Journalisation des modifications de configuration - Logging configuration changes

Bonjour, Lorsque j’utilise le menu (centreon 22.10 bientôt migré) administration - Logs je subis une vague d’erreur ‘ooops something went wrong’. Parfois, j’arrive jusqu’à la page mais impossible de faire une recherche pour les mêmes raisons.Alors, est-ce que quelqu’un a une idée sur ces erreurs ? Sinon, savez-vous ou sont ces informations ? (base de donnée ? Fichiers ? Logs ? ) pour faire une consultation manuel.Merci de votre aide,Pierre

Fetching the content of an HTTP call

I want to add monitoring of Ciphermail gateways to my Centreon instance. Reading the documentation, Ciphermail provides HTTP endpoints that returns a {OK|Warning|Critical|Unknown}report. I thought I could use the HTTP Server connector but this seems to force you to test the content of the response in one way or another. Is there a way to just use the content as-is?

Total access point: 0

Hello everyone,I’ve been testing Centreon with the IT-100 license and am trying to manage my Aruba Instant On 1960 switch. However, I’m encountering some issues. Specifically, I’m unable to retrieve any information from the switch.The switch is connected, and the ping works fine. However, when I try to retrieve the CPU usage, my new service called "Aruba1_cpu" uses the “Net-aruba-Instant-Ap-Usage-SNMP” model, but the status shows:"OK: total access points: 0."Could anyone help me understand why this is happening and how I can resolve it?

Performance issue with Centreon's database

Hello,Since upgrading to Centreon 23.10 (since 21.10), I've been experiencing frequent slowdowns in the Web UI.From time to time, I have to restart the Centreon server to restore service.Analysis has shown that a very specific request is the cause. This query crushes the performance of the MySQL server. It seems that the indexes are not being used (FULL SCAN).The query is attached.Can anyone help me identify the cause, usage or process that triggers this query?Here is the SQL request SELECT SQL_CALC_FOUND_ROWS DISTINCT 1 AS REALTIME, resources.resource_id, resources.name, resources.alias, resources.address, resources.id, resources.internal_id, resources.parent_id, resources.parent_name, parent_resource.status AS `parent_status`, parent_resource.alias AS `parent_alias`, parent_resource.status_ordered AS `parent_status_ordered`, parent_resource.ad

Self Monitoring failures on new VM install upgraded to latest version

Hi all, I recently did an install of the free edition of Centreon. All I’ve done was install the VM and update everything to the latest versions and now I’m receiving a few errors in the services section and a bunch if unknowns. The first is for proc-postfix and is CRITICAL: Number of current processes running: 0. I suspect this might just because postfix isn't running and probably isn't a big issue.The other is for Connection-Time and is CRITICAL: Cannot connect: Access denied for user 'centreon-engine'@'localhost' (using password: YES). I also see this in a large number of the unknown issues. Would anyone be kind enough to point me in the right direction on how to fix this? Thanks

Network trafic check with custom oids

Hello, I'm planning to leverage Linux TC queues to be able to implement trafic from/to a specific IP address in Centreon.My primary idea is to be able to graph each iSCSI multipath connection independently.I plan to rely on this project extending SNMPd with custom OID providing metrics per TC queue:https://github.com/mum4k/tc_reader/ It provides two modes, one showing metrics for a single queue and another one aggregating two queues together to emulate input/output. Format is described like this:myOID data will be in this hierarchy:myOID.1 - tcIndexLeaf                   - Stores integers, the SNMP indexes assigned to Qdiscs and Classes.myOID.2 - tcNumIndexLeaf                - Stores an integer, the count of indexes assigned to Qdiscs and Classes.myOID.3 - tcNameLeaf                    - Stores strings, the names of Qdiscs and Classes. Names are in the form "eth0:2:3", which means interface eth0, Qdisc 2, Class 3.myOID.4 - sentBytesLeaf                 - Stores counter32, the sent byt

Question about Linux-SNMP-Uptime service

Hello everyone, i have a small problem that impact only a few of the hosts that i monitor.The most blatant are “Server1” and “Server2” (cf pictures)Server 1 and 2 both have as a check command “Linux-SNMP-Uptime” (defined by their hostgroup) However they do not behave exactly like other in their hostgroup neither are they behaving like each other, and i cannot understand why. As you can see in this image, Server one (sometimes) says that the warning threshold is wrong, and Server2 that the uptime is Critical for being 465 days The problem is that i never inputed any of these weird warning values for server 1 and other servers with as much uptime as Server2 do not show any critical state.Here we can see that Server1 command act as if some weird values are used to check warnings and critical states.Server2 seems to have regular options.So There is what they show half of the time , whether shown as down or in critical status because of something i do not understand, however, sometimes they

AS400 - Check jobs in subsystems

Dear community,We would like to test whether a certain number of jobs with known names are running in a subsystem. Example: EDIGEDA should be running in ROBOT.We would also like to test whether at least 1 job is running in a sub-system. My idea was to test via :  --filter-subsystem-name=‘^SUBSYS$’ --filter-subsystem-library=‘LIB’ --critical-status=0 Is it necessary to test a warning state in this case?Finally, is it possible to manually create all the tests in the CLI, as we will have a large number of them on several systems?Thank you in advance for your answers,Best regards,Jean

var/lib/mysql growing 5GB per week

Hi at all,the volume var/lib/mysql growing 5GB per week. I gave it more space two weeks ago, from 60GB to120GB. This is the graph in 4 months:  Two weeks ago the volume filled up, this caused the db logs table to be deleted. I recreated the table, but now it’s not partitioned. So, I have two question: Why the var/lib/mysql volume growing so quickly?  Is it a problem if the logs table is not partitioned? I'm waiting for a response, thank you very much!!
