Oracle by Zabbix agent 2

Overview

For Zabbix version: 6.2 and higher
The template is developed for monitoring DBMS Oracle Database single instance via Zabbix agent 2.

This template was tested on:

  • Oracle Database, version 12c2, 18c, 19c

Setup

See Zabbix template operation for basic instructions.

  1. Setup and configure zabbix-agent2 compiled with the Oracle monitoring plugin.
  2. Set the {$ORACLE.CONNSTRING} such as <protocol(host:port)> or named session.
  3. Set the user name and password in host macros ({$ORACLE.USER}, {$ORACLE.PASSWORD}, {$ORACLE.SERVICE}) if you want to override parameters from the Zabbix agent configuration file.

Test availability: zabbix_get -s oracle-host -k oracle.ping["{$ORACLE.CONNSTRING}","{$ORACLE.USER}","{$ORACLE.PASSWORD}","{$ORACLE.SERVICE}"]

Zabbix configuration

No specific Zabbix configuration is required.

 DEPENDENT oracle.session_long_time_locked

Preprocessing:

Oracle Oracle: Sessions concurrency

The percentage of concurrency. Concurrency is a DB behavior when different transactions request to change the same resource - in case of modifying data transactions sequentially block temporarily the right to change data, the rest of the transactions are waiting for access. In the case when access for resource is locked for a long time, then the concurrency grows (like the transaction queue) and this often has an extremely negative impact on performance. A high contention value does not indicate the root cause of the problem, but is a signal to search for it.

Oracle: Too many sessions locked

Number of sessions locked over {$ORACLE.SESSION.LOCK.MAX.TIME} seconds is too high. Long-term locks can negatively affect database performance, therefore, if they are detected, you should first find the most difficult queries from the database point of view and analyze possible resource leaks.

Oracle: Too high database concurrency

Concurrency rate is over {$ORACLE.CONCURRENCY.MAX.WARN}%. A high contention value does not indicate the root cause of the problem, but is a signal to search for it. In the case of high competition, an analysis of resource consumption should be carried out, the most "heavy" queries made in the database, possibly - session tracing. All this will help determine the root cause and possible optimization points both in the database configuration and in the logic of building queries of the application itself.
