# 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 ; 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](/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. [](<>)
