Infra Monitoring Platform

I'm currently looking for a reliable SMTP service provider for my business (mainly for transactional and promotional emails). A lot of my friends have suggested SMTPmart, saying it's great — but honestly, I haven't used it before and don't know much about their features, deliverability, or support.Before I make any decisions, I’d really appreciate some genuine feedback from people who have actually used it.

I have detected zombie services in the database associated with my Central server (version 22.10), while the corresponding entries appear to be consistent in the database of my Remote server. Could you please advise on the recommended procedure to clean up these orphaned/zombie services and properly identify them? Central DB :+---------+------------+------------------------------+-------------------------------------+-------+-----------------+| host_id | service_id | name                         | display_name                        | notes | notes           |+---------+------------+------------------------------+-------------------------------------+-------+-----------------+|     446 |       3686 | hostname.sup.fr | [ORACLE]-JDEDEV-INDEX_INVALID       |       |                 ||     446 |       3687 | hostname.sup.fr | [ORACLE]-JDEDEV-TABLESPACES_NUMBERS |       |                 ||     446 |       36

Hi, I'm trying to configure VEEAM job supervision with NSClient++ / NRPE3, I can't get out of it because I keep getting the “execute command failed” error.I've already tried logging my command directly from my Poller, on my customer's site where the VEEAM B&R is installed. Here's the command I typed and the feedback showing that the command was executed correctly:root@dlg-spoller:/usr/lib64/nagios/plugins# ./check_centreon_nrpe3 -H 192.168.1.37 -p 5666 -t 55 -u -2 -P 8192 -c check_centreon_plugins -a ‘apps::backup::veeam::local::plugin’ 'job-status' ' --filter-name=“” --filter-start-time="" --filter-end-time="86400" --filter-counters="" --ok-status="" --warning-status="" --critical-status="%{is_running} == 0 and not %{status} =~ /Success/i" --warning-long="" --critical-long="" --verbose'OK: Total jobs: 5 - All jobs are ok | 'jobs.detected.count'=5;;;0;Job 'Backup_

Hello, It seems that, at least for us, the functionality that allows the browser to determine the user language is broken. Now Centreon defaults to French for everybody even if the browser language is set to English. Are we the only ones suffering from this issue? Tongit

Bonjour,J’ai ajouté un second poller (dans le même LAN) en suivant la procédure sur le site.Mais lorsque je souhaite redémarrer l’ordonnanceur, il m’est impossible. Un message d’erreur s’affiche :Avez-vous une solution à m’apporter ? Je ne sais pas quelle fichier modifier…Merci pour votre aide !

Github issue: https://github.com/centreon/centreon/issues/8042 Since 24.10.8 (could also have been introduced in earlier versions) all inherited command macros are directly written on the host with an empty value when a new host is added (only on add, does not happen on update host).This also happens on new Host Templates.Problematic situations that can happen due to this bug:Imagine creating a new host based on template T1, somewhere in the template tree is a command which declares macro $_HOSTOPTIONS$. At the moment the template T1 has no value for the macro defined. The new host gets created and the macro is wrongly written on the host with an empty value. Now I set a macro value for $_HOSTOPTIONS$ on the template T1. The recently created h

Hi,What is this warning and could it have a relation with the impossibility to display the Dynamic services configuration page:17:50:37,963 [ Federation Runtime ]: Version 15.0.1 from centreon of shared singleton module react-i18next does not satisfy the requirement of centreon_it_edition_extensions which needs 14.x)  

Hi,Why are (some ?) messages now premoderated?Regards.

I’m facing regular issues with using the CLAPI centreon command.Especially in terms of permissions. I face issues regarding permissions on log files or php files, sometimes it’s files created that are blocking gorgone. I was wondering if there was a clear recommendation in terms of what is required in terms of permissions for the execution of a CLAPI centreon command.Is itas root as apache (i’m running in RHEL 9) as centreon (or other centreon linked user like centreon-engine) as a custom user but with centreon as a secondary group  Would someone that faced similar issues please guide me ?Thank you so much

Dear Centreon Community,While trying to implement a basic “host autodiscver” using nmap, the following error appears after the discovery ends : command not allowed (whitelist) at array index '0'Could somebody please help to correct this basic issue ?Regards,Jean

Hello,I’m in the process to upgrade/mirgrate from 21.04 to 24.10.Everything is “almost” working, I’m actually working on the mail notification.So I follow the doc here : https://docs.centreon.com/docs/administration/postfix/Everything is working as expected, I can sent mail using the test commandecho "Test" | mail -s "Test" user@isp.comBut on Centreon, I do not receive any notification.The Centreon server didn’t even try to sent something (no logs on my SMTP server).So something seems misconfigured on the server, I have doubt on the postfix service itself, as the status is active (exited) but on the doc it is active (running).

