Hello,

I need some help after the crash of my centreon monitoring that stop working after a disk full on the central poller.

After this crash, I found that the poller server was working with the date set to 2043 instead of 2022.
I have correct the date and sync the 2 servers with a ntp server.

But now, during the restart of the poller (systemctl restart centreon.service), I have this error in the log (/var/log/centreon-broker/central-broker-master.log) : 

[1646820491] error:   failover: 'connection-to-CENTREON.POLLER' cannot connect endpoint.

Centreon Broker 20.04.17 log file closed

Centreon Broker 20.04.17 log file opened

[1646820551] error:   conflict_manager: error in the main loop: could not prepare update query for event 'host_check' on table 'hosts': could not update poller:  Out of range value for column 'last_alive' at row 1

[1646820552] error:   failover: 'connection-to-CENTREON.POLLER' cannot connect endpoint.

[1646820555] error:   failover: 'connection-to-CENTREON.POLLER' cannot connect endpoint.

Also, the centreon service is active but exited :

systemctl status centreon

How could I correct it ?

Thanks for your help

Hello @GSA69006 

The errors seems to be on the database and an incorrect size of the column last_alive.

Could you send us the result of this command:

mysql -u centreon -p centreon_storage -e "DESC instances"

You can find the password of centreon database user in /etc/centreon/centreon.conf.php

The values in the last_alive column are correct :

Central = 1646726855  (Tuesday 8 March 2022 08:07:35 GMT)
Poller = 1646663218 (Monday 7 March 2022 14:26:58 GMT)

No trace of a date in 2043 that could explain the problem :frowning2:

I’m kind blind or tired ><
Wrong table my bad.

Could you give the return of this command:

 mysql -u centreon -p centreon_storage -e "desc hosts"

And could you tell me if you have any kind .queue. file in /var/lib/centreon-broker?

But there is no last_alive column in this table.

That what I was thinking when I checked on my platform.

*mumble*

 

Could stop cbd using `systemctl stop cbd` command, and then remove all the file in /var/lib/centreon-broker (with rm -rf /var/lib/centreon-broker/*) ?

 

And start it again ?

Done, but centreon service still exited after restart

The central-broker-master.log have changed :

Centreon Broker 20.04.17 log file closed

Centreon Broker 20.04.17 log file opened

[1646919200] error:   conflict_manager: error in the main loop: could not store host status:  Out of range value for column 'last_time_up' at row 1

Here’s the max values in the last_time_up & last_time_down column :

MAX(last_time_down) = 1646920764 (Thursday 10 March 2022 13:59:24 GMT)

MAX(last_time_up) = 1646920761 (Thursday 10 March 2022 13:59:21 GMT)

It’s going to be little overkill but could you in that order:

  • stop cbd on the central,
  • stop centengine on the central and on the poller,
  • remove all the files under /var/lib/centreon-broker/ (all your servers),
  • delete all the retention.dat and status.dat in /var/log/centreon-engine/
  • remove all the .queue. files under /var/lib/centreon-engine/
  • And restart cbd and centengine
