# OracleDB monitoring with Netdata
Monitors the performance and health metrics of the Oracle database.
## Requirements
- `cx_Oracle` package.
- Oracle Client (using `cx_Oracle` requires Oracle Client libraries to be installed).
It produces following charts:
- session activity
- Session Count
- Session Limit Usage
- Logons
- disk activity
- Physical Disk Reads/Writes
- Sorts On Disk
- Full Table Scans
- database and buffer activity
- Database Wait Time Ratio
- Shared Pool Free Memory
- In-Memory Sorts Ratio
- SQL Service Response Time
- User Rollbacks
- Enqueue Timeouts
- cache
- Cache Hit Ratio
- Global Cache Blocks Events
- activities
- Activities
- wait time
- Wait Time
- tablespace
- Size
- Usage
- Usage In Percent
- allocated space
- Size
- Usage
- Usage In Percent
## prerequisite
To use the Oracle module do the following:
1. Install `cx_Oracle` package ([link](https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html)).
2. Install Oracle Client libraries
([link](https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html#install-oracle-client)).
3. Create a read-only `netdata` user with proper access to your Oracle Database Server.
Connect to your Oracle database with an administrative user and execute:
```
ALTER SESSION SET "_ORACLE_SCRIPT"=true;
CREATE USER netdata IDENTIFIED BY <PASSWORD>;
GRANT CONNECT TO netdata;
GRANT SELECT_CATALOG_ROLE TO netdata;
```
## Configuration
Edit the `python.d/oracledb.conf` configuration file using `edit-config` from the Netdata [config
directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md), which is typically at `/etc/netdata`.
```bash
cd /etc/netdata # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/oracledb.conf
```
```yaml
local:
user: 'netdata'
password: 'secret'
server: 'localhost:1521'
service: 'XE'
remote:
user: 'netdata'
password: 'secret'
server: '10.0.0.1:1521'
service: 'XE'
```
All parameters are required. Without them module will fail to start.
