Hello,when upgrading from centreon 21.04 to 22.04 on a central and a poller everything went well except when restarting the services I got the following error:

vim /var/log/centreon-broker/central-broker-master.log

on the poller I have the following error

vim /var/log/centreon-broker/poller-module.lo

>*****] tcp] error] Error while reading on socket: End of file
>******] core] error] failover: global error: Attempt to read data from peer central:5669 on a closing socket

Thanks for your help

Check your Broker-Configurations  (Configuration/Pollers/Broker-Configuration) and make sure the BBDO-Version is the same everywhere.

Check your Broker-Configrations on the Systems themself (/etc/centreon-broker/ on mine) for any old ones lying around breaking it.

 

Afterwards restart all instaces by “systemctl restart centreon”

Hello Timo,

last night I actually put everything in version V.2.0.0 on the whole and it works after

“systemctl restart centreon”

do I have to stay on this BBDO version (V2) or do I have to switch to V.3.0.0?

and what is the point of this new version?

thank you in advance

Idinar

Hello Idinar,

 

i hope someone from the Team will answer you on that, as i actually can’t answer that question. My Plattform is also on V2.0.0 at the moment, so i will also be interested in the answer you receive.

 

I had the same Problem before and this was what helped me, so i thought it might help you also.

 

Regards

Timo

thank you very much for your quick feedback

we will wait for someone who already uses BBDO v3

 

Regards

@Laurent Hello,

An idea on using BBDO V.3.0.0 on centreon 22.04?

This new version brings several performance enhancements (mostly about the size / payload of events). 

Switching to v3 require to carefully stop pollers and central broker, clean hypothetical memory and cache file, and then restart to have every pieces using the same protocol version. 

 

It’s not mandatory to switch to v3 and you can totally choose to wait a moment as it’s still young. Anyway, if you move with it, let us know if any problem is showing up.

 

Best
