Nagios Support Forum

You might try following the official documentation:
https://assets.nagios.com/downloads/nag ... _Agent.pdf

Here's some that includes the stock Nagios plugins as well:
https://assets.nagios.com/downloads/nag ... ios-XI.pdf

I realize the title says "Nagios XI", but much of the same steps are valid for Nagios Core.

Thanks @mcapra!

He's right, try following our official documentation if you're going to monitor 100 Linux servers.
It should work just fine, but if not you could create another thread.

Glad to hear it's working though! Do you have any more questions or can we close this thread?

@mcapra

I tried to follow the steps mentioned in the Knowledge Base Article.

But getting the below Error:
[trathi@xxxxxxx nrpe-3.2.1]$ sudo make install
cd ./src/; make install

make install-plugin

Please Suggest what to do?

@amitgupta19,

Are you only trying to download the plugin? What OS are you downloading NRPE on?

Did you download the Prerequisites?

I am trying to monitor the remote system which is installed with "Oracle Linux".

Can you tell me that do i need to install the following as per the links in the previous reply from mcapra.
1) Install the NRPE Agent.
2) Install the Nagios Plugin.

Is the above 2 sufficient to monitor the Linux Server?

Yes, if you wanted to use the Nagios Plugins with the NRPE agent to monitor Oracle Linux.

Here's the guide for installing NRPE on Oracle Linux.
https://support.nagios.com/kb/article.p ... acle_Linux

i am able to install the Nagios Plugin Successfully

But when i try to install the NRPE it is giving the following Error:

[XXXXX@labwlap1 nrpe-3.2.1]$ sudo make install

It looks like you may have missed the make all step. Follow https://support.nagios.com/kb/article.p ... acle_Linux again making sure run all of the commands in the order listed.

I have run the commands in the same order as mentioned in the URL.

Please find attached the command list along with the error.

That appears to have worked. No errors are seen this time when the sudo make install command was run.
