Centreon Infra Monitoring

Hi,I need your help. I’ve installed centreon map, everything seems OK but I got a timeout error when I’d like to access to supervision → MAP on central server :on centreon-map serveur, diagnostic is ok (I’m using http access) :########## Centreon Map server version ##########  [INFO] centreon-map-engine-22.10.15-1.el8.noarch########## System ##########  [OK]   SELinux disabled  [OK]   Firewall is disabled  [INFO] Physical memory available on the server: 7836804 kb.  [INFO] Number of CPU available on the server: 4 core(s)########## Java ##########  [OK]   Java 17 installed  [OK]   Optimization found for JVM: JAVA_OPTS="-Xms512m -Xmx4G -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/centreon-map -Dmanagement.endpoints.enabled-by-default=false -Dmanagement.endpoint.health.enabled=true -Dmanagement.endpoint.metrics.enabled=true"########## Database connection ##########  [OK]   Connection to centreon  [OK]   Connection to centreon_storage  [OK]   Connection to centreon_map########

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. 

Hello,I need to migrate a large amount of data from an old centreon server to a new centreon server.So I can use the migration document, but can I export only a part of the database? Or can I just transfer all the data at once?Because I have a large amount of data to transfer (on average 200GB in centreon_storage).Thank you for your answer.

Hello the Centreon community…I use a Centreon (IT-100) on witch I have A Windows host monitored. Temporarilly we added 32 CPU cores then return to 12 CPU. But all perfdata (for the 32 CPU) are still displayed on the graph with N/A value.Is it possible to purge the no more used perfdata of a service and show only the 12 CPU core  ? Best regards

Hello,I have an installation with a server with all services. I have the server in Azure. We have deployed an Azure MySQL instance to become the Centreon server database.Is there a document that explains how to migrate the local Centreon database to one from Azure? I have not been able to find anything on the subject in the documentation.Thank you

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.

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 

Please provide the steps that need to be followed to migrate from centreon to nagios as we are in the plan of migration.

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.  

Hello,I'm interested in the Centreon ( the open source version)  I understand that the solution provides hardware monitoring.I wanted to know if the Nagios Core solution also offers monitoring for the following elements:Web Applications (internal IS and SaaS IS) (Access time to the service, definition of business actions, transactional errors, response time, incidents on plugins, etc.)Software installed on workstations (examples: Loading time, errors, CPU and memory usage. For the Office suite, a more detailed view (email opening time, waiting time for sending, opening time for encrypted emails, opening time for the calendar, opening time for Teams, display time for Teams, etc.)Operating System (examples: crashes, blue screens, driver issues)Antivirus, EDR (examples: Impact of the process on equipment load)Filers (examples: Network drives, OneDrive)Equipment startup (Example: including details up to the end of session loading as well as user-initiated shutdowns "button")I wanted to kno

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.

Hello,I have a need to check the file system usage at OS level for my infrastructure. For physical servers, I used the snmp templates and i can check the FS usage but for VMs I am not able to find the right service template. is it possible? if yes, could you please tell me the right service template. 

Hello TeamI have just added few ESXi to the centreon. All monitored services are ok except ‘Esx-Memory’, which has status UNKNOWN with error: Cannot get counter 'mem.state.latest' for the sampling period '300' (counter level: 2, sampling level: 1) . I found some advise that it can be fixed in vcenter web client but i cannot find where to change value from 1 to 2 for ‘ mem.state.latest ‘ settings, which is responsible for this counter.

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. 

I'm trying to export Centreon monitoring data to Graphite as per "https://www.centreon.com/export-data-graphite/" document. and I'm getting below error in Centreon Broker Master log.[1707810605] error: endpoint applier: no matching type found for endpoint 'Graphite'please help me to pinpoint this issue.

i have this issue : Reason: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'pluginpack_dep_id' cannot be null For information all the extention are updated to the last version

I am unsure about the rates of traffic I get for my interfaces on my switch. In the picture you can see that the incoming traffic remains under 1 Megabit/s. But I got  an internet speed of much more than 1 Megabit/s.

Bonjour,J'ai un problème avec proc-ntpd. En effet, le service ne fonctionne pas lorsque j'essaie de surveiller mon central. L'erreur est la suivante : "Status information CRITICAL: Number of current processes running: 0".NB : J'utilise Debian.

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?
