Nagios Support Forum

Hello Team,

Please let us know if Nagios xi is compatible with EXACS for monitoring Oracle database status , SCAN IPs, Listener Service status ,ASM monitoring ,RAC,DB monitoring etc.

If yes, can we use NCPA agent for it?
What will be the pre-requisites?

Please let us know the detailed step by step procedure to implement the same.

We are using Nagios xi 5.7.2 version.

Nagios can monitor anything that has a plugin written for it. Sometimes we'll have some default plugins you can use and other times you may need to search to find something useful.

I would initially suggest checking out the default wizards in xi:

https://assets.nagios.com/downloads/nag ... ios-xi.pdf

The SNMP wizards can be great since a lot of devices will use SNMP:

And the NCPA software can be used to do a lot of things like check services, Windows counters, system stats, etc...

If there doesn't seem to be a wizard that will work for you can try searching the exchange:

https://exchange.nagios.org

Another place to search would be github or simply searching for "<device or software name> nagios" with your favorite search engine may return a plugin that will work for you.

and finally, there's always the option to write a custom plugin:

Hello,

Will NCPA agent have any impact on ExaCS OS kernel or will the location of agent impact any DB or grid path?

We have got this query from Oracle. PFA the screenshot for your reference.

It does not make any changes to the kernel and will install to /usr/local/ncpa/ by default. Install steps and details are covered in https://www.nagios.org/ncpa/getting-started.php.

NCPA will install required packages on the system so do it on a test system first, it shouldn't touch the kernel/DB/grid path.

NCPA will install to /usr/local/ncpa, does ExaCS OS run on Oracle Linux or some other EL/Debian based system? I assume it runs Oracle Linux but you'll need to be clear on that because we do not use ExaCS or have access to it to validate if it's compatible with NCPA.

Hello,

We want to monitor from core. We understood how snmp works. We are just not sure how to write commands, host and service definitions.

Could you please provide a guide so that we can refer the same.

HI,

If you're planning to use NCPA to monitor an Oracle database, then an additional plugin will be required. The default API in NCPA contains system-level checks such as memory, disk space, CPU ...etc.

Here' are a few documentation links to help get you started.

Hope that helps and let us know if you have any other questions.
