Netapp Restapi FRU error

Hello,We monitor netapp stockage with the Netapp Ontap Restapi.We have an error on Hardware when all fru are not populated.Here a part of the command return with the debug flag:"frus": [        {          "type": "module",          "id": 0,          "state": "ok",          "part_number": "XXXXXXXXXXX",          "serial_number": "XXXXXXXXX",          "firmware_version": "XXXX",          "installed": true        },        {          "type": "module",          "id": 1,          "state": "error",          "installed": false        },        { I don’t seem to be able to filter out the fru module without disabling completly the fru check with the --filter=”fru”. To disable the check on one instance, the plugin seem to check with the instance id eg: the serial_number for the fru. But with no fru installed, there’s no serial number… Conclusion: to continue to monitor correctly this netapp, I have modded the script “centreon_netapp_ontap_restapi.pl” and added the line “next if not ($fru->{in

CORS policy

My company has a Centreon service (network equipment monitoring for the entire company) hosted locally. The monitoring information is visible on a WEB page.I would like to retrieve some information (state of certain network equipment/WEB pages) to display it to all staff.This is where an API comes in, initially I made a "curl" request to retrieve an identification token in order to contact the API.In a second step, I made a request with the token to retrieve all the monitoring information in JSON format.So far, everything is working.Now I would like to "automate" this process by making it accessible on a WEB page.I am using javascript code (see below) to query my API but it is not working. The code seems good but it is blocking on the server side.  I was given a suggestion to add a line in the file "/opt/rh/httpd24/root/etc/httpd/conf.d/10-centreon.conf", but it made no difference :    Header  set X-Frame-Options: "ALLOW-FROM http://your.url.com/"I also looked into the meaning of CORS,

Create External BBDD with SQL

I am trying to implement HA, and I want the central server and central server 2 to store their data in an external, shared database.I have tried to make the connection to a SQL server and I get there but I get "MYSQL server has gone away",. I think this is because I am using a SQL server and not MYSQL, is this what is stopping it from working? Has anyone done or knows if it is possible to do what I am asking?Thank you very muchTranslated with www.DeepL.com/Translator (free version)

How to handle stale process

What is the best practice to handle stale process from services?Most of my services have a 5 minutes polling, although some of them have their last check reaching hours.When I list process from centreon-engine they seem to be stuck even with max_execution_time set to 60sThese scripts are basically consulting large MIB tables which runs in 5 seconds average but for some reason they stack in the process pipeline. I’d like to schedule a script to cleanup those stuck process. Since I don’t want to mess with the system crontab, using a centreon service could be the best way to schedule it. How can I set the right permission to centreon-engine be killing these process though this script?

Service templates inheritance BIG issue

Hi, I am migrating my monitoring configuration from NagiosCore and NagiosQL to Centreon, but I have a problem with the service templates with which I am quite desperate.Unlike with host templates (which you can add more than one template per host) in services, Centreon only lets you add one template.I have already seen that in Centreon this works using inheritance, but is there any other way to make it work by groups?As I said, I currently add to each service several templates which have an order that matters.I have a problem since for each line you see in the image below (these are all the possible combinations in my monitoring), I would have to create a lot of different "routes" duplicating templates.Let's see if I explain better with an example...If I want my template A to follow the following inheritance, A->B->C->D but then I want another service to follow the following inheritance A->E->C->D, with the Centreon inheritance system, I understand that I should creat
