Best way to monitor a Windows server

Hello,We are currently monitoring our Windows servers using NRPE (without SSL).In your opinion, what is the most secure and reliable way to monitor Windows systems, while still getting detailed metrics like those provided by NRPE?Would you recommend NRPE with SSL, WMI, or another method?Thank you for your feedback.

Lua Stream Connector Debug: filter returned false / Events not being processed on specific host

Hello Centreon Community/Support,I am experiencing an issue with a custom Lua stream connector script that is designed to send monitoring events to an external system (BEM). The script functions correctly on one Centreon Poller/Central server, but on a different host (which I'll refer to as "Problem Host"), events are consistently being dropped at the filter stage, resulting in the debug log message filter' returned false.I have confirmed that the target system is listening on the expected port (2540) and that the "Problem Host" can establish a TCP connection to it.Problem Description:On a specific Centreon host (the "Problem Host"), the Centreon Broker Lua stream connector is not processing events as expected. The debug logs show that the filter function in the Lua script is rejecting all incoming service status and host status events, even though the same script works perfectly on another Centreon host. This prevents any alarm messages from being sent to the BEM system.Observed Debug

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."
