Hi ​@Bernard.Lheureux ,

did you use regex filter in the widget hostgroup-monitoring ? 

Just to add my 2 cents to this question : 
We have the same behavior after the upgrade (24.4.2 to 24.10.2)

In the widget, we use “Hostgroup Name Search” with either “=” or “LIKE”, none of them work
If I create a new widget with this “hostgroup-monitoring”, I can see a strange behavior : 

By default, I can see all of my groups without any filters, but the moment I try to filter by hostgroup name, even if it’s a group name I just copied from the previous view, the widget stays blank.

​@Bernard.Lheureux seems to say that this behavior wasn’t present in 24.10.1, i’ll maybe try to downgrade to this version, in the wait of the next release

EDIT : Just to be clear, the monitoring itself still works, when we go to the monitoring pages we have every details needed, but we have to search them manually, instead of the easy view we had previously with custom-views

I put a new comment and not an edit because I just found a workaround : 

I was looking for differences between an old version and the actual version of the hostgroup-monitoring widget, and found out that it changed between the releases.

I didn’t really understand the changes, but when i change the file for the previous one, and restarted my services, it worked, so I’ll keep it this way

Path of the file to replace :

And the last step, I restarted my services (not sure if needed)

systemctl restart cbd centengine gorgoned

With this, everything is back to normal

If someone in the dev team can patch this before the next release it would be great, thank’s for your work !

Hi ​@baskmobile,

thanks for the solution. i didnt’t try it because it’s not validate by Centreon Team… But i think they need to update there code of the widget quickly !

Hop there read this post.

Hi ​@SavCent 
Understandable, if you don’t trust this code block, you can still find it if you do a fresh install of an older version of centreon (24.4 for instance)
You can also compare the code I posted to the actual content of your index.php file, if you have enough time to point out to the problem

Hopefully it will be solved in the next minor upgrade, i don’t know if this bug is on their roadmap, i don’t find it in https://github.com/centreon/centreon/issues or https://github.com/centreon/centreon/pulls , but maybe i don’t use the right tags to find it

Good luck with your dashboards =) 

Hi ​@baskmobile ​@Bernard.Lheureux ,

i made an IDEA for this problem. Could you please vote for it ?

It’s done, even if I think it’s not what should be done.

A rework of the new code should be better than what I did (I just put back the old version)
