Step 1: NRPE Linux Agent Installation
Install nrpe agent on Target database server. Make sure that all ‘oracle’ related plugins are available in ‘
/usr/local/nagios/libexec’ directory. Otherwise, download them from Nagios Exchange.
Step 2: Oracle Instant Client Installation
Create an account on ‘www.oracle.com’, navigate to ‘Downloads’ -> ‘Oracle Instant Client’. Select the proper OS version and architecture (say, Linux x86_64). Download the following files and store them in ‘
Step 3: Download & Execute the Oracle Install Script
NOTE: Make sure that the Nagios Monitoring Server is connected to internet, as the script will try to download some Perl modules through CPAN.
sudo reboot cd /tmp wget http://assets.nagios.com/downloads/general/scripts/oracleinstall.sh chmod +x oracleinstall.sh ./oracleinstall.sh
In the end, it will display two variables, which must be saved somewhere as they will be needed later on:
Step 4: Replacing the Variables
In Nagios XI web interface, navigate to ‘Configure’ -> ‘Core Config Manager’ -> ‘Commands’.
Search for the following commands:
LD_LIBRARY_PATHvariables with the values provided by
Using any Oracle Wizard, start monitoring Oracle database server.
Install DBD::Oracle Module through CPAN as follows:
While installing above module, following error might come:
export ORACLE_HOME=<path to your Oracle which was given by the script> export LD_LIBRARY_PATH=$ORACLE_HOME/lib cpan -i DBD::Oracle
Installing on a linux, Ver#2.6 Using Oracle in /usr/lib/oracle/12.1/client64 DEFINE _SQLPLUS_RELEASE = "1201000200" (CHAR) Oracle version 126.96.36.199 (12.1) Unable to locate an oracle.mk or other suitable *.mk file in your Oracle installation. (I looked in /usr/lib/oracle/12.1/client64/rdbms/demo/demo_xe.mk /usr/lib/oracle/12.1/client64/rdbms/lib/oracle.mk /usr/lib/oracle/12.1/client64/rdbms/demo/oracle.mk /usr/lib/oracle/12.1/client64/rdbms/demo/demo_rdbms.mk /usr/lib/oracle/12.1/client64/rdbms/demo/demo_rdbms64.mk /usr/lib/oracle/12.1/client64/rdbms/lib/ins_rdbms.mk /usr/share/oracle/12.1/client64/demo.mk under /usr/lib/oracle/12.1/client64) The oracle.mk (or demo_rdbms.mk) file is part of the Oracle RDBMS product. You need to build DBD::Oracle on a system which has one of these Oracle components installed. (Other *.mk files such as the env_*.mk files will not work.) Alternatively you can use Oracle Instant Client. In the unlikely event that a suitable *.mk file is installed somewhere non-standard you can specify where it is using the -m option: perl Makefile.PL -m /path/to/your.mk See the appropriate README file for your OS for more information and some alternatives. at Makefile.PL line 1187.
