check_nrpe compatibility with older Linux OS and nrpe clients

Hello,When upgrading to centreon 20.10 (from an old 2.4.4), i noticed that check_nrpe (4.0.0) wasn’t compatible with older Linux OS having older nrpe clients.So i kept using the check_nrpe from the previous centreon and it works well.Now, i am looking to update to centreon 22.10 but i know i will have the same issue.The backward compatible options aren’t working.The error is still “CHECK_NRPE: (ssl_err != 5) Error - Could not complete SSL handshake wit <IP>” and here’s the log from a nrpe client 2.15 with debug on :nrpe[4852]: Connection from 10.5.236.21 port 2742nrpe[4852]: Host address is in allowed_hostsnrpe[4852]: Handling the connection...nrpe[4852]: Error: Could not complete SSL handshake. 1nrpe[4852]: Connection from ⚌⚌#027q closed Here’s was i have tested so far : (check_nrpe 4.1.0 was compiled from sources)check_nrpe from versions 4.*, when not working with older nrpe client, were tried with various options as -2, -3 & -L ALLHow are we supposed to monitor old OS with

Aucun graphique sur CENTREON

Bonjour,  J’avais déjà monté un serveur CENTREON, tout fonctionnait très bien. Je suis reparti de 0 pour une installation propre. Pour cela, j’ai récupérer mes anciennes commandes de tests pour lesquels j’avais des graphiques, et là je n’en ai plus aucun… Je n’ai pas de fichiers RDD sur mon serveur… J’ai fait quelques premières vérifications et tout à l’air bon. Je désespère de trouver une solution… Cordialement, Florian

Size of the widget displaying FQDN/IP adress

Hi,Why this widget has a full width?: Half the width would be enough, as for Timezone and Current status duration. Is that not a waste of space?I know a DNS name may be longer but it’s also the case for the host alias, still it uses half the width like the Timezone.

Reporting::Get a list of plugins installed but NEVER used

Is there a way, in a EPP-licenced version (or the limited free version), to know which installed plugins are UNUSED?Is there also a way to find a list of all USED plugins?Looking for any hint!What I’m exploring:I’m guessing it may be useful to check the Databases; the config database “centreon” or the information related to performance data in the “centreon_storage” database. But I don’t yet know if any table holds information on plugins.Or maybe their is a simple RestAPI or CLAPI query that could provide information close to what I’m looking for? A strategy I’m exploring is finding host/services templates that are used using CLAPI, then finding their associated plugins via some other requests: # Host templatescentreon -a admin -p password -e |grep "HOST;addtemplate"# Service templatescentreon -a admin -p password -e |grep "SERVICE;ADD"   Or maybe start by listing the content of all installed plugin packages, the look for the templates, and checks usage at other places:  repoquery --in

Resources Status page: search for a string with a space character

Hi,The new Resource Status page use regexp, while this is a good enhancement, it doesn’t permit to search for a string with a space in it. I tried quoting the string (both simple and double), I also tried to use `\s`, none of this works.How can I achieve that?This is something the Monitoring/Services and Monitoring/Hosts pages permit. It’s useful when searching in the plugin output (or even sometimes in the service name).I’m OK to do my best to start using this new Resource Status page (and, to incite my users to do so) but I’d like to have the same functionalities I had with the old ones.

Reopenning of bug in Github made impossible

Hi,The following bug has been closed and I cannot manage to reopen it.It’s not fixed, and even for the « workaround » suggested (which is: using the new Resources Status page) the person who closed the bug didn’t even read correctly what I wrote, he’s telling me to try something I already told wasn’t working.Why is it not possible to reopen a bug? The functionality exists in Github so why does it seems to have been deactivated?Best regards,

Conserve line returns in comment

Hi,The comment added when one put a downtime on an object is displayed in the tooltip when you rollover the downtime logo (the pink triangle with an exclamation mark).The problem is that line returns aren’t displayed there. The only workaround is to directly write the comment as HTML (ie: with <br /> tags), but that’s not convenient for the average user (nor is for the advanced one in fact…). They are saved in database, they probably should be replaced with an HTML tag for display, or in a HTML container that display text raw. What do you think?More globally, I hope the developer team still has time to enhance the “old” UI, is this the case?I personally think the new UI is unfinished for a good part, so the idea to depreciate the old one so rapidly really is a bad idea. Currently this is the new UI that should be warned as beta, and be optional for the user to test, not the (fully functional) current one marked as depreciated ! 😊 I wonder what other people think?

help with developping a plugin : how to use threshold with custom perddata

HelloI launched myself in the full rebuild of an snmp plugin for huawei dorado (san storage) by using Rest API.I did this because I added a “lun” mode to the existing snmp plugin, but as it happens, if you have too many luns the snmp is getting lots timeout, the table is huge and when go over 50 lun/snapshot the plugin never give the information back… after a bit of digging, I found there is a Restful api, and lot more digging I managed to create my own custom api I have an issue with the thing I coded, I cannot get critical or warning alerts when I use for example “--critical-usage-prct=50” on the perfdatahere is the plugin, work in progress : centreon-plugins/luns.pm at master · christophe-activiumid/centreon-plugins (github.com) (btw, anyone feel free to test it in command line if you have a dorado, it needs a read only account, and work for dorado v6 and v5)everything work fine, except threshold...I do need to implement a cache/statefile on this specific lun mode because with the a

Installation of the Centreon plugins from the Github repository

Hi,When looking in the centreon/centreon-plugins Github repository I can’t see the same files which I have in the /usr/lib/centreon/plugins/ directory after an installation from the RPM packages.My knowledge of Perl is very limited, but I suppose there is some kind of install process in order to be able to use the plugins. I looked at the README but didn’t find any. I don’t think that just cloning the repository would permit me to use the plugins, but maybe I’m wrong? If so, how to use them?I’d like to be able to do that in order to test the very last version of the plugins without having to wait for release and packaging.I suppose I’d have to do so if I’d like to participate in the development of the plugins. The README, in the  Basic Usage section, shows an example with running the “centreon_plugins.pl” script. Would it work just after I cloned the repository? I didn’t try because the README also tells : “I have finished the install section and I want to monitor a Linux in SNMP”, so
