# Setting Up Database Monitoring for Oracle Autonomous Database

Database Monitoring provides deep visibility into your Oracle databases by exposing query samples to profile your different workloads and diagnose issues.

The Agent collects telemetry directly from the database by logging in as a read-only user.

## Before you begin{% #before-you-begin %}

{% dl %}

{% dt %}
Supported Oracle versions
{% /dt %}

{% dd %}
11g, 12c, 18c, 19c, 21c
{% /dd %}

{% dt %}
Supported Agent version
{% /dt %}

{% dd %}
7.53.0+
{% /dd %}

{% dt %}
Performance impact
{% /dt %}

{% dd %}
The default Agent configuration for Database Monitoring is conservative, but you can adjust settings such as the collection interval and query sampling rate to better suit your needs. For most workloads, the Agent represents less than one percent of query execution time on the database and less than one percent of CPU.Database Monitoring runs as an integration on top of the base Agent ([see benchmarks](https://docs.datadoghq.com/database_monitoring/agent_integration_overhead/?tab=oracle)).
{% /dd %}

{% dt %}
Proxies, load balancers, and connection poolers
{% /dt %}

{% dd %}
The Agent must connect directly to the host being monitored. The Agent should not connect to the database through a proxy, load balancer, or connection pooler. Each Agent must have knowledge of the underlying hostname and should stick to a single host for its lifetime, even in cases of failover. If the Datadog Agent connects to different hosts while it is running, the values of metrics will be incorrect.

Data security considerations
{% /dt %}

{% dd %}
See [Sensitive information](https://docs.datadoghq.com/database_monitoring/data_collected/#sensitive-information) for information about what data the Agent collects from your databases and how to ensure it is secure.

## Setup{% #setup %}

Complete the following to enable Database Monitoring with your Oracle database:

1. Create the Datadog user
1. Grant the user access to the database
1. Install the Agent
1. Configure the Agent
1. Install or verify the Oracle integration
1. Validate the setup

### Create the Datadog user{% #create-the-datadog-user %}

If you already have the legacy Oracle integration installed, the user already exists, and you can skip this step.

Create a read-only login to connect to your server and grant the required permissions:

```SQL
CREATE USER datadog IDENTIFIED BY <YOUR_PASSWORD>;
```

### Grant the user access to the database{% #grant-the-user-access-to-the-database %}

```SQL
grant create session to datadog ;
grant select on v$session to datadog ;
grant select on v$database to datadog ;
grant select on v$containers to datadog;
grant select on v$sqlstats to datadog ;
grant select on v$instance to datadog ;
grant select on dba_feature_usage_statistics to datadog ;
grant select on V$SQL_PLAN_STATISTICS_ALL to datadog ;
grant select on V$PROCESS to datadog ;
grant select on V$SESSION to datadog ;
grant select on V$CON_SYSMETRIC to datadog ;
grant select on CDB_TABLESPACE_USAGE_METRICS to datadog ;
grant select on CDB_TABLESPACES to datadog ;
grant select on V$SQLCOMMAND to datadog ;
grant select on V$DATAFILE to datadog ;
grant select on V$SYSMETRIC to datadog ;
grant select on V$SGAINFO to datadog ;
grant select on V$PDBS to datadog ;
grant select on CDB_SERVICES to datadog ;
grant select on V$OSSTAT to datadog ;
grant select on V$PARAMETER to datadog ;
grant select on V$SQLSTATS to datadog ;
grant select on V$CONTAINERS to datadog ;
grant select on V$SQL_PLAN_STATISTICS_ALL to datadog ;
grant select on V$SQL to datadog ;
grant select on V$PGASTAT to datadog ;
grant select on v$asm_diskgroup to datadog ;
grant select on v$rsrcmgrmetric to datadog ;
grant select on v$dataguard_config to datadog ;
grant select on v$dataguard_stats to datadog ;
grant select on v$transaction to datadog;
grant select on v$locked_object to datadog;
grant select on dba_objects to datadog;
grant select on cdb_data_files to datadog;
grant select on dba_data_files to datadog;
```

### Securely store your password{% #securely-store-your-password %}

Store your password using secret management software such as [Vault](https://www.vaultproject.io/). You can then reference this password as `ENC[<SECRET_NAME>]` in your Agent configuration files: for example, `ENC[datadog_user_database_password]`. See [Secrets Management](https://docs.datadoghq.com/agent/configuration/secrets-management/) for more information.

The examples on this page use `datadog_user_database_password` to refer to the name of the secret where your password is stored. It is possible to reference your password in plain text, but this is not recommended.

### Install the Agent{% #install-the-agent %}

See the [DBM Setup Architecture](https://docs.datadoghq.com/database_monitoring/architecture/) documentation to determine where to install the Agent. The Agent doesn't require any external Oracle clients.

For installation steps, see the [Agent installation instructions](https://app.datadoghq.com/account/settings/agent/latest).

### Configure the Agent{% #configure-the-agent %}

Download the wallet zip file from the Oracle Cloud and unzip it.

Create the Oracle Agent conf file `/etc/datadog-agent/conf.d/oracle.d/conf.yaml`. See the [sample conf file](https://github.com/DataDog/datadog-agent/blob/main/cmd/agent/dist/conf.d/oracle.d/conf.yaml.example) for all available configuration options.

**Note:** The configuration subdirectory for the Agent releases between `7.50.1` and `7.53.0` is `oracle-dbm.d`. See [Configuring the Oracle Integration on Agent 7.50.1+](https://docs.datadoghq.com/integrations/guide/oracle-check-upgrade-7.50.1/) for more details.

Set the `protocol` and `wallet` configuration parameters.

```yaml
init_config:
instances:
  - server: '<HOST_1>:<PORT>'
    service_name: "<SERVICE_NAME>" # The Oracle CDB service name
    username: 'datadog'
    password: 'ENC[datadog_user_database_password]'
    protocol: TCPS
    wallet: <YOUR_WALLET_DIRECTORY>
    dbm: true
    tags:  # Optional
      - 'service:<CUSTOM_SERVICE>'
      - 'env:<CUSTOM_ENV>'
  - server: '<HOST_2>:<PORT>'
    service_name: "<SERVICE_NAME>" # The Oracle CDB service name
    username: 'datadog'
    password: 'ENC[datadog_user_database_password]'
    protocol: TCPS
    wallet: <YOUR_WALLET_DIRECTORY>
    dbm: true
    tags:  # Optional
      - 'service:<CUSTOM_SERVICE>'
      - 'env:<CUSTOM_ENV>'
```

After all Agent configuration is complete, [restart the Datadog Agent](https://docs.datadoghq.com/agent/configuration/agent-commands/#start-stop-and-restart-the-agent).

### Validate the setup{% #validate-the-setup %}

[Run the Agent's status subcommand](https://docs.datadoghq.com/agent/configuration/agent-commands/#agent-status-and-information) and look for `oracle` under the **Checks** section. Navigate to the [DBM Oracle Database Overview](https://app.datadoghq.com/dash/integration/30990/dbm-oracle-database-overview) dashboard and [Databases](https://app.datadoghq.com/databases) page in Datadog to get started.

## Custom queries{% #custom-queries %}

Database Monitoring supports custom queries for Oracle databases. See the [conf.yaml.example](https://docs.datadoghq.com/database_monitoring/architecture/) to learn more about the configuration options available.

{% alert level="danger" %}
Running custom queries may result in additional costs or fees assessed by Oracle.
{% /alert %}
