### prerequisite
|
|
|
|
To use the Oracle module do the following:
|
|
|
|
1. Install `cx_Oracle` package ([link](https://cx-oracle.readthedocs.io/en/latest/installation.html#install-cx-oracle)).
|
|
|
|
2. Install Oracle Client libraries ([link](https://cx-oracle.readthedocs.io/en/latest/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
|
|
|
|
```yaml
|
|
local:
|
|
user: 'netdata'
|
|
password: 'secret'
|
|
server: 'localhost:1521'
|
|
service: 'XE'
|
|
|
|
remote:
|
|
user: 'netdata'
|
|
password: 'secret'
|
|
server: '10.0.0.1:1521'
|
|
service: 'XE'
|
|
```
|
|
|
