Adding new poller (version 22.04.20-1) with RHEL 8

I have working setup of Central and Poller both using 22.04.5-1 version on CentOS7.I'm trying to add new poller with 22.04 version but on RHEL 8.Followed this documentation - https://docs.centreon.com/docs/22.04/installation/installation-of-a-poller/using-packages/ But on new Poller will RHEL 8 - I see centreon version as centreon-poller-22.04.20-1.el8.noarch. All services are running on poller but on Central poller configuration it showing "Is running ? as NO". So, question is central with version "22.04.5-1" will not work with poller version "22.04.20-1"?do they need to be "exactly" the same?

Interpretation HTML dans l'output

Bonjour à tous,Mon client a un script custom qui à un output en texte avec des balises HTML.Dans la génération précédente de Centreon, on modifiait le escape_html_tags dans Cgi.cfg et cela fonctionnait. L’output de Centreon interprétait les balises HTML correctement ( gras, retour à la ligne, etc..).Dans Centreon 23.10, il n’y a plus de cgi.cfg.. et donc un output HTML qui n’est pas compris.Avez vous une idée pour résoudre le problème?

check snmp printer

Greetings everyone,i have a strange problem in which i cannot solve, perhaps someone can point in right direction.I’m polling my printer thru snmp with “consum test” command to see whats available to poll:screenshot below shows I’m able to poll listed items such as black toner:my next item i want to poll are the drum status, so:printer or centreon doesn't like the string “Drum Cartridge (R1)”but its listed as that just like Black Toner.However, this string with backslashes works via command line:My problem really is the above command with the backslashes only works with command line, when doing this command via the GUI, it doesn't work, I’m finding the GUI is stripping the backslashes… has anyone come across this or know of a solution/workaround ??

customized notification not working

Dear community,I’m asking your help. I try to create a new customized notification connector. At this moment I’m pretty sure the command is properly formated.However, Never I’ve received a notification sent using this connector.From “Notification side”, here is what I’ve configured.host notifyservice notifyHere is what is logged within centreon-engine.loglog centreon-engine(No output return from plugin is just because of the connection unavailable, as everytime I want the system to use this connector, I cut the network connection within the virtual machine. Therefore Centreon is unable to communicate with the agent).The more strange that I’m unable to understand and go further is “Error: can't execute service notification 'astreinte_tel' : missing separator '''”The user ‘astreinte_tel’ is the one who should use the connectors… Note: I’ve tried to enable debug logs, but don’t know why the current system is unable to keep my settings, therefore nothing is filled in centengine.debug. I ho

Getting downtimes from the API v2

Hello,I’m getting downtimes using API v2 without problems. I need to filter those downtimes that are really actives, specifically those you can see at ‘Downtimes’ page in the Centreon interface. However, from the API I get many more than the ones I see at ‘Downtimes’ page. How can I get the same result? Which filter do I have to use?I thought the active ones were those with ‘deletion_time’ to NULL or ‘actual_end_time‘ to NULL, but the are a lot with these values that don’yt appear on the interface. So I don’t know how to get the ‘real’ ones.Can you help me?Thanks in advance.Albert

Which proptocol do you use to monitor your Linux hosts ?

Hi,To monitor our Linux Hosts, we are using the agent nrpe :We are using the check_nrpe (Version: 4.0.3) on the Pollers Side, and the old nrpe agent binary  (Hosts side).These binaries are issued from a ‘nagios’ git… (hard to maintain - compiled ...etc)We would like to use a more standard “centreon” oriented and supported method (with regular updates). An alternative could be to use this Agentless ssh method :https://docs.centreon.com/pp/integrations/plugin-packs/procedures/operatingsystems-linux-ssh/Also centreon mention nrpe3:https://docs.centreon.com/pp/integrations/plugin-packs/procedures/operatingsystems-linux-snmpv3/… but it seems that the needed packages are not provided any more with version 23.XX (Example : centreon-nrpe3-daemon.x86_64) Also snmp exists but it is not our prefered solution. From you point of view : What is the best recommended standard method by centreon ??Which method is the most used ? Do you think using ssh could lead to potential security risks ??Thanks a l

BUG: Centreon retrieves two states for one interface

I try to monitor interface 1 of an Aruba-Switch-1930. The command which I use is the following:/usr/lib/centreon/plugins//centreon_aruba.pl--plugin=network::aruba::standard::snmp::plugin--mode=interfaces--hostname=10.133.120.240--snmp-version='3'--snmp-community='public'--snmp-username=admin03--authpassphrase="my password"--authprotocol=SHA--privpassphrase="my password"--privprotocol=DES--interface='^1$'--name--add-status--add-traffic--warning-in-traffic='80'--critical-in-traffic='90'--warning-out-traffic='80'--critical-out-traffic='90'--verboseI replaced the authpassphrase and the privpassphrase. The problem with this command is that it returns the following output:There are two states for the same interface. The first one mentioned (Interface ‘1’ Status : up (admin: up) is the right one. However, Centreon uses the second output (Interface: down). How could i change it to make this right? For all other interfaces it functions perfectly.

Submiting result to a service

Hi,To submit a result to a service with the HTTP REST API, as described in https://docs-api.centreon.com/api/centreon-web/22.10/#tag/Submit/paths/~1monitoring~1hosts~1%7Bhost_id%7D~1services~1%7Bservice_id%7D~1submit/postdoes the service have to be a passive service? Or is it possible to submit a result for an active service?Is the REST API the preferred way of doing that? Or NSCP still is the more obvious choice? Is this part of the REST API considered stable? In 22.10? In 23.10?

UNKNOWN: No entry found (maybe you should reload cache file)

Hello Centreon Slack!I'm on version 22.10.On the Centreon Web interface I have several services in this status. They were configured using cisco_standard template from the plugin packs and are monitoring Traffic Global with a filter for each specific interface.This were created using the discovery feature and started having this issue a short time after the plugin pack license expired but there are other services created in a similiar way still working.I have already cleared the cache files from /var/lib/centreon/centplugins and permissions in that folder set to centreon and centengine. It is also not a storage issue in the server and executing the command through terminal returns the exact same output Thanks in advance
