Setting up Metrics and Monitoring

WHY DO WE MONITOR?


<insert list here>

WHAT SHOULD WE MONITOR?


HOW DO WE MONITOR?


INSTALL OEM 12C


1.  Add Targets •  Deploy EM Agent to Hosts •  Promote Targets

2.  Add Metrics and Metric Extensions •  Set Thresholds •  Monitoring Templates and Template CollecLons

3.  AdministraLon Groups •  Automate sePng of metrics and incident rule sets

4.  Create Incident Rules/Rule sets •  Availability Rules •  Metric Rules

5.  Job Library •  Automate everything



2.  Add Metrics and Metric Extensions •  Monitoring Templates and Template CollecLons





Metric Thresholds


Monitoring Templates and Template CollecLons

!


AdministraLon Groups


Create Incident Rules/Rule sets


•  Create central administrator to own Incident Rule Sets, Templates and Jobs

•  OEM_ADMIN •  Test Incident Rule Sets periodically

•  Create Like or Use Private Rule Sets •  Use the Metric threshold test

•  Use CorrecLve AcLons •  Incident Manager •  Extend monitoring

•  Storage Plug-‐ins •  EM Extensibility Exchange

•  Automate rouLne tasks using EMCLI

Top 10 Features for DBAs

1/ Database Lifecycle Management

■  Database Patching & Updates ▪  Patch Types

—  PSU

—  CPU

—  One-offs

—  Opatch

▪  Manual patching —  Time consuming

—  Complex

—  Risky

—  Requires downtime


■  Database Upgrades ▪  Upgrades can be scary

—  Pre-requisites

—  Backups

—  Down-time

—  Cross-fingers


■  Database Patching & Updates ▪  Use Patch Plans ▪  Out of Place Patching support ▪  Integrates with MOS


■  Database Patching & Updates ▪  5 Step Process to patch many DBs

—  Patch Description

—  Select the patches to apply and the targets

—  Deployment options

—  Patch Validation & Analysis

—  Review and Deploy

▪  More automation with EMCLI —  emcli submit_patch_plan

2/ Real-Time Database Operations Monitoring ■  Simple Statements

▪  SQL Monitoring ▪  PL/SQL Monitoring

■  Composite Database Operations ▪  Enabled by default when STATISTICS_LEVEL=TYPICAL/ALL

■  Define DB Operation ▪  DBMS_SQL_MONITOR.BEGIN_OPERATION ▪  DBMS_SQL_MONITOR.END_OPERATION

2/ Real-Time Database Operations Monitoring ■  SQL Monitoring

3/ EM Command Line Interface

■  Turbo charges EM! ■  Enables Script Automation ■  Install from OEM Console ■  Standard or Advanced with Scripting Option


•  emcli help •  emcli verb help

4/ ASH Analytics

■  Multi-dimensional view of ASH data ■  DB-Time Analysis ■  Top Activity +

▪  Resize sample window ▪  More dimensions ▪  Load map tree

4/ ASH Analytics

5/ Backup & Recovery

When I ask the sysadmins, “The backups are making it to tape, right?”

-DBA Reactions


■  RMAN Backup ▪  Target-based RMAN backup

—  Wizard-driven interface

—  Oracle-Suggested or Customized Backup

▪  Job System based RMAN backup —  Use existing RMAN scripts

▪  Group Backups using deployment procedure —  Backup multiple databases, homes and filesystems in a single

operation

6/ Corrective Actions

■  Resolve Incidents, Automagically! ■  Automate routine administrative tasks ■  Triggered in response to metric alerts ■  Runs on the target on which alerts are triggered ■  Agent-side response actions can execute single commands

or scripts on host

7/ Automatic Database Diagnostics Monitor ADDM

Compare Period ADDM

“Why is the database slower today than yesterday?” Compares database activity over two periods of time


■  Real-Time ADDM ▪  Analyzes hung or very slow DB ▪  Finds sources of contention ▪  Performs DB Time Analysis ▪  Uses 2 connection modes

—  Normal JDBC connection

—  Latch-less connection

▪  Enhanced Real-Time ADDM (DB 12c)


Real-time ADDM Active Reports

8/ Database-as-a-Service

■  Schema-as-a-Service ■  DBCA Template ■  RMAN Backup ■  Snap Clone

▪  Storage Agnostic (ZFS) ▪  Vendor Specific (NetApp, Oracle ZFSSA, EMC)

■  Pluggable Databases (12c)

8/ Database-as-a-Service

■  Database-as-a-Service

9/ Metric Extensions

Not satisfied with out-of-the-box metrics?

BYOM…

…Build Your Own Metrics


•  Many out-‐of-‐the box metrics available •  If there isn’t you can create your own •  Create using adapters

•  SQL •  PL/SQL •  Shell Scripts

•  Useful for re-‐using exisLng scripts


•  Flash Recovery Area (FRA) being used •  Archived Used (%) doesn’t trigger •  Recovery Area (%) Used not modifiable

•  Warning 85% •  CriLcal 97%

•  Create new FRA Used (%) Metric •  See New EM12c Extensibility Exchange for

examples

Example

10/ AWR Warehouse (AWRW)

■  Used for consolidation of AWR from multiple databases ■  Provides long term historical information for AWR ■  Data is moved from source to targets system via ETL jobs ■  Retention period can be modified ■  See MOS note 1907335.1 for patches and requirements

10/ AWR Warehouse (AWRW)
