Can't modify brokers with RRD field

Hi guys,

 

I search about this topic but I didn’t found anything so If there is another thread about this my apologizes.

 

I have an error in my Centreon Central installation. The version is 24.10.12. I updated trying to resolve the issue but it persists.

 

The error appears when I tried to create a new input or output on a broker configuration and it has a RRD field.

 

I have tried with Unified SQL and RRD file generator and both of them fails. The first due to ‘length’ parameter is missing and the second due to RRD file directory for metrics.

 

 

If I modify the central-broker.json and add the output manually there is no problem at least until I export the configuration.

I tried to do an insert into in database (keep calm I did an snapshot, I know this is not an option) but It doesnt work properly because It appears without name like this.
 

So anyone has any idea how to resolve? I installed a new Centreon in a new machine and It works properly. 

 

I would like to say this Centreon comes from v18 or v19. I upgrade to v22 and after that v23 and v24. I didnt see anything related to the error on logs.

I could provide any information that you need to resolve.

In case of empty set, you can populate the table with this commande (i took it from my lab Centreon 24.10)

use centreon_storage;
INSERT INTO `config` VALUES
(1,'/var/lib/centreon/metrics/','/var/lib/centreon/status/','/var/lib/centreon/nagios-perf/',180,365,'0',10,20,NULL,NULL,'0',31,365,'/var/log/centreon-engine/centengine.log.log',0,'1',0,0,0);

And your Options page should work

Hello ​@Egoitz ,

Are the fields which cause error empty?

length field match this one
metric_path match this one

 

From the Centreon UI, can you go to Administration > Parameters > Options page and check if the fields are not empty?

Especially :

  • Path to RRDTool Database For Metrics
  • Retention duration for performance data in RRDTool databases

For what i understand, this fields can only be set on this page, and their values are then automatically fetch in the broker config

 

If you have this errors, it means the config cannot get any value, so maybe in the update process, some fields lost their values

 

Hope it helps

​@vcoum Hi!

Thank you for the reply.

 

I followed your instructions and I think I found root error. I went to Administration > Parameters > Options and it is a blank page.

 

 

So I think the problem is not in the bdd. I am going to compare the last Centreon update (/usr/share/centreon) with my Centreon.


If you think the problem is other please tell me.

Try to open the browser console, in the network tab, and retry to go on the Administration > Parameters > Options page

Check if you find some errors

Also, check the Apache2 and PHP logs

 

The pages used for this form are located in the /usr/share/centreon/www/include/Administration/parameters/centstorage/ folder (maybe there is other files somewhere else)

​@vcoum I didnt see anything on the apache log.

On the Php log I found that:

Okay it seems there is a problem in the PHP process

Connect to your centreon database and use this query

SELECT * FROM centreon_storage.config LIMIT 1;

You should have a result who look like this

 

If you have an empty set, this is the cause of your problem

​@vcoum I spent a lot of time trying to resolve this problem and you did it in less than an hour. Great!! 

 

Thank you guy! Now I can create an Unified SQL and RRD File Generator.

I have a last question. Should there are more lines at config table? I mean it could be possible I have more errors like that and I dont know why. I can compare new centreon database against production database but I would like to know your opinion.

I promise I won’t disturb you more times.

​@Egoitz I’m glad it worked ! 😁

For your question, it seems there is always one lines in the config table (i checked on other Centreon platform), so your table config is at normal state now
