Install & configure NRDOT for Oracle monitoring with Self-hosted PDB

Install NRDOT Collector

Select the appropriate installation distribution method for your Linux environment:

Configure database user

Create a monitoring user with the necessary privileges for your PDB Oracle Database instance.

1. Run the following statement as SYS before creating the user or running any grants:

   ALTER SESSION SET CONTAINER = "<YOUR_PDB>";

   Copier
2. Run the following statements as SYS inside your target PDB to create a local monitoring user:

   CREATE USER <YOUR_DB_USERNAME> IDENTIFIED BY "<YOUR_DB_PASSWORD>";
   GRANT CREATE SESSION TO <YOUR_DB_USERNAME>;

   Copier

Grant monitoring privileges for your PDB

Run these commands as the SYS user inside your PDB. This gives the monitoring tool the basic access it needs to collect metrics, track events, and find your database instances.

Configure NRDOT Collector

Configure the NRDOT Collector with your PDB-specific settings.

1. Create the configuration file. The filename must be oracle-config.yaml.

   bash

   Copier

   $
   sudo nano /etc/nrdot-collector/oracle-config.yaml

2. Add the configuration content below to the oracle-config.yaml file you created in the previous step:

3. Under the Events section, enable these event types to collect their metrics:

   Event	Description
   db.server.query_sample	Per-session active query samples capturing current SQL, wait state, and blocking details.
   db.server.top_query	Top N SQL statements by CPU or elapsed time, including execution stats and query plans.
   db.server.session.wait_sample	Per-session cumulative wait counts and durations from v$session_event.
   db.server.top_procedure	Top N stored procedures ranked by resource usage, including execution stats.
   db.server.query_plan	Execution plan details for top and sampled queries.

4. Configure the collection settings for each event type:

   Configuration section	Parameter	Value
   top_query_collection	max_query_sample_count	1000
   top_query_collection	top_query_count	200
   top_query_collection	collection_interval	60s

Update NRDOT Collector configuration

Update the NRDOT Collector configuration to use your oracle-config.yaml file:

$
sudo sed -i 's|OTELCOL_OPTIONS="--config=/etc/nrdot-collector/config.yaml"|OTELCOL_OPTIONS="--config=/etc/nrdot-collector/oracle-config.yaml"|' /etc/nrdot-collector/nrdot-collector.conf

Restart NRDOT Collector

After updating your configuration, restart the NRDOT Collector:

$
sudo systemctl restart nrdot-collector.service
$
sudo systemctl status nrdot-collector.service

Find and use your data

Once your data is being collected, you can access comprehensive Oracle Database monitoring through the New Relic UI.

To find your Oracle Database entity in New Relic:

1. Go to https://one.newrelic.com > All Capabilities > Databases.
2. Set the search criteria as instrumentation.provider = opentelemetry.
3. Select your Oracle Database from the list of entities.
