Bonjour, J’ai remarqué que la découverte des Datastores étaient faites sur le Vcenter et non sur les ESX.Le problème que je rencontre est que depuis le Vcenter tous les datastores sont visibles or depuis les ESX ce n’est pas le cas. Je me retrouve donc avec des services sur mes ESX essayant de voir des datastores auxquels ils n’ont pas accès. Avez vous une solution qui permettrait de valider que l’ESX voit bien ces datastores avant de les ajouter dans les services ? Merci 

Bonjour,Existe t-il des checks, plugins spécifiques aux serveurs windows rds/tse ?

Bonjour,Je vous explique ma situation pour imager la problématique.Aujourd’hui j’aimerai que lorsqu’un host est down par exemple, qu’il envoie en journée une notification à un client (ActeurA) mais qu’à partir disons de 19h à 7h qu’il envoie au groupe astreinte (ActeurB).La problématique étant qu’aujourd’hui on peux ne pas créer de règles pour faire cela ou du moins pas à ma connaissance.

Hi,Since the NSClient++ project has been on a long break (from april 2018 and november 2023) we have never included its releases in our continuous integration processes. But since then, the project show an impressive level of activity.As we have been very busy doig a lot of other things, we have fallen far behind on this updating the base version of NSClient++ used for our builds.We’re currently trying to bridge this gap and given the wide number of changes, we may expect some regressions.Please feel welcome to use this pre-release and give us feedback here!Here are the known issues (I’ll update them as they’ll be found):The old authentication (using --legacy-password and no login) doe

Hello,Here is the context: I want to have a single dashboard view for each customer.To do this, I created a viewerclientA user with a very restricted viewerclientA ACL that only allows read access to dashboards. In addition, I shared the relevant dashboard with my admin account for the viewerclientA account, so it can access it.However, they cannot see certain widgets on the dashboard. Could you please advise me on the changes that need to be made to the ACL in order to gain access?The error message can be seen in the photo.​​​​​​  

I'm planning to buy a Midea 1 Ton Inverter AC for my bedroom (approx. 100‑120 sq ft) and wanted to get some real user feedback before making the purchase.After browsing around, I noticed some websites are offering good prices on Midea ACs, and their specs look promising. But before I decide, I have a few questions:

Hello, After upgrading from 24.04 to 25.10 we encounter an issue with centreon-engine reload.
