VMWare 8 connector : First stone

Hello everyone, As part of our project to update our dedicated VMware connectors, we are deploying the foundation of the VMware 8 ESX monitoring connector via REST API this month. This connector is a lightweight version, as it only includes CPU, memory, power and host discovery modes. We have already planned to enhance this connector in the coming months with new modes. It is marked as experimental because, at this stage, we still need to verify its functionality with numerous metrics (as may be the case in certain production environments). Feel free to share your feedback on this and more generally on this connector here. We will keep you informed of progress on this subject.

About Linux SNMP version 3

Dear Watchers,It had been asked for a while, we released it last December: a SNMP version 3 template is provided for Linux in our Monitoring Connectors. The documentation can be found there.I invite you to tell us here as a reply to this post, if you have feedback to give us about it.Does it fit your needs? Is it easy enough to use? Is the documentation clear?Any feedback will be great!Once we judge that the template is satisfying enough given your feedback, we’ll merge it into the Linux SNMP monitoring connector and apply the same method with other connectors.

SNClient+ : short review

Hello,I tried SNclient+ and I will share what I found with this short review.My thirst thought is that SNClient+ is mainly for Windows host.s Why ? Because I failed to installed it from Debian 5 to Debian 11 included. The Debian packages are broken on all theses releases, you can’t install it, it will throw an error.The answer from the team was if it’s not working you can try to recompile it from sources.It more sunny on the RedHat side because the RPM is valid (and tested) on RedHat 7 and 9 (I didn't test it on RH8).Also, only a unit for Systemd is included, no Init script.On the Windows side, it’s unclear on which version we could run it.I successfully run it on Windows 2019 but the SNClient+ team don’t give a list of supported OS :https://github.com/ConSol-Monitoring/snclient/issues/48 I tried some check with «check_nrpe» as I’m used to with NSClient++.Some are identical, like theses :$ /usr/lib64/nagios/plugins/check_nrpe -H 10.128.10.7 -c check_drivesize -a Drive=C: ShowAll MinWar

Retirement of Office 365 connectors within Microsoft Teams

Hello everyone,Some of you have already seen the information and have already passed it on to us (thanks again for your vigilance and your feedback). Microsoft made this announcement at the beginning of July:Starting August 15th, 2024 we will be removing the Office 365 connectors feature from Microsoft Teams. We recommend Power Automate workflows as the solution to relay information into and out of Teams in a scalable, flexible, and secure way.We will gradually roll out this change in waves:Wave 1 – effective August 15th, 2024: All new Connector creation will be blocked within all clouds Wave 2 – effective October 1st, 2024: All connectors within all clouds will stop working How will it work on the Centreon side?We have started to address this change and hope to quickly have an updated notification script in beta for users who would be interested in helping us validate it. The Centreon release of the Teams connector update is currently scheduled for the August 2024 release which will t

Does MQTT mean something to you? And Mosquitto?

Hello everyone,We started working on MQTT and more specifically Mosquitto with the aim of making a new monitoring connector for it. We already have some ideas but we would like to know if any of you are already using Mosquitto and if so for what purpose do you use it? But also your wishes regarding the monitoring of it.

What Monitoring Connectors need a SNMP version 3 template?

Dear Watchers,As I said here, we experimented a new SNMP version 3 template for Linux.We are planning to add similar SNMP version 3 templates to other monitoring connectors to make it easier to use SNMP v3 (I agree it's not ideal to use the $_SERVICEEXTRAOPTION$ macro for that) in more contexts.What I'm proposing you here is to answer to my post by giving:The name of the monitoring connector or the host template you'd like to see support SNMP v3 macros. The desired security levels (noAuthNoPriv, authNoPriv, authPriv).Then we'll prioritize the posts that will receive the highest number of "thumbs up" to deliver new templates in the monitoring connectors.Can’t wait for your suggestions!PS: If what you want is a template that do not exist yet as a monitoring connector, then please use the ideas section!PPS: Please post only one suggestion per post 🙏🏻

HTTP Collection : parse headers values

Hi, Here’s the matter : to get metrics from an API one has first to request the “login” endpoint, providing user and password, to get back an authentication token (with a limite time validity). BUT this token is provided in the header “Authorization”, not in the json body of the response, and I didn’t manage to get it.Is there a way to extract values of the header ?Thx.

SNMP Timeout dans l'UI, mais snmpget manuel fonctionne

Bonjour,Je rencontre un problème de timeout SNMP sur un switch Cisco, mais uniquement depuis l'interface de Centreon.Ce qui fonctionne :Le Ping depuis Centreon vers le switch est OK. La commande snmpget -v 2c -c MaCommunaute! IP_du_Switch .1.3.6.1.2.1.1.1.0 lancée manuellement depuis le terminal de mon poller réussit parfaitement.Ce qui échoue :Dans l'interface Centreon, après avoir configuré l'hôte avec la même IP et la même communauté, tous les services restent en UNKNOWN: SNMP Table Request: Timeout.Conclusion : La communication SNMP entre le poller et le switch est bonne, mais le moteur de Centreon semble incapable d'effectuer la requête. J'ai déjà vérifié et re-déployé la configuration de l'hôte plusieurs fois sans succès.Ma version de Centreon est la 24.04.14.Avez-vous une idée de ce qui pourrait causer ce dysfonctionnement interne ?Merci."

Memory and CPU usage of a Cisco CBS350

Hi everyone,I’m encountering an error with the centreon_cisco plugin while trying to monitor memory usage on a Cisco CBS350 switch (firmware version 3.4.0.17): UNKNOWN: Cannot find memory informationsHas anyone experienced this issue before? If so, are there known workarounds to retrieve memory metrics?Details: The plugin fails to fetch memory data via SNMP. A custom script workaround might require privilege level 15 (full admin access), which is restrictive. Questions: Is there a specific OID for memory monitoring on CBS350 switches running firmware 3.4.0.17? Are there alternative methods to monitor memory without requiring privilege level 15? Any insights, scripts, or configuration tips would be greatly appreciated!Thanks
