How to clone pollers?

Hi guys! do you have any specific instruction on how to configure a cloned poller? This would be very handy for indrastructure taht is distributed in multiple sites. It is also much more convenient to clone a VM than install everything from scratch. What I’ve learned so far:The usual suspects: IP, hostname , host SSH keys copy gorone config (from guil) and past it on the poller if it’s a new poller: configure engine for it on central if you replace an old poller: Gorgone history, mentioned in here This is probably sufficient for checks to run, but for exapmle platform status->poller statistics stays empty for cloned satellites. Anything else we need to know? Thanks in advance!

Help on centreon availability report

Hi,I’m using centreon since a lot of time on different projects for monitoring purposes. Now the customer asked me availability reports (the option is present) but i have for services, hosts and hosts group, 100% unknown.Looging at the logs on the eventReportBuilder.log i find error on scheduled launched command → 2024-08-08 03:00:03 - ERROR - MySQL error : cannot connect to database : Access denied for user 'centreon'@'localhost' Everything is working fine, RRD performance data are being stored and so on  but all the steps to create the availability view apparently fails.I also double checked the possibility to login as centreon user on the db and it works fine, any idea on what should I check? All my installations (made from scratch following the instructions)have this error. Kind regards

HTTP Collection : content-type "x-www-form-urlencoded"

Bonjour la communauté,Nous souhaitons utiliser le modèle de service HTTP Collection pour interroger une API.Dans le tuto proposé (https://thewatch.centreon.com/product-how-to-21/http-collections-tutorial-how-to-monitor-an-api-2634), le format du payload utilisé pour la requête POST est json :"payload": { "type": "json", "value": { "security": { "credentials": { "login": "%(constants.username)", "password": "%(constants.password)" }}}}L'API que nous souhaitons interroger requiert un content-type "x-www-form-urlencoded".Exemple de requête généré avec Postmancurl --location 'https://xxx/services/auth/login' \--header 'Content-Type: application/x-www-form-urlencoded' \--data-urlencode 'username=***' \--data-urlencode 'password=***'Nous ne parvenons pas à paramétrer correctement le fichier json de la collection pour prendre en compte ce format d'appel.Quelqu’un aurait il déjà rencontré (et solutionné 😎 ) ce cas ?Merci à vous !

HTTP Data collection: Path depth

Hi!I’m trying to follow the tutorialto implement monitoring of SAP SCC. Two issues:HTTP basic authentication: it’s not clear from the tutorial how to get a plain simple HTTP basic auth. Took me hour to figure out (use the source, Luke!) that you just need to pass ‘basic’ like this: "authorization": {"basic": 1,"username": "%(constants.username)","password": "%(constants.password)"}, I would add it to the original post, but the comments are locked. Please add it, so people save a lot of time. Path depth. SAP will respond with a JSON of this type: { "subaccounts": [ { "description": "SAP BAS", "displayName": "SAP BAS", "tunnel": { "state": "Connected", "connectedSinceTimeStamp": 1720773876375, "connections": 0, "applicationConnections": [], "serviceChannels": [], "subaccountCertificate": { "notAfterTimeStamp": 1749540416000, "notBeforeTimeStamp": 1718000816000, "subjectDN": "CN=B0CADA20E31311EBBF8AD

Can't install VMWARE-daemon because PERL(ZMQ::Constants) is necessary

Hello, I currently facing a problem when I want to install “centreon-plugin-Virtualization-VMWare-daemon” to monitor my ESX. It seems that perl(ZMQ::Constants) is required/necessary to do the installation. I already tried to install perl(ZMQ::Constants) with cpan “cpan ZMQ::Constants” : It looks like ZMQ::Constants is up to date … I checked on internet and it seems like no one got the problem, so I’m really lost at this point. I have installed Centreon on a Oracle 9. I installed packages perl-ZMQ-libZMQ4, perl-VMware-VSphere  Is someone already faced this problem ?  Hope I’ll get answer.  KR,

Centreon Plugins - Discover Collection modesTutorial

The Centreon Plugins team recently introduced a new fashion of scraping monitoring indicators. It’s called Collection.  These modes could be seen as 'dumb' boiler-plates, allowing you to monitor 'things' over various protocols or APIs while abstracting some of their complexity. Collection modes rely on a JSON configuration file describing the data you want to get and the processing or mapping you may wish to apply. This kind of mode is handy if you are in one of the following situations:You can't find an existing plugin to monitor what you want or fulfill your particular need. You need to gather data from a in-house, black box, or third-party application and transform it to be easier to analyze. Writing (or asking for) a dedicated plugin appears overkill because you simply want to monitor values and apply thresholds over them. Currently, Collection modes are available for: SNMP (check the tutorial) SQL (check the tutorial)In other words, you can use these on any device supporting SNMP

HOW TO FILTER

Hi there, I have the next problem:We have the alerts from centreon sent via telegram. The point is that we don’t want that many alerts, we only want those ones we are interested in. So I tried to filter that information, only achieving to filter the performance data (which is not the message telegram sends, telegram send the status information).To sum up, I want to filter the info from STATUS INFORMATION and I don’t know how. I have tried with How to play with Regex - Part II | Community (centreon.com) and part 1 and it has been impossible for me to succeed. I`ve been working with centreon for just a couple days now so I will gladly thank any help. This is what I want to filter

how to monitor the presence/accessibility of three different URLs

Hello,I am new to CENTREON.Could someone help me or explain how to monitor the presence/accessibility of three different URLs of our production environments (e.g., akpdev.mydomain.com, akpdev-test.mydomain.com, akpdev-param.mydomain.com) in a single model/service/host, etc.?I would also like to create the command for this and call it in a model or service in order to easily create alerts for these three environments for each of our clients, of which there are  about 250.I imagine I will need to create macros, command lines, templates, services, and then hosts. However, I'm not really sure how to create them, where to start, and how to make all of these features work together to achieve the desired results. PS: H’ve already ilstalled the plugin pack  “centreon-plugin-Applications-Protocol-Http”Thank you in advance for your answer.Sincerely,
