    Trying other mirror.

      When you have the message “poller not running”, this means the ndomod2 on poller can not communicate with ndo2db. Or ndo2db can not communicate with mysql. Check you configuration on ndo2db.cfg and ndomod.cfg

    Hi, thx for the reply.

    Config file seems to be good for ndo2db.cfg and ndomod.cfg.

    There no problem after the upgrade, i can reboot all pollers, they still online and the synchronisation is okay and uptodate.

    The poller appear offine after I use the option “Move Export Files” in Centreon> Config > Nagios Configuration Files Export.

    Please help.
