No active checks on server: host [zabbix] not found

[zabbixfk]

Hi All,

I am trying to setup zabbix server and agent on same server. But getting error in logs saying "host not found" on logs, and on GUI it says, "Zabbix Server is not running, Information Displayed may not be correct"

 20081:20130604:113906.364 cannot send list of active checks to [192.168.1.123]: host [zabbix] not found
 20071:20130604:113907.318 Zabbix agent item [agent.ping] on host [zabbix] failed: first network error, wait for 15 seconds
 20076:20130604:114007.420 temporarily disabling Zabbix agent checks on host [netmon]: host unavailable
 20118:20130604:113906.364 No active checks on server: host [zabbix] not found

Below are my configs.

LogFile=/var/log/zabbix/zabbix_server.log
PidFile=/var/run/zabbix/zabbix_server.pid
DBHost=localhost
ListenIP=192.168.1.123

/usr/local/etc/zabbix_agentd.conf:98:Server=192.168.1.123
/usr/local/etc/zabbix_agentd.conf:140:ServerActive=192.168.1.123
/usr/local/etc/zabbix_agentd.conf:151:Hostname=zabbix

Also in zabbix.conf.php,

$ZBX_SERVER      = 'localhost';
$ZBX_SERVER_PORT = '10051';
$ZBX_SERVER_NAME = 'zabbix';
?>

Netstat shows ports are opened

tcp        0      0 192.168.1.123:10051      0.0.0.0:*               LISTEN     
tcp        0      0 192.168.1.123:10051      172.17.77.51:58906      TIME_WAIT

And my ping to zabbix, gives correct ip address, i.e 192.168.1.123 ( dns resolves properly, and hostname gives me "zabbix", also in /etc/hostname).

Any pointers are greatly helpful.

Thanks.

Pretty sure Active checks use the hostname that is given in the config and the hostname that you put on Config > Hosts. If they don't match exactly it doesn't work.

Check that your Config > Hosts actually say's "zabbix" and not something like "Zabbix" or "Zabbix Server" etc.
