties”.

Setting up Admin Groups
• Click on Targets, Groups OR Setup, Add Target,
Administration Groups
• Create, Choose Administration Group

Have your design ready…

Creation of a Hierarchy
• Start with Lifecycle Status
• Decide which to keep, edit, add, remove or merge.

Create Your Line of Business
• Click on “Add” in Hierarchy Levels, (again)

• Choose Line of Business, click on Add, separate
by a comma all lines of business desired.

Simple Hierarchy is now built
• Development Hierarchy, (same for each
Lifecycle status)

Create Hierarchy
• Click on Create, warning will appear-

• Monitoring Templates, (covered earlier), can
be created as part of this step.
• Compliance and Cloud standards must be
created in the appropriate framework in
EM12c before being added to the
Administration Group.

Create the Template Collections
• Add all monitoring templates required of any life
cycle.

• Note- No associations exist yet!

Run Unassociated Target Report
• Run Report to see what targets aren’t associated
with Admin Groups.

Editing a Target
• Fill in all Pertinent Information

Post Association
• Associate Template Collection
• Continue with all Targets Till
Complete.

Dynamic Groups
• High Level Review

Define the Membership Criteria

Reviewing the Build
• The Membership can now easily build out from
the criteria entered.
• Saves from having to build Admin Groups.

Charts
• Use Default Charts to Begin

Keep it Simple
• Use Default for Charts, Columns, Dashboard

Group Review
• Dynamic Easier, Fluid
• Administration- more complex, but open to
more errors.

Step by Step Example

Summary-How This Works Together
• Automate▫ Monitoring Templates
▫ Rule Sets
▫ Dynamic Groups over Administration Groups

• Efficiency
▫ Remove notifications that create “white noise”.
▫ Update metric thresholds.
▫ Silence metrics that offer no value.

Information Publisher Reports
• Canned Reports
• Simple “Create Like” feature
• BI Publisher currently an option, Release 3,
embedded.
• Requires MGMT_VIEW grant to select objects.
• Fully qualified names not allowed in queries.

IP Reports Interface
• User Friendly
