Nagstamon 3.8 /3.9 and Centreon 22.04.0

[RAICO-IT]

Hello,

We have a problem in the interaction of Nagstamon 3.8 or 3.9 and the new Centreon version 22.04.0. Nagstamom only shows the message "Empty host XML result" We have already tried everything possible to solve this problem, but we are not getting any further. Jumping from Nagstamon to Monitor, Host etc. works without errors. Does anyone have an idea how we can solve this problem or is the Centreon version too new and everything is different there? We would be very grateful for any tips!

[HenriWahl]

Which version of Nagstamon 3.9 do you use?

[RAICO-IT]

We use the version 3.9-20220619. But even with the officially released v. 3.8 we get the same message.

same problem for me since 22.04..... "Empty host XML result"

[BenoitPoulet]

Hello,

Nagstamon do not support Centreon higher than 21.10, even in the 3.8.

The support for Centreon 22.04 and the API V2 has been added to Nagstamon version 3.9.xxxx.

BUT there is no access to it, as the integration is missing : no config screen, no possibility to switch on the right class

as discussed here : https://github.com/HenriWahl/Nagstamon/issues/812

Here we have the same problem.

centreon 22.04 and nagstamon 3.9 :(

[HenriWahl]

Please check the latest testing release from https://github.com/HenriWahl/Nagstamon/releases/tag/latest which tries to access this issue.

[RAICO-IT]

Hello to all who have worked on this problem. With the new version everything works again. It's nice to see that sometimes things work in IT! Many thanks to everyone who was involved in solving the problem!

[jcdubassin]

Hi everyone ! Doesn't work for me with :( Centreon 22.04.0 and nagstamon 3.9-20220626 Installer : Nagstamon-3.9-20220626-win64_setup.exe

Same version for me , works fine ( centreon 22.04 )

[MrManjah]

Thks @jcdubassin . Do you use a SSL certificate on Centreon web server ?

[BenoitPoulet]

@MrManjah Can you give more information ?  Centreon version ? Error you have and if you can, enable the debug and post the log (without private information)

I run this version on Centreon 22.04 with valid SSL certificate, and on another one in HTTP.

Please note that using «autologin» is not supported on 22.04, you must use login/password. Be careful to try with the latest version posted 3 hours ago https://github.com/HenriWahl/Nagstamon/releases/tag/latest

Hi @BenoitPoulet , Here the informations : Centreon version 22.04.0 and nagstamon 3.9-20220626 with the latest binary (18h ago) No autologin

[BenoitPoulet]

I can see that the auto-detection of the Centreon's version failed.

The auto-detection relies on this page , car you to try to access to it without being logged into Centreon ?

https://server/centreon/api/latest/platform/versions

[MrManjah]

It work in private browsing, without authentication prompt with result like this : {"web":{"version":"22.04.0","major":"22","minor":"04","fix":"0"}.....

[MrManjah]

[BenoitPoulet]

Please be careful, the latest beta release publish the 04/07 from commit #376eee8, does not contain the Centreon 22.04 support anymore. @HenriWahl is this intended ?

[HenriWahl]

No, this is not intended. I am checking what went wrong.

[HenriWahl]

Building 3.9-20220704 at the moment, shall be available in some minutes and contains the merge again.

[ASLLR]

Hello,

I've the same problem : https://$SERVER/include/monitoring/status/Hosts/xml/hostXML.php?num=0&limit=9999&o=hpb&p=20202&criticality=0&statusHost=hpb&sSetOrderInMemory=1 CGI Data: None

I use Centreon 22.04.1 with Nagstamon 3.9-20220807.

Thank you for your help

[HenriWahl]

@ASLLR as this thread grew a lot - which problem exactly?

[ASLLR]

Hi @HenriWahl thank for your answer, i speak about the compatibility with Centreon 22.04. I've update my server and after nagstamon stop working with "Monitor URL Invalid". In debug mode i can the the line : https://$SERVER/include/monitoring/status/Hosts/xml/hostXML.php?num=0&limit=9999&o=hpb&p=20202&criticality=0&statusHost=hpb&sSetOrderInMemory=1 CGI Data: None I think is linked with the forst message of this issue.

Best Regards,

Hi guys,

With Nagstamon-3.9-20220807-win64.zip, I got the following despite I had uncheck the box ignore ssl certificate and/or setting my server's certificate and/or the complete chain:

DEBUG: 2022-08-08 09:51:52.426089 Monitor server FetchURL: https://myfqdn/centreon/api/latest/platform/versions CGI Data: None ERROR: 2022-08-08 09:51:52.552304 Monitor server Traceback (most recent call last): File "urllib3\connectionpool.py", line 703, in urlopen File "urllib3\connectionpool.py", line 386, in _make_request File "urllib3\connectionpool.py", line 1042, in validate_conn File "urllib3\connection.py", line 414, in connect File "urllib3\util\ssl.py", line 449, in ssl_wrap_socket ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "requests\adapters.py", line 489, in send File "urllib3\connectionpool.py", line 787, in urlopen File "urllib3\util\retry.py", line 592, in increment urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='myfqdn', port=443): Max retries exceeded with url: /centreon/api/latest/platform/versions (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)')))

If that can help, I remember that I had to add some "self.session.verify = False" in multiple place (Generic.py & Centreon.py) to implement quickly (& reaaaally dirty) the fix from Benoit but I don't remember exactly the modification I made. The changes also fixed the issue with the verification of updates as we have SSL decryption in our corporate network.

[HenriWahl]

@ASLLR Do you use autologin which should NOT work as described in https://github.com/HenriWahl/Nagstamon/issues/815#issuecomment-1170180568 ?

[HenriWahl]

@brice-automatizit did you check or uncheck the ignore SSL setting?

[ASLLR]

@ASLLR Do you use autologin which should NOT work as described in #815 (comment) ?

Hi @HenriWahl no i'm not using autologin.

Best regards

[brice-automatizit]

@brice-automatizit did you check or uncheck the ignore SSL setting?

Indeed, I *checked the box to ignore the TLS/SSL certificate

[JGomsss]
