nagios+cacti+npc(pass)

启动ndo2db

[root@localhost soft]# ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg

[root@localhost soft]# service nagios restart

[root@localhost soft]# cat /var/log/messages

Jul  5 17:30:27 localhost nagios: ndomod: Could not open data sink!  I'll keep trying, but some output may get lost...

Jul  5 17:30:27 localhost nagios: Event broker module '/usr/bin/ndomod-3x.o' initialized successfully.

Jul  5 17:30:27 localhost nagios: Finished daemonizing... (New PID=12009)

第一行报错：是因为没给ndo2db文件权限

[root@localhost soft]#chown nagios.nagios /usr/local/nagios/etc/ndo*

[root@localhost soft]# service nagios restart

[root@localhost soft]# cat /var/log/messages

Jul  5 17:37:46 localhost ndo2db-3x: mysql_error: 'Unknown column 'long_output' in 'field list''

这次是，数据库有问题

[root@localhost soft]# mysql -ucactiuser -ppwd123

mysql> use cacti;

alter table npc_eventhandlers add long_output TEXT NOT NULL default '' after output;

alter table npc_hostchecks add long_output TEXT NOT NULL default '' after output;

alter table npc_hoststatus add long_output TEXT NOT NULL default '' after output;

alter table npc_notifications add long_output TEXT NOT NULL default '' after output;

alter table npc_servicechecks add long_output TEXT NOT NULL default '' after output;

alter table npc_servicestatus add long_output TEXT NOT NULL default '' after output;

alter table npc_statehistory add long_output TEXT NOT NULL default '' after output;

alter table npc_systemcommands add long_output TEXT NOT NULL default '' after output;

执行这些语句，在重启nagios

[root@localhost soft]# service nagios restart

[root@localhost soft]# cat /var/log/messages

Jul  5 17:40:52 localhost nagios: ndomod: Successfully connected to data sink.  0 queued items to flush.

Jul  5 17:40:52 localhost nagios: Event broker module '/usr/bin/ndomod-3x.o' initialized successfully.

Jul  5 17:40:52 localhost nagios: Finished daemonizing... (New PID=12381)

Ndo2db启动成功，现在就可以看到NPC的数据了。
