No monitroring connectors found centreon

hello

what centreon version are you using and can you screenshot the status in 

Administration / Extension / manager

it should look like that

​@christophe.niel-ACT  this is what it looks like 

I’m currenlty on centreon 24.04.1

well, you seem to be missing the licence (free) for your installation

if you reinstalled or changed the OS there is a serial that fix your licence, you would need to ask for a new one on the centreon website

if you never had a free licence, you would need to ask for one here:

Set up your free IT-100 solution | Centreon Documentation 

​@christophe.niel-ACT but it says its just a free trial, and is that really the cause? it has nothing to do with proxy? also I have an older centreon solution that works perfeclty fine but its not me who set it up, would I need a different license than the one used in that older solution?

because that license seems to be just for “auto discovery” does that have anything to do with the catalogue for the packs?

IT-100 licence is free and no expiration date, it’s free up to 100 host and gives you access to all monitor connector, you just need to register

​@christophe.niel-ACT I have more than 100 hosts but as i said earlier that license seems to be just for “auto discovery” does that have anything to do with the catalogue for the packs? 

autodiscovery is included in the monitoring packs

if you have more that 100 host you need to contact centreon sales, which outside my scope :)

​@christophe.niel-ACT Is there a way to install those plugins manually if we cant obtain a license? or only way to use packs is through licensing?

hello

you can effectively install all the plugin from the git, simply git clone the centreon-plugin repository

HOWEVER : this will only install the executable (perl) commands, this will not install the configuration and template in the Web UI, that is what the monitoring connector is for (and what you pay for basically), and maybe in some case some dependencies

you can also use the command pre-packaged (and their dependencies) with ‘yum/apt install centreon-plugin-???’ from the public repository, but that will also only install the commands, but at least the command name is the same as in the plugin documentation (and the package name is in the plugin doc)

in both case you will need to create your own “check command”, “service template” and “host template”, this is oldschool centreon 

this needs a bit of knowledge on how to create command with “macro”, and where to set the macro on the service and host template, but it is doable (hard and long if you want lots of plugin)

​@christophe.niel-ACT so if i git clone it and although my machine has restricted internet access after cloning then i will still see them when im configuring commands right? also i’m seeing two different locations for the plugins one /nagios/plugins and one /centreon/plugins, and as for the centreon_plugins.pl when i try to run it it says Can't locate centreon/plugins/script.pm in @INC (you may need to install the centreon::plugins::script module) does that mean it will work when i clone the git? or is that an entirely different issue? because so far i’m seeing this error in the logs

this is all confusing me 

hello

if you don’t understand the concept of working with the git clone, don’t work with the git clone, it takes practice and undestanfing of centreon (and other linux component) to be able to work with that.

this way outside the scope of thing I can explain here, and you would need to read a lot of documentation.

you need https connection to internet, and you need dns resolution, and you need to use the package from the repository, they will install the correct commands and their packages.

(without internet you will have problems, there are workarounds, but that’s highly technical, like installing a linux repository server, again way outside the scope of centreon)

here is an example : 

Fortinet Fortigate | Centreon Documentation go to the section “installing the connector”

you have “Pack” which is the thing with licence

and you have “plugin” which is the command you can install from the repository for free

you have the command to copy/paste

then below that section you get the command to test if it is working

there you can see were the plugin was installed (/usr/lib/centreon/plugins/….)

and again, if creating template or using command and macro is confusing and you don’t know how, you will need to read a lot of documentation (or simply contact a pre-sale from centreon to explain your need and how to work with your limited internet connexion, and benefit from the all the simplicitiy of using the “connectors)

here the entry point of the doc for how to monitor thing with centreon Basic principles of monitoring | Centreon Documentation

on the left section you get “how to monitor a host manually”, a service manually

and here is where you create commands and macro

Commands | Centreon Documentation

and lots of concept to understand here
