Nagios Support Forum

Dear Team,


We have one NagiosXI system installed successfully in CentOS 6.3.
In other system we installed MySQL (CentOS) and offloaded db from NagiosXI.

We followed "Offloading_MySQL_to_Remote Server" this document for offloading database.

after offloading MySQL db we started mysqld service on both machine, and permanent on services on both nagiosxi and mysql system done.

now we facing issue in log messages ( file /var/log/message) like:

Sep 3 10:52:46 NagiosxiApp ndo2db: Error: mysql_query() failed for 'INSERT INTO nagios_systemcommands SET instance_id='1', start_time=FROM_UNIXTIME(1378185766), start_time_usec='243862', end_time=FROM_UNIXTIME(1378185766), end_time_usec='247657', command_line='/bin/mv /usr/local/nagios/var/service-perfdata /usr/local/nagios/var/spool/xidpe/1378185766\.perfdata\.service', timeout='5', early_timeout='0', execution_time='0.003000', return_code='0', output='', long_output='' ON DUPLICATE KEY UPDATE instance_id='1', start_time=FROM_UNIXTIME(1378185766), start_time_usec='243862', end_time=FROM_UNIXTIME(1378185766), end_time_usec='247657', command_line='/bin/mv /usr/local/nagios/var/service-perfdata /usr/local/nagios/var/spool/xidpe/1378185766\.perfdata\.service', timeout='5', early_timeout='0', execution_time='0.003000', return_code='0', output='', long_output='''
Sep 3 10:52:46 NagiosxiApp ndo2db: mysql_error: 'Table './nagios/nagios_systemcommands' is marked as crashed and should be repaired'

I am also attached log file which is contained last 1000 lines in from bottom side name "var-log-messages"

You can also find the screenshots which i attache in mail......

Please resolve this issue as soon as possible.

You should only be running these commands on the nagiosxi server:
Only start mysql on the remote host. To repair the database use this document:

Dear Team,

Thank you very much for replying.
I fixed this error, with the reference of your reply.

I done following things.....
in mysql database table it was showing "" NagiosxiApp ndo2db: mysql_error: 'Table './nagios/nagios_systemcommands' is marked as crashed and should be repaired' ""

i checked in my nagiosxi server's nagios tables named nagios_systemcommands and repaired, and then checked messages but still i was getting errors.

then i logged in Mysql server (which was offloaded for Nagiosxi Application)
and forcefully repaired nagios_systemcommands table with following commands:

logged in mysql server

# service mysqld stop
# cd /var/lib/mysql/
# myisamchk -r -f nagios/nagios_systemcommands.MYI
# service mysqld restart
# exit

then i checked in nagiosxi application server's log messages which was from /var/log/messages

Error FIXED...i think...........

# tailf /var/log/messages ( i was getting in nagiosxi app server)
