Host does not appear in resource status

Good morning,We use version 22.10.4 of centreon on centos7, the collector is integrated into the server.The problem I have is this.When adding new hosts to centreon these appear well in hosts but I do not see them in the resource status.When exporting the configuration on the collector it tells me that I have 21 host while in the resource status only 19 hosts appear.I think I have to forget something but I don’t see what.If anyone has an idea I’m interested.Thanks in advance.

How to add my hosts to new host groups?

Hello,I have around 1000 VMs which I added initially into host groups like prod, preprod, uat etc. The VMs are a mix of windows and linux. Now since I will be using snmp templates and some will use linux_snmp and some will use windows_snmp templates, I want to create 2 new host groups - windows and linux. Now I want to add my hosts into these host groups. What would be the easiest way to do it please? via csv import for example. How to add my already added hosts to these new groups without impacting the existing hosts or host groups. For example, I cannot delete and readd all hosts with updated host groups. I dont have autodiscovery license.

snmpwalk

Hello. I am running snmpwalk extend ('NET-SNMP-EXTEND-MIB::nsExtendOutLine. "ExtendName"). CENTREON reports OK status because snmpwalk is working correctly. However, I need the exitcode of the exend in CENTREON. Alternatively, I need to determine the status of the extension and display the correct status in CENTREON. Thank you for your help.

Centreon Linux Hosts Autodiscovery - Nothing but SNMP ?

Hi,Centreon provides automatic hosts discovery with the centreon-plugin-Operatingsystems-Linux-Snmp.noarch package (For On-Prem servers).On the Central you need to install centreon-pack-operatingsystems-linux-snmp-23.09.2-1.el8.noarchBut in  our compagny: SNMP is disabled everywhere. My question is : is there any other way than SNMP to automatically discover linux hosts ?I couldn’t find such connector (with discovery feature) in the centreon documentations … Thanks a lot

Ordering custom filters

Hi,Although it has been reported many versions ago it is still not possible (in 22.10.19) to re-order custom filters in the Resource Status page. May we expect this to be fixed someday?To be precise, it is indeed possible to re-order the custom filters with a simple drag-n-drop but when the page is reloaded the filters get back to their original order (ie: the order in which they have been created).Can’t tell for everyone but that’s the kind of little thing that is of real annoyance in everyday use.

SNMP TRAP is pending until trap is sent

I don't know if this is normal, but the services to which SNMP traps are connected remain pending until the traps are sent from the device. I have triggered the traps manually. After that everything works perfectly, the services go into the critical state and then into the OK state and stay there until a trap is sent again.

Printer Standard Plugin Pack

Greetings everyone,i have a strange problem in which i cannot solve, perhaps someone can point in right direction.I'm using the plugin pack for printer standard rfc3805, however, its reporting opposite and doesn't seem to follow the warning/critical thresholds.for example, i have known color printer with black toner at 16%, critical threshold is any number above 16% - it reports back as “OK”,when i change the critical threshold to any number below 16% - it reports as “critical”also i have magenta toner at 82%, same scenario, i play with the thresholds, any number above 82% reports as “critical” any number below 82% reports as “OK”i was able to reproduce this with any snmp printer on my network, its reporting opposite.What gives? any known bugs with this python plugin ?my centos7 box is all up to date, centreon is at latest version and plugins are up to date etc.Attached is a screenshot.

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?

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
