This document discusses how to use Oracle Exachk and Oracle Enterprise Manager 12c to monitor Oracle Exadata systems. It describes how to run Exachk regularly to check the health of Exadata and review the output reports. It also explains how to configure Oracle EM 12c with the Engineered System Healthchecks plug-in to monitor Exadata and generate alerts. Running Exachk through the daemon allows it to run across all cluster nodes. The plug-in places results in EM metrics and templates can disable unwanted alerts.

- Daemon
- Plug-In/Agent Interaction
- EM Outputs

5. ExaChk Tool
Where to get it:
MOS Note ID: 1070954.1 – Exachk or Healthcheck
Current release: 2.2.5.2_20140815
When to run:
On a regular basis (30 days)
After corrective actions performed on a failure

6. ExaChk Tool
Run ExaChk:
$ cd <exachk unzip location>
$ ./exachk –a
Note: Follow the prompts and provide passwords

7. Exachk Outputs

8. Enterprise Manager 12c Approach

9. Prerequisites
Note: 757552.1 - Oracle Exadata Best Practices
Note: 1110675.1 – Oracle Database Machine Monitoring Best
Practices
Oracle Exadata Configured and Monitored
Oracle Engineered System Healthchecks Plug-In (12.1.0.5.0)
Oracle Enterprise Manager 12c (12.1.0.2, 12.1.0.3, or 12.1.0.4)

10. Environment Info
RAT_COPY_EM_XML_FILES : Enables copying of result files on all the
cluster
export RAT_COPY_EM_XML_FILES = 1!
RAT_OUTPUT : Output path for the exachk output
export RAT_OUTPUT = /U01/ORACLE/EXACHK_RPT!

11. Daemon
Exachk daemon makes it possible to run the ALL (-a) option of the
Exachk tool in silent mode.
Start the daemon as the Oracle user (follow the prompts)
./exachk –d start!
Run Exachk by using the daemon
./exachk –daemon –a!
Note: Same process can be used to run Exachk on Exalogic

12. Daemon (Cluster)
Run the daemon as the Oracle user with cluster support
./exachk –clusternodes [node1,[node N]] –d start!
Run Exachk by using the daemon
./exachk –daemon –a!
Note: Now exachk can run across all nodes in the exadata (if needed)

13. Plug-In
Check for any new plug-ins
!Setup -> Extensibility -> Self Update -> Plug-Ins!
!Search for HealthChecks!
!
Apply to OMS and Target Agents
!

14. Agent Interaction
Results are placed in the metric: ExadataResults!
Force the agent to collect Exadata metrics
./emctl control agent runCollection
<targetName>:oracle_exadata_hc ExadataResults!
Note: <targetName> = Target in OEM12c

15. EM Output
Reports:
All Targets -> Engineered Systems -> Oracle
Engineered System Healthchecks!
!
Can be saved as CSV files
Key Areas: Summary, Incidents & Problems, Result Summary

16. EM Output
Alerts:
Default via Plug-In (15 total)
1.Verify Disk Cache Policy on DB Server!
! !2.Verify DB Server Disk Controllers use
! !writeback cache!
! !3. Verify RAID Controller Battery Condition
! !and Temperature!
! !...!
! !13. Exachk not running!
! !14. Results and Exception file(s) missing!
! !15. Metric Parsing Failed!
! !!
Note: Unwanted alerts can be disabled with monitoring templates!
