Version: ⭐ 25.10

Switching versions of BBDO

From Centreon 25.10, BBDO v2 is deprecated. When you upgrade your Centreon version, the central server automatically switches to BBDO v3 (remote servers and pollers will use BBDO v3 automatically once you deploy the configuration). However, here is a procedure for switching versions manually if necessary.

BBDO must have the same version for all servers in your architecture (central server, remote servers, pollers). You must also use BBDO v3 with your stream connectors.

Procedure

On the central server, go to Configuration > Pollers > Broker configuration.
Select the server you want, and on the General tab, in Advanced options, select the version of BBDO you want from the BBDO version list. Then click Save.
Do the same with all the elements listed on the **Configuration > Pollers > Broker configuration page
Restart gorgoned on each server:
```
systemctl restart gorgoned
```
Deploy the configuration for all servers.
Stop the following services:
- On the central server and on remote servers:
```
systemctl stop cbd centengine
```
- On the pollers:
```
systemctl stop centengine
```
Start the following services:
- On the central server and on remote servers:
```
systemctl start cbd centengine
```
- On the pollers:
```
systemctl start centengine
```

You can check in the logs which version of BBDO is active for a server:

central broker:

tail /var/log/centreon-broker/central-{broker,rrd,module}-master.log

remote broker:

tail /var/log/centreon-broker/<remote_name>-{broker,rrd,module}-master.log

poller module:

grep "using version" /var/log/centreon-engine/config0/centengine.log

The following line states which version is used for each server:

[2025-10-17T14:53:44.828+00:00] [bbdo] [info] BBDO: peer is using protocol version 3.0.0, we're using version 3.0.0