Hello,We’ve encountered a recurring issue when querying service macros via the Rest API (v1) (getmacro action). Some macro names are returned truncated or corrupted, it’s random.I can recreate macro, and it’s working but not for longtime.For example, instead of returning:{ "macro name": "TICKET_ID", "macro value": "12345678" } We sometimes receive:   {      "macro name": "ITICAL",      "macro value": "350",      "is_password": "",      "description": "OPTIONNEL - Seuil mémoire en MB",      "source": "App-SS-Process-Memory\nTI"    },    {      "macro name": "KET_ID",      "macro value": "",      "is_password": "",      "description": "",      "source": "generic-active-service-custom\nSE"    }, I have many MACRO on sercice, and i have this problem on differents servicses.  The call is :

Hello,I would like to count how many records encounter a condition into a table, and I would like to rise an alert (warning and critical thresholds) when some values are overset.But I dont want to get only the number as output,but I also want to back a text which is a concatenation of lot of some others fields of this table.So, I think to proceed with "centreon_mssql.pl --plugin database::mssql::plugin" and "--mode='sql-string' " instead of "--mode='sql'" because I need a text output.. But how to do that exactly ?Is someone can help me ?RegardsPS : I'm french speaking.. So Maybe my english here over was not good enough to explain my request as well ? ; )

Hello,I have been experiencing several problems since today with version 24.10 Centreon On-Prem.My pollers can no longer communicate with my central server on port 5669.I have tried the various Centreon procedures to resolve this (restarting the centengine and gorgoned services, looking at the logs, etc.).I'm quite used to these problems in general but this time, strange behaviour is occurring.It seems that the input and output configuration of my central-module-master and central-broker-master have disappeared from the files when I display them via the CLI in SSH.I tried to see what was happening via the GUI but when I recreated and saved them, an error appeared: Could not resolve host: centreon.mysite.com for ‘https://centreon.mysite.com/centreon/api/latest/configuration/broker/1/outputs’.(Obviously, I've replaced the url in the error to show you)Same thing when I modify the input : Could not resolve host: cent

Hello ! I migrated my centreon from a 19 version to a 24 oneFrom my 19 version, I had a poller, that I didn’t touch at all, and now, I would like to get the configuration that is on that poller and migrate it inside the new 24 one (not add a poller to it, but merge it to the new centreon)Do you know how can I do that ? 

Hello, Ive set up centreon server and two pollers, for one poller everything works fine, for the other one, the poller.json file doesnt get sent at all? ive checked in centreon central and i saw it does get generated after export but its never sent to my poller because i cant find it in the poller, therefore i cant make connection between the two, and also in the centengine.cfg file i see broker module on my poller it set to ‘centrlal-module.json” when it should be set to something else etc, im confused why the .json file isnt being sent, if i add it manually will it work? ive even checjed the mysql db on centreon central and i see it has two pollers, so I have no clue whats cuasing it, the ports needed were allowed via the firewall so i doubt they’re the issue,please help i can’t figure it out

Bonjour,Dans un répertoire donné, il y a 1 fichier de sauvegarde par jour.Le plugin NRPE permet de vérifier s’il y a UN fichier présent dans le répertoire qui a une date de modification de moins de UN jour.Exemple : /usr/lib/nagios/plugins/check_centreon_nrpe -H IP -p 5666 -t 60 -u -m 8192 -c check_files -a "paths=E:/Dump/" "pattern=*.bak" "warning=count>1" "critical=count<1" top-syntax='${status}: ${problem_count}/${count} files (${problem_list})' detail-syntax='' filter="written > -1d" "empty-state=CRITICAL"Je n’arrive pas à reproduire le même fonctionnement avec les plugins FTP/SNMP/CIFS. Ils semblent ne pas avoir de fonction pour vérifier la date d’écriture ET le nombre de fichiers attendu.Exemple : /usr/lib/centreon/plugins/centreon_protocol_ftp.pl --plugin=apps::protocols::ftp::plugin --mode=date --hostname=IP --username='login' --password='password' --warning='84600' --critical='' --directory=

Hello,i’ve an issue withe connectivity between centreon central and a remote poller with the 24.10.5 version. My central can reach the remote poller with tcp port 5556 From cental, a netstat command  we can see Fin wait, it’ seems that the client initiale a connection to the remote server but don’t have received the reponse that the connection is established.  From the remote server: we can see  a lot of established connection to the central… Normally i have other remote server, and normally there is only one connection, but not a lot as the screenshot.

Hello,I just upgraded from 21.04 to 24.10.When upgrading the widget, I ahve the following error on the “grid-map” widget.I think is an old that have never been solved :(Thank you.​​​​​​ 

Being the first of the month is was time for me to run my regular updates for my Centreon VMs.  This is  running AlmaLinux 8.10 Kernel 4.18.0-553.60.1.e18_10.x86_64 and Centreon Version 24.04.15 after the new update and it has broken all of my monitoring.  Execute command failed is the error that I am seeing in the status page.  I have rebooted the machine with no change.  Some googling came up with making sure SELinux was disabled.  Initially it was not, but I did change that, rebooted the system again and still getting the same error.Fortunately this is a VM and I did take a snapshot prior to updating so was able to restore functionality quickly.  Did some more research, ran the update again, but still the same result.  Anyone else run into the same issue?  Or would have any further thoughts on what I should check?
