Nagios Support Forum

1. CentOS 6.0
2. 32-bit
3. VMware image from Nagios
4. No special configurations. Nothing has been done on the machine after installing Nagios.

After logging into Nagios XI, I receive an error message:

SQL: SQL Error [ndoutils] : Incorrect file format 'nagios_programstatus' SQL: SQL Error [ndoutils] : Incorrect file format 'nagios_programstatus'

I searched the Internet and found a PDF from Nagios that discussed running the following commands to repair the database. I ran them successfully but the error is still generated every time I log in:

service mysqld stop

/usr/local/nagiosxi/scripts/repairmysql.sh nagios *

service mysqld start

I searched the forum using keywords but didn't find any other post about this error message.

Do you know what the reason is and how I can resolve it? Thanks.

If you saw something similar to this:

SQL: DELETE FROM nagios_logentries WHERE logentry_time < FROM_UNIXTIME(1293570334)
SQL: SQL Error [ndoutils] :</b> Table './nagios/nagios_logentries' is marked
as crashed and last (automatic?) repair failedCLEANING ndoutils TABLE 'notifications'...

then, you may need to run a force repair on the tables: Hope this helps.

Thanks for the quick reply. I was hesitant to apply the suggestion because I didn't receive the kind of error you referenced. In any case, I tried to apply the suggestion but encountered the following error:

[root@mynagios ~]# service mysqld stop
Stopping mysqld: [ OK ]
[root@mynagios ~]# cd /var/lib/mysql/nagios
[root@mynagios nagios]# myisamchk -r -f nagios_programstatus
myisamchk: error: 'nagios_programstatus' is not a MyISAM-table

Am I not referencing the table correctly? From the error message that I mentioned, it appears the table's name is nagios_programstatus.

Run this command as root and report the output

Here is the result of the command:

[root@mynagios ~]# echo "USE nagios;show tables where Tables_in_nagios='nagios_programstatus';" | mysql -pnagiosxi

Tables_in_nagios
nagios_programstatus

Looks like there is a table named nagios_programstatus.

Ok, that's positive...

Now

Here is the result of the command:

[root@mynagios ~]# echo "USE nagios;select instance_id,status_update_time,program_start_time,is_currently_running from nagios_programstatus" | mysql -pnagiosxi

ERROR 130 (HY000) at line 1: Incorrect file format 'nagios_programstatus'

Please run

[root@mynagios nagios]# myisamchk -r -f nagios_programstatus
myisamchk: error: 'nagios_programstatus' is not a MyISAM-table

Just a note on this, it needs to be in on the <table_name>.MYI file. So for this circumstance it would need to be:

@mguthrie

Adding the extension you mentioned did not work. Here is the result:

[root@mynagios nagios]# myisamchk -r -f nagios_programstatus.MYI
myisamchk: error: 'nagios_programstatus.MYI' is not a MyISAM-table
