OMC Custom Metric – empowering custom monitoring

Sometimes it is necessary to monitor specific processes that are not in the provided OMC processes list and this is where CUSTOM METRIC come into the scene.

In this short post I will show how to create a CUSTOM METRIC and ALERT RULE to manage it.

So the challenge of the day: Monitor custom windows / linux process and if it stops giving signs of life alert to the support group.

STEP 1
You will need to obtain your OCI User Information associated with your Autonomous Database (ADB) instances from the OCI Console.

Click on the user icon in top right hand corner of OCI console.
Select User Settings
On the User Details page, make a copy of the User OCID
In addition to this, make a copy of the API Key Fingerprint.

STEP 2
You will need to obtain your OCI Tenant Information associated with your Autonomous Database instances from the OCI Console.

Navigate to Administration > Tenancy Details
On the Tenancy Information page, make a Copy of the Tenancy OCID.

HINT: If OCID is hidden, you can click on Show to display entire value if you wish.

STEP 3
In another browser session, launch the OMC Console.

HINT: If the side menu does not appear, click on menu icon

STEP 4
From the side menu, navigate to:

Select Administration
Select Discovery

On the Cloud Discovery Profiles Page:
Click on + Add Profile

The Add Discovery Profile Page will appear.

Specify a Profile Name (eg. ADWPROFILE1)
Choose Cloud Service Provider Oracle Cloud Infrastructure
Click + Add
Select Region (eg. Frankfurt)
Select Services (eg. Autonomous Data Warehouse)
Enter Credential Name (eg. ADWCRED)
Enter User OCID (eg. ocid1.user.oc1.xxxxx)
Enter Tenancy OCID (eg. ocid1.tenancy.oc1.xxxxx)
Enter the associated Private key with user API Key
Enter the Fingerprint (eg. nn:nn:nn:nn:nn:nn:nn)
Click on Start Discovery

STEP 6
On the Cloud Discovery Profiles Page, wait for discovery to complete.

Click on the Job Status Count
Verify that the Service was completed successfully

This completes the setup. Now you are ready to start monitoring and managing your Autonomous Database in OMC. Click here here for more.
