Our setup is in WSMAN domain config. Thank you in advance for your inputs/suggessions.  

Hello,I'd like to execute, with Dynatrace API v2, a GET request (synthetic - HTTP monitor execution).- Is it possible to perform this with the Dynatrace Centreon plugin ?- If not, is there an other way to proceed ?Thanks,

HelloI have a behaviour that I can't identify.For memory/swap probes I have 2 equivalent services (they have the same service model), but one has graphs that work, while the other does not. What I don't understand is that on the CPU and Load probes, the graphs work correctly.The graph model is related to the service model, so they have the same configuration.Do you have any ideas?

Hi there !I’m about to install Centreon on a Debian virtual machine, and stumbled upon something in the documentation that left me wondering.The prerequisites chapter of the documentation states that the server must use LVM. Ok, no problem here.But it also indicates how my server should be partitioned, without saying what would happen if I don’t follow these indications.So, I’d like to know : what am I risking by using LVM with a different set of logical volumes ? For example… fewer logical volumes (that would suit me 🤔)Thanks.

Hi Team,I had successfully installed centreon NSClient on windows server 2019 and modified the parameter in nsclient.in file and add my poller servers IP address like 172.24.XX.XX/32. restarted the nscp service. what is the next step ? unable to view the systems in Centreon Server’s host for monitoring.Please help.  Thanks.

Hi,I’d like to share the feeling I have about the new “Resource Status” page with the community.In my opinion, the old pages should have never been considered deprecated and not used by default. This is rather this new page that should have been considered a feature preview and made optional.These are some of the reasons I see:1) The new page needs a screen with a big definition or else the detailed status (ie: the output of the plugin) is not even visible without removing some columns or zooming out. To put it another way: the layout is far less compact.2) It’s impossible to filter on the plugin output (ie: the “Information” column in the new page). This is handy when you have a specific issue on some checks, and in some other cases.3) The popup on mouseover just doesn’t exist. This is handy to quickly see host or service information, without the need to load a new page.I’ve been told that the deprecated pages were still maintained for bugfix while there is still missing features in t

Hi everyone,I already post this question but I think it was in the wrong section so I repost it here. I wondered if it’s possible to embed charts related to alerts in side email notification ?

Hello,I have a central server and a remote server. On the central server I can see the pollers are running but the hosts from the remote server all show ‘unreachable’. On the remote server I can see that the hosts are all ‘up’ and reporting correctly.On the remote server under platform status > broker statistics on the remote server I can seeforward-to-master is stuck on ‘connecting’On the central server I can see it is ‘listening’ On the central server I can see both pollers are running: What should I be checking to diagnose the l​ack of communication between the two?I do not see any errors on the remote servers gorgoned.logon the central servers gorgoned.log I see the following:ERROR - [autodiscovery] -class- host discovery - cannot get platform versions - cannot decode json response: malformed JSON string, neither tag, array, object, number, string or atom, at character offset 0 (before "<!DOCTYPE HTML PUBLI...") at /usr/share/perl5/vendor_perl/gorgone/class/tpapi/centreonv2.p

Hello everyone,I am currently installing Centreon for my company.So I have a little question :)Would it be possible to activate pam_ldap on AlmaLinux 8 in order to connect with AD on Centreon?

On my test Centreon v23 I was notified that some Connectors needed updating so I proceeded.Some errors popped up for the Generic SNMP connector but after waiting and pressing OK everything looked to be fine. On closer inspection I noticed several extra ones that we did not have before, nor do we require have now also been installed:I cannot remove them either - it seems to go through the motion and the green installed icon disappears, but after a refresh they all come back. No messages are displayed and none of them are used by any hosts, using the re-install button has no effect. Rebooting the RHEL8 server does not help.How can I get rid of them?

Dear Thewatch community, Following an advice given by the technical guy from centreon support. I will try to explain my issue.I tried to monitor the SAN Netapp Solidfire without any success.First of all using SNMP queries, i must say that everything is ok when i use snmpwalk.Then using the RESTAPI which seems a bit different than in the plugin. So, my question is it planned a day to make the plugin compatible with this SAN ? Or should I forgive it and prepare to make my check by getting the OID for each control. Many thanks for your advices. BR,

hellowe recently deployed some hyper-v nodethey are running windows 2022 with centreon-nsclient 5.2.41 and they have more than 64 thread the cpu check return abnormal value :  this is probably a bug from the NSClient program, but has anyone encountered this problem and managed to fix it? Thanks in advance
